ASTM D4960 – Standard Test Method for Evaluation of Color for Thermoplastic Pavement Marking Materials
Description:
Significance and Use
5.1 This test method provides a standard procedure for the determination of color of thermoplastic pavement marking materials. This test method can be used in conjunction with various thermoplastic pavement marking specifications to determine compliance of the material to said specification. This method can also be used by manufacturers of these materials to determine the uniformity of thermoplastic pavement marking materials from batch to batch.
5.2 There is a slight variation in color standards and colorimeters. This test method is only applicable when results are reported with information listing the instrument model designation and calibration standard.
Scope
1.1 This test method describes the instrumental determination of color of thermoplastic pavement marking materials using the CIE Y, x, y color measurement system.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
