lndian Standard
SPECIFICATION FOR IGLOO
PART 1 NON-STRUCTURAL IGLOO
0. FOREWORD
0.1 This Indian Standard was adopted by the Indian Standards Institu- tion on 30March 1984, after the draft finalized by the Air Cargo Handling Sectional Committee had been approved by the Marine, Cargo Movement and Packaging Division Council.
0.2 Igloos are intended to protect the interior of aircraft from damages and to provide a framework container into which cargo can be loaded. Igloo is a shell part of an integral aircraft unit load device assembly consisting of a pallet, net and igloo. Non-structural igloo is a bottomless rigid shell and a net is always used to secure this shell to the pallet.
0.2.1 In this Part 1 of the standard, requirements of non-structural igloo have been covered; structural igloo’s requirements have been laid down in Part 2 of this standard.
0.3 In order to facilitate international co-ordination on the subject; this standard is based on, the IATA specification 5013 for non-structural igloo, issued by the International Air Transport Association ( IATA ).
1. SCOPE
1.1 This standard ( Part 1 ) specifies the general structural igloo.
2. TERMINOLOGY
requirements for non-
2.1 For the purpose of this standard, the definitions given in IS : 7073 ( Part 1 )-1973* shall apply.
3. GENERAL REQUIREMENT
3.1 The base pallets size for the non-structural igloos shall be as per IS : 7074 ( Part 1 )-1973i.
*Glossary of terms relating to air cargo pallets and containers: Part 1 Air cargo pallets.
*Air cargo pallets : Part 1 General requirements.
3
IS : 10869 ( Part 1) - 1984
3.2 The contoured shell shall be constructed of rigid material which will withstand normal wear and tear during transport frorn shipper’s premises by surface and air to final destination at consignee’s premises.
3.3 The unit shall be weatherproof and the design shall provide for water run-off and ensure that contents of the igloo remain dry during outside handling or storage in rain, snow and windy conditions.
3.4 All lower corners of the igloo shall have a radius of at least 25 mm to provide clearance for the pallet corner edges.
3.5 The igloo contours shall be in accordance with Fig. 1 to Fig. 10. All dimensions shown are external maximum and provide the minimum acceptable aeroplane clearness and any deviations or tolerances shall be to the lower side to prevent reduction in clearances. The external volumes of non-structural igloos are given in Table 1.

3.6 A fixed length restraint chain may be installed across the forward open end. It shall be attached to each side of the front frame to prevent deflec- tion of the unit. If the igloo is not equipped with a chain restraint, the Igloo structure shall be sufficiently strong to meet the test requirements.
3.7 The igloo shall be attached to the pallet seat track to afhx the bottom edge ~of the igloo to the pallet.
3.8 Tare mass of the igloo shall not exceed 10-a kg/m8 of external volume.
4
IS : 10869 ( Part 1 ) - 1984
3.9 One long side of the igloo shall permit access into the unit. Preferably this side may be provided with a door or cover to meet the weather protection requirement. If so equipped, it shall be constructed of materials that are to meet with the appropriate airworthiness regulatory body’s requirements.
3.10 Provisions may be made for closing and sealing the igloo in combi- nation with the pallet and net to meet custom clearance requirements.
4. TESTING
4.1 The igloo shall be sufficiently rigid to provide protection to the air plane interior during all loading and unload;ng handling. Tests shall be conducted with the chain ( if fitted ) attached to the igloo and the igloo attached to the pallet as follows.
4.1.1 With a 91 kg downward load applied to the roof at the centre of the open side, no more than 50 mm downward deflection and no more than 25 mm lateral deflection shall occur at any point around the igloo.
4.1.2 A 273 kg horizontal load shall be applied to one contoured side of the igloo distributed as follows:
91 kg at the open edge, 91 kg at the centre and 91 kg near the aft edge. Each 91 kg load shall bear evenly on a 5 1 x 51 cm cross-section placed so that the load is concentrated in an area without beams at opening and aft and the remaining load concentrated at the ccntrc. The load shall be applied in a zone between 64 and 114 cm above the pallet. Under these conditions the horizontal deflection of the igloo at any point shall not exceed 50 mm.
4.1.3 The above deflections shall not cause permanent deformation and the igloo shall return to its original contour when the load is removed.
5. MARKING
5.1 Minimum Marking Requirements - Following marking for these non-structural igloo assemblies shall be shown on the top lrft hand on all four corners of the non-structural igloo assembly in such a manner that good readability is ensured under all phases of handling. Lettering should not be less than 25 mm high.
