Enclosure protection test, commonly referred to as IP ratings, is mainly to assess the reliability of the protection performance of various electrical product enclosures and sealing elements under various harsh environmental conditions such as dust, moisture, water spray or immersion, so as to verify whether the function of the products and components will be damaged, and provide the corresponding degree of protection requirements for the parts which is dangerous to human body .

IP is the abbreviation of INTERNATIONAL PROTECTION, which means the internationally recognized degree of protection. IP codes are generally composed of two numbers or supplementary letter: the first number refers to the degree of protection against solid objects, and the second number refers to the degree of protection against water. The larger number is, the higher degree of protection grade is.
