5、affirmed 2014-10 Superseding J1609 FEB2010 Air Reservoir Capacity Performance GuideTrucks and Buses RATIONALE J1609 has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE This SAE Recommended Practice establishes performance guidelines of the air reservoir systems used on truck
6、s, towing trucks, truck-tractors, trailers, and converter dollies with GVWRs over 10 000 lb designed to be used on the highway. NOTE: Compliance with this document does not guarantee compliance with the air reservoir requirements of FMVSS 121. 1.1 Purpose The purpose of this document is to establish
7、 a minimum storage capacity for highway-type trucks, buses, trailers, and converter dollies which use compressed air to actuate or transmit actuation power to the foundation brakes. A vehicles air reservoir capacity is quantified by its ability to provide a brake application pressure which is adequa
8、te 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. 2.
