适用范围：This Technical Report supplements technical information on modelling of heat transfer in products of high andmedium thermal resistance when the thickness effect may be relevant; by doing this it supplies minimumbackground information on the interpolating equations to be used in the procedures described in EN 12939 to testthick products of high and medium thermal resistance.All testing procedures to evaluate the thermal performance of thick specimens require utilities, which are essentiallybased on interpolating functions containing a number of material parameters and testing conditions. Interpolatingfunctions and material parameters are not the same for all materials.Essential phenomena and common interpolating functions are presented in Clause 4, which is followed by separateequations for each material family.This Technical Report also gives diagrams derived from the above interpolating equations to assess the relevanceof the thickness effect for some insulating materials.
