Dip the test specimen in the solution for 10 s. Suspend for 15 minutes allowing the
20、 solution to drain/evaporate, then thoroughly clean with naphtha solvent. Use an untested portion of the part as the master color. Before and after staining, measure the color of each sample per SAE J1545, CIELAB color space, 10 deg observer, illuminant D65, specular included. A part that fails this test must be coated with an appropriate clear coating and retested. 5.
