Page 18EN 13164:2001Annex A (normative)Determination of the declared values of thermal resistance and thermalconductivityA.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 values of thermal resistance and thermal conductivity of a product are the expected values ofthese properties during an economically reasonable working life under normal conditions, assessed throughmeasured data at reference conditions.A.2Input dataThe manufacturer shall have at least ten test results for thermal resistance and thermal conductivity, obtainedfrom internal or external direct measurements in order to calculate the declared values in accordance withannex C. The direct thermal resistance and thermal conductivity measurements shall be carried out at regularintervals, spread over a time period of the last twelve months. If less than ten test results are available theperiod may be extended until ten test results are obtained, but with a maximum period of three years, withinwhich 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 overa minimum period of ten days.The declared values shall be calculated according to the method given in A.3 and shall be recalculated at aperiode not exceeding three months of production.A.3Declared 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 are determinedusing the equation A.1, A.2 and A.3.sk

Not all Euroclasses may apply for the products conforming to this standard.a
The minimum testing frequencies, expressed in test results, shall be understood as the minimum for a product or product group for each productionunit/line under stable conditions. In addition to the testing frequencies given above, testing of relevant properties of the product shall be repeated whenchanges or modifications are made that are likely to affect the conformity of the product.b
Direct testing may be conducted either by third party or by the manufacturer.c
Indirect testing may be either on the product or on its components.d
Definition as given in the Euroclasses Decision 2000/147/EC: Substantial component: A material that constitutes a significant part of a non-homogeneous product. A layer with a mass per unit area
1,0 kg/m2or a thickness
1,0 mm is considered to be a substantial component. Non-substantial component: A material that does not constitute a significant part of a non-homogeneous product. A layer with a mass per unit area < 1,0 kg/m2 and a thickness < 1,0 mm is considered to be a non-substantial component.e
In case of certified component, the frequency is once per delivery of the component.f
European Decision 96/603EC : Materials to be considered as reaction to fire class A provided for in Decision 94/611/EC without the need for testing (ofreaction to fire characteristics).g
Only for unfaced products.h
Indirect testing is only possible in the case of products falling within the system 1 for attestation of conformity of reaction to fire, or by having a notifiedbody verifying the correlation to the direct testing.

The ageingprocedure which represents a time average value of about 25 years of use, shall
be used for XPS products withand
without diffusion tight laminates with thicknesses from 20 mm to 200 mm.XPS Products that are produced with CO2 technology are not covered by
this annex C.These products shall be measured at the full thickness without laminates, 90 days after production and afterconditioning at (23
2) °C, and (50
5) % relative humidity.C.2 Procedure for XPS foam without diffusion tight laminatesC.2.1
PrincipleThe procedure involves slicing of the test specimen to increase the rate of gas exchange and thus simulates along period of use.C.2.2Sample preparationPrepare the test specimen from product of not less than 1 day and not more than 90 days old.Cut each test specimen into slices of (10
