【国外标准】 Standard Practice for Sample Preparation of Thermoplastic Pavement Marking Materials

5.1 This practice provides a standard procedure for the preparation of thermoplastic pavement marking material test specimens prior to testing for various properties as called for in the governing specification. Specimens that are prepared using this standard methodology yield test results that are consistent with the material from which it was sampled. Test results from specimens can be used to determine compliance of the thermoplastic pavement marking material to the specification. This practice can also be used by manufacturers of these materials to prepare specimens for testing to determine the uniformity of thermoplastic pavement marking materials from batch to batch.5.2 This practice does not address any issues related to specific testing of the thermoplastic pavement marking materials for any physical or chemical property.1.1 This practice covers the proper preparation of test specimens of thermoplastic pavement marking materials obtained to ensure test results are representative of the material being tested.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
