标准摘要
[中文适用范围]： 本文件描述了在使用红外 (IR) 相机观察高发射率漫射表面时测量现有建筑物上不透明建筑元件的热阻和热透射率的红外方法。 本文件演示了通过定量评估来识别建筑构件热性能缺陷区域的筛选测试。 本文件旨在测量具有轻热质量的框架结构住宅的热透射率（U 值），通常根据 ISO 13786 计算的日热容量低于 30 kJ/(m2K)。 [外文原描述]： This document describes the infrared method for measuring the thermal resistance and thermal transmittance of opaque building elements on existing buildings when observing high emissivity diffuse surface using an infrared (IR) camera. This document demonstrates a screening test by quantitative evaluation to identify the thermal performance defect area of building elements. This document aims to measure the thermal transmittance (U-value) of a frame structure dwelling with light thermal mass, typically with a daily thermal capacity calculated according to ISO 13786 below 30 kJ/(m2K).
