This procedure is intended to apply to all pumps down stream of engine inlet. The procedure will be defined in terms of recommended test setups and recommended testing methods. PURPOSE: This recommended practice defines procedures for testing aircraft fuel pumps for the purpose of comparing their resistance to deterioration@ during endurance test@ handling a specified mixture of gas and liquid expressed as a ratio of vapor volume to liquid volume. Method I procedure is based on the assumption that an acceptable V/L meter is available for use in conjunction with this test. The desired V/L can be determined by either of the two methods outlined herein: Method I@ V/L Meter; Method II@ Calculated V/L. The procedure recommended herein is based on experience gathered by a number of laboratories conducting component qualification tests to MIL-E-5009. It is intended to produce a uniform@ reproducible test condition as prescribed by paragraph 4.3.2.3.5 Fuel Pump Cavitaion@ of MIL-E-5009B. With modifications this procedure can be used for other engine specifications. The procedure recommended herein is intended to provide a test for the purpose of compliance with MIL-E-5009B within the scope of paragraph 1.2 above. This test in not intended to establish altitude or climb rate performance of the article tested.
