Scope

This European Standard specifies a routine method for preparing a sample of soil improver or growing media prior to chemical analysis and physical testing. The procedures described herein apply only to those samples that are supplied to a laboratory in the form in which they will be used for their intended purpose.
NOTE 1 This method is not applicable to liming materials and is not suitable for materials like rockwool and foam slabs.
NOTE 2 The determination of the laboratory compacted bulk density is given in Annex A.
NOTE 3 The results of an interlaboratory trial to determine moisture content are given in Annex B.
NOTE 4 The results of an interlaboratory trial to determine compacted laboratory bulk density are given in Annex B.
NOTE 5 Attention is drawn to the possible existence of national legislation for the declaration of specific products, which could differ from the general requirements of this European Standard.
