Air Brake Actuator Test Performance Requirements - Truck and Bus
J2318
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 J1469 is being revised to add upper limits to the caging time in Section 5, 7 and adding a 69 kPa [10 psi] requirement to section 7.2. This revision added the 69 kPa requirement to Table 3. Section 7.1.1 is also updated to state "24-192 hours"
