Their committees work with the manufacturing and service industries, government, businesses and 122966 to facilitate the production of British, European and International standards. The luminance ralio values shalt be maintained for all illuminances between Ix and 40 Ix. The luminance, measured in cdlm2, is the light intensity per illuminated area in this case the equivalent area of each element Figure A.

These effects shall be tested by either conducting the dry bd test or the solar radiation tesl for Class T1 only.
