1.1 本规程涵盖了在安装弹性地板之前，单组分流体应用膜形成防潮系统在高水分混凝土基材上的性能、应用和性能。 1.2 该实践包括对混凝土表面处理的建议，以容纳单组分、流体施加的膜形成防潮系统。 1.3 本规程不取代单组分、流体应用膜形成防潮系统制造商、弹性地板制造商、衬垫制造商、粘合剂制造商或饰面地板系统的其他组件或其组合的书面说明。本规程的用户应查看制造商的技术数据表和安装说明，以了解系统组件的兼容性。 1.4 以下内容不包括在本实践的范围内: 1.4.1 防潮系统，与混凝土的任何成分发生化学反应，在混凝土内部或表面形成凝胶或结晶物质。 1.4.2 在混凝土表面不形成连续膜的渗透性水基或溶剂基化合物。 1.4.3 松散铺设的板材防潮系统。 1.4.4 剥离和粘贴防潮系统。 1.5 单位-- 以国际单位制表示的值应被视为标准。本标准不包括其他计量单位。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。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。 第节给出了一些具体的危害声明 8. 关于危险。 1.7 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====== 4.1 混凝土基材散发的水分会对弹性地板覆盖系统的性能产生不利影响。大多数弹性地板和粘合剂制造商都会公布其产品能够令人满意的最大可接受湿度水平。拟使用的单组分流体应用膜形成防潮系统的要求和其他相关细节通常作为项目计划或规范的一部分，可能与本实践中提出的最低建议有所不同。 4.2 这种做法旨在供项目设计团队使用，他们在投标和施工之前决定将水分缓解纳入项目规范和投标文件，而不要求在混凝土板浇筑后对其进行水分测试。 4.2.1 本规程旨在在确定混凝土板的水分条件超过弹性地板覆盖物或粘合剂制造商的要求，或两者兼而有之后使用，根据试验方法进行测试 1869年成立 , F2170 ，或指南 F2659 . 4.2.2 本规程适用于正常重量或结构轻质混凝土板基材表面。 4.3 单组分、流体应用的成膜防潮系统不适用于石膏基基材。

1.1 This practice covers the properties, application, and performance of a single component, fluid-applied membrane-forming moisture mitigation system to high moisture concrete substrates prior to the installation of resilient flooring. 1.2 This practice includes recommendations for the preparation of the concrete surface to receive a single component, fluid-applied membrane-forming moisture mitigation system. 1.3 This practice does not supersede written instructions of the single component, fluid-applied membrane-forming moisture mitigation system manufacturer, the resilient flooring manufacturer, underlayment manufacturer, the adhesive manufacturer, or other components of the finish flooring system, or combinations thereof. Users of this practice should review manufacturer’s technical data sheets and installation instructions for compatibility of system components. 1.4 The following are not included in the scope of this practice: 1.4.1 Moisture mitigation systems that chemically react with any constituent of the concrete to form a gel or crystalline substance within, or on the surface of, the concrete. 1.4.2 Penetrating, water- or solvent-based compounds that do not form a continuous membrane on the concrete surface. 1.4.3 Loose-laid sheet moisture mitigation systems. 1.4.4 Peel-and-stick moisture mitigation systems. 1.5 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.6 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. Some specific hazards statements are given in Section 8 on Hazards. 1.7 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 ====== 4.1 Moisture emitting from concrete substrates can detrimentally affect the performance of resilient floor covering systems. Most resilient flooring and adhesive manufacturers publish a maximum acceptable level of moisture in which their products can perform satisfactorily. Requirements for single component, fluid-applied membrane-forming moisture mitigation systems to be used, and other related details, are generally included as part of the project plans or specifications and may vary from the minimum recommendations set forth in this practice. 4.2 This practice is intended for use by project design teams who have, in advance of bidding and construction, made a decision to include moisture mitigation within the project specifications and bid documents without any requirement for moisture testing of the concrete slabs after they are placed. 4.2.1 This practice is intended for use after it has been determined that a concrete slab moisture condition exceeds the resilient floor covering or adhesive manufacturer’s requirements, or both, as tested according to Test Methods F1869 , F2170 , or Guide F2659 . 4.2.2 This practice is intended for use on normal weight or structural lightweight concrete slab substrate surfaces. 4.3 Single component, fluid-applied membrane-forming moisture mitigation systems are not intended for use over gypsum-based substrates.
