Emergency lighting is also regulated and is an interim norm output for exterior workplaces (on site,...). The different European norms are listed below NBN EN (2002) - Light and lighting - Basic terms and criteria for specifying lighting requirements NBN EN (10/1999) - Light and lighting - Lighting for sports facilities NBN EN (2003) ) - Light and lighting - Lighting of work places - Part 1: indoor workplaces.
