Title:Air Brake Valves Test Procedure
Issuing Committee:Truck And Bus Brake Supply And Control Components Committee
Scope:This SAE Recommended Practice establishes uniform test procedures for air brake systems pneumatic valves with respect to:a. Input-Output Characteristicsb. Leakage Measurementc. Low Temperature Evaluationd. Elevated Temperature Evaluatione. Corrosion Resistance Evaluationf. Endurance Testingg. Structural IntegrityThis document establishes uniform accelerated laboratory test procedures for evaluating comparative performance characteristics of pneumatic valves designed to operate in 862 kPa (125 psi) nominal air brake systems. These tests are based upon long standing industry practices.
