Page 18EN 13165:2001Annex A(normative)Determination of the declared values of thermal conductivity and thermalresistanceA.1IntroductionIt is the responsibility of the manufacturer to determine the declared values of thermal resistance and thermalconductivity. He will have to demonstrate conformity of the product to its declared values. The declared valuesof thermal resistance and thermal conductivity of a product are the expected values of these properties duringan economically reasonable working life under normal conditions, assessed through measured data atreference 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 months. If less than ten test results are available that period may be extended until ten testresults are obtained, but with a maximum period of three years, within which the product and productionconditions have not changed significantly.For new products the ten thermal resistance or thermal conductivity tests shall be carried out spread over aminimum period of ten days.The declared value shall be calculated according to the method given in A.3 and shall be recalculated atintervals not exceeding three months of production.A.3 Declared valuesThe derivation of the declared values, RD and D, from the calculated values, R90/90 and 90/90, shall use the rulesgiven in 4.2.1, which include the rounding conditions.A.3.1 Case where thermal resistance and thermal conductivity are declaredThe declared values, RD and D, shall be derived from the calculated values, R90/90 and 90/90, which aredetermined using equations A.1, A.2 and A.3.90/90 = mean + k

Page 23EN 13165:2001Annex C(normative)Determination of the aged values of thermal resistance and thermalconductivityC.1GeneralThis annex describes methods which are used to take account of the ageing effect, which when it occurs is dueto changes in the cell gas composition with time. These methods give a prediction of the ‘time averaged’ aged valueover 25 years.The determination of the aged value shall be made either by the direct measurement method (acceleratedageing procedure, C.4) or by a combination of the normality test and the calculation method (fixed incrementprocedure, C.5). For both methods the sampling and test specimen preparation procedure shall be as describedin C.2.NOTE
See Figure C.1 for a flow chart of the alternative ageing procedures.The ageing methods are valid for closed cell PUR products produced by using high molecular weight blowingagents such as hydro chlorofluorocarbons (e.g. HCFC 141b), hydro fluorocarbons(e.g. HFC 134a) and hydrocarbons (e.g. pentanes), which substantially stay in the products for time periods wellin excess of those required for an economically reasonable life. These blowing agents are therefore called‘permanent‘. They can be used mixed together with carbon dioxide (CO2). CO2 is a ‘non-permanent‘ blowingagent, which may readily diffuse out of the product. Ageing of the thermal properties of PUR products istherefore predominantly caused by the inward diffusion of air into the product and outward diffusion of CO2, ifdiffusion tight facings do not prevent both.PUR products blown only with CO2 are also covered by these ageing methods.If new blowing agents are shown to be ‘permanent types‘ (meaning having diffusion coefficients similar to theestablished values for pentane, hydro chlorofluorocarbons and hydro fluorocar
