Product Code:SAE AIR4298
Title:Impulse Test Machine, Sine Wave, Equipment and Operation Of
Issuing Committee:G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
Scope: This SAE Aerospace Information Report (AIR) describes equivalent type equipment and operational guidelines for a standard sine wave impulse test machine. The machine may be used for testing hydraulic tubing, fittings, hose assemblies, and similar fluid systems components, if desired. The standard sine wave impulse test machine is established for the following purposes: 1. a design guide for future machines being built by manufacturers and users and 2. as a referee in the event of conflicting data from two or more nonstandard impulse machines. Such a referee machine might be built by an impartial testing activity.
