1.1 本规范 2. 涵盖了通过模塑（EPS）或挤出（XPS）可膨胀聚苯乙烯制成的带或不带饰面或涂层的多孔聚苯乙烯板的类型、物理性能和尺寸。根据本规范制造的产品适用于温度为-65至+165°F（-53.9至+73.9°C）的隔热材料。本规范不适用于使用任何类型的刚性板饰面制造的层压产品，包括纤维板、珍珠岩板、石膏板或定向刨花板。 1.1.1 第IV类和第XIII类管道、储罐和设备隔热的附加要求，适用于-320至+165°F（-196至+73。 9°C）包含在 附件A1 。 1.2 本规范所涵盖的隔热材料的使用可能受到涉及防火性能的规范的监管。对于某些最终用途，规范还需要解决防潮和抗风压的影响。关于这些最终用途注意事项的指导方针包含在 附录X1 。 1.3 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。 1.4 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。 1.5 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 2 covers the types, physical properties, and dimensions of cellular polystyrene boards with or without facings or coatings made by molding (EPS) or extrusion (XPS) of expandable polystyrene. Products manufactured to this specification are intended for use as thermal insulation for temperatures from –65 to +165°F (–53.9 to +73.9°C). This specification does not apply to laminated products manufactured with any type of rigid board facer including fiberboard, perlite board, gypsum board, or oriented strand board. 1.1.1 Additional requirements for Types IV and XIII for pipe, tank, and equipment thermal insulation for temperatures from –320 to +165°F (–196 to +73.9°C) are contained in Annex A1 . 1.2 The use of thermal insulation materials covered by this specification is potentially regulated by codes that address fire performance. For some end uses, specifiers need to also address the effect of moisture and wind pressure resistance. Guidelines regarding these end use considerations are included in Appendix X1 . 1.3 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. 1.4 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. 1.5 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.
