ANNEX 6 − APPENDIX 2
METHOD OF MEASUREMENT OF THE DIFFUSION AND TRANSMISSION OF LIGHT
1. EQUIPMENT (see Figure 1 below)
The beam of a collimator K with a half divergence β/2 =17.4 × 10 rad is limited by a diaphragm

The non-transparent central part of the diaphragm is necessary in order to eliminate the light
arriving directly from the light source. It shall be possible to remove the central part of the
diaphragm from the light beam in such a manner that it returns exactly to its original position.
The distance L D and the focal length F of the lens L shall be so chosen that the image of D
completely covers the receiver R.
For L it is recommended to use a focal distance of about 80 mm.
When the initial incident flux is referred to 1 the absolute precision of each reading shall be better
