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.

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.
