IP Reference Chart No liability can be accepted for the data below which is given for guidance only
In the latest standards SFS - EN 60529 4 1992 concerning the IP degrees of enclosure protection of electrical equipment there are some changes particularly with regard to the testing and identification of protection against liquids. Up to the degree 6 the protection is understood to also cover the lower protection degrees. In degrees higher than 6, each degree is to be tested separately and marked accordingly, e.g. IP67 / IP66
Room containing bath / shower
Areas of the bathroom are split into zones. As a guide only, the requirements for luminaires in each zone may be summarised as follows. Particular care should be taken with wash basins - guidance for these is also contained within BS 7671.
