Product Code:SAE J1469
Title:Air Brake Actuator Test Procedure, Truck-Tractor, Bus, and Trailers
Issuing Committee:Truck And Bus Brake Actuator Committee
Scope:This SAE Recommended Practice provides procedures and methods for testing service, spring applied parking, and combination brake actuators with respect to durability, function, and environmental performance. A minimum of five test units designated A, B, C, D, and E are to be used to perform all tests per 1.1 and 1.2.Test ProceduresLeak rate-parking and service chambers (Section 4)Chamber volume-parking and service chambers (Section 5)Maximum release and hold-off pressure-parking chamber (Section 6)Force output and stroke-parking chamber (Section 7)Force output and stroke-service chamber (Section 8)Low temperature leakage-parking and service chambers (Section 9)Low temperature maximum release and hold-off pressure (Section 10)Low temperature force output-parking chamber (Section 11)Low temperature operational test-service chamber (Section 12)Corrosion resistance-parking and service chamber (Section 13)Mechanical back-off release mechanism (Section 14)Proof pressure test-parking and service chambers (Section 15)Cycle test-parking chamber (Section 16)Cycle test-service chamber (Section 17)Elevated temperature cycle test-parking and service chambers (Section 18)Vibration test (Section 19.1)Test Sequence ChartThe test sequence as charted in the òTest Sequence Chartó shall be mandatory (see Figure 1).PurposeThis document provides uniform procedures and methods for laboratory testing of brake actuators used in air brake systems.?TEST SEQUENCE CHART
