1.1本试验方法适用于测定浓度为0.05 mg/kg至1 mg/kg的铝和铝合金中的氢。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 5.1本试验方法旨在对铝和铝合金进行常规试验，以定性测定铝和铝合金中的氢浓度。由于缺乏经认证的参考材料，因此不打算验证是否符合成分规范。假设所有使用该测试方法的人都是经过培训的分析员，能够熟练、安全地执行常见的实验室程序。 预计这项工作将在配备适当的实验室中进行。

1.1 This test method applies to the determination of hydrogen in aluminum and aluminum alloys in concentrations from 0.05 mg/kg to 1 mg/kg. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 5.1 This test method is intended for the routine testing of aluminum and aluminum alloys to qualitatively determine the concentration of hydrogen in aluminum and aluminum alloys. It is not intended to verify compliance with compositional specifications because of the lack of certified reference materials. It is assumed that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory.
