47 - A2 LIST

Specifies an alphanumeric code for classifying the degrees of protection provided by enclosures for electrical equipment rated up to 72.5 kV. It covers protection of persons against access to hazardous parts and of equipment against ingress of solid foreign objects, dust, and harmful quantities of water. Tests, access probes and object probes and other test equipment are specified. It is identical with and reproduced from IEC 529:1989.

This standard applies to the classification of degrees of protection provided by enclosures for electrical equipment with a rated voltage not exceeding 72,5 kV.
