The shorter side of the sample shall not be less than 300 mm or a full size of the productwhichever is smaller.5.2 ConditioningConditioning of the test specimens shall be carried out for at least 6 h at (23 ± 5) C unless otherwise specifiedin the test standard. In case of dispute, the test specimens shall be stored at (23 ± 2) C and (50 ± 5) % relativehumidity for at least fourteen days prior to testing.5.3 Testing5.3.1GeneralTable 13 gives the dimensions of test specimens and the minimum number of measurements required to getone test result and any specific conditions, which are necessary.5.3.2Thermal resistance and thermal conductivityThermal resistance and thermal conductivity shall be determined in accordance with prEN 12667 or EN 12939for thick products and under the following conditions:

Page 18EN 13163:2001– at a mean temperature of (10
0,3) °C;– after conditioning in accordance with 5.2;– after preparation in accordance with the procedure in Table 13.NOTE
Thermal
resistance and the thermal conductivity may also be measured at mean temperatures other than 10 C,providing that the accuracy of the relationship between temperature and thermal properties is sufficiently well documented.Thermal resistance and thermal conductivity shall be determined directly at measured thickness. In the eventthat this is not possible, they shall be determined by measurements on other thicknesses of the productproviding that:– the product is of similar chemical and physical characteristics and is produced on the same production unit;– and it can be demonstrated in accordance with EN 12939 that the thermal conductivity does not vary morethan 2 % over the range of the thickness where the calculation is applied.Table 13 – Test methods, test specimens and conditionsDimensions in millimetresClauseTestmethodTest specimenLength and width a, bMinimum numberof measurementsto getSpecific conditionsNoTitleone

IntroductionIt is the responsibility of the manufacturer to determine the declared values of and thermal resistance andthermal conductivity. He will have to demonstrate conformity of the product to its declared values. The declaredvalues of thermal resistance and thermal conductivity and of a product are the expected values of theseproperties during an economically reasonable working life under normal conditions, assessed throughmeasured data at reference conditions.A.2
Input dataThe manufacturer shall have at least ten test results for thermal resistance or thermal conductivity, obtainedfrom internal or external direct measurements in order to calculate the declared values. The direct thermalresistance or thermal conductivity measurements shall be carried out at regular intervals spread over a period ofthe last twelve month. If less than ten test results are available, that period may be extended until ten tes
