4 EPREUVE PNEUMATIQUE:
4.1 Imposition du code ASME pour la pression dpreuve
Rfrence lASME B31.3, les valeurs de pression dpreuve sont dfinies suivant la formule :P preuve = P x 1,1
P = Pression maxi de service
Suite la parution de la fiche CLAP 264, (CLAP = Comit de Liaison des Appareils Pression) ceparagraphe 4.1 nest plus en vigueur, et le 4.2 ci-aprs est considrer imprativement.
4.2 Imposition suivant les instruction PED pour la pression dpreuve
Rfrence au CLAP Fiche N 264 i, version 1 dite sous Orientation 8/16, du 19/01/2005, les valeurs
donnes lannexe 1 7.4 des Directives Europennes 97/23 CE du 29/05/97 doivent tre utilises pourla pression de test pneumatique.
En clair, les valeurs de pression dpreuve pneumatiques sont identiques celles de lpreuvehydraulique.
4.3 Dure
Lpreuve est ralise avec de lair comprim dans les mmes conditions que 3.3 ci dessus, mais pourune dure de 10 minutes.
4.4 Condition dpreuve
Que lessai soit pneumatique ou hydraulique, lorsque la valeur de la pression ne peut tre celle dfinie

5 TEST DETANCHEITE (TEST DE FUITE)
Le test dtanchit, appel leak test en anglais, est effectu aprs les preuves hydrauliques, sur unsystme complet pour contrler la bonne tanchit des assemblages et vrifier ainsi le bon serrage des
connexions, raccords et joints.Le test dtanchit nest pas obligatoire et ne remplace en aucun cas lpreuve hydraulique,
Le test de fuite est applicable uniquement pour des circuits dont la pression dpreuve hydraulique tique estsuprieure la pression dpreuve dfinie ci dessous.
5.1 Pression dpreuve et Fluides utiliss
La pression dpreuve est de 3,4 0,2 bar, le fluide utilis est de lair comprim.
5.2 Condition dpreuve
Lessai est ralis sur une tuyauterie compltement assemble avec ses propres composants. Les
vannes sont ouvertes de manire permettre le passage de lair comprim. Les extrmits sontbouches par des brides ou des systmes adquats, supportant la pression dessai, et non gnrateur defuite.
Lpreuve est ralise sur une dure de 15 minutes.
5.3 Rsultat dessai
Lessai est concluant si la fuite dair constate est infrieure 5 ml/min (5 Ncm3/min)
Cela correspond, par exemple pour un circuit de capacit infrieure 20 litres, une pression finale (3,4bar) gale la pression initiale (3,4 bar), conditions atmosphriques constantes.

SECTION 1E - ENGLISH
1 SUBJECT:
The present instruction concerns piping hydrostatic tests prior to operation.
It covers, in general, all piping assembled on the gas turbine and accessories bases and all interconnectionpiping for gas turbine frame 9E.
Instructions for the functional testing of each of the individual systems involved are covered in model listitems 0202 and 0203, test instructions for accessories and control respectively.
Following are the requirements for the testing of piping.
2 GENERAL POINTS:
2.1 Definition of hydrostatic and pneumatic tests
Piping hydrostatic and pneumatic tests are :
Hydraulic test: carried out at 1.5*times the nominal design pressure, with a liquid, compressedair or inert gas (*refer to the formula here below). They guaranty the mechanical integrity of thepiping.
This pneumatic test is an alternative to hydraulic test (see 4.2).
Leak test: carried out with compressed air at low pressure, usually at pressure lower than pipingnominal design pressure, to verify the piping after reconfiguring.
2.2 General point
Piping hydrostatic tests shall be performed in accordance with ASME B31.3.Piping hydraulic test is required with the exception that specific hydrostatic tests or 100% radiography ofall welded joints may be substituted where hydrostatic tests are impractical according to Europeandirective 97/23 3.2.2.
Refer to 3.5 (current specification) for further details.
The pressure test values for hydraulic or pneumatic tests are listed in table 1 here after. All the pressurevalues given in the present document are gage pressure. Absolute pressures are identified by bar abs. orpsia.
Hydraulic (or pneumatic) test shall be done before flushing. The intent of this requirements is to allowleaks detection, if any, and make the necessary repairs prior to cleaning the systems.

3 HYDRAULIC TEST:
3.1 Pressure test value
Pressure values shown on table 1 are defined by:P test value = P x 1.5 x S/St
P = Maximum operation pressure (bar)S = Steel allowable stress at ambient temperature (ASME B31.3 table A.1)St = Steel allowable stress at maximum operation temperature (ASME B31.3 table A.1)
Pressure values are given for a test fluid at temperature between 4C (39F) and 37C (100F).
3.2 Fluid for testing
Hydraulic test is carried out using drinking water or fluid identified in table 1.
3.3 Test condition
Hydraulic test happens at the end of piping manufacturing and welding, on piping section or full systempiping with valves, instrumentation and bellows (if necessary) removed.
Flanges connections on pipe are to be blanked off with appropriate blind flanges. Treaded connectionsare to be plugged with appropriate steel plugs.
Hydraulic test duration is 30 minutes.
3.4 Test result
No pressure variation is permitted during the duration of the test except due to atmospheric conditionsvariation: pressure and/or temperature. No leak is permitted. If test pressure drops for piping leakage it
shall be repaired and the test repeated.
A comprehensive test report of hydraulic test shall be issued for each piping or length of piping involved.. As a minimum, the test report shall include the date of the test, the test pressure at the beginning of thetest, the test pressure at the end of the test, the duration of the test, the inspectors name and the testedpiping reference.
3.5 If tests are impractical
If the test is impractical for technical reasons and in order to reach a security level similar, it is required:
-the voucher justifying the impracticability-100% visual test of weldings
-100% liquid penetrant test or magnetic particle tests-10% X-ray or ultra-sound, for components which do not need particular care (ex : low-pressure fluidsexcept gas and fuel)-100% X-ray or ultra-sound for components which need a particular care or built on site. (ex : gas, hotpiping under high-pressure such as exhaust air, bleed heating, etc

4 PNEUMATIC TESTS
4.1 FYI : Pressure test value according to ASME code
According to ASME B31.3, the pressure values shown on table 1 are defined by :
P test value = P x 1.1
P = Maximum operation pressure (bar)
Further to the issue of CLAP form 264, (CLAP = Comit de Liaison des Appareils Pression), this 4.1 isnot in force, and 4.2 hereafter must be taken into account.
4.2 Pressure test value according to PED instructions
According to CLAP form n264 I, version 1 published under Orientation 8/16, of 2005, January 19th,values given in appendix 1 7.4 of European Directives 97/23 CE of 1997, May, 29 thshall be used for thepneumatic test pressure.
I.E. the pneumatic pressure values are similar to the ones of the hydraulic tests.
4.3 Duration
Pneumatic test is carried out with compressed air or inert gas in the same conditions as 3.3 above,except for the duration: 10 minutes.
4.4 Test condition
Whether the test is pneumatic or hydraulic, when the pressure value can not be the one defined inappendix 1 7.4, additional measures shall be taken to check the behaviour under pressure, tightnessincluded (see CLAP 159 orientation 5/3).
4.5 The pneumatic test is very hazardous
The pneumatic test is very hazardous and requires particular cares. It is usually not used. It is givenhere for information.
It is absolutely recommended to consult notified national authorities for the rules or advices on theinstructions to be followed It is absolutely recommended to consult notified national authorities forthe rules or advices on the instructions to be followed Design Qualification Inspection and TestRequirements:

5 LEAK TEST
Leak test is carried out after hydraulic test on a system piping to check circuit tightness at piping flanges,connections, couplings and gaskets.
Leak test is optional and in any case do not supersede hydraulic test
Leak test is applicable only on piping where hydraulic pressure test value is higher than leak test pressuredefined here below.
5.1 Pressure test value and test fluid
Pressure test value is 3,4 0,2 bar (50 3 psi), test fluid is compressed air.
5.2 Test condition
Leak test is carried out on a system fully assembled including the components. Valves are open to allowcompressed air to flow through. End of piping are blanked using blank flange or adequate means tosupport the test pressure and are free of leak.
Test duration is 15 minutes.
5.3 Test result
Leak test is acceptable if air leakage is lower than 5 ml/min (5 Ncm3/min)
e.g. : this is corresponding to same pressure value at the end of the test (3.4 bar) as at the beginning (3.4bar) for a piping volume lower than 20 liters (0.235 gallon) with no atmospheric condition variation.
