Denne udgivelse rummer et forslag til en standardiseret metode til test af materialers krybning, og en tilhørende teoretisk og empirisk begrebsramme som kan anvendes til at beskrive krybningen for granulerede løsfyldsmaterialer udsat for klimaets påværkninger. Desuden vises resultater fra en round-robin test. Test method and round-robin test This report presents a proposal for a standardised method for creep tests and the necessary theoretical and empirical framework that can be used to describe creep of a granulated loose-fill material exposed to climate. Furthermore results from a round-robin test are shown. The round-robin test was carried out in collaboration with Norwegian Building Research Institute department of Materials and Structures in Trondheim, SP-Swedish National Testing and Research Institute department of Energy Technology, Building Physics, Ete in Borås, VTT-Technical Research Centre of Finland department of Building and Transport in Espoo and the Danish Building Research Institute department of Building Design and Technology. For the round-robin test a cellulosic fibre insulation material was used. The proposed standardised method for creep tests and theoretical and empirical framework are limited to cases when the granulated loose-fill material is exposed to a climate that is characterised as cyclic humidity conditions (a constant temperature and a relative humidity alternating between two predetermined constant relative humidity levels). A better understanding of the behaviour of granulated loose-fill material is provided and a standardised method is proposed. This enables control of the settling and prediction of densities necessary to prevent settling. The Nordtest, Organisation for Testing in Scandinavia funded the Nordtest Projekt 1623-03.
