G01M3/34 - CPC Classification

Classification description:

Investigating fluid-tightness of structures by using fluid or vacuum by measuring rate of loss or gain of fluid, e.g. by pressure-responsive devices, by flow detectors for containers, e.g. radiators by testing the possibility of maintaining the vacuum in containers, e.g. in can-testing machines
