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 six test units designated A, B, C, D, E, and F are to be used to perform all tests per 1.1 and 1.2.
This revision adds a test unit “F” for corrosion testing which allows future reference to SAE J2721. Made optional the parking volume reporting. Added high pressure service side cycles as prep for current cycle testing. Added requirements to read and record SAE J2899 rated stroke marking after corrosion test. Reorganized test order such that proof pressure is done at the end of test. Reorganized test order such that volume testing is done after low temperature testing. Made optional the minimum pressure response. Removed Disc Brake sections as it has been moved to SAE J2902. Made optional the low temperature parking force and hold-off. Made artic leak an alternative test procedure. Added 130 psig pressure test condition to Force output – Service Chamber.

Truck and Bus Brake Actuator Committee
The Truck and Bus Brake Actuator Committee of the Truck and Bus Brake and Advanced Driver Assistance Systems Steering Committee is responsible for developing, reviewing, and approving recommended practices, standards, and information reports related to air brake actuators and their interfacing as used on trucks, tractor-trailer combinations and buses over 10,000 lbs (4500 Kg) GVWR designed primarily for highway use.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
