Prepare and wash the specimen according to method A (1) in GB/T 3921-2008.Then
filter with qualitative filter paper (medium speed), to remove impurities in the residual
soap solution. Pour the filtered soap solution into a colorimetric tube with a diameter
of 25 mm. Pour the unwashed soap solution with the same temperature as the test
temperature into another colorimetric tube (diameter 25 mm) as a reference specimen.
Under D65 standard light source, with white cardboard without fluorescent brightener
as the background, place the cardboard on the grading rack, to evaluate the degree of
staining of the washing liquid according to GB/T 251.The amount of soap solution
poured into the colorimetric tube is about 50 mL. During the grading, the distance
