This SAE Recommended Practice establishes minimum performance requirements for 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. endurange testing; and g. structural integrity.

The document establishes uniform performance requirements for pneumatic valves designed to operate at 931 kPa (135 psi) nominal pressure in truck and bus air brake vehicles.
