That’s a loaded question…but we deliberately wrote it that way to alert you to a critical consideration: watertightness is not a binary concept. It’s not a simple yes or no. There are other factors at play – such as force/pressure and whether the enclosure must survive immersion.

This is why the IP ratings scale is not as simple as it appears at first glance. Whilst higher numbers may suggest superior levels of protection, there’s much more to it than that. Here are some examples…

Diecast aluminum enclosures such as premium aluCASE and new aluDOOR offer different levels of protection. For instance, they are both rated to:

  • IP 66 – complete protection against dust ingress, protection against temporary flooding (such as in heavy seas) – the test involves the enclosures withstanding 100 litres of water per minute at a pressure of 100 kPa at a distance of three metres.
  • IP 67 – complete protection against dust ingress; protection against immersion in water (150-1,000 mm deep) for at least 30 minutes.
  • IP 69K – complete protection against dust ingress; protection from high-pressure water jets and steam cleaning.
