This standard specifies principles and testing procedures for determining, by means of the
guarded hot plate or heat flow meter methods, the thermal resistance of test specimens having a
thermal resistance of not less than 0,5 m2·K/W
NOTE 1 The above limit is due to the effect of contact thermal resistances. An upper
limit for measurable thermal resistance depends upon a number of factors described in this
standard, but a unique figure cannot be assigned.
It applies in principle to any mean test temperature, but the equipment design in annex D is
essentially intended to operate between a minimum cooling unit temperature of -100 °C and
maximum heating unit temperature of +100 °C.
NOTE 2 Limits to the mean test temperature are only imposed by the materials used in
the apparatus construction and by ancillary equipment.
It supplies additional limits for equipment performance and test conditions.
It does not supply general equipment design procedures, equipment error analysis, equipment
performance check or the assessment of equipment accuracy.
It supplies example designs of equipment complying with the requirements set down in this
standard.
This standard does not supply general guidance and background information (e.g. the heat transfer
property to be reported, product-dependent specimen preparations, procedures requiring multiple
measurements, such as those to assess the effect of specimen non-homogeneities, those to test
specimens whose thickness exceeds the apparatus capabilities, and those to assess the relevance
of the thickness effect). Due to these limitations, this standard should be used in conjunction with
the product standard relevant to the product to be tested.
Although intended primarily for building materials, it can also be used for specimens of any
material that conforms to the requirements specified.
This standard does not cover measurements on moist products of any thermal resi (...abbreviated)
