The Industry Standard for the Manometric Method of Leakage Testing

One of the tasks of automatic leakage control is the assessment of the reliability of measurement results. It has become necessary to create a standard-setting document that would reflect the requirements to methods and means of leakage monitoring, their metrological checks, control systems and devices for test volume formation. In this article the industry standard for non-destructive testing is studied, which represents a normative document for assessing the quality of the assembling process. The methods and unified control facilities of leakage testing of mass-produced and serial products are described. The authors present the scheme of a sensor that compensates for the errors resulting from the changes in barometric pressure, temperature and volume variations of the products manufactured within tolerance limits.
