However, all solids—including metals—conduct heat via vibration between adjacent atoms. Certain solids like Styrofoam have a low k value and act as insulators. This is partially due to the low k value for air that is contained within the void spaces of these materials [4].

Testing agency responsible for data collection oversight and data analysis must have a minimum of ten years company experience in thermal conductivity testing of vertical bore heat exchangers.By recording the temperature response time of the probe, the mathematical model can be obtained directly from the thermal conductivity. Features: 1. Standard: ISO 22007-2 2008. 2. Direct measurement, testing time is about 5-160s, and can be set up, to quickly and accurately measure the coefficient of thermal conductivity, saving a lot of time. 3.Thermal conductivity testing is a fundamental thermal analysis technique that quantifies a material’s ability to transfer heat. The test involves applying a known temperature gradient across a material sample and measuring the heat flow through the material. Because thermal conductivity is a product of both the intrinsic properties of the .
The ASTM C177 is the standard test for measuring a material's thermal conductivity by means of a guarded-hot-plate instrument. For a material to be classified as a thermal insulator, it must exhibit low thermal conductivity throughout this test — which, though not identical, is comparable to ISO 8302.
