IP Rating

EN 60529 describes an international classification system for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies and moisture. This classification system utilises the letters IP followed by two or three digits.

The first number refers to the protection against solid objects and the second against liquids. The higher the number the better the protection; see below for a summary.

IP Protection Number Summary

1 Protected against solid objects up to 50mm eg accidental touch by hands
2 Protected against solid objects up to 12mm eg fingers
3 Protected against solid objects up to 2.5mm (tools and wires)
4 Protected against solid objects up to 1mm (small tools and wires)
5 Protected against dust, limited ingress (no harmful deposit)
6 Totally protected against dust

6 Protected against low pressure jets of water (use on shipdeck)- limited ingress permitted 7  Protected against the effect of immersion between 15cm and 1m

Note that there is a third number which is commonly omitted which refers to protection against mechanical impacts.

Good day I am so happy I found your weblog,

on Yahoo for something else, Regardless I am here now and would just like to say thank you for a marvelous post and a all round exciting blog (I also love the theme/design),
I don’t have time to look over it all at the moment but I
have book-marked it and also added in your RSS feeds, so when I have
time I will be back to read more, Please do keep up the superb work.

When someone writes an paragraph he/she maintains the plan of a
user in his/her brain that how a user can know it.
Thus that's why this post is great. Thanks!
