Annex III.1 (II.1)

IP code

Coding system is a system presenting protection level provided by a component which shields against contact with dangerous parts, penetration of solid matters or water from outside and additional information of protection.

	IP arrangement
For instance: IP 23CH	IP	2	3	C	H
Coded letters


(International protection)
First characteristic number


(from 0 to 6, or letter X)
Second characteristic number


(from 0 to 8, or letter X)
Auxiliary letter (freely selected)


(Alphabets:A, B, C, D)

Additional letter (freely selected) (Alphabets: H, M, S, W)

•If indication of characteristic numbers, these numbers can be replaced by letter “X”(or. can be replaced by letter “XX” if omitted two characteristics)

•Auxiliary and additional letters can be omitted without replacement with letters.

•If more additional letters used, alphabetical order must be applied.

• If a shielding component generated different protection levels for different arrangement, corresponding protection levels must be indicated by manufacturers in documents related to installation and arrangement.
