本文件描述了一种用于测量建筑元件(例如外墙、地板、天花板(下文统称为“墙”))的绝缘性能的方法。这是通过使用探针插入方法来完成的，该方法在壁中的小直径钻孔中用温度传感器给出壁中的温度分布。测量方法分为定量方法和定性方法，定量方法使用热流测量来测量热阻，定性方法不使用热流测量。本文件描述了一种用于初步和实际诊断的筛选测试。该方法适用于热容量较小的平面建筑构件，如框架结构住宅中的构件。测量结果给出了局部测量点的绝缘性能，而不是包括热桥（如螺柱）在内的整个面板的绝缘性能。

This document describes a method for measuring the insulation performance of building elements, e.g. exterior walls, floors, ceilings (hereinafter referred to collectively as "walls"). This is done by using the probe insertion method, which gives the temperature distribution in the wall with a temperature sensor in a small diameter borehole in the wall.

The measurement method is divided into a quantitative method, which measures the thermal resistance with a heat flow measurement, and a qualitative method without heat flow measurement.

This document describes a screening test that is used for preliminary and practical diagnosis.

The method is applicable to plane building components with a light heat capacity, such as those in frame structure dwellings. The measured results give the insulation performance at the local measurement points rather than that of the whole panel including thermal bridges such as studs.
