标准摘要
[中文适用范围]： 本文件描述了一种确定低温泄漏防护系统 (CSP) 对低温泄漏的耐久性的方法。 它适用于 CSP 系统安装在碳钢上并与低温液体接触的情况。 液氮被用作低温介质，因为它的沸点比液态天然气或液氧低。 此外，它可以安全地用于实验。 该标准的未来部分将解决气相和暴露于高压喷雾条件的问题。 测试实验室负责根据当地法规进行适当的风险评估，以测试暴露于液氮和气态氮对设备和人员的影响。 [外文原描述]： ISO 20088-1:2016 describes a method for determining the resistance to liquid cryogenic spillage on cryogenic spillage protection (CSP) systems. It is applicable where CSP systems are installed on carbon steel and will be in contact with cryogenic fluids. Liquid nitrogen is used as the cryogenic medium since it has a lower boiling point than liquid natural gas or liquid oxygen and it is not flammable. Additionally, it can be safely used for experiment. Future parts of the standard will cover vapour phase and jet exposure conditions. The test laboratory is responsible to conduct an appropriate risk assessment according to local regulation in order to consider the impact of liquid and gaseous nitrogen exposure to equipment and personnel.
