Air Reservoir Capacity Performance Guide-Commercial Vehicles
This SAE Recommended Practice establishes performance guidelines for the capacity of the air reservoir systems used on trucks, towing trucks, truck-tractors, trailers, and converter dollies, with GVWRs over 10 000 lb, designed to be used on the highway in commercial operations.
The purpose of this document is to establish a minimum air storage capacity for highway-type commercial vehicles which use compressed air to actuate or transmit actuation power to the foundation brakes. A vehicle's air reservoir capacity is quantified by its ability to provide a brake application pressure which is adequate to stop the vehicle within the emergency brake stopping distances specified in table II of FMVSS 121, after seven full brake applications with the air compressor disabled.
Data Sets - Support Documents
The Truck and Bus Supply and Control Components 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 braked vehicles supply and components and their interfacing as utilized on trucks, tractor-trailers combinations and buses over 4,536 kilograms (10,000 lbs.) GVWR. The activities of this Committee include brake supply and control components and their interfacing, and is not, in any way, to duplicate efforts of any other Committees.
