1.1 本规范规定了绝缘乙烯基墙板的要求，这是一种具有整体泡沫塑料绝缘材料的乙烯基墙板，其中乙烯基墙板由刚性PVC化合物制成。符合本标准要求绝缘乙烯墙板的隔热值为R-2.0或更高。本标准规定的其他性能要求和试验方法包括材料性能和尺寸、翘曲、收缩、冲击强度、膨胀、外观、热变形阻力、火焰蔓延和抗风荷载。还提供了指示符合本规范的方法。 注1: 乙烯基隔热墙板由两个主要部件组成:乙烯基墙板和隔热材料。乙烯基墙板部分应符合规范要求 D3679 .规范的适用部分 D3679 包含在本规范中。 还包括仅涉及作为单独材料的隔热层，或乙烯基墙板和隔热层整体组合的附加要求。有关进一步的解释，请参阅 附录X1 . 1.2 应按照适用要求或测试方法的规定，在绝缘材料就位或拆除的情况下对绝缘乙烯墙板进行测试。 1.3 本产品中PVC再生塑料的使用应符合第节的要求‎ 4. . 1.4 按照本规范生产的绝缘乙烯基墙板应按照制造商关于待安装特定产品的安装说明进行安装。 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。 注2: 目前还没有与该标准等效的ISO。 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 establishes requirements for insulated vinyl siding, which is vinyl siding with integral foam plastic insulating material, where the vinyl siding is manufactured from rigid PVC compound. Compliance with this standard requires insulated vinyl siding to demonstrate a thermal insulation value of R-2.0 or greater. Other performance requirements and test methods addressed by this standard include materials properties and dimensions, warp, shrinkage, impact strength, expansion, appearance, thermal distortion resistance, flame spread, and windload resistance. Methods of indicating compliance with this specification are also provided. Note 1: Insulated vinyl siding is composed of two major components: the vinyl siding and the insulating material. It is intended that the vinyl siding portion comply with Specification D3679 . Applicable portions of Specification D3679 are included in this specification. Additional requirements that pertain only to the insulation as a separate material, or to the combination of vinyl siding and insulation as a whole, are also included. For further explanation, see Appendix X1 . 1.2 Insulated vinyl siding shall be tested with the insulation material in place or removed, as specified in the applicable requirement or test method. 1.3 The use of PVC recycled plastic in this product shall be in accordance with the requirements in Section ‎ 4 . 1.4 Insulated vinyl siding produced to this specification shall be installed in accordance with the manufacturer's installation instructions for the specific product to be installed. 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 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 2: There is no known ISO equivalent to this standard. 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.
