27、 Method A, B and D. The color fastness of a test piece is the specific grade of a blue standard cloth whose color difference between the exposed and unexposed portions is the same as grade 4 or 3 on the gray scale. Evaluate the test piece until the color difference between the exposed and unexposed
28、portions of the blue standard cloth of grade 7 corresponds to grade 4 and 3 on the gray scale. When the color difference of the test piece comes in between two specific grades of the blue standard cloth, express it by the two grades with a dash inserted (Ex. grade 3 4). If the color difference is gr
29、ade 3 or above on the gray scale, perform the test again. 5.1.2 Test according to Method C. After completing the specified exposure cycle according to the characteristic values on drawings and material specifications, evaluate the test piece as follows: 5.1.2.1 Surface (Ex: gloss, crack and blister)
30、. 5.1.2.2 Physical properties and performance (Ex: tensile strength, abrasion, hardness). 5.1.2.3 Color change: visual check according to a gray scale. 5.2 Expression of Results. The color fastness to artificial light shall be expressed by the grade according to the evaluation method in clause 8 (ch
31、aracteristic values included for tests according to method C). Record the apparatus used for the test in the test certificate or report. 6 Safety This standard may involve hazardous materials, operations, and equipment. This standard does not propose to address all the safety problems associated wit
32、h its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 7 Notes 7.1 Glossary.
