1.1 本规范涵盖了玻璃纤维增强石膏（GRG）复合材料，其最低性能和质量适用于生产非承重、薄壁、装饰形状的GRG零件，用于室内建筑装饰。 1.2 以英寸-磅单位或国际单位制[公制]表示的数值应单独视为标准值。在文本中，国际单位显示在括号中。每个系统中规定的值应相互独立。两个系统的值不得合并。 1.3 本标准的文本引用了提供解释材料的脚注。这些脚注不应视为本标准的要求。 1.4 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 glass fiber reinforced gypsum (GRG) composites having minimum properties and quality suitable to allow the production of GRG parts for non-loading bearing, thin section, ornamental shapes for architectural embellishment of interior building construction. 1.2 The values stated in either inch-pound units or SI [metric] are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system shall be independent of the other. Values from the two systems shall not be combined. 1.3 The text of this standard references footnotes which provide explanatory material. These footnotes shall not be considered as requirements of the standard. 1.4 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.
