This section of Part 2 of IEC 598 specifies requirements for fixed luminaires intended for use in the water, or in contact with the water, in, for example, the basins of swimming pools, fountains, paddling pools, and garden pools.
NOTE Electrical installation rules for swimming pools are given in IEC 364-7-702: Electrical installations of buildings — Part 7: Requirements for special installations or locations — Section 702: Swimming pools.
This section does not cover luminaires not in contact with the water (e.g. mounted behind a glass panel which is separate from the luminaire) or hand-held or portable luminaires. It is to be read in conjunction with those sections of Part 1 to which reference is made.
