1.1本试验方法涵盖了通过气泡发射技术检测或定位泄漏或两者的程序。定量测量是不现实的。本试验方法的正常灵敏度极限为4.5 X 10 -10 摩尔/秒（1 X 10 -5 标准cm /s） 。 1.2描述了两种技术: 1.2.1浸渍技术，以及 1.2.2液体应用技术。 注:更多信息见ASME锅炉及压力容器规范第五节第10条泄漏测试和指南E479。 1.3本标准无意解决与其使用相关的安全问题（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。

1.1 This test method covers procedures for detecting or locating leaks, or both, by bubble emission techniques. A quantitative measure is not practical. The normal limit of sensitivity for this test method is 4.5 X 10 -10 mol/s (1 X 10 -5 Std cm /s). 1.2 Two techniques are described: 1.2.1 Immersion technique, and 1.2.2 Liquid application technique. Note-Additional information is available in ASME Boiler and Pressure Vessel Code, Section V, Article 10-Leak Testing, and Guide E479. 1.3 This standard does not purport to address 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.
