Non-destructive testing - Leak testing - Bubble emission techniques
22-09-1999
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.
