scope:

To enable people to perform visual tasks efficiently and accurately, especially during the night, adequate and appropriate lighting has to be provided. The degree of visibility and comfort required in a wide range of outdoor work places is governed by the type and duration of activity.

This Standard specifies the lighting requirements related to the amount and quality of lighting which will contribute to the visual needs for safety, easiness, efficiency and comfort for performing tasks within outdoor work places or other areas related thereto.

This Standard does not provide explanation on how the lighting systems should be designed to a resolve a specific problem, nor does it restrict the freedom of designers to adopt a new technology, or use of new equipment or device.

NOTE 1 For methods of designing the lighting systems and technologies to optimize a specific visual environment, related Guides and Reports of the International Commission on Illumination (Commision Internationale de l'Eclairage, hereafter referred to as CIE) and standards issued by the Illuminating Engineering Institute of Japan should be referred to.

NOTE 2 The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows:

CIE S 015: 2005 Lighting of outdoor work places

ISO/CIE 8995-3: 2006 Lighting of work places-Part 3: Lighting requirements for safety and security of outdoor work places

(Overall evaluation: MOD)

The symbols which denote the degree of correspondence in the contents in the corresponding International Standard and JIS are IDT (identical), MOD (modified) and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
