Abstract: The invention concerns a method of determining variations in the properties of a sample (10), in particular consisting of a polymer material, which is exposed to artificial weathering. Radiation with a spectral distribution which corresponds in terms of spectral range to that of solar radiation acts on the sample. According to the invention, in order to attain high acceleration factors without bringing about undesired heating of the sample, the sample is irradiated in a spectral range corresponding to solar radiation at an irradiation intensity which is at least approximately five times greater than that of solar radiation in the corresponding spectral range. The variations in the properties of the sample during the action of the radiation are measured.

Abstract: The invention relates to a method and device for obtaining stearin from animal or vegetable fats. The invention aims to provide a method according to which the separation efficiency between the oil and the stearin phase can be kept constant for the duration of a production period so as to achieve optimal stearin quality and yield. According to said method, crystallized oil having a temperature of between 10 DEG C and 40  DEG C is introduced into the inlet (12) of a non-selfunloading nozzle centrifuge (11) fitted with a stack of plates (15) and an immobile grasping element (16) for the oil phase. The solid phase is guided through flow spaces which narrow towards the nozzles (20) and discharged through said nozzles. To achieve a high separation efficiency between the stearin phase and the oil phase the ratio of flow input to nozzle output is set at between 2:1 and 4:1. Said method is used for obtaining stearin from animal or vegetable fats.
