1.1 本规范涵盖了用于轻型建筑和半结构应用的玻璃纤维增强聚酯复合墙体和天花板的分类、结构材料、工艺、物理要求和测试方法。 1.2 有关耐化学性、耐冲击性和安装实践的补充信息，请参见 附录X1 . 1.3 根据对实验室试验的相对响应，将这些复合板分类为不同等级，不应视为火灾危险分类。 1.4 本规范包含实验室易燃性试验（试验方法 E84型 和 929年 ). 在本标准中，易燃性测试用于测量和描述材料、产品或组件在受控条件下对热和火焰的反应，但其本身并不包含实际火灾条件下材料、产品和组件的火灾危险或火灾风险评估所需的所有因素。 1.5 本规范的目的是定义复合墙体和天花板内衬板的等级、等级和一般层压性能，以确保在预期应用中使用的优质产品。当买方和制造商商定变更时，本规范无意限制或限制影响性能的技术变更。 1.6 以英寸-磅单位表示的值应视为标准值。括号中给出的值仅供参考。 1.7 本规范正文引用了提供说明材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本规范的要求。 1.8 本标准并不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建立适当的安全、健康和环境实践，并确定监管限制的适用性。 注1: 没有已知的ISO等同于本标准。 1.9 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers the classification, materials of construction, workmanship, physical requirements, and methods of testing glass-fiber-reinforced polyester composite wall and ceiling panels intended for use in light construction and semi-structural applications. 1.2 Supplementary information on chemical resistance, impact resistance, and installation practice are provided in Appendix X1 . 1.3 The classification of these composite panels into classes based on relative response to a laboratory test shall not be considered a fire-hazard classification. 1.4 This specification contains laboratory flammability tests (Test Methods E84 and D1929 ). In this standard flammability tests are used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but do not by themselves incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. 1.5 The intent of this specification is to define the class, grade, and general laminate properties of the composite wall and ceiling liner panels in order to ensure a quality product which will perform in the intended application. This specification is not intended to restrict or limit technological changes affecting performance when changes are agreed upon between the purchaser and manufacturer. 1.6 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only. 1.7 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in Tables and Figures) shall not be considered as requirements of this specification. 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. Note 1: There is no known ISO equivalent to this standard. 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.
