1.1 本指南涵盖了硅酮密封剂在建筑施工保护玻璃系统中的应用。防护玻璃包括设计用于遭受自然灾害的应用中的系统，例如飓风、地震、风暴、风传播碎片的影响；以及入室盗窃、空中爆炸、强行进入袭击和弹道袭击等袭击。 1.2 虽然其他玻璃附件和部件用于防护玻璃，但本文件特别描述了硅酮密封剂用于防护玻璃系统的用途。 1.3 本指南为设计专业人员、建筑师、制造商、安装人员和其他人提供了有用的信息，用于设计和使用保护玻璃系统的硅酮密封剂。 1.4 硅酮密封剂只是玻璃系统的一个组成部分。满足防护玻璃的测试和规范要求的玻璃系统必须成功地将框架及其锚固件、玻璃或其他玻璃材料、保护膜或夹层以及硅酮密封剂集成到高性能系统中。符合规范或其他要求可以通过玻璃系统的物理测试或通过计算机模拟来确定。 1.5 使用硅酮密封剂的玻璃系统已成功满足导弹冲击和空气爆炸测试要求的测试要求，包括使用专门为此应用配制、测试和销售的硅酮密封剂。当今常用的密封剂符合规范 C920 和 C1184 . 1.6 本指南不讨论旨在防止放射性或提供生物密封的密封剂。1.7 对该标准有管辖权的委员会不知道其他组织发布的任何类似标准。 1.8 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 1.9 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 提供了在防护玻璃中使用硅酮密封剂的指南。防护玻璃包括指南中未涵盖的各种形式的玻璃 C1401 和 C1193 保护玻璃中密封剂的要求与结构密封剂玻璃的要求相似。然而，对于某些应用，如导弹冲击和防爆玻璃，密封剂的要求可能更高。防爆玻璃的失效模式可以不同于导弹冲击玻璃的失效模式。特别值得关注的是来自冲击波负相压力或玻璃的动态回弹或两者的出站玻璃支撑载荷。 4.2 许多类型的防护玻璃系统相对较新，防护玻璃的测试方法和标准也在不断发展。由于防护玻璃系统中对密封剂的要求正在发生变化，因此在许多情况下，指南必然是通用的。4.3 作为玻璃系统的部件，密封剂可以是玻璃系统是否满足特定测试方法要求的一个因素，但其他因素如框架和玻璃类型可能具有更大的影响。 4.4 防护玻璃系统的设计者应咨询组成材料的各种制造商。玻璃系统设计师与密封剂制造商和其他部件制造商合作的经验和判断可以最终确定特定的玻璃系统是否将成功满足特定的测试要求。

1.1 This guide covers the use of silicone sealants in protective glazing systems for building construction. Protective glazing includes systems designed for use in applications subject to natural hazards, such as hurricanes, earthquakes, windstorms, impacts from wind-borne debris; and assaults such as burglary, air blasts, forced-entry attacks and ballistic attacks. 1.2 While other glazing accessories and components are used in protective glazing, this document specifically describes the use of silicone sealants for protective glazing systems. 1.3 This guide provides information useful to design professionals, architects, manufacturers, installers, and others for the design and use of silicone sealants for protective glazing systems. 1.4 A silicone sealant is only one component of a glazing system. A glazing system that meets the testing and code requirement for protective glazing must successfully integrate the frame and its anchorage, glass, or other glazing materials, protective film or interlayer and silicone sealant into a high performance system. Compliance with code or other requirements can be determined through physical testing of the glazing system or through computer simulation. 1.5 Glazing systems using silicone sealants that have successfully met the test requirements for missile impact and airblast test requirements incorporate the use of silicone sealants specifically formulated, tested, and marketed for this application. Sealants that are commonly used today comply with Specifications C920 and C1184 . 1.6 This guide does not discuss sealants intended to protect against radioactivity or provide biological containment. 1.7 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations. 1.8 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. 1.9 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 Guidelines are provided for the use of silicone sealants in protective glazing. Protective glazing incorporates various forms of glazing that are not covered in Guides C1401 and C1193 . The requirements for a sealant in protective glazing are similar to the requirements for structural sealant glazing. However, for certain applications, such as missile impact and blast resistant glazing, sealant requirements may be greater. Modes of failure for blast resistant glazing can be different than the modes of failure for missile impact glazing. Of particular concern is the outbound glazing support loading from blast wave negative phase pressure or the dynamic rebound of the glazing, or both. 4.2 Many types of protective glazing systems are relatively new and the test methods and standards for protective glazing are continually evolving. Because the demands on a sealant in protective glazing systems are changing, guidelines are necessarily general in many instances. 4.3 As a component of a glazing system, the sealant can be a factor in whether a glazing system meets the requirements of a specific test method but other factors such as the frame and glazing type, may be of greater influence. 4.4 The designer of a protective glazing system should consult with the various manufacturers of the component materials. The experience and judgment of the glazing system designer working with the sealant manufacturer and other component manufacturers, can ultimately determine whether a specific glazing system will successfully meet a specific test requirement.
