Ingress protection class of enclosures is given in form of IP classification, a two-digit coding which is shown below. Fibox has tested our 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.
The European standard for enclosures, EN 50298, also includes IK impact test. This test is described in EN 50102. The data for impact resistant is available for each individual Fibox enclosures.
