1.1 这些试验方法包括白色和黄色热塑性路面标线中粘合剂和盐酸（HCL）不溶性颗粒的重量分析程序。HCL不溶性颗粒可以是回射光学器件，例如玻璃珠或某些其他类型的回射光学元件，或非回射颗粒，例如硅砂，或这些材料中任意两种或多种的组合。 1.2 当存在两种或多种HCL不溶性材料的混合物时，本标准不涉及各成分的物理分离和单独定量。 相反，它要求用户目视评估HCL不溶性材料（根据本测试方法获得）并报告存在的材料类型。 1.3 本标准并不旨在解决测试方法中详述的二氧化钛或铬酸铅颜料测量（灰化后） 394年 和 第126天 . 1.4 本标准将试图解决有机颜料对粘合剂结果的干扰。 1.5 分析程序按以下顺序出现: 小节 粘合剂百分比 10 百分比反光光学或 非反光颗粒 11 1.6 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。 1.7 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。 1.8 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 这些试验方法的作用是确定特定热塑性路面标记制造的适用规范规定的热塑性道路标记成分中粘合剂和反光光学器件或非反光颗粒的百分比。灰化后的后续样品可用于随后测试二氧化钛、铬酸铅和可能的有机颜料的存在。

1.1 These test methods cover procedures for the gravimetric analysis of the binder and hydrochloric Acid (HCL) insoluble particles in white and yellow thermoplastic pavement markings. The HCL insoluble particles can be retroreflective optics, such as glass beads or some other type of retroreflective optic, or non-retroreflective particles such as silica sand, or a combination of any two or more of these materials. 1.2 This standard does not address the physical separation and the individual quantification of each component when a mixture of two or more HCL insoluble materials is present. Rather it requires the user to visually evaluate the HCL insoluble material (obtained from following this test method) and report the types of materials present. 1.3 This standard does not purport to address the titanium dioxide or lead chromate pigment measurement (after ashing) which is detailed in Test Methods D1394 and D126 . 1.4 This standard will attempt to address the interference of organic pigments with the binder results. 1.5 The analytical procedures appear in the following order: Sections Percent Binder 10 Percent Retroreflective Optics or Non-Retroreflective Particles 11 1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.7 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. 1.8 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 The function of these test methods is to define the percent of binder and retroreflective optics or non-retroreflective particles in the composition of the thermoplastic pavement marking as defined by the applicable specification for the manufacture of a specific thermoplastic pavement marking. The subsequent sample, as a result of ashing can be used to later test for the presence of titanium dioxide, lead chromate and possibly organic pigments.
