Textiles. Tests for colour fastness. Part A03 : grey scale for assessing staining.
Dans la série des normes qui concerne les méthodes d'essais de solidité des teintures et impressions, la présente norme NF G 07-010-3 permet, au moyen d'une échelle de gris, l'évaluation des dégorgements provoqués sur les tissus témoins par les essais de solidité.
This document describes the grey scale for determining staining of adjacent fabrics in colour fastness tests, and its use. A precise colorimetric specification of the scale is given as a permanent record against which newly prepared working standards and standards that may have changed can be compared.
