Light Fastness Tester For Testing Lab Workshop.
Light Fastness Tester - For Testing Lab
Light Fastness Tester is used to test the colorfastness of the
material. For most materials, colorfastness against artificial light is
an important property that determines their suitability for many
specific end uses. This characteristic is determined by exposing test
specimens taken from the sample under test to a controlled intensity of
artificial light under a specified humidity and temperature to obtain a
specified degree of exposure. The actual degree of exposure is assessed
with the help of colorfastness rating standards (blue standards), which
are exposed along with the test specimens.
Colorfastness rating is determined with the help of grey scale for change in color.
