Information on additional properties is given in Annex E. One test result on a product property is the average of the measured values on the number of test specimens given in Table 12. SIST EN 14309:2010
EN 14309:2009 (E) 12 4.2 For all applications 4.2.1 Thermal conductivity For flat specimens, 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. They shall be declared by the manufacturer according to the measuring standards mentioned above covering the product service temperature range. The following conditions apply: the measured values shall be expressed to 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 declared equation/ limit curve is the "declared reference" with three significant figures, that is to 0,000 1 W/(m·K) for
values below 0,1 W/(m·K) and in 0,001 W/(m·K) for
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 flat products 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 for the labelled class.
