The shorter side of the sample shall not be less than 300 mm or full size of the product whichever is smaller. 5.2 Conditioning No special conditioning of the test specimens is needed unless otherwise specified in the test standard except for the determination of initial thermal conductivity and apparent density. For the determination of initial thermal conductivity and apparent density the test specimens shall be conditioned in accordance with EN 12429 at (70 ± 2) °C, and then at (23 ± 2) °C and (50 ± 5) % relative humidity prior to testing. 5.3 Testing 5.3.1 General Table 7 gives the dimensions of the test specimens, the minimum number of test specimens required to get one test result and any specific conditions which are necessary. 5.3.2 Thermal resistance and thermal conductivity Thermal resistance and thermal conductivity shall be measured in accordance with EN 12667 or EN 12939 for thick products under the following conditions:  at a mean temperature of (10 ± 0,3) °C;  after conditioning in accordance with 5.2.

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 The manufacturer shall have at least ten test results for thermal resistance or thermal conductivity, obtained from internal or external direct measurements in order to calculate the declared values. The direct thermal resistance or thermal conductivity 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, the time period may be extended until ten test results are obtained, but with 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 carried out 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 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 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 13166:2009
