1 INTRODUCTION

1.1 DOCUMENT PRESENTATION

The purpose of this document is to collect common technical specifications for fire fighting vehicles used in ARFFS (Aircraft Rescue and Fire Fighting Services), in application of article D.213.1.7 in chapter III, book II of the Civil Aviation Code (part 3). It is applicable to these vehicles under the conditions defined by the National commission for airport safety equipments.

The requirements defined in this document must be understood as being minimums in terms of performance, safety and ease of use. Depending on the technical constraints specific to his application, a buyer may define more severe or complementary requirements for his own needs.

This document also describes compliance check tests to be performed on vehicles before they can be declared as compliant with specifications by the National commission for airport safety equipment. These tests will be carried out under conditions defined by the commission. They must not be confused with « acceptance » tests in which a buyer checks that the delivered equipment is conforming to his order.

A guide for buyers is given for information (chapter 13) so as to summarize the different points to be specified during an order for an ARFF vehicle.

1.2 DEFINITIONS

The definitions in documents S60-101-4, S60-101-8, NF EN 1846-1, NF EN 1846-2, NF EN 1846-3 and XP S 61-518 are applicable except for:

• Spray stream: used to replace « fog stream », due to the risk of confusion with other « fog » water devices.

• Usable capacity of a tank: quantity of liquid contained in a tank that can be used for discharging by the main nozzle of the vehicle (turret nozzle) at the nominal flow rate of this nozzle until the first time that the pump is unprimed.

The following definitions are also applicable specifically to ARFF vehicles:

• Hydraulic installation: system composed of storage containers, hydraulic elements and control and instrumentation equipment for supplying the various nozzles on a foam making vehicle with the foam solution in the required percentage, and at the required flow and pressure depending on the required performances.

• Water tank: storage container installed on a vehicle and containing water used to produce the foam solution.

• Foam concentrate tank: storage container installed on a vehicle and containing the foam concentrateused to produce the foam solution.

Note: the water and foam concentrate tanks are usually combined in a single physical assembly called the « tank », but this is not mandatory in these specifications.




• Turret nozzle: main nozzle on a foam making vehicle. The regulations require that only foam solutionflows produced by this nozzle (and the corresponding usable water capacity) are considered to determine the equipment to be supplied to an aerodrome to provide the required protection level.

• Bumper turrets, foam handlines: complementary nozzles, the flows available with those nozzles are not used to determine the equipment to be installed on an aerodrome to satisfy the required protection level.

• Undertruck nozzles: protection by discharging on the ground with the purpose of protecting the entire vehicle when passing over burning elements and/or pools of fuel (not to be confused with the «thermal protection» in standard XP S 61-518).

• Dry chemical installation: system composed of one (or several) storage containers, mechanical elements and control and instrumentation equipment in order to supply dry chemical to the dry chemicalhandline, at the required pressure in order to meet the required performances.

• Dry chemical handline: nozzle to discharge dry chemical. Only nozzle for vehicles fitted only with dry chemical (VIP).

• Driver: ARFFS personnel who can access the vehicle driving controls and fire fighting equipment controls from his seat.

• Operator: ARFFS personnel who can access fire fighting equipment controls from his seat. The operator may also need to get off the vehicle to use handlines or other equipment or accessories while the driver remains in the cab, or he may need to go to the operating station platform to use the vehicle in standby mode.

• Passenger: any other person(s) transported in the cab. These passengers do not need access to the controls and indicators for using the vehicle.

• Operating station platform: operating station for using the turret nozzle in standby mode.• Operating stations on the ground: operating stations for using foam handlines, the 65 mm additional

discharge pipe, suction from the outside or the dry chemical handline.• Standby mode: vehicle usage mode in which one (or several) automations or power assistance

nozzles available on the vehicle are defective. In these modes, the vehicle remains useable, but wholly or partly using manual control nozzles. Therefore the operational efficiency of work on an accident is necessarily lower in these modes.

• Standby manual control: the standby manual control may be done by a mechanical, electrical, pneumatic or hydraulic system or directly by manual force applied by the ARFFS personnel. These controls are used to double up an automatic control when there is one. However, standby powerassistance controls only rely on manual force applied by the ARFFS personnel.

2 GENERAL

2.1 SCOPE

The applicant (in the sense used in chapter 5 of the regulations for processing compliance certificate applications) is responsible for the vehicle design, construction and performances and for any sub-assembly even if it is subcontracted, except for products imposed by the buyer. He must assure that all elements supplied are new. He must assure that the vehicle and its permanently installed equipment is capable of satisfying these specifications and European or French regulations or standards in force, and in particular the following (non-exhaustive list):• European directives related to road vehicles;• European directives related to pressurized equipment;• European directives related to machines (so-called « safety of machinery » directives) ;• European directives related to low voltage electrical equipment;• Automobile Standardization Office Standards;• Electricity and Technical Union Standards;• Highway Code (apart from exceptions specified in note 25698, 1/10/1996).

When imposed by standards and regulations in force (see above), compliance of a vehicle, as promulgated by the National commission for airport safety equipments, remains subordinate to approval by organizations or the addition of CE marks for permanently installed equipment or for subassemblies on this vehicle.

For example, it remains subordinate to approval by the DRIRE (Regional Directorate of Industry, Research and the Environment) (e.g. Mines Service) for putting the vehicle on the road.

Consequently, compliance with these specifications does not necessarily imply compliance with requirements in the standards and directives mentioned above. Nor does it offer a pretext for avoiding satisfying them. However, although the standard reference for rescue and fire fighting vehicles (NF EN 1846-1, NF EN 1846-2, NF EN 1846/A1 and NF EN 1846-3) is not applicable to ARFFS vehicles, these specifications include references to the relevant sections in these standards whenever necessary.

2.2 USAGE CONDITIONS

These vehicles are designed for aircraft fire fighting on the ground. In accordance with the regulations, they may be used on an aerodrome and its immediate surroundings, on runways or surfaced tracks or non-pavedareas, during the day or night.

In order to simplify the use of foam making vehicles, fire fighting equipment must be provided with a automation system for the main functions including pressure regulations, and an automatic function to rinse the nozzles. They must be provided with a power assistance system for operation of the valves, and in some cases a power assistance system for handling the turret nozzle.

This automation system and these power assistance systems shall be provided with controls to enable a return to manual use of all operational functions of the vehicle.

2.3 WEATHER CONDITIONS DURING USE

These vehicles will be put into service on aerodromes in a wide variety of climates, such that vehicles, electronic systems and all connections have to be adapted to climatic conditions of use.




The climatic conditions of use are classified into three categories:• Cold zone: - 40°C to + 15°C ;• Temperate zone: - 15°C to + 35°C ;• Hot zone: + 15°C to + 60°C.

Vehicles are designed for use with standard industrial quality water.

2.4 CORROSION

Manufacturers’ attention is drawn particularly to the fact that these vehicles are frequently exposed to the weather under a variety of climatic and geographic conditions. Furthermore, due to conditions of use and personnel training, all this equipment is exposed to contact with extinguishing solutions with various different aggressiveness. A global surface treatment adapted to corrosion risks and dependent on the weather conditions in which the vehicles are used, shall be applied after complete assembly of the fire equipment on the cabin chassis subassembly.

Therefore, the manufacturer shall take special care with problems that arise due to corrosion of the chassis, metallic elements of the bodywork and fire fighting equipment. It is recommended that materials not severely affected by corrosion, stratified polyester and other plastic composites should be used.

Chapter 5.2.5 in NF standard EN 1846-2 is applicable for resistance to corrosion. The estimated life specified by the user shall be greater than or equal to 10 years.

2.5 GENERAL CHARACTERISTICS

Vehicles are coded by a group of letters and numbers, beginning with VI to denote a crash rescue vehicle and followed whenever necessary by:- the letter M for foam followed by the number of hundreds of liters of water available (usable water

quantity) for production of this foam, possibly rounded;- the letter P for dry chemical, followed by the number of hundreds of kilograms of dry chemical, possibly

rounded.

The vehicle code is indicated when the compliance certificate is issued.

Examples:- VIM 90 P 2.5: vehicle containing 9 000 liters of water usable for the production of foam and 250 kg of dry

chemical;- VIP2.5: vehicle containing 250 kg of dry chemical.

2.6 ROAD PERFORMANCES

Vehicles road performances shall satisfy the requirements given in the following table as a minimum.

Usable capacity in water(liters)

Acceleration time (in seconds) from 0 to 80 km/h

Maximum speed(in kilometers / hour)

Less than or equal to 4 500 l less than or equal to 25 s greater than or equal to 105 km/h

Greater than 4 500 l less than or equal to 30 s greater than or equal to 105 km/h

Vehicles containing dry chemical only are included in the first category: capacity ≤ 4 500 l.




It is prohibited to limit the speed of vehicles by construction (note 25698 date 1/10/1996 issued by the Ministry of Transport to the DRIREs (Regional Directorate of Industry, Research and Environment) summarizing various exeptions to the Highway Code applicable to rescue and fire fighting vehicle).

2.7 MOBILITY

All vehicles shall be constructed using single wheels (in other words with no dual wheels) and all wheels will be driving wheels. They shall be equipped with differential locking devices or any other equivalent equipment. They are used with independent control for locking between axles, between rear wheels and between front wheels.

Locking between front wheels shall depend on permanent action by the driver. However, a control without permanent action by the driver may be accepted provided that its use triggers a non-disengageable visual and sound alarme. Furthermore, this locking between wheels is not required for a vehicle with a total grossweight of less than 3.5 Tonnes.

2.8 CENTER OF GRAVITY

Stability must be optimized, firstly due to the high power of engines installed on aircraft rescue and fire fighting vehicles, and secondly due to the urgent conditions under which these vehicles are required to operate on aerodromes. Consequently, their center of gravity must be as low as possible while respecting:- the geometric characteristics of the chassis defined in these specifications;- the size defined in these specifications;- the maximum height of the center of gravity of the chassis with respect to the load distribution during

braking.

Vehicles shall have successfully passed the dynamic stability tests defined in this document (chapter 9).

Moreover, the side slope stability angle (see 9.3.1) shall be greater than or equal to the following values:

Usable water capacity(in liters)

Side slope stability angle(in degrees)

Less than or equal to 4 500 l Greater than or equal to 30°

Greater than 4 500 l Greater than or equal to 28°

Vehicles carrying dry chemical are included in the first category: capacity ≤ 4 500 l.

2.9 GAUGE

The overall height of the vehicle when empty shall be as low as possible and not more than 4.30 meters. The clearance circle between walls (defined in §3.10 in NF standard EN 1846-2) shall be less than three times the overall length of the vehicle.




3 CHASSIS AND MOTORDRIVE

3.1 MOTORDRIVE

The engine(s) conforming to French or European standards (as defined in the DRIRE report) shall be powerful enough for the vehicle to satisfy the required road and/or hydraulic performances for the vehicle as defined in these specifications. Its equipment shall enable start-up and normal operation at an ambient temperature within the limits specified for the usage zone of the vehicle at an altitude of less than 600 meters.

Gas exhausts from the engine(s) shall be arranged such that there is no risk of causing intoxication or burns for personnel working at operating stations during normal use of the vehicle. When exhaust pipes are in the lower part on the vehicle, they shall be provided with spark guards to prevent sparks being projected onto the ground.

The engines are fitted with a heating device. Engine compartments at the back of the chassis and separate engines (power-driven pumps) are provided with an emergency stop circuit breaker preventing use (even from the cab), in accordance with NF standard 418, class O (mushroom shaped red button, with no key, on yellow background, identified « emergency stop »).

Vehicles with a total gross weight of more than 3.5 Tonnes that are provided with an automatic hydraulic installation regulation system, shall be provided with a standby manual accelerator for the power-driven pump. This device shall be identified and sealed for a mechanical control, and in all cases the speed thus controlled by the driver shall remain stable without continuous action on the control.

Start prevention systems (anti-theft device) are not allowed, and if necessary they shall be disassembled or completely disabled.

3.2 TRANSMISSION

The gearbox is automatic for vehicles with a total gross weight of more than 3.5 Tonnes.

Vehicles are provided with a siren and a visual alarme system at the back, that operate whenever reverse gear is selected and are conforming with chapter 5.1.1.8 in NF EN 1846-2, regardless of the total grossweight.

3.3 WEIGHT DISTRIBUTION

The total weight of the fully loaded vehicle shall be distributed as equally as possible between the different axles and wheels, to assure good stability and a good motor drive with the vehicle in all configurations. To achieve this, this distribution shall respect the following criteria (loaded vehicles) for vehicles with a usablewater capacity of more than 4 500 liters:

- the difference in weight between the wheels on the same axle and for each axle shall not exceed 5% of the average weight per wheel of this axle.

- the weight difference between any two axles shall not exceed 10% of the weight of the heaviest axle, if the heaviest axle is the rear axle. This maximum difference is reduced to 5%, if the heaviest axle is the front axle.




Only the first criterion is required for vehicles with a usable water capacity of 4 500 liters or less.Vehicles carrying dry chemical only are included in the category : capacity ≤ 4 500 l.

3.4 CHASSIS GEOMETRIC CHARACTERISTICS

The geometric characteristics of the chassis with the loaded vehicle shall be as follows, to not hinder displacement of the vehicle off the road:

Usable water capacity Less than or equal to 4 500 l Greater than 4 500 l

Approach and departure angles(in degrees)

Greater than or equal to 30 ° Greater than or equal to 30 °

Ramp angle (in degrees)

Greater than or equal to 24 ° Greater than or equal to 24 °

Ground clearance and ground clearance under axles

(in meters)

Greater than or equal to 0.20 m Greater than or equal to 0.33 m

Diagonal opposite wheel motion(in meters)

Greater than or equal to 0.25 m Greater than or equal to 0.35 m

Vehicles carrying dry chemical only are included in the first category: capacity ≤ 4 500 l.The definition of the approach and departure angles, the ramp angle, ground clearance, ground clearance under axles and the diagonal opposite wheel motion are given in standard NF EN 1846-2, chapters 3.4 to 3.9.

3.5 BRAKES

The braking system shall be conforming to European Directive 71/320/CEE or the French regulations in force if the French regulations are more severe. Brakes are power assisted. The power assistance may be pneumatic, hydraulic or hydropneumatic. Braking is applied on all wheels and the system is designed such that a break in any one pipe will not cause total loss of the braking capacity. The design of the vehicle braking system shall be such that it also enables another vehicle stop, even when the engine is not running (this requirement is not applicable to vehicles with a total gross weight of less than 3.5 Tonnes).

The braking system shall be sufficiently leaktight to remain operational (in other words with the chassis safety device not activated) for 2 hours with the engine cut off, vehicle not connected to an auxiliary energy source and onboard electro-compressor deactivated. The parking brake shall be sufficient to keep the vehicle immobile at full load in a 20% slope.

During normal operation, the system must be capable of stopping the vehicle at full load under the following conditions:




Usable water capacity Test speed Maximum stopping distance

Less than or equal to 4 500 liters 32 km/h 11 meters

64 km/h 40 meters

Greater than 4 500 liters 32 km/h 12 meters

64 km/h 49 meters

Vehicles containing dry chemical only are included in the category with capacity ≤ 4 500 l.The brakes shall hold the vehicle during the test on a lane with a width defined by NF standard EN 1846-2, § 5.1.1.2.1.

When the vehicle is provided with pneumatic power assistance, the pressure must be maintained, on top of the engine driven compressor, in the cylinders by an onboard electric compressor capable of maintaining the air pressure in the braking system when the vehicle is parked in the garage for a prolonged period. It is then provided with a de-oiler and an air-dryer on the output. The system may be doubled up by a fast disconnection device connecting onto an external air circuit. The system is provided with an accessible takeoff point that will be used for inflation of the tires. Auxiliaries shall never be supplied with bleed air from tanks used for the braking system.

Vehicles with a total gross weight of more than 3.5 Tonnes shall also be equipped with:- a wheel antiblocking system;- an engine brake acting when the accelerator pedal is released.

3.6 SUSPENSIONS

The manufacturer’s attention is drawn to the impact of usage conditions of ARFFS vehicles on aging of suspensions. Unlike most other vehicles including structural fire fighting vehicles, these vehicles are almost permanently fully loaded with the tanks full and all of their accessories.

3.7 GREASING

Grease points shall be described in the vehicle technical instructions and shall be identified on vehicles by a yellow paint mark. Permanently installed equipment on the vehicle must never hinder access to the different grease nipples, filters, filling and drain orifices. A lubrication diagram on an indicating plate is fixed to the vehicle, even if the vehicle is fitted with a central lubrication system.

3.8 TIRES

The "Off Pavement" automobile characteristics mentioned above shall be such that the vehicle can clear obstacles that will normally be encountered on or near an aerodrome. Therefore, the vehicle manufacturer shall propose and define tire dimensions and profiles, to give the best compromise for the ground on which the vehicle will travel.Tire operational pressures (« mixed surface » or « pavec surface ») depending on the type of tire installed, are marked on the vehicle on a name plate, and preferably on the wheel arches.




3.9 ENDURANCE

The capacity of the fuel tank shall be sufficient to satisfy the stricter of the following two conditions:- a distance of 200 km on a road with a medium rough profile;- operation of the fire fighting equipment at its nominal characteristics for two hours.

The tank filling orifice shall be easily accessible to standard equipment used for this purpose, including the use of a jerrican. An indicating plate fixed nearby indicates the nature of the fuel.

3.10 TOWING

Vehicles shall be equipped with a towing device at the front and the back. Applicable forces shall correspond to the total weight of the gross vehicle. If shackles are used, each shackle and its attachment shall resist a tension force equal to half of the total allowable gross weight.

3.11 PROTECTION AGAINST FALLING OBJECTS

Manufacturers’ attention is drawn to the fact that in an aeronautical context, the loss of objects on runways leads to serious consequences. Consequently, the installation of protection devices (casings, nets, etc.) should be considered to limit the risk of objects getting lost on the runways.

3.12 ONBOARD PACKAGE

The vehicle shall be provided with the following minimum onboard equipment:• A tool kit,• a jack with bar and jack extension,• a tire-nuts wrench for changing the wheel,• a set of spare fuse for all models,• an inflation hose with an inflation handle and accessories (couplings, etc.) for use of an external air

supply or for a connection onto a braking circuit (vehicles with pneumatic power assisted braking),• an approved red-warning triangle.

These elements are not necessarily installed onboard the vehicle.




4 BODYWORK

6 HYDRAULIC INSTALLATION

This chapter contains specifications for fire fighting equipment (foam making part) for all vehicles designed to spray extinguishing foam (VIM).

6.1 GENERAL

The equipment is made so that it can be used with a foam concentrate with performance level B, as defined by the ICAO. It must be designed (with elements and crimping of nozzles permanently installed as described in chapters 6.8 to 6.13) to operate at the highest nominal working pressure plus 5.5 bars, with no damage. All pipes can be easily disassembled (flanges, unions) and are made according to standard practice with a material resistant to the aggressiveness of the foam concentrates.

Nozzles selected by the operator may be supplied with water or a foam solution. When the vehicle is switched on or when the pump is used, the hydraulic circuit will be pre-arranged unless selected otherwise by the operator to supply nozzles with a foam solution. However, the foam concentrate supply in the pre-mixing circuit will only be effective above 7 bars.

The installation is provided with a sufficiently large number of purge points so that draining is complete. These points are marked, identified and are easily accessible, and are isolated by 1/4 turn valves. The valves will be protected against all risks of getting caught and accidental opening if necessary.

The pump shall be capable of operating at its nominal flow for the turret nozzle, when the vehicle is on a slope of 40%.

The cooling system of the assembly shall be designed such that the pump can operate for at least two hours when stationary and in static mode (see test conditions in chapter 10.5).

The pump discharge pressure shall be modifiable by the user in static mode, from the instrument panel in the cab and at foam handlines operating stations. Its value shall be directly readable from the cab and at the foam handlines operating stations.

Indicating plates or ISO symbols identify all maneuvering valves and taps and specify precautions to be taken against frost. An indicating plate is fixed on the vehicle showing a general diagram of the hydraulic installation. All valves are provided with a mark indicating the « open » and « closed » positions.

6.2 PUMP

6.2.1 General

In all cases, it shall be possible to prime the pump by gravity from the water tank. The pump shall be primed by suction from an external water point in less than 40 seconds for a 6.50-meter suction lift.

Greasing points shall be easily accessible. The pump shall comprise an orifice near the bottom of the body from which it can be purged. The pump hydraulic circuit shall be designed such that a long term wait with the pump running at idle speed will not cause excessive overheating of the circulating water that could reduce the life of the pump. A warning light and a « high water temperature in the pump » buzzer must be provided in the cab.

6.2.2 Flow

The pump flow shall be sufficient to simultaneously supply the turret nozzle, a foam handline at fixed flow and vehicle undertruck nozzles, at nominal flow and at minimum throw range without the development of




cavitation phenomena. The pump shall be sufficiently powerful so that partial or full use of the nozzles does not cause a temporary variation of the pressure exceeding 25%.

6.3 HYDRAULIC CIRCUIT PRESSURIZATION PRINCIPLE

6.3.1 Pump driven by separate motor (called « power-driven pump »)

A reliable automatic control system (whith stand-by mode) shall be provided and designed so that it relieves the crew from all usage constraints related to mechanical requirements for this type of device. The motor driving the pump shall be supplied by the same tank as the traction engine when the two engines use the same fuel. However, the motor driving the pump shall always become unprimed before the traction engine.

The pump shall be capable of operating at its nominal flow for the turret nozzle when the vehicle is on a 40% slope. The cooling system for the assembly shall be designed such that the pump can operate at its nominal speed and flow for at least two hours when stationary. It shall be possible to engage the pump while the vehicle is moving.

A device shall prevent the starter from being used again when the power-driven pump is in operation. This motor shall be equipped with an overspeed limiter. It shall be possible to remove the motor without disassembling bodywork elements other than the cover of the power-driven pump itself. These elements shall be easily removable.

The heating system for this motor shall enable normal start up and normal operation at an ambient temperature within the limits specified for the vehicle usage zone. The motor cooling system shall be standalone and of the closed circuit type. Water from the pump shall not be used for cooling the drive motor.

Tests are carried out in accordance with the requirements in these specifications after the manufacturer has supplied a report certifying that the power-driven pump has been run in, in accordance with the recommendations of the pump motor supplier.

6.3.2 Pump drive by the traction engine

When the pump is driven by the traction engine, this device shall satisfy the following conditions:

A. It shall be fitted with a automatic control system (whith stand-by mode) and designed so that it relieves the crew from all usage constraints related to mechanical requirements for this type of device, and particularly speed conditions. This automation shall be associated with pressure regulation functions for the “pump and roll” displacement mode.

B. A control shall be available on the instrument panel for selecting one of the following three modes:Drive by the motor Switch indication Action

Wheels only Drive Normal vehicle movement with pump stopped.

Wheels and pump Pump and Roll Movement with pump running

Pump only Static Pump running vehicle stopped

When the travel speed is within the range specified below, the corresponding mode shall be effectively engaged in less than 15 seconds. (Note: vehicles with only « Drive » and « Pump and Roll » modes may be issued with a compliance certificate)

C. “Pump and Roll” mode shall be available both in forward running and in reverse running, with the turret nozzle in operation, with a variable displacement speed from 0 to not less than 8 km/h. The pump flow and the throw range of the turret nozzle shall not be noticeably modified by any modification to the power level requested by the driver to assure displacement of the vehicle. In “Pump and Roll” mode, the vehicle movement control will use the vehicle brake and accelerator in the same way as in Drive mode. It shall be possible to engage “Pump and Roll” mode when the vehicle is moving.




D. The change from “Pump and Roll” mode to Static mode or vice versa shall not interrupt discharging in progress.

6.3.3 Propulsion of foam solution by propellant gas

For usable capacities less than or equal to 150 liters, it only includes a fast opening single leaktight inspection door acting as a filling orifice, a drain pipe opening up under the chassis devices, a venting device limiting foam concentrate losses during vehicle tests and a device in the cab for checking the foam concentrate level at day or at night.

6.7 PROPORTIONING SYSTEM

This system produces a constant foam concentrate concentration in the water regardless of the nozzlesbeing used, including when several nozzles are used simultaneously. It may be hydraulic or electronic. The nominal concentration is fixed at 6% (the value obtained during the tests must be between 5.5% and 7% for the turret nozzle, front monitor, and bumper turret, and between 5.5% and 8% for handlines and undertruck nozzles). The nominal concentration shall be modifiable and changed to 3% (the value obtained during the tests shall be between 2.8% and 3.5% for the turret nozzle, front monitor, and bumper turret, and between 2.8% and 4% for handlines and undertruck nozzles).

8.5 CHANGES TO STANDBY MODE

Controls for changing foam making vehicles (VIM) over to standby mode shall be such that the operator can make this changeover simply and quickly. A single action is enabled for this purpose (push, pull, turn, etc.). However, they shall be protected against accidental manipulations. In this respect, a second action by the operator is acceptable. It must be possible to changeover to standby mode regardless of the operating condition of the vehicle (nozzles discharging or not). A malfunction of the automation shall never prevent the change to standby mode. Furthermore, these changes to standby mode shall be easily reversible so that they can be done at will for training or test purposes.

8.5.1 If the turret nozzle power assistance malfunctions

In this case, the operator shall act as follows to use the turret nozzle:• go to the operating station platform,• use the control to changeover to standby mode (disengage the power assistance),• bring the turret nozzle into the required direction manually (elevation and azimuth).The control for change over to standby mode shall be accessible from the operating station platform.Non-power assisted orientation maneuvers shall be possible in all cases applying a force not more than 15 daN at the end of the lever.

8.5.2 If the valve power assistance malfunctions

A changeover from power-assisted valve opening to standby mode (control in cab) will trigger the following events (this does not prevent the user from modifying these arrangements by standby manual controls):• full flow / half-flow device: returned to full flow,• solid stream / spray stream device: held in the position in which it was in at the time of the changeover

to standby mode,• water / foam device: returned to the water position,• water tank inlet valves and other valves: held in the position in which they were at the time of the

changeover to standby mode.Non-power assisted valve opening and closing maneuvers shall be possible in all cases applying a force not more than 15 daN at the end of the lever.

Standby manual control of the 2 systems (solid stream / spray stream and water / foam) and the water tank inlet valve is then triggered from the operating station platform. The nozzles discharge valves are then opened and closed using standby manual controls under the following conditions:• for the turret nozzle and undertruck nozzles: from the operating station platform;• for handlines: handline operating stations on the ground.

8.5.3 If the automatic control malfunctions

The discharge pressure is controlled by manual accelerators (on operating station platform, and in the cab). In general, this mode also triggers the changeover from power-assisted valve opening to standby mode. In this case, the automatic control triggers unlocking of the turret nozzle and starts up the pump; standbymanual controls in the cab must be installed for these two functions.




8.6 RINSING CYCLE

Considering the corrosiveness of foam concentrates and the need to rinse the circuits after each use, foam making vehicles (VIM) provided with an automatic control shall be provided with an automatic function to rinse the nozzles. This rinsing cycle shall be configured such that it consumes less than the usable capacity of the water tank.

The rinsing cycle shall be done in an automatic sequence without any action by the operator after its start-up. Nevertheless, the operator must be able to interrupt the cycle at any time for obvious safety reasons.

Foam making vehicles shall be fitted with an alarm informing the operator about the need to rinse the vehicle. This alarme shall be maintained as long as the vehicle has not been completely rinsed.

8.7 PRIORITY OF PRESSURES

The nominal working pressures of nozzles on foam making vehicles (VIM) may be different in different nozzles. If several nozzles are used simultaneously, the priority to be applied by the automation is as follows (in decreasing order):• Turret nozzle,• Front monitor on articulated boom,• Bumper turret,• Handline with fixed flow,• Handline with variable flow,• Undertruck nozzless,• Additional DN 65 discharge.

9 COMPLIANCE TESTS: ROAD PART (1/2)

The tests defined in this chapter may take place:• either in a test center under the conditions defined by the CNMSA;• or at the manufacturer (or on a site defined in agreement with office services) when he has his own

suitable test installations or when he can obtain other suitable installations, under the control of the STAC (Civil Aviation Technical Services).

Their purpose is to characterize the performance of the vehicle on the road and to check the performance level achieved compared with the requirements in this document (refer to the corresponding chapters).

All tests take place on the vehicle loaded (equipment and accessories in place, tanks full). However, since the fordability test on a 40% ramp takes place with the turret nozzle in operation, the vehicle will only be loaded at the beginning of the test (when starting on the ramp). When the tests produce measurements of specific values, the margin of error of the measurements shall be specified.

9.1 CHARACTERIZATION BY WEIGHT

The purpose of this test is to determine the total weight, the distribution of weight on the wheels and the position of the center of gravity in the horizontal plane.

9.2 VEHICLE GENERAL PERFORMANCE

Examination of the performance of the vehicle, the equipment and loading (minimum passage speeds are indicated if necessary) for:• a typical road circuit,• a typical off road circuit (minimum 30 km/h),• five ford crossings, at least as long as the vehicle (depth 0.40 meters for vehicles with a total gross

weight less than 3.5 T and 0.60 meters for other vehicles) (minimum 10 km/h),• three passes over damaged road surfaces, passages and surfaces defined in Appendix D in standard

XP S 61-518 (sinusoidal and potholes) or equivalent (minimum 30 km/h).

Fordability test on a 40% surfaced ramp (+/- 2%), with the turret nozzle in operation, with the vehicle stopped and restart in the slope, in the up and down directions.

9.3 VEHICLE STABILITY

9.3.1 Static stability

The vehicle is placed on a tilting plate and is retained by appropriate devices. The height of the retaining blocks is fixed at 50% of the measured height to the rim, from the ground. Tipping is considered to have occurred as soon as the first wheel on the high side has lifted off the ground.
