EN 12464-2 : Light and lighting - Lighting of work places - Part 2: Outdoor work places.

This standard defines the lighting requirements for outdoor workplaces to ensure visual performance, comfort, and safety. It establishes technical criteria relating to maintained illuminance, uniformity, luminance distribution, glare, obtrusive light, colour rendering, colour temperature, flicker, stroboscopic effects, maintenance factor, sustainability, and adaptive lighting. It specifies calculation methods (grid layout, glare control, and maintenance) and verification procedures. Tables set out minimum illuminance levels, glare limits, and colour-rendering requirements for numerous applications, including traffic areas, construction sites, industrial facilities, ports, airports, and railway stations. In particular, the 2024 edition introduces environmental zone E0 and places greater emphasis on light variability, sustainability, and the temporal effects of light.
