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 Procedures
Leak 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 Chart
The test sequence as charted in the ÒTest Sequence ChartÓ shall be mandatory (see Figure 1).

Issuing Committee
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.
