Product Code:SAE J1911
Title:Test Procedure for Air Reservoir Capacity--Truck and Bus
Issuing Committee:Truck And Bus Brake Supply And Control Components Committee
Scope:This SAE Recommended Practice provides instructions and test procedures for air braked vehicles including but not limited to trucks, truck-tractors, trailers, dollies, and buses used on highways but does not include off-highway vehicles.PurposeThis document provides a method of determining the air reservoir capacity of highway type vehicles using compressed air to actuate or transmit actuation power to the foundation brakes. Air reservoir capacity is the ability to provide adequate brake pressure after a number of brake applications.【英文标准名称】:StandardTestMethodforNondestructiveAnalysisofSpecialNuclearMaterialsinHomogeneousSolutionsbyGamma-RaySpectrometry
