This standard covers cylinder valve design, manufacture, and use including performance requirements such asoperating temperature limits, pressure range, and flow capabilities. It also includes requirements such as materials,inlet and outlet connections, cleaning, qualification and production testing, maintenance, and reconditioning.

This standard also includes guidelines and requirements for the design, material selection, testing, andmarking of cylinder valve protective caps. Except as noted in the last paragraph of this section, this standard isintended for valves for compressed gases packaged in U.S. Department of Transportation (DOT) andTransport Canada (TC) cylinders.

This standard provides information on valve selection, valve use guidelines, and valve protection caps (seeAppendix A, Appendix B, and Section 10, respectively).
