We are no stranger to the environmental testing equipment industry in sand and dust test chambers. I often hear the term dustproof grade. What exactly is a dustproof grade? Each grade represents a lot of dustproof ability. Now let's make a brief introduction. IP is the abbreviation of Ingress Protection (Ingress entrance). The IP level is the level of protection against intrusion of foreign objects by electrical equipment enclosures. The sub-standard was also adopted as the US national standard in 2004. In this standard, it is aimed at the protection of foreign bodies by electrical equipment enclosures. The format of the IP rating is IPXX, XX is two Arabic numerals, the first marked number represents the protection level of contact protection and foreign objects, and the second marked number represents the waterproof protection level. For the specific protection level, please refer to the table below. P is the international code used to determine the protection level. The Ip level is composed of two numbers, the first number is dustproof; the second number is waterproof, and the larger the number, the better the protection. Dust-proof level 0-no protection without special protection 1-prevent the intrusion of objects larger than 50 mm to prevent the human body from accidentally touching the internal parts of the lamp to prevent the intrusion of objects larger than 50 mm in diameter 2-prevent the intrusion of objects larger than 12 mm to prevent the fingers from touching To the internal parts of the lamp 3-prevent the intrusion of objects larger than 2.5mm to prevent the intrusion of tools, wires or objects with a diameter greater than 2.5mm 4-prevent the invasion of objects larger than 1.0mm prevent the intrusion of mosquitoes, insects or objects larger than 1.0 in diameter 5 --Dustproof cannot completely prevent dust intrusion, but the amount of intrusive dust will not affect the normal operation of the lamp 6 --Dustproof completely prevents dust intrusion When you choose a sand and dust test box, you can choose the appropriate protection level according to the product needs to be tested The equipment tests and evaluates the performance of the product.
