IP codes
The degree of protection provided by an enclosure is indicated by IP code in following way:
IP Code
Where a characteristic numeral is not required to be specified, it shall be replaced by the letter “X” (“XX” if both numerals are omitted.)
Additional letters and /or supplementary letters may be omitted without replacement.
Where more than one supplementary letter is used, the alphabetic sequence shall apply.
If an enclosure provides different degree of protection for different intended mounting arrangements, the relevant degree of protection shall be indicated by the manufacturer in the instructions related to the respective mounting arrangements.

IP codes and their meanings:

We would like to represent it in a tabular form:
