IP and Classifications
Ingress
protection class of enclosures is given in form of IP
classification, a two digit coding which is shown below. Gainta has
tested the enclosures according to IEC 529 or EN 60529. The latter requires the second digit to be tested from class 6 upwards separately to each level of class, thus the double marking IP 66 / IP 67 indicates that the actual tests have been made for both levels.
