Thermal Diffusivity Testing Services

TPS (ISO 22007-2:2008)

The Hot Disk Transient Plane Source constitutes an industry benchmark Thermal Property test system. The TPS Thermal Conductivity Instrument is designed for analyzing thermal transport properties of solids, liquids, paste, and powders, including various types of geometry and dimensions. The TPS 2500 S and TPS 1500 Thermal Conductivity Systems are the only Transient Plane Source (TPS) Method to meet a testing standard (ISO/DIS 22007-2.2).

ASTM 1461

Thermal diffusivity is an important property, required for such purposes under transient heat flow conditions, such as design applications, determination of safe operating temperature, process control, and quality assurance.

The flash method is used to measure values of thermal diffusivity, α, of a wide range of solid materials. It is particularly advantageous because of simple specimen geometry, small specimen size requirements, rapidity of measurement and ease of handling
