Product Code:SAE ARP4014
Title:Aircraft Turbine Engine Pneumatic Component Contaminated Air Endurance Test
Issuing Committee:Ae-5b Engine Related Components Airframe-Mounted Pumps
Scope: This recommended practice describes a method of conducting an endurance test using contaminated air when the applicable specification requires non-recirculation of the contaminants. The objective of the test is to determine the resistance of the engine mounted components to wear or damage caused by the contaminated air. The method described herein calls for non-recirculation of the contaminants and is intended to provide a uniform distribution of the contaminant at the inlet to the Unit Under Test (UUT). The UUT may require the use of a hydraulic fluid for actuation of components within the test unit. Contamination of this test fluid is not part of this recommended practice, however, if required by applicable test specification refer to MAP 749A.
