1.1 本规范涵盖了结构立缝钢屋面板系统的设计、施工和耐候性。它仅包括以下元件的性能要求:面板、隐蔽面板夹、面板/夹锚固和面板接缝密封剂。 注1: 这些系统用于低坡度和陡坡屋顶应用。它们也可与下层甲板或护套一起使用或不使用。 1.2 本规范的目的是提供结构立缝钢屋面板系统的整体性能，如 3.2.6 在其使用寿命期间，以提供天气保护，承载规定的设计载荷，并允许在屋顶表面上进行适当的访问，以便业主对设备进行定期维护。 1.3 除结构外，规范制定者还应评估本规范范围之外影响屋顶结构最终选择的其他特性。这些因素包括但不限于功能、法律、保险和经济方面的考虑。看见 附录X1 用于说明符的检查表。 1.4 本规范并不排除参考文件未涵盖的产品或系统。 1.5 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.6 本规范的文本包含提供解释性信息的注释和脚注，而非本规范的要求。 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。

1.1 This specification covers the design, construction, and weatherability of structural standing seam steel roof panel systems. It includes performance requirements for the following elements only: panels, concealed panel clips, panel/clip anchorage, and panel joint sealers. Note 1: These systems are used on both low-slope and steep-slope roof applications. They also are used with or without an underlying deck or sheathing. 1.2 The objective of this specification is to provide for the overall performance of the structural standing seam steel roof panel system as defined in 3.2.6 during its service life in order to provide weather protection, carry the specified design loads, and allow proper access over the roof surface in order to provide for periodic maintenance of equipment by the owner. 1.3 In addition to structural, the specifier shall evaluate other characteristics beyond the scope of this specification that affect the final choice of roof construction. These include, but are not limited to, functional, legal, insurance, and economic considerations. See Appendix X1 for specifier's checklist. 1.4 The specification is not intended to exclude products or systems not covered by the referenced documents. 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.6 The text of this specification contains notes and footnotes that provide explanatory information and are not requirements of this specification. 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.
