IEC 60529 IP ratings
IEC 60529 IP ratings
(OP)
I am getting mixed responses regarding whether higher IP ratings automatically qualify for the lower ratings, for example is a IP68 rated device always suitable for an IP56 application?
The first figure relating to ingress of foreign objects logically seems higher is better but what about ingress of water could it be argued a jet of water with force behind it is more intrusive than immersion in water?

RE: IEC 60529 IP ratings
Most the confusion with the IP code comes from people interpreting a higher number as being 'better' than a lower number, which isn't always the case. For example IP65 is not inherently better than IP56: an IP65 enclosure has better resistance to dust, but has poorer resistance to liquid when compared to an IP56 enclosure.
