Përmirësuesit e tokës dhe mjedisit prodhues - Përcaktimi i vetive fizike - Masa specifike në gjendje të thatë, vëllimit të ajrit, vëllimit të ujit, vlerës së tkurrjes dhe vëllimit të përgjithshëm të poreve

Soil improvers and growing media - Determination of physical properties - Dry bulk density, air volume, water volume, shrinkage value and total pore space

Scope

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.
This method is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs.
NOTE The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.
