How Well Do You Know IP69K?

Many food and beverage applications demand this highest level of washdown protection.

The IP69K rating is for applications where high-pressure and high-temperature washdowns are used to sanitize equipment. The IP69K test specification was initially developed for road vehicles, especially those that need regular intensive cleaning (dump trucks, cement mixers, etc), but has been widely adopted in the food and beverage industries as a test of products to withstand sanitary washdown.

The Ingress Protection (IP) rating system is an internationally recognized scale that relates to proven protection against environmental factors such as liquids and solids. It's a part of the IEC 60529 rating system. Products rated to IP69K first must be impervious to dust, but also must be able to withstand high-pressure and steam cleaning. To be specific:

  • A spray nozzle is fed with 80°C water at 80–100 bar (~1160-1450) at a flow rate of 14–16 L/min.
  • The nozzle is held 10–15cm from the tested device at angles of 0°, 30°, 60° and 90° for 30 seconds each.
  • The device being tested sits on a turntable that rotates once every 12 seconds.

The IP69K rating is the highest protection available.
