IP dust and waterproofing class defines the extent to which mechanical and electronic equipment can provide protection against solid foreign matter entry (including body parts such as fingers, dust, gravel, etc.), liquid penetration, and accidental contact.Generally with IP plus two Numbers, the first number represents the dustproof ability, the second number represents the waterproof ability, the larger the number the stronger the ability.
The traditional method is to use water to inspect the waterproofing performance of the product.This method is undoubtedly the most reliable method, but the disadvantages such as low efficiency, component contamination, subjective judgment, and inability to measure leakage value make it unsuitable for batch detection and precision detection in online production.At present electronic factory product waterproof test batch online detection, most of the use of differential air tightness leak detector (also known as waterproof tester).
Differential pressure air leak detector with compressed air as the test medium, respectively, to detect end and standard end (seal) into a certain pressure of gas, balance after a period of time, observe the detection of the pressure change, if the test workpiece is leaking, the detection of end pressure is reduced, air leak detector by differential pressure sensor to read the pressure change size, and through a series of algorithms (effectively eliminate the influence of deformation and temperature on testing results) and eventually to leakage size determination, the workpiece is qualified or not according to the decision criteria for judging.、
Compared with the detection of IP waterproofing grade, we can convert the water pressure into air pressure according to the standard requirements of IP grading.For example, the waterproof requirement of IP67 is 1 meter into the water, and the detection pressure of 10-15kpa is needed for the detection with the air tight leak detector.For the detection of higher grade IP68, the specific detection requirements need to be formulated by the manufacturer, but the detection pressure must be greater than 10-15kpa.
And we can use professional ip testing equipment to test the ip rating of the products. Naili is professional test equipment manufacturer focusing on waterproof tester and IP testing equipment. Further information, check their website https://www.zsnaili.net/.
