This International Standard specifies methods for exposing specimens to laboratory light sources in order to assess changes produced by such exposure.

The following types of light source are included:

  1. xenon arc lamp;
  2. enclosed carbon arc lamp;
  3. open-flame carbon arc lamp.

Of the different light sources, the xenon arc is advantageous in that it can, when correctly filtered and maintained, yield a spectrum most closely approximating to that of daylight. The carbon arc sources yield light which is considerably different from daylight and their use is decreasing. However, they have been found useful for some specific purposes and are still in considerable use in some countries; for this reason they have been included in this International Standard.

This International Standard also specifies means of determining radiation dosage.

For the method of determination of changes in properties after exposure, reference is made to ISO 4582.
