Troubleshoot/What Is IP NEMA IK Ratings
What is IP, NEMA, and IK Ratings?
IP Rating
IP rating consists of 2 numbers, which is a standard for ingress protection. Dahua products are usually IP67.
- The IP66K is rated at higher Pressure of 1000 kPa at distance of 3 m, 10 times more thank IP66
- The IP69K test specification was initially developed for road vehicles, especially those that need regular intensive cleaning (dump trucks, cement mixers, etc.). German standard DIN 40050-9 extends the IEC 60529 rating system described above with an IP69K rating for high-pressure, high-temperature wash-down applications. Such enclosures must not only be dust-tight (IP6X), but it must also be able to withstand high-pressure and steam cleaning.
NEMA Rating
NEMA rating is the same as IP except their numbers goes from 1 to 13 with R,S,X,K as variations.
