This SAE Recommended Practice establishes uniform test procedures for air brake systems pneumatic valves with respect to:
a. Input-Output Performance
b. Leakage Characteristics
c. Low Temperature Evaluation
d. Elevated Temperature Evaluation
e. Corrosion Resistance Evaluation
f. Endurance Testing
g. Structural Integrity
h. Vibration Testing
Rationale: This document has been updated in keeping with the five-year review process. The Supply and Controls Components Committee has approved the addition of vibration testing per Section 11 and a temperature change from 38 °C (100 °F) to 43.3 °C (110 °F) in 3.1.
