1.1 本规范涵盖了专门设计用作外覆层基材的外部石膏板产品的最低要求和应用方法。 1.1.1 本规范不包括专门为室内应用设计的石膏板产品。 1.2 实现所需耐火性的特定组件的施工细节应从耐火测试报告、工程评估或认可的防火测试实验室的列表中获得。 1.2.1 本规范应适用于比防火结构更严格的地方（框架的尺寸或厚度以及紧固件的尺寸和间距）。 1.3 如果石膏板产品组件需要声音控制，则施工细节应符合符合要求声学值的组件的声学测试报告。 1.3.1 本规范应适用于比额定结构更严格的地方（框架的尺寸或厚度以及紧固件的尺寸和间距）。 1.4 如果石膏板产品组件需要承受支架荷载或剪切力，则施工细节应符合符合要求支架或剪切值的组件的支架或剪切试验报告。 1.4.1 本规范应适用于比支架或剪切试验结构更严格的地方（框架的尺寸或厚度以及紧固件的尺寸和间距）。 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 本标准的文本引用了提供解释性材料的注释。这些注释不应被视为本标准的要求。 1.7 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。 1.8 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 minimum requirements for and methods of application of exterior gypsum panel products that are specifically designed for use as a substrate for exterior cladding. 1.1.1 This specification does not cover gypsum panel products that are specifically designed for interior applications. 1.2 Details of construction for a specific assembly to achieve the required fire resistance shall be obtained from reports of fire-resistance tests, engineering evaluations, or listings from recognized fire testing laboratories. 1.2.1 This specification shall govern where it is more stringent (size or thickness of framing and size and spacing of fasteners) than the fire-rated construction. 1.3 Where sound control is required for a gypsum panel product assembly, the details of construction shall be in accordance with the acoustical test report of an assembly that has met the required acoustical value(s). 1.3.1 This specification shall govern where it is more stringent (size or thickness of framing and size and spacing of fasteners) than the sound-rated construction. 1.4 Where resistance to racking loads or shear is required for a gypsum panel product assembly, the details of construction shall be in accordance with the racking or shear test report of an assembly that has met the required racking or shear value(s). 1.4.1 This specification shall govern where it is more stringent (size or thickness of framing and size and spacing of fasteners) than the racking or shear-tested construction. 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 standard references notes which provide explanatory material. These notes shall not be considered as requirements of the standard. 1.7 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. 1.8 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.
