Status : Confirmed, Current   Published : November 1999



This European Standard describes criteria for the selection of the most suitable method and technique for the assessment of leak tightness by indication or measurement of a gas leakage. Annex A, normative, allows a comparison of standard test methods. Leak detection using hydrostatic tests, ultrasonic or electromagnetic methods is not included in this document. This standard can be used for equipment which can be evacuated or pressurized.
