1.1 结构密封剂嵌装玻璃（以下简称SSG）是一种应用，其中密封剂不仅可以起到阻挡空气和水通过建筑围护结构的屏障的作用，而且还主要提供结构支撑，并将嵌装玻璃或其他部件连接到窗户、幕墙或其他框架系统上。 1.2 本指南为设计专业人员、制造商、承包商和其他人提供了设计和安装SSG系统的有用信息。 当用于与垂直方向不超过15°的建筑墙壁时，此信息仅适用于此嵌装玻璃方法；然而，包括关于倾斜SSG应用的有限信息。 1.3 只有专门配制、测试和销售用于结构密封胶玻璃的有机硅化学固化密封胶才可用于SSG系统应用。 1.4 对本标准具有管辖权的委员会不知道其他组织发布的任何类似标准。 1.5 以国际单位制表示的数值应视为标准。国际单位制后括号中给出的值仅供参考，不被视为标准值。本指南中的国际单位制单位符合IEEE/ASTM SI 10。 1.6 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。 1.7 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====== 5.1 “一条链只有最薄弱的环节才能强大”这句老话非常适用于SSG系统。事实上，一个SSG系统要想取得成功，就必须建立并保持一个粘合链。 例如，工厂应用的饰面必须充分粘附到金属框架构件上，结构玻璃密封胶必须粘附到该金属饰面上，该结构玻璃密封胶粘附到玻璃石上的反射涂层上，最后，该反射涂层粘附到玻璃表面上。本指南将有助于识别和制定性能标准、试验方法和行业实践，这些标准、试验和实践应用于获得所需的结构玻璃密封胶附着力和与其他系统部件的兼容性。 5.2 尽管本指南旨在方便访问感兴趣的特定区域，但强烈建议在确定特定SSG系统的要求之前阅读并理解整个指南。 5.3 本指南不应是设计和安装SSG系统所依据的唯一标准。本文提供的信息是为了帮助开发特定程序，以实现成功的SSG系统安装。 为SSG系统及其许多不同组件的评估、设计、安装和维护提供了信息和指南。考虑到结构玻璃硅酮密封胶的性能范围，以及许多类型的框架系统设计、可使用的材料组合、各种材料饰面以及许多类型和品种的附件，本文所包含的信息本质上是通用的。 5.4 一般来说，SSG系统的设计、制造和安装需要比传统玻璃窗或幕墙系统更多的技术知识和经验。 为了确保SSG系统的成功，材料和组件的供应商、制造商和安装商必须对SSG系统要求有充分的了解，并参与每种应用的设计和规划。密封剂、框架饰面、玻璃材料和部件以及各种配件的供应商应审查并同意制定的SSG系统计划、要求和质量控制计划。 5.5 至少在SSG系统开发的设计、测试、制造和安装阶段，如果没有规划和实施质量控制程序，可能会导致不理想的结果，包括令人讨厌的空气或水泄漏，或可能危及公众生命安全的灾难性故障 ( 1 , 2 ) . 8

1.1 Structural sealant glazing, hereinafter referred to as SSG, is an application where a sealant not only can function as a barrier against the passage of air and water through a building envelope, but also primarily provides structural support and attachment of glazing or other components to a window, curtain wall, or other framing system. 1.2 This guide provides information useful to design professionals, manufacturers, contractors, and others for the design and installation of a SSG system. This information is applicable only to this glazing method when used for a building wall that is not more than 15° from vertical; however, limited information is included concerning a sloped SSG application. 1.3 Only a silicone chemically curing sealant specifically formulated, tested, and marketed for structural sealant glazing is acceptable for a SSG system application. 1.4 The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations. 1.5 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. SI units in this guide are in conformance with IEEE/ASTM SI 10. 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. 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 ====== 5.1 The old saying “A chain is only as strong as its weakest link” is very applicable to a SSG system. In reality, a SSG system, to be successful, must establish and maintain a chain of adhesion. For example, a factory applied finish must adhere adequately to a metal framing member, a structural glazing sealant to that metal finish, that structural glazing sealant to a reflective coating on a glass lite, and lastly, that reflective coating to a glass surface. This guide will assist in the identification and development of, among others, performance criteria, test methods, and industry practices that should be implemented to obtain the required structural glazing sealant adhesion and compatibility with other system components. 5.2 Although this guide has been arranged to permit easy access to specific areas of interest, it is highly recommended that the entire guide is read and understood before establishing the requirements for a particular SSG system. 5.3 This guide should not be the only criteria upon which the design and installation of a SSG system is based. The information herein is provided to assist in the development of a specific program with a goal of achieving a successful SSG system installation. Information and guidelines are provided for the evaluation, design, installation, and maintenance of a SSG system and many of its various components. Considering the range of properties of structural glazing silicone sealants, as well as the many types of framing system designs, material combinations that can be used, various material finishes, and the many types and varieties of accessories, the information contained herein is general in nature. 5.4 Generally, the design, fabrication, and installation of a SSG system requires more technical knowledge and experience then is required for a conventionally glazed window or curtain wall system. To ensure the success of a SSG system, it is important that suppliers, fabricators, and installers of materials and components have a sound knowledge of SSG system requirements and become involved in the design and planning for each application. Suppliers of, among others, sealants, framing finishes, glazing materials and components, and various accessories should review and agree with the developed SSG system plans, requirements, and quality control program. 5.5 The results of not planning for and implementing quality control programs during at least the design, testing, fabrication, and installation phases of a SSG system's development can result in less than desirable results, which can include nuisance air or water leakage or catastrophic failure where life safety of the public can be at risk ( 1 , 2 ) . 8
