Textile Test Methods Colourfastness to Artificial Light: Carbon-Arc
Radiation
1.1 This method evaluates the colourfastness to light of textiles in all forms
by exposing the material to the radiation from an enclosed carbon-arc.
1.2 The method may also be used to evaluate dye stuffs that have been applied
to textiles under specified conditions and depth of shade.
1.3 Colorfastness to light is dependent upon factors such as the spectral
distribution and intensity of…
