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.
