\n \"\"<\/strong>Thermal shock probe method<\/p>\n

The hot wire technique is the standard transient method for measuring the thermal conductivity of insulating materials.<\/p>\n

Device consisting of a thermal shock probe, to be placed between two specimens of the material to be characterized (symmetrical setup), an electronic data acquisition unit and graphical interface software to control tests and process results.\"\"<\/p>\n

<\/h4>\n

Principle<\/h4>\n

The principle of the thermal shock probe is to produce a localized low heating of the material (a few degrees above ambient temperature) and to measure this temperature rise over time (duration of a few minutes).<\/p>\n

Through mathematical processing of this signal integrated in the supplied software, the thermal conductivity is identified.<\/p>\n

This probe and device principle was developed by CSTB (Centre Scientifique et Technique du B\u00e2timent).<\/p>\n

It also derives from standard ASTM D5930-97 and recommendation RILEM AAC 11-3.<\/p>\n

        Measurement method<\/h4>\n

        Most of the thermophysical characterization methods we develop are based on the use of thermal shock probes. They enable creation of a thermal excitation of the material; the response to this excitation depends on the thermal properties we are seeking.<\/p>\n

        The advantages of these methods are the speed of measurements and a certain flexibility regarding specimen size.<\/p>\n

        Depending on the specificities of the materials to be characterized or the thermal properties to be determined, simply connect the selected probe to the FP2C power supply and use the associated software. Hot Wire Method<\/strong> The hot wire method enables estimation of the thermal<\/p>\n

        conductivity of a material from the temperature evolution measured by a thermocouple placed near a resistive wire.<\/p>\n
