Defining IP Ratings and NEMA Ratings

Share

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.

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

      Hello,

      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.
