Air Brake Actuator Test Procedure, Truck-Tractor, Bus, and Trailers

- Revised
Sector:
Issuing Committee:
Language:
English
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.
Rationale
New changes addressed requests to increase the Salt Spray Requirements, add Vacuum Requirements to Boot Seal Validation, allow longer pressure stabilization times during leak testing, add allowable cooling time between mechanical release test cycles, allow optional 5 Gallon Air Tank reservoir for pressure decay leak testing, standardize incremental measurements to 5 mm (0.20 in), and add Arctic temperature Leakage and Operational testing to allow the SAE J1450 specification to be suspended or cancelled.

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.
