1.1 本指南提供了现场修复现有结构密封胶玻璃（以下简称SSG）安装的建议。当更换玻璃时，为了进行日常维护，或在发现故障后，可能需要进行补救工作。本指南侧重于大规模补救措施，而不是孤立的维修或维护。 1.2 C24委员会不知道其他组织发布的任何类似标准。 1.3 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。 ====意义和用途====== 4.1 提供了修复现有SSG装置的指南。 请参阅指南 C1401 完整讨论正确的SSG设计、安装和材料。 4.2 由于特定建筑中可能使用的材料范围不限，而且每种设计都是独特的，因此本指南中包含的信息本质上是通用的。 4.3 在设计SSG补救措施时，本指南不应是唯一参考。例如，如果已知实际使用的材料，也应考虑当地建筑规范和制造商的产品文献。密封剂制造商应全面参与补救设计。 4.4 本指南旨在作为一种资源，但不能替代所讨论的特殊类型施工补救措施设计中的经验和判断。其目的是与其他资源一起使用，以帮助解决现有SSG的问题。

1.1 This guide provides recommendations for remedying existing structural sealant glazing (hereinafter called SSG) installations in situ. Remedial work may be necessary when a lite of glass is replaced, for routine maintenance, or after distress is discovered. This guide focuses on large-scale remedies, not isolated repairs or maintenance. 1.2 Committee C24 is not aware of any comparable standards published by other organizations. 1.3 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 remedying existing SSG installations. Refer to Guide C1401 for a complete discussion of proper SSG design, installation, and materials. 4.2 Due to the unlimited range of materials that may be used in a particular building, and because each design is unique, the information contained in this guide is general in nature. 4.3 This guide should not be the only reference consulted when designing remedies for SSG. For example, the local building code and the manufacturers' product literature for the actual materials used, if known, also should be considered. The sealant manufacturer(s) should be involved fully with the remedial design. 4.4 This guide is intended to be a resource, but it is not a substitute for experience and judgement in designing remedies for the specialized types of construction discussed. It is intended to be used in conjunction with other resources as an aid in remedying problems with existing SSG.
