本欧洲标准描述了通过气泡发射技术检测和定位泄漏的程序。灵敏度取决于所使用的技术和材料。描述了两种技术:a）浸没技术:可以使用特定装置的程序进行定量测量（参见附录A）; b）液体应用技术。本标准可用于可抽真空或加压的设备

This European Standard describes procedures for the detection and location of leaks by the bubble emission techniques. The sensitivity depends on techniques and materials used. Two techniques are described: a) immersion technique: quantitative measurements can be made using this procedure with particular devices (see informative annex A); b) liquid application technique. This standard can be used for equipment which can be evacuated or pressurised.
