This aerospace specification defines the requirements for metric weld fittings and machine weldments using an orbiting welding head suitable for use on cold worked 3A1-2.5V titanium and 21Cr-6Ni-9Mn CRES tubing and associated fittings. This specification is equivalent to AS1576 except for metric dimensions and standards.
This aerospace test standard establishes the requirements and procedures for evaluating and comparing the impulse fatigue performance of high pressure hydraulic fittings and tubing. This test method may be used to test similar fluid system components, if desired.
This Aerospace Standard covers hose assemblies intended for use in aircraft high temperature fluid systems. The specified temperature range is -55°C (-67°F) to +204°C (400°F). Operating pressures are listed in Table I.
This standard provides an environmental performance test method for thermal shock testing of fluid system piping and fittings, excluding hose and hose assemblies.
This recommended practice establishes vibration and transmissibility test procedures which compare the relative strengths of various loop and saddle type support clamps. This procedure is intended for conducting fatigue testing which is standard throughout the aerospace industry thereby establishing a clamp strength comparison which can be used in an evaluation process. The testing required by this recommended practice ensures that clamps will meet adequate fatigue requirements only. It does not infer qualification of the clamp installation techniques or its ability to meet in-service environments or operating conditions. Separate qualification testing should be performed to ensure satisfactory service of the installed clamp.
This recommended practice establishes a flexure test procedure for determining the fatigue strength of bent hydraulic tubing. The procedure is intended for conducting flexure fatigue testing of hydraulic and pneumatic tubing to determine the effects of tube fabrication methods, surface finishing, and other processing techniques on the fatigue performance of the tubing. A mean stress is applied by holding system pressure in the specimens and flexing in a rotary flexure test machine.

This recommended practice establishes the requirements and the procedures for impulse testing of hose assemblies, tubing, and fittings for use in aerospace hydraulic systems of 4000 psi nominal operating pressure or less. It also refers to standard impulse test equipment to be used in conducting these impulse tests.
