Test criteria

With the thermal manikin, the effective thermal insulation is first determined and the duvet is classified into one of three thermal insulation classes. The Hohenstein Skin Model according to DIN EN ISO 11 092 is then used to measure material specific values such as thermal and water vapour resistance, water vapour absorbency and buffering capacity of water vapour. The determined values are converted into ‘sleep comfort votes’ for warm climate and cold climate with the help of an evaluation system to characterize the thermophysological properties of the duvet.
