适用范围：The document gives the procedures to determine the thermal resistance of products at thicknesses that exceed 100 mm for guarded hot plate or heat flow meter. It supplies 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. It does not supply information either general or on the use of interpolation equations in the measurement of thick specimens. The procedures described are based on guarded hot plates or heat flow meter apparatus.#,,#
