ASTM D4960 Standard Test Method for Evaluating the Color of Thermoplastic Traffic Marking Materials describes the instrumental determination of the color of thermoplastic traffic marking materials using the CIE trichromatic Color Measurement system.
意义及用途

5.1 The test method provides a standard procedure for determining the color of thermoplastic traffic sign materials. This test method can be used in conjunction with various thermoplastic pavement marking specifications to determine that the material conforms to the specifications. Manufacturers of these materials can also use the method to determine the uniformity of thermoplastic traffic marking materials between batches.

5.2 Color standards and colorimeters are slightly different. This test method is only suitable for reporting results and listing information on instrument model names and calibration standards.
