1.1 本规程涵盖了热塑性路面标记材料试样的正确制备，以确保测试结果能够代表所测试的材料。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 本规程为热塑性路面标线材料试样的制备提供了一个标准程序，该试样应在测试规范中要求的各种性能之前进行。使用本标准方法制备的试样产生的试验结果与取样材料一致。试样的试验结果可用于确定热塑性路面标线材料是否符合规范。这些材料的制造商也可使用该规程制备试样，以测试热塑性路面标记材料的批次均匀性。 5.2 本规程并未解决任何与热塑性路面标记材料的物理或化学特性的特定测试相关的问题。

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. ====== Significance And Use ====== 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.
