What is BS EN 12667 - High thermal resistance building materials about?
Steady-state heat transfer properties may be measured by a number of standardized test methods: the choice of the most appropriate method depends on specimen characteristics. BS EN 12667 covers the guarded hot plate and the heat flow meter methods only.
BS EN 12667 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
Note1: BS EN 12667 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, BS EN 12667 should be used in conjunction with the product standard relevant to the product to be tested.
Note2: BS EN 12667 does not cover measurements on moist products of any thermal resistance or measurements on thick products of high and medium thermal resistance.
Who is BS EN 12667 - High thermal resistance building materials for?
BS EN 12667 on the thermal performance of building materials and products is useful for:
- Civil engineers
- Architects
- Interior designers
- Safety inspection authorities
Why should you use BS EN 12667 - High thermal resistance building materials?
BS EN 12667 provides general information on the apparatus, all mandatory limits for the equipment design and operation, and the specification of the testing procedure, for specimens, with high and medium thermal resistance, described in relevant technical specifications (e.g., a European product standard or a European technical approval).
BS EN 12667 also includes examples of equipment designs that meet the apparatus requirements, so that the assessment of the accuracy of equipment designed accordingly does not need an error analysis but only the equipment performance check.
Overall, the guidelines of BS EN 12667 enable you to perform the guarded hot-plate and heat flow-meter methods accurately and determine the thermal performance of high thermal resistance building materials.
