Thermal conductivity and diffusivity are the most important thermophysical material parameters for the description of the heat transport properties of a material or component. For the precise measurement of thermophysical properties like the thermal diffusivity, the Laser Flash technique (LFA) has proven itself as a fast, versatile and precise absolute method. NETZSCH offers three LFA models, covering the entire spectrum of materials and temperatures.
The thermal conductivity as another significant thermophysical property is determined by means of heat flow meters (HFM) with the plate method for insulators, and by means of the hot-wire method (TCT) for dielectric refractories.
NETZSCH instruments fulfill the respective instrument and application standards for LFA (e.g. ASTM E1461, DIN EN 821), for HFM (e.g. ASTM C518, ISO 8301, DIN EN 12667 EN 12, JIS A 1412) and for TCT (e.g. ISO 8894, ASTM C1113, EN 993-14/15, DIN 51046).
