Also, cut two 20 x
6、 28 cm test specimens from material which is known to meet the soiling requirement of the Engineering Specification. The latter sample must be the same color and grain as the material being tested, and will be the control specimen. Retain one of each specimen. Mount one of each specimen in holder (c

Following the exposure period of the test specimens, p
8、repare a two percent soap solution. Using the soft bristle brush and the soap solution, wash one-half of each test specimen. Rinse the washed area of the two specimens with cool water and blot dry with a paper towel. 3. Compare the cleaned exposed control test specimen area with the cleaned exposed
9、area of the specimen under test. Report the ease of cleanability, relative color and/or gloss change or any change as defined in the Engineering Specification between the cleaned control specimen and the cleaned specimen tested. Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
