Parts 3.0 or 3.0 color readings shall be measured in the same location on the sample before and after exposures perCIELAB color space, 10 degree observer, illuminant D65 specular included. Exposed samples may be wipedwith a solution o
36、f water and mild detergent and blotted dry with a clean white cloth before the color reading istaken.For textile covered components acceptable color change is defined as a noticeable value (lightness) and/orchroma (saturation) change with minimum hue change and/or pattern appearance change is accept
37、able. Forguidance textiles shall exhibit a Rating of 3 or greater per ISO 105-A02 grey scale.4.4.3.3 Procedure.
