To comply with this standard, products shall meet the requirements of Subclause 4.2, and the requirements of Subclause 4.3 as appropriate. NOTE 1 Information on additional properties is given in Annex
D. One test result for a product property is the average of the measured values on the numbers of test specimens given in Table 4. 4.2 For all applications 4.2.1 Thermal resistance and thermal conductivity For flat specimens, the thermal conductivity shall be based upon measurements carried out in accordance with EN 12667 or EN 12939 for thick products. For cylindrical specimens, EN ISO 8497 shall be used as specified in Subclause 5.3.2. In both cases, the thermal conductivity values shall be determined by the manufacturer and verified in accordance with EN ISO 13787 and Annex C of this product standard. They shall be declared by the manufacturer according to measuring standards mentioned above, covering the product service temperature range. The following conditions apply: the measured values shall be expressed with three significant figures; the declared thermal conductivity curve shall be given as a limit curve, defined in EN ISO 13787; the value of the declared thermal conductivity, λD, shall be rounded upwards to the nearest 0,001 W/(m · K); the lowest reference mean test temperature required is - 170 °C. The declared equation/limit curve is the “declared reference” with three significant figures, that is to
0,000 1 W/(m.K) for λ values below 0,1 W/(m.K) and in 0,001 W/(m.K) for λ values above 0,1 W/(m.K). This shall be used as a reference for the verification of the declaration. When thermal conductivity is declared as a table derived from the equation, rounding upwards to the next 0,001 W/(m.K) has to be done for the full range of the thermal conductivity. NOTE Determinations of the declared thermal conductivity of pipe sections, following EN ISO 8497, having joints in the metering area, include the effects of these joints as defined in EN ISO 23993. 4.2.2 Dimensions and tolerances 4.2.2.1 Linear dimensions The length, l, width, b, and thickness, d, of boards shall be determined in accordance with EN 822 and EN 823. The length, l, thickness, d, and inside diameter, Di, of pipe sections, segments and prefabricated ware shall be determined in accordance with EN 13467. No test result shall deviate from the declared values by more than the tolerances given in Table 1. Products with a surface facing or natural skin shall be tested without removing them.

The deviation from linearity, L, shall not exceed 6 mm. Products with a surface facing or natural skin shall be tested without removing them. 4.2.3 Dimensional stability under specified conditions Dimensional stability under specified temperature and humidity conditions shall be determined in accordance with EN 1604; the tests, each on different sets of specimens, shall be carried out under the following test conditions: 1) (48 ± 1) h at (70 ± 2) °C and a relative humidity of (90 ± 5) %; 2) (48 ± 1) h at (- 20 ± 3) °C.

4.2.4 Reaction to fire of the product as placed on the market Reaction to fire classification of the product, as placed on the market, shall be determined in accordance with EN 13501-1, and the basic Mounting and Fixing rules given in EN 15715:2009.
NOTE This classification is compulsory and always included in the CE Marking label. EN 13501-1:2007, Table 1, is applicable to products applied to flat surfaces or to curved surfaces with a diameter greater than 300 mm. If a flat product which has a classification according to EN 13501-1:2007, Table 1, is used in a linear application, it does not require further classification. EN 13501-1:2007, Table 3, is applicable for products applied on linear objects or with a diameter below or equal 300 mm. Detailed information about the test conditions and the field of application of the classification as stated in the reaction to fire classification report shall be given in the manufacturer’s literature. 4.2.5 Durability characteristics 4.2.5.1 General The appropriate durability characteristics have been considered an
