G01M3/2869 - 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 pipes, cables or tubes; for pipe joints or seals; for valves ; for welds for pipe joints or seals for seals not incorporated in a pipe joint
