本文件提供了一种使用预充氢试样的恒载试验评估抗氢脆（即氢延迟断裂）能力的方法。通过热解吸分析（如气相色谱法、质谱法等）对样品中吸收的氢含量进行定量分析。在氢连续充电的情况下，如自由腐蚀电位下水溶液中的氢吸收、大气腐蚀环境中的氢吸收和高压氢气中的氢吸收，也简要描述了评估方法。该方法主要适用于高强钢螺栓抗氢脆性能的评定。

This document provides a method for the evaluation of the resistance to hydrogen embrittlement (i.e. hydrogen delayed fracture) using constant loading test with hydrogen pre-charged specimens. The amount of hydrogen content absorbed in the specimens is analysed quantitatively by thermal desorption analysis such as gas chromatography, mass spectrometry and so on. In the case of hydrogen continuous charging such as hydrogen absorption in aqueous solution at free corrosion potential, hydrogen absorption in atmospheric corrosion environments and hydrogen absorption in high pressure hydrogen gas, the evaluation method is also briefly described. This method is mainly applicable to the evaluation of hydrogen embrittlement resistance of high strength steel bolts.
