ISO 22007-6:2014 specifies a modulated temperature method realizing the measurement of thermal conductivity. An input of temperature deviation is less than 1 K, and a double lock-in method is applied to amplify the small temperature modulation.
ISO 22007-6:2014 specifies the method to determine the thermal conductivity in the range from 0,026 W/mK to 0,6 W/mK.
