This European standard describes an instrumental method for the routine determination of the physical properties, dry bulk density, water volume, air volume, shrinkage value and total pore space of soil improvers or growing media. This European standard is not suitable for those materials which are very coarse, which do not make proper capillary contact or those which are pre-formed and non-particulate and are of closed porosity. It is applicable to materials with particles not less than 25 mm and/or flexible fibres not less than 80 mm.
