本文件规定了液化、溶解或压缩气体钢瓶上使用的阀门保护帽和阀门防护罩的要求。 阀门保护帽和阀门防护罩是可用于保护钢瓶阀门的一些选项，包括运输过程中带有整体式压力调节器（VIPRs）的阀门。 本文件适用于本质上为钢瓶阀门提供主要保护的阀门保护帽和阀门防护罩。它还可用于测试连接到气瓶包装上的其他设备（例如，搬运设备），即使在气瓶阀门本身能够承受损坏而不释放内容物的情况下也是如此。交叉引用:ISO 13341ISO 10286ISO 10297:2014ISO 17871购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document 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 equipment (e.g., handling devices) attached to cylinder packages, even in cases where the cylinder valve is inherently able to withstand damage without release of the content.Cross References:ISO 13341ISO 10286ISO 10297:2014ISO 17871All current amendments available at time of purchase are included with the purchase of this document.
