Scope
This SAE Recommended Practice (RP) provides test procedures for air braked trucks and truck-tractors used to tow single and multiple trailer combinations on highways. This RP is not intended for off-highway applications.
Rationale
This document provides a method of determining the capability of towing trucks and truck-tractors to supply compressed air to the reservoirs and parking brake chambers on towed vehicles. This is a test procedure only and it does not have criteria for data comparison. Therefore, the usefulness of the procedure is to evaluate air system changes relative to each other.
The test reservoir assembly is to simulate the supply system of a trailer. The 49 170 cm3 (3000 in3) reservoir is typical for four type 30 service chambers. The orifice in the line is to simulate the value through which the reservoir fills and the 9.84 mm (.3875 inch) diameter x 13.72 meters (45 feet) long tube is intended to duplicate the trailer supply line.

Truck and Bus Brake Systems Committee
The Truck and Bus Brake Systems Committee of the Truck and Bus Brake and Stability Control Steering Committee is responsible for developing, reviewing, and approving recommended practices, standards, and information reports related to brake systems of 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.
