IEC 60529 Degrees of protection provided by enclosures (IP Code)

The second characteristic numeral indicates the degree of protection provided by enclosures with respect to harmful effects on the equipment due to the ingress of water.
The tests for the second characteristic numeral are carried out with fresh water. The actual protection may not be satisfactory if cleaning operations with high pressure and temperature water jet outside the requirements of second characteristic numeral 9 and/or solvents are used.
Table 3 gives brief descriptions and definitions of the protection for the degrees represented by the second characteristic numeral.
Degrees of protection listed in this table shall be specified only by the second characteristic numeral and not by reference to the brief description or definition.
The tests are specified in clause 14.
Up to and including second characteristic numeral 6, the designation implies compliance also with the requirements for all lower characteristic numerals.
