Air tightness test
Air tightness test
In practical applications, the tightness is the limit that allows the medium to leak if a certain pressure medium is applied to the seal to be tested. The air tightness test can determine whether the workpiece is leaking or leaking by visually measuring the amount of bubbles. It can also judge whether the workpiece is leaky by the signal of the sensor and calculate the leak rate.
As a professional performance testing mechanism, Qingdao Su test sea test can pass the bubble method, smear method, pressure change method, flow method, chemical gas tracer leak detection method, ultrasonic method, etc. according to ISO, ASTM, DIN, GB, HB and other standards. The method completes the airtight performance testing service for various products.
