1 Scope This European Standard specifies the requirements for factory made products of expanded cork, which are used for the thermal insulation of buildings. The products are made with granulated cork agglomerated without additional binders and are delivered as boards without facings. This European Standard specifies product characteristics and includes procedures for testing, evaluation of conformity, marking, labelling and packaging. Products covered by this European Standard are also used in prefabricated thermal insulation systems and composite panels; the performance of systems incorporating these products is not covered. This European Standard does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards. Products with a declared thermal resistance lower than 0,25 m2⋅K/W, at 10 °C, or a declared thermal conductivity greater than 0,060 W/(m⋅K), at 10 °C, are not covered by this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

Determination of the declared values of thermal resistance and
thermal conductivity A.1 General It is the responsibility of the manufacturer to determine the declared values of thermal resistance and thermal conductivity. He will have to demonstrate conformity of the product to its declared values. The declared values of thermal resistance and thermal conductivity of a product are the expected values of these properties during an economically reasonable working life under normal conditions, assessed through measured data at reference conditions. A.2 Input data In order to calculate the declared values, the manufacturer shall have at least ten test results for thermal resistance or thermal conductivity, obtained from internal or external direct measurements. These measurements shall be carried out, at regular intervals, spread over a period of the last twelve months. If less than ten test results are available, that period may be extended until ten results are obtained but in a maximum period of three years, within which the product and production conditions have not changed significantly. For new products, the ten thermal resistance or thermal conductivity test results shall be obtained spread over a minimum period of ten days. The declared values shall be calculated according to the method given in A.3 and shall be recalculated at intervals not exceeding three months of production. A.3 Declared values A.3.1 General The derivation of the declared values RD and λD from the calculated values R90/90 and λ90/90 shall use the rules given in 4.2.1 which include the rounding conditions. A.3.2 Case where both thermal resistance and thermal conductivity are declared The declared values RD and λD shall be derived from the calculated values R90/90 and λ90/90 which are determined using the equations A.1, A.2 and A.3. λ90/90 = λmean + k × sλ (A.1) 1)(12meani−−=∑=nsniλλλ (A.2) R90/90 = dN/λ90/90 (A.3) SIST EN 13170:2009
