5 Test methods 5.1 Sampling Test specimens shall be taken from the same sample which shall be at least one full board. 5.2 Conditioning For test specimens consisting of full boards, no conditioning is needed unless otherwise specified in the test standard. In case of dispute, the test specimens shall be stored at (23 ± 2) °C and (50 ± 5) % relative humidity for at least 6 weeks prior to testing. When cut from boards, except for 5.3.2, test specimens shall be stored in an atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity until stabilisation at constant weight is achieved. Stabilisation is obtained when the relative change in weight does not exceed 0,5 % between two consecutive weekly measurements. In case of dispute, the following stepwise procedure shall be carried out:  step 1 (dry reference): The specimens are stored for 72 h at (70 ± 2) °C, in an oven ventilated with an air taken at (23 ± 2) °C and (50 ± 5) % relative humidity, and then weighed. The mass of the test specimen at step 1 is m23,dry.  step 2 (normal reference): After conditioning according to step 1, the specimens are stored in an atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity until stabilisation, and then weighed. Stabilisation, by definition, takes at least 6 weeks with some additional time so that the relative change in moisture does not increase by more than 5 % between two consecutive weekly measurements. The mass of the test specimen at step 2 is m23,50. Moisture content, u23,50, expressed in kilogram per kilogram, shall be determined by weighing the specimens at each step with an accuracy of 0,1 g, and calculated using equation (1): 23,drydry2350235023mmmu,,,−= (1) SIST EN 13169:2009

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 conductivity and thermal resistance. He will have to demonstrate conformity of the product to its declared values. The declared values of thermal conductivity and thermal resistance 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 conductivity or thermal resistance, 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 time period of the last twelve months. If less than 10 test results is available, that 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 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 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 13169:2009
