本文件提供了一种评估高强度钢抗氢脆（即氢延迟断裂）能力的方法，该方法使用氢预充试样的慢应变速率试验。通过热解吸分析（如气相色谱法、质谱法等）对样品中吸收的氢进行定量分析。本文件包括光滑或缺口试样的试验方法。 适用于铁素体基体钢。

This document provides an evaluation method of the resistance of high-strength steels to hydrogen embrittlement (i.e. hydrogen delayed fracture) using slow strain rate test with hydrogen pre-charged specimens. The amount of hydrogen absorbed in the specimens is analysed quantitatively by thermal desorption analysis such as gas chromatography, mass spectrometry and so on. This document includes testing methods for either smooth or notched specimens. It is applicable to ferritic base steels.
