1.1 本规范涵盖建筑物含铅涂料用非增强液体涂层封装产品（单层或多层涂层系统）的最低材料性能要求和实验室测试程序。本规范中涉及的性能特性包括: 1.1.1 抗冲击性， 1.1.2 粘附， 1.1.3 干耐磨性， 1.1.4 水蒸气传输， 1.1.5 耐水性和耐化学性， 1.1.6 表面燃烧特性， 1.1.7 挥发性有机化合物（VOC）含量， 1.1.8 风化作用 1.1.9 变老 1.1.10 耐擦洗性， 1.1.11 防霉性， 1.1.12 可涂漆性/可修复性， 1.1.13 灵活性，以及 1.1.14 拉伸性能。 1.2 本规范没有针对特定使用条件选择封装产品。特定使用条件可能需要本规范中规定以外的性能值。请参阅指南 E1796 . 1.3 本规范不包括在工业钢结构或住宅涂层金属表面上封装产品之前使用防腐底漆。尚未研究与铅涂料封装剂结合的直接对金属（DTM）底漆的类型。 应通过在每个特定项目中的试验应用来评估底漆的使用，以获得可接受的基底，以接收密封剂，并抑制封装基底的未来腐蚀。 1.4 本规范适用于主要依赖粘附力附着到表面的任何非增强液体应用产品。这些产品用于封装含铅油漆表面，以减少人类接触铅。 1.5 本规范中包含的测试方法的结果不一定能预测现场性能。 1.6 以国际单位制表示的数值应视为标准值。 国际单位制后括号中给出的值仅供参考，不被视为标准值。 1.7 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 1.8 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《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。

1.1 This specification covers minimum material performance requirements and laboratory test procedures for non-reinforced liquid coating encapsulation products (single or multiple-coat systems) for leaded paint in buildings. Performance properties addressed in this specification are: 1.1.1 Impact resistance, 1.1.2 Adhesion, 1.1.3 Dry abrasion resistance, 1.1.4 Water vapor transmission, 1.1.5 Water and chemical resistance, 1.1.6 Surface burning characteristics, 1.1.7 Volatile organic compound (VOC) content, 1.1.8 Weathering, 1.1.9 Aging, 1.1.10 Scrub resistance, 1.1.11 Mildew resistance, 1.1.12 Paintability/repairability, 1.1.13 Flexibility, and 1.1.14 Tensile properties. 1.2 This specification does not address the selection of an encapsulation product for specific use conditions. Specific use conditions may require performance values other than those stated in this specification. See Guide E1796 . 1.3 This specification does not cover the use of corrosion-inhibiting primers prior to encapsulation products on either industrial steel structures or on residential coated metal surfaces. Types of Direct-To-Metal (DTM) primers in conjunction with lead paint encapsulants has not been investigated. Use of primers to yield substrates acceptable to receive an encapsulant, and to inhibit future corrosion of encapsulated substrates, should be evaluated by trial applications at each specific project. 1.4 This specification applies to any non-reinforced liquid applied product that relies primarily on adhesion for attachment to the surface. These products are used to encapsulate a leaded paint surface with the intent of reducing human exposure to lead. 1.5 The results of the test methods included in this specification will not necessarily predict field performance. 1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 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.
