1.1 本试验方法涵盖了当两种环氧树脂的组合受到现场可能遇到的温度变化时，用作混凝土覆盖层时，哪些环氧树脂配方会发生脱胶的测定。 1.2 单位- 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合规范。 1.3 本标准的文本是指提供解释性材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应被视为本标准的要求。 1.4 本标准并非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制定适当的安全、健康和环境实践，并确定监管限制的适用性。 第节中给出了具体的危险说明 8. 。 ( 警告 -新鲜的水硬性水泥混合物具有腐蚀性，长时间暴露可能会对暴露的皮肤和组织造成化学灼伤。） 2. 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 本试验方法适用于制造环氧树脂的材料- 混凝土路面的砂浆覆盖层。如果覆盖层和路面之间出现脱胶，则该材料不合适。 5.2 该试验方法评估了在显著温度范围内的空气中重复热循环过程中，覆盖层与混凝土基底保持粘合的能力，并且不打算重复现场的温度波动。

1.1 This test method covers the determination of which epoxy-resin formulations are subject to debonding when used as overlays for concrete when the combination of the two is subjected to temperature changes that may be met in the field. 1.2 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification. 1.3 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard. 1.4 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. A specific hazard statement is given in Section 8 . ( Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to exposed skin and tissue upon prolonged exposure.) 2 1.5 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 test method applies to materials used in making epoxy-mortar overlays for concrete pavement. If debonding occurs between the overlay and the pavement, the material is unsuitable. 5.2 This test method evaluates the ability of an overlay to remain bonded to a concrete substrate during repeated thermal cycling in air over a significant temperature range and is not intended to duplicate temperature fluctuations in the field.
