This Standard specifies the requirements for valve protection caps and valve guards used on cylinders for liquefied, dissolved or compressed gases. Valve protection caps and valve guards are some of the options available to protect cylinder valves, including valves with integral pressure regulators (VIPRs) during transport. This document is applicable to valve protection caps and valve guards which inherently provide the primary protection of a cylinder valve. It can also be used to test other e...view more
