Title (German)

Bodenverbesserungsmittel und Kultursubstrate - Bestimmung des Gehaltes an organischer Substanz und Asche; Deutsche Fassung EN 13039:2011

Overview

This European Standard specifies a routine method for determining the organic matter and the ash content of soil improvers and growing media. This method is not applicable to liming materials and pre-formed materials like rockwool and foam slabs. The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned. The test portion is dried at 103 °C, then ashed at 450 °C. The ash is determined as the residue on ignition. The organic matter is taken to be the loss of mass on ignition. Both are expressed as a percentage by mass of the dried sample. With respect to DIN 13039:2000-02, note 1 no longer excludes the application of the standard to sewage sludges and the relative standard deviations of the results of the interlaboratory trial given in Table A.1 were corrected. The standard was also editorially revised and therewith adopted to the current design rules. The Committee responsible for this standard is NA 057-03-01 AA "Bodenverbesserungsmittel und Kultursubstrate" ("Soil improvers and growing media") at DIN.
