This document specifies the requirements for valve protection caps, valve guards and shrouds used on cylinders for liquefied, dissolved or compressed gases. Valve protection caps, valve guards or shrouds are some of the options available to protect cylinder valves (including Valves with Integral Pressure Regulators, abbreviated VIPRs) during transport. While this document is applicable to valve protection caps, valve guards and shrouds which inherently provide the primary protection of a cylinder valve, it might also be beneficially used to test other equipment attached to cylinder packages, even in cases where the cylinder valve is inherently able to withstand damage without release of the content. NOTE – Small cylinders (e.g. medical) are commonly transported in an outer-packaging (e.g. pallet) to meet transport regulations. This document does not specify requirements that might be necessary to enable the valve protection device to be used for lifting the cylinder.
