Method for the instrumental assessment of whiteness

This part of IS0 105 specifies a method intended for quantifying the whiteness of textiles, including fluorescent materials.
The chromaticity co-ordinates x10, y10 and the Y10 tristimulus values are calculated from the spectral radiance factors of the specimen and converted into a whiteness value. If these cannot be calculated, the x, y, Y values may be used instead. The redness/greenness tint factor may also be determined.
