Degree of protection (IP-classes)
Luminaires are given an IP-classification. The IP-classification consists of a two digit code that describes the degree of protection against solid objects as well as moisture and water. Standard luminaires will have an IP classification of IP 20 or higher.
The table below describes respective IP-classifications. The IP-class is stated in plain text on the luminaire’s label. Symbols as set out below can also be used in combination with the text. Note that IP 20 luminaires do not need to be marked. IP is an abbreviation of Ingress Protection.
