Airtightness testing: why leakage is positive in negative pressure testing and when it is negative

Airtightness testing with positive and negative pressure method, negative pressure test results show positive values normal. Negative values may be caused by leakage of standard parts, environmental differences or structural differences, and require separate testing of standard parts, control of environmental conditions, and verification of structural consistency. Abnormal data is an opportunity to discover new problems.

In one article: the difference between an airtightness test and a pressurization test

This article describes the differences and applications of air tightness testing and pressurization testing. The airtightness test detects whether the product is waterproof by pressurization, while the pressurization test tests the strength of the product to withstand pressure, both of which aim to improve the reliability and safety. The purpose of both is to improve the reliability and safety of products.JCGK provides a variety of airtightness testing and pressurization test equipment, which are widely used in high-end manufacturing fields to help enterprises improve product quality.
