G01M 3/00 - Definition
This main group covers:
Investigating fluid-tightness of structures, e.g. cables, tubes, pipes, welds, pipe joints, seals, valves, containers, radiators, by using, e.g. fluid or vacuum, infrasonic, sonic, or ultrasonic vibrations, light or by using electric means, e.g. by observing electric discharges.
