How to set the parameters of air tightness detector

Nowadays, many products have their own waterproof products with the improvement of consumer requirements. The products launched will meet the corresponding IP waterproof level. So how is the dustproof and waterproof level of these products measured? For the waterproof test of products with certain waterproof requirements, the juice sealing test is basically carried out with a direct pressure air tightness tester. For example, an air tightness and waterproof tester is used to conduct waterproof testing and air tightness testing of IP67 and IP68 series. The waterproof testing and air tightness testing of electronic products essentially use compressed air to simulate the pressure of the product at a certain depth underwater. To determine whether water will enter, can the test parameters of the waterproof test equipment of the air tightness detector be set directly?

For IP67, IP68 and other series of waterproof level waterproof testing and air tightness testing, because the shapes and styles of the products they face are different, the parameters cannot be set directly for the products. The positive pressure method air tightness detector waterproof testing equipment is generally used as a fixture for auxiliary testing. The other holes on the product to be tested except the testing hole are blocked, so as to ensure that the testing results will not be caused by parameter mold errors. No, the test time is generally set based on the size of the product to reasonably set the inflation time, balance time, detection time and exhaust time; the test pressure is set based on the corresponding technical requirements or waterproof level, and the upper limit of the allowable leakage is It is necessary to conduct repeated tests on qualified and unqualified products based on previously set parameters to find out the critical point of the air leakage value and set the leakage amount of the air tightness and waterproof tester. Next, the air tightness detection and The waterproof testing equipment uses this parameter as a standard to conduct batch waterproof testing and air tightness testing, and automatically gives judgment results.
