Scope

1.1 This test method describes the instrumental determination of color of thermoplastic traffic marking materials using the CIE tristimulus 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.

This standard does not purport to address all of the safety concerns, if any, associated with 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.

Significance and Use

This test method provides a standard procedure for the determination of color of thermoplastic traffic 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 traffic marking materials from batch to batch.

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.
