38、 See Annex ZA. 5 Test methods 5.1 Sampling Test specimens shall be taken from the same sample, with a total area of not less than one board, sufficient to cover the needed tests. 5.2 Conditioning No special conditioning of test specimens is needed unless otherwise specified in this standard. In case

39、 of dispute, conditioning of test specimens shall be stored at (23 2) C and (50 5) % relative humidity for at least 6 h prior to testing unless otherwise specified in this standard. 5.3 Testing 5.3.1 General Table 10 gives the dimensions of test specimens, the minimum number of measurements required

40、 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 determined in accordance with EN 12667 or EN 12939 for thick products and under the following conditions: at a mean temperat

41、ure of (10 0,3) C; after conditioning in accordance with 5.2; taking into account the effect of ageing according to Annex C. NOTE Thermal resistance and thermal conductivity may also be measured at mean temperatures other than 10 C, providing that the accuracy of the relationship between temperature

42、 and thermal properties is well documented. Thermal resistance and thermal conductivity shall be determined directly at the measured thickness. In the event that this is not possible, they shall be determined by measurements on other thicknesses of the product providing that: the product is of simil

43、ar chemical and physical characteristics and is produced on the same production unit; EN 14934:2007 (E) 18 and it can be demonstrated in accordance with EN 12939 that the thermal conductivity does not vary more than 2 % over the range of thicknesses where the calculation is applied.
