标准摘要
[中文适用范围]： 本文件描述了一套使用现有标准化CEN或ISO测试和计算方法来确定反射绝缘产品热性能的程序。本文件支持但不替代现有的CEN或ISO测试方法。 本文件适用于任何热绝缘产品，其声称的热性能部分来自于一个或多个反射或低辐射表面以及任何相关的空气间隙的存在。它不替代现有程序，用于确定已由现有协调产品标准涵盖的产品的热性能，其中这些产品的声明值不特别包括任何可归因于面层辐射率的声明。它不提供也不可以提供使用或设计的热性能值，但提供了标准化的信息，从中可以确定这些值。 [外文原描述]： This document describes a set of procedures for using existing standardized CEN or ISO test and calculation methods to determine the thermal performance of reflective insulation products. This document supports and does not replace existing CEN or ISO test methods. This document applies to any thermal insulation product that derives a proportion of its claimed thermal properties from the presence of one or more reflective or low emissivity surfaces together with any associated airspace(s). It does not replace the existing procedures for the determination of the thermal performance of products already covered by an existing harmonized product standard where the declared value of these products does not specifically include any claims attributable to the emissivity of the facing. It does not, and cannot, give an in-use or design value of thermal performance, but provides standardized information from which these can be determined.
