current location：Xinsifang is equipped with perfect IP grade, American standard water spray and rain proof test equipment, and a team of senior certified testing engineers in the industry can provide dust-proof and waterproof grade test for the majority of lighting manufacturers.
IP grade test is mainly used to assess the reliability of the shell protection of various electrical product shells and seals under various harsh environmental conditions such as dust, humidity, drenching or diving, so as to verify whether the working performance of products and components will be damaged. At the same time, it also provides corresponding protection requirements for human body to prevent contact with dangerous parts.
IP code: indicates the degree of protection of the enclosure. The protection level is divided into many categories. According to different numbers, the protection level of products can be determined quickly and conveniently.

1. Prevent solid particles with a diameter of 50mm or more from being completely penetrated by the tip of the object or solid particles with a diameter of 50mm
2. Prevent the tip of solid particles with a diameter of 12.5mm or more or solid particles with a diameter of 12.5mm from being completely penetrated
3 prevent the tip of solid particles with a diameter of 2.5mm or more or solid particles with a diameter of 2.5mm from penetrating at all
4. Prevent solid particles with a diameter of 1mm or more from penetrating the tip of the object or solid particles with a diameter of 1mm
5 dust protection: it can not completely prevent dust from entering, but it will not hinder the normal operation of the instrument and reduce the safety
6 dust confinement: the dust cannot enter the object, and the whole diameter cannot exceed the gap of the shell

1 anti vertical falling water drops vertical falling water drops will not cause harmful effects
2 when the shell is tilted up to 15 °, the water drops that prevent vertical falling will not cause harmful effects when the shell is tilted up at any angle of no more than 15 ° on either side of the vertical
3 the waterproof fog will not cause harmful effects when spray at any angle not exceeding 60 ° on any vertical side
4. Splashing water against the shell from any direction will not cause harmful effects
5. The water sprayed from any direction against the shell will not cause harmful effects
6 prevent strong water spray. Strong water spray from any direction against the shell will not cause harmful effects
7. Prevent short-time immersion. Under normal temperature and pressure, when the shell is temporarily immersed in 1m deep water, it will not cause harmful effects
8. Continuous immersion prevention is agreed by the manufacturer and users, but under conditions more severe than 7, continuous immersion in water will not cause harmful effects
