Method:

Stage: 1

  • A strip of test specimen (50 × 10 mm) and one strip each of 1 to 8 light fastness standard (LFS) is mounted on the specimen card and the same type is put in the type ?A' rectangular cell. Along with double slot mask (1/3 area cover) 2/3 of the specimen is exposed to light.
  • The effect of light is followed by inspecting the specimen frequently. When a change in color of the exposed portion of the specimen can just be perceived, equal to gray scale grade 4-5, the number of the light fastness standard showing a similar change is noted.
  • The exposure of the specimen and the LFS is continued until the contrast between the exposed and the unexposed portions of the specimen or the LFS no. 7 is equal to gray scale grade 4.
  • If the LFS no.7 fades to a contrast equal to gray scale grade 4 before the specimen does, the exposure is terminated at this stage.

Stage 2:

  • If the specimen fades to a contrast equal to gray scale grade 4 before the LFS no.7  does, the double slot mask is taken out and the single slot mask is inserted having 2/3 area cover.
  • The exposure is continued until the contrast between the fully exposed and the unexposed portions of the specimen is equal to gray scale grade 3. The exposure is terminated at this stage.
  • Assessment of light fastness is done.
