Scope
This procedure provides test performance requirements for service, spring applied parking, and double diaphragm combination air brake actuators with respect to durability, function, and environmental performance when tested in accordance to SAE J1469.
Rationale
SAE J2318 provides test performance requirements for SAE J1469, “Air Brake Actuator Test Procedure, Truck-Tractor, Bus, and Trailers”. This revision reflects the revisions made in SAE J1469, namely to include the special needs of an actuator when mounted to a disc brake caliper. In addition, modifications were made to the parking force table format and service force table format for improved standardization and ease of use. The service force table also included corrections to the data values and added some sizes that are commonly used with disc brakes. Finally, a revision to provide the minimum acceptable vibration performance was added and the requirement to meet “out of box” force requirement cycle testing parking springs 200K cycles was rescinded.

* 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.
