Product Code:SAE J1959
Title:Test Procedures for Determining Air Brake Valve Input-Output Characteristics
Issuing Committee:Truck And Bus Brake Supply And Control Components Committee
Scope:This SAE Recommended Practice establishes uniform test procedures for determining input-output characteristics for those pilot-operated and mechanically actuated, modulating-type valves and through-type valves used in the service brake control system.Input-Output CharacteristicsCrack (opening) pressure or forcePressure differential (input-output)Hysteresis (increasing-decreasing pressure)Pilot-Operated Modulating-Type ValvesRelay ValveRatio relay valveDecaying ratio relay valveBooster relay valveRelay Valve with two-way check valveRelay EmergencyMechanically Actuated Modulating-Type ValvesDual service brake valveThrough-Type ValvesQuick release valveTractor protection valveLimiting valveGladhand with quick release valveModulator Valve (ABS)Tractor protection valve with two-way check valve(s)PurposeThis document is intended as a guide toward standard practice but may be subject to frequent change to keep pace with experience and technical advances, and this should be kept in mind when considering its use. This document provides a uniform definition of input-output characteristics of pneumatic valves designed to operate in 862 kPa (125 psi) nominal pressure air brake systems and establishes uniform test procedures to determine these characteristics. This document serves as a supplement to SAE J1409.
