Representation method
The protection level is usually expressed by IP followed by two numbers, which are used to define the protection level。
The first figure indicates the range of dust resistance of the equipment, or the degree to which people are protected from harm in a sealed environment. It represents the level of preventing solid foreign matters from entering, and the highest level is 6;
The second digit indicates the degree of water resistance of the equipment. It represents the level of preventing water ingress, the highest level is 8
The waterproof test includes the second characteristic number 1 to 8, that is, the protection grade code is IPX1 to IPX8。
The first digit after IP is dust proof grade (as shown in the figure)：
Dust proof level of the second digit after IP (as shown in the figure)：
Grade waterproof test methods include：
Vertical drip test | Inclined 15 ° drip test | Water sprinkling test | Water splash test |
Water spray test | Strong water spray test | Short time immersion test | Continuous diving test |
The standards for IP (INGRESS PROTECTION) PROTECTION grade and waterproof test are:
1)International standards for protection and waterproofing tests drafted by IEC (International Electrotechnical Commission): IEC 529 – 598
2)GB 700 – 86
3)GB/T 4208-2017 Degrees of Protection Provided by Enclosures (IP Code), etc.
Our company has cooperation with SGS-CSTC testing laboratory, environmental reliability and electromagnetic compatibility testing center, aerospace environmental reliability testing and testing center, Suzhou Electric Appliance Research Institute, National Electrical Product Quality Supervision and Inspection Center, etc.
