This SAE Recommended Practice establishes minimum performance requirements for new pneumatic valves when tested in accordance with the test procedure outlined in SAE J1409. The performance requirements will include: a Input-output performance b Leakage characteristics c Low temperature performance d Elevated temperature performance e Corrosion resistance performance f Endurance testing g Structural integrity

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

This SAE Information Report establishes a minimum level of uniform recipes for contaminants which may be used when durability testing pneumatic components to obtain additional information on how a device may perform under more true-to-life operating conditions. This type of contamination testing, however, is not meant to replace the type of performance testing described in SAE J1409 and SAE J1410. Durability testing in the presence of contamination, however, will yield results more reflective of actual in-service field conditions and provide an additional evaluation of pneumatic devices. While the contaminant supply rate and other test criteria of the device being tested must be set by the device manufacturer or user, the items covered in this document will be:

This SAE Recommended Practice establishes minimum tolerance requirements for pilot operated and mechanically actuated modulating type valves, and through type valves used in the service brake control system when tested in accordance with the test procedure outlined in SAE J1859. This document applies to the nominal input-output characteristics as specified by vehicle original equipment manufacturer and labeled by the valve manufacturer as outlined in SAE J1860. The tolerance requirements will include: a Crack (opening) pressure or force. Crack pressure may be measured at the initial output pressure or as the pressure differential before output pressure exceeds 14 kPa (2 psi). Crack force may be measured at initial output pressure or before output pressure exceeds 14 kPa (2 psi). b Pressure differential (input-output)
