With the continuous development of science and technology, various electronic products and equipment are becoming more and more popular, and the requirements for waterproof and dustproof performance of products are getting higher and higher. In this context, the IP protection level standard came into being, which has become an important basis for measuring the waterproof and dustproof ability of products. Among them, IP68 has received widespread attention as a high-level waterproof and dustproof standard. So, what is the IP68 air tightness test standard? This article will introduce it to you in detail.
IP68 is an ingress protection class** in the International Protection Marking, which indicates that the product is completely dustproof and can be immersed in water for long periods of time. Specifically, IP68 means that the product can withstand a maximum water pressure of 15 meters of water for a duration of up to 30 minutes and complete protection against dust. To ensure that products meet this standard, manufacturers need to conduct rigorous air tightness testing.
IP68 air tightness test mainly includes the following aspects:
Waterproof test: First, the product needs to be subjected to a hydrostatic test to ensure that it does not leak under the specified water pressure. For testing, the product is placed in water at a certain depth and the water pressure is gradually increased until 15 meters. During this process, the product should be kept intact and free of leakage. In addition, it is also necessary to conduct waterproof tests on the interfaces, buttons and other parts of the product to ensure that they have good sealing performance.
Dust test: After passing the waterproof test, the product needs to be tested for dust resistance. During the test, the product is placed in a dusty environment to simulate the harsh conditions of real-world use. After a certain period of testing, there should be no dust accumulation inside the product, and all parts should work normally.
Air tightness test: The air tightness test is mainly to ensure that there will be no gas leakage when the product is used under high-pressure water. To test, immerse the product in water, apply 15 meters of water depth pressure and observe if there are bubbles generated within a certain period of time. If there are no bubbles, it means that the product has good air tightness.
Withstand voltage test: After passing the air tightness test, the product needs to undergo the withstand voltage test. When testing, place the product at 1At a depth of 5 meters, it lasts for 30 minutes. During this process, the product should be kept intact and free of leakage.
In summary, IP68 airtightness testing is a rigorous process designed to ensure that the product is completely dustproof and can be immersed in water for long periods of time. Only products that pass these tests can be certified with IP68 protection. For consumers, purchasing products with IP68 certification can effectively improve the durability and reliability of products and meet the needs of different scenarios. For manufacturers, following the IP68 airtightness test standard can help improve product quality, enhance brand image, and win market share.
