NeoTIM commercialize a device for characterizing the thermal conductivity, diffusivity and thermal effusivity of insulating materials called FP2C.
This device relies on :
\u2022 the hot wire method for measuring thermal conductivity
\u2022 the hot ring method for measuring thermal diffusivity
\u2022 the hot plane method for measuring thermal effusivity<\/p><\/div><\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

This principle of probe and device was initially developed by the CSTB (Centre Scientifique et Technique du B\u00e2timent). It is also derived from ASTM D5930-97 (Standard Test Method for the Thermal Conducitivity of Plastics by Means of a Transient Line Source Technique) and RILEM AAC 11-3.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The principle of this shock probe is to produce locally a low heating of the material (a few degrees above the sample) and to measure this temperature rise over time (duration of a few minutes). By mathematical processing of this signal integrated in the supplied software, the identification of the thermal conductivity is achieved.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t
