With the rapid development of the automotive industry, the safety of cars has always been a key concern for car manufacturers and consumers. Due to the complex usage environment of automobiles, it is normal for consumers to travel in windy and rainy weather. Therefore, many components of automobiles need to have waterproof performance, such as automobile motors, controllers, headlights, as well as charging guns and wiring harnesses on new energy vehicles

Normally, according to the waterproof standards of the automotive industry, the waterproof level of automotive parts should reach IP66 orIP67 .So what does this waterproof level represent.IP refers to the level of protection and security. IP stands for Ingress Protection Rating (or International Protection Code), which defines an interface\'s ability to protect against liquid and solid particles. IP67 means that, without damaging the casing, 6 indicates that the accessory is not susceptible to dust intrusion, and 7 indicates that the accessory can provide internal parts with a protection time of no less than 30 minutes when immersed in water no deeper than 1m.

If the components of the car cannot reach the corresponding waterproof level, the internal parts are prone to damage during use, which poses a hidden danger to our driving safety.

From the establishment of Hai Rui Si Technology to becoming a model in the industry, air tightness testing of automotive parts has always been our focus. From initially testing automotive sockets, car lights, car wiring harnesses to testing automotive motors and cylinders, our testing cases and experience are the most abundant and diverse among peers. With the promotion of new energy vehicles by the country, Hai Rui Si Technology has become increasingly mature in the airtightness testing technology of new energy vehicle charging guns and battery packs. BYD, the earliest electric vehicle in China, is also our partner.

In terms of air tightness testing of automotive parts, stability and accuracy have always been of great concern to customers. The Hai Rui Si air tightness tester uses imported Honeywell pressure regulators, and the testing accuracy can reach 1pa. This accuracy is recognized by national patents. The stability of the Hai Rui Si air tightness tester is well-known, and each instrument undergoes comprehensive testing and an eight hour aging test before leaving the factory.
