1.1 本指南涵盖了评估和制备涂层用非聚集体表面膜的程序。它不涉及与屋顶组件或屋顶膜有关的设计、施工或安装问题。它不是屋顶涂料的应用指南。 1.2 以国际单位制或英磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不完全相等；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标准。 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》中确立的国际公认标准化原则制定的。 =====意义和用途====== 3.1 本指南概述了评估和制备用于液体表面涂层的屋顶膜所需的一般程序。 3.2 本指南并非包罗万象；本指南旨在补充制造商的详细说明和法律要求的安全要求。

1.1 This guide covers the procedures for evaluating and preparing non-aggregate surfaced membranes for the application of a coating. It does not address design, construction, or installation issues regarding the roof assembly or the roof membrane. It is not an application guide for roof coatings. 1.2 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 nonconformance with the standard. 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 ====== 3.1 This guide outlines the general procedures necessary to evaluate and prepare a roof membrane for the application of a liquid surface coating. 3.2 This guide is not all inclusive; this guide is intended to supplement detailed instructions from manufacturers and safety requirements required by law.
