Defining IP Ratings and NEMA Ratings


As I was preparing to write my blog entry, I was browsing my e-mail and came across an article in the October Issue of TIA Newsletter (Totally Integrated Automation) from Automation World, concerning IP Ratings.  I found the article , very informative as it broke down the different degrees of IP ratings, as well as some similarity and differences between IP ratings and NEMA ratings.  I only wish there was some information involving IP69K. 

This article, IP Ratings – What are they and what do they mean,  is a great starting point to learn about IP Ratings, I suggest you stop by and read it. 

For more information about IP67, check out The Secret of IP67 Protection.

    IP69K isn’t standard, it’s whatever the manufacturer has decided it to be.

      The IP68 rating is non-standard, manufactures can set this value to anything beyond the IP67 rating. IP69K however has a specified test: The test specifies a spray nozzle that is fed with 80 °C water at 8–10 MPa (80–100 bar) and a flow rate of 14–16 L/min. The nozzle is held 10–15 cm from the tested device at angles of 0°, 30°, 60° and 90° for 30 s each. The test device sits on a turntable that rotates once every 12 s (5 RPM).Thanks for the input.
