EVS-EN 13041:2000/A1:2006

This European standard specifies a method for the 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 thsoe which are pre-formed and non-particulate and are of closed porosity. It is applicable to materials with particles < 25 mm and/or flexible fibres < 80 mm.
