Description	The thermal conductivity of electrolytic iron has been measured in the temperature range from 100 to 390 K on a commercial device Thermal Transport Option of a Physical Properties Measurement System produced by the Quantum Design company. The thermal conductivity showed higher values than those cited by NIST’s “Report of Investigation” for SRM 8420. The maximum deviation reached 30% at 390 K. Detailed analyses revealed that the large differences resulted from radiative losses of the interior parts of the device. The determination of the radiative losses takes into account the sample geometry, contacts, and cooling part of the device, and these differences in the thermal conductivity values were substantially reduced after accounting for these losses.

Tepelná vodivost se ukázala vyšší než jsou hodnoty uvedené v %22NIST’s Report of Investigation%22 pro SRM 8420. Maximální odchylka při 390 K byla 30%. Detailní analýza odhalila, že tato odchylka je způsobena radiačními ztrátami vnitřních částí zařízení. Stanovení radiačních ztrát zahrnuje geometrii vzorku, kontakty a chladicí část zařízení. Odchylky měřené tepelné vodivosti byly značně redukovány uvažováním těchto ztrát. (cs)
