适用范围：This European Standard specifies a routine method for preparing a sample of soil improver or growingmedia prior to chemical analysis and physical testing. The procedures described herein apply only tothose samples that are supplied to a laboratory in the form in which they will be used for theirintended purpose.NOTE 1 This method is not applicable to liming materials and is not suitable for materials like rockwool andfoam 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 inAnnex B.NOTE 5 Attention is drawn to the possible existence of national legislation for the declaration of specificproducts, which could differ from the general requirements of this European Standard.
