This standard gives the procedures to determine the thermal resistance of products the thicknesses
of which exceed the maximum thickness for guarded hot plate or heat flow meter apparatus. In
any case most of the procedures described in this standard require apparatus that allows tests on
specimens up to 100 mm thick.
This standard gives guidelines to assess the relevance of the thickness effect, i.e. to establish
whether the thermal resistance of a thick product can or cannot be calculated as the sum of the
thermal resistances of slices cut from the product, these guidelines complement the indications
given in ISO 8302:1991 on the guarded hot plate apparatus.
This standard describes testing conditions which prevent the onset of convection. which could
take place in some products under the considered temperature differences and thicknesses.
