本文件描述了一种测定低温泄漏保护（CSP）系统对低温液体释放产生的蒸汽阻力的方法，其中液体含量几乎为零。适用于安装在碳钢上的CSP系统。 本文件中提供的试验不适用于液化后立即在制冷回路和LNG流中发现的高压低温液体释放。

This document describes a method for determining the resistance of Cryogenic Spill Protection (CSP) systems to vapour generated from a cryogenic liquid release where the liquid content is practically zero. It is applicable where CSP systems are installed on carbon steel. The test provided in this document is not applicable to high pressure cryogenic liquid releases that can be found in refrigeration circuits and in LNG streams immediately post-liquefaction.
