What is the IP protection level? IP level test standard

Date:2023-03-02 14:00:00

The IP protection grade test is to classify the product according to its characteristics of dust prevention, foreign object intrusion prevention, water resistance and moisture resistance, mainly to test whether the product has the ability of dust prevention and water resistance. The scope of IP protection grade test includes enclosure protection grade, lamp protection grade and motor protection grade. The IP protection level is composed of two numbers. The first number indicates the level of dust prevention and protection of electrical appliances from foreign objects (the foreign objects here contain things, and people's fingers should not touch the live parts of electrical appliances to avoid electric shock). The second number indicates the tightness of electrical appliances against moisture and water immersion. The larger the number, the higher the protection level. View >>
