Title:Off-Vehicle Brake Testing for Service Brakes over 10 000 lb GVW--Air, Hydraulic, and Mechanical Actuation
Issuing Committee:Truck And Bus Brake Systems Committee
Scope:Subject document is specifically intended for service brakes and service brakes when used for parking and/or emergencybrakes (only) that are commonly used for automotive-type, ground wheeled vehicles exceeding 4536 kg (10 000 US lb)Gross Vehicle Weight Rating (GVWR). Subject specification provides the off-vehicle procedures, methods, and processesused to objectively determine suitability of tactical and combat ground wheeled vehicle brake systems and selectedsecondary-item brake components (a.k.a. aftermarket or spare parts), including brake “block” for commercial applicationsonly, specifically identified within subject document. Subject specification is primarily based on known industry andmilitary test standards utilizing brake inertia dynamometers. Targeted vehicles and components include, but may not belimited to the following:a. Civilian, commercial, military, and militarized-commercial ground wheeled vehicles such cargo trucks, vocationalvehicles, truck tractors, trailers, specialized support and engineering equipment under the generic heading of GroundVehicle “Dry” Brake Systems (GVDBS).b. Hydraulic, air, and mechanical “dry” disc brake and drum brake systems when used as service brakes, includingservice brakes (only) when used as emergency and/or parking brakes.c. Hydraulic, air, and mechanical “dry” disc brake pad assemblies and rotor assemblies.d. Hydraulic, air, and mechanical “dry” drum brake shoe assemblies and drum assemblies.e. Hydraulic, air, and mechanical brake “block” when intended for use on a. thru d. above except for those vehicles, padassemblies, and shoe assemblies specifically procured for military use and/or tested under ATPD-2354. It must benoted that such the US Government’s Military Services buys only assemblies and doesn’t normally use “brake block”and relined brake shoes/pads, therefore testing using separate brake “block” was specifically excluded fromATPD-2354 by the original authors.【英文标准名称】:SamplingGasfromaTransformer
