BS EN 13041:2000 Soil improvers and growing media - Determination of physical properties - Dry bulk density, air volume, water volume, shrinkage value and total pore space
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 have closed porosity. It is applicable to materials with particles ≤ 25 mm and/or flexible fibres ≤ 80 mm.
NOTE 1 The method is not applicable to liming materials or sewage sludges and is not suitable for materials like rockwool and foam slabs.
NOTE 2 The method is not applicable to inorganic materials.
NOTE 3 The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.
