1.1 本规范涵盖了建筑用玻璃纤维增强聚酯塑料板的分类、施工材料、工艺、最低物理要求和测试方法。专用或独特应用的面板可能需要大大高于或低于本规范中规定的值。某些特定应用的推荐做法包括: 附录X1 . 当买方和卖方就影响性能的技术变更达成一致意见时，本规范无意限制或限制这些变更。 1.2 有关耐化学性、耐热性和安装实践的补充信息，请参阅 附录X1 . 1.3 根据实验室试验的相对响应将这些塑料板分类为不同类型，不应视为火灾危险分类。 1.4 以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.5 本标准的文本引用了提供解释材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。 1.6 通过实验室可燃性试验（试验方法）确定火灾特性 D635 , D1929 和 E84 ). 1.6.1 本标准用于测量和描述材料、产品或组件在受控条件下对热量和火焰的响应，但其本身并不包括在实际火灾条件下对材料、产品或组件进行火灾危险或火灾风险评估所需的所有因素。 1.6.2 防火测试本身就很危险。在进行这些测试时，应采取适当的人员和财产保护措施。 1.7 以下预防性警告仅适用于试验方法部分第节 8. 符合本规范的要求。 本规范无意解决与其使用相关的所有安全问题（如有）。本规范的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 注1: 没有已知的ISO等效于本标准。 1.8 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。

1.1 This specification covers the classification, materials of construction, workmanship, minimum physical requirements, and methods of testing glass-fiber reinforced polyester plastic panels intended for use in construction. Panels for specialized or unique applications have the potential to require values significantly above or below those stated in this specification. Recommended practices for certain specific applications are included as Appendix X1 . This specification is not intended to restrict or limit technological changes affecting performance when those changes are agreed upon between the purchaser and the seller. 1.2 Supplementary information on chemical resistance, resistance to heat, and installation practices are provided in Appendix X1 . 1.3 The classification of these plastic panels into types based on relative response to a laboratory test shall not be considered a fire hazard classification. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in Tables and Figures) shall not be considered as requirements of this standard. 1.6 Fire properties are determined by using laboratory flammability tests (Test Methods D635 , D1929 , and E84 ). 1.6.1 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions. 1.6.2 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.7 The following precautionary caveat pertains only to the test method portion, Section 8 of this specification. This specification 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 specification to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 1: There is no known ISO equivalent to this standard. 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.
