scope:

This document specifies the necessary information and the process required for the production of the standard-condition CIE UGR table for a luminaire at spacing to height ratio (R_SH) of 1:1. The procedure makes use of the CIE basic equation and defines the standard conditions for the calculation and presentation of the standard-condition CIE UGR table. The process is set out to assist luminaire manufacturers and lighting software providers to prepare and publish the standard-condition CIE UGR table for indoor lighting luminaires.

The UGR values produced by the methodology described in this report can be used for the verification of conformity to the limiting UGR values specified in the Standard ISO 8995- 1:2002(E)/CIE S 008/E:2001 Lighting of Indoor Workplaces [2].
