From: Wanken IP waterproof level tester/tester,
IP is the abbreviation of Ingress Protection, and IP grade is the protection grade of electrical equipment shell against foreign body invasion. Its source is IEC 60529, which was also adopted as the American national standard in 2004.
In this standard, the format of IP grade for the protection against foreign objects of electrical equipment enclosures is IPXX, where XX is two Arabic numerals, the first sign number indicates contact protection and foreign object protection grade, and the second sign number indicates waterproof protection grade. Please refer to the table below for specific protection levels. Ip is an international code used to identify the protection level. The IP level consists of two numbers, the first number stands for dust prevention; The second number means waterproof, and the larger the number, the better the protection level.
Dustproof grade
Definition of digital protection degree
0 No protection, no special protection
1 Prevent the intrusion of objects larger than 50mm, prevent the human body from touching the interior of lamps by mistake, and prevent the intrusion of objects larger than 50mm in diameter.
2 Prevent objects larger than 12mm from invading and prevent fingers from touching the interior of lamps.
3 prevent all things larger than 2.5 mm from invading, and prevent tools, wires or objects larger than 2.5 mm in diameter from invading.
4 Prevent the invasion of objects larger than 1.0mm and prevent the invasion of mosquitoes, flies, insects or objects with a diameter larger than 1.0.
5 Dust prevention cannot completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal work of lamps and lanterns.
6 Dust-proof and thoroughly prevent dust from invading.
Waterproof grade
Definition of digital protection degree
0 No protection, no special protection
1 Prevent dripping intrusion and drip vertically.
2 When the lamp is tilted 15 degrees, it can still prevent dripping.
3. Prevent the intrusion of sprayed water, and prevent rain or water sprayed in the direction where the vertical included angle is less than 50 degrees.
4. Prevent splashing water from invading, and prevent splashing water from invading in all directions.
5. Prevent the invasion of big waves or water rapidly sprayed from water spray holes.
6 to prevent big waves from invading lamps. The lamps can still work normally under certain time or water pressure.
7. Prevent water from invading the lamps and lanterns from being submerged indefinitely, and ensure the lamps and lanterns to work normally under certain water pressure conditions.
8 prevent the influence of sinking
IP (International Protection) rating is based on the following criteria:
1) International protection and waterproof test standard drafted by IEC (International Electrotechnical Commission).
