1.1 本规范涵盖了对非均质聚氨酯瓷砖或平板地板的复合物和物理特性的要求，这些瓷砖或平板地面经过印刷或其他装饰，以达到图案或视觉效果，并受到透明耐磨层的保护。 1.2 本规范涵盖由粘合剂、填料和颜料组成的非均质聚氨酯瓷砖或木板地板。粘合剂应由一种或多种聚氨酯树脂、聚氨酯共聚物或其他合适或任何期望的组合组成。其他合适的聚合物树脂可以作为粘合剂的一部分加入，条件是粘合剂的聚氨酯部分在基层中大于60%。 1.3 以英寸-磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 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。 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。

1.1 This specification covers the requirements for the compound and physical characteristics of heterogeneous polyurethane tile or plank flooring that is printed or otherwise decorated to achieve a pattern or visual and protected by a clear wear layer. 1.2 This specification covers heterogeneous polyurethane tile or plank flooring that shall be composed of binder, fillers, and pigments. The binder shall consist of one or more resins of polyurethane, polyurethane copolymers or other suitable or any desirable combination. Other suitable polymeric resins may be incorporated as part of the binder, provided the polyurethane portion of the binder is greater than 60 % in the base layer. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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. 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.
