An International Scientific Journal Utilizing Hot Disk for Thermal Conductivity Research

In the field of thermal conductivity and thermal diffusivity testing, Hot Disk holds a special position, becoming synonymous with thermal conductivity testing methods. As the inventor of the Transient Plane Source (TPS) method and holder of multiple patents, Hot Disk has developed stable, fast, and accurate methods for testing thermal conductivity and thermal diffusivity. They have created the unique high thermal conductivity Slab Method and Anisotropic Method, enabling the evaluation of various parameters with unprecedented accuracy. These advancements represent cutting-edge technology that remains unrivaled even in 2024. The Hot Disk TPS international standard method ISO-22007-2 is the only newly established international standard method related to thermal conductivity in the past decade.

Since its establishment in 1995, the number of research papers using Hot Disk for thermal conductivity testing has increased significantly. As of 2022, there were over 3,600 peer-reviewed international scientific journal articles utilizing Hot Disk for thermal conductivity and diffusivity research. In 2023, this number increased by more than 1,400, surpassing 5,000 papers until now.
