Soil improvers and growing media - Determination of electrical conductivity
This European standard specifies an instrumental method for the routine determination of electrical conductivity in a water extract of a soll improver or growing medium. The determination is carried out to obtain an indication of the content of water soluble electrolytes in either soll improvers or growing media.
NOTE 1 The method is not applicable to Urning materials or sewage sludges and is not suitabte for materials like rockwool and foam slabs.
NOTE 2 The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.
Diese Europäische Norm legt ein instrumentelles Verfahren zur routinemäßigen Bestimmung der elektrischen Leitfähigkeit in einem wäßrigen Extrakt aus Bodenverbesserungsmitteln oder Kultursubstraten fest. Die Bestimmung wird durchgeführt, um eine Angabe zum Gehalt an wasserlöslichen Elektrolyten entweder in Bodenverbesserungsmitteln oder in Kultursubstraten zu erhalten.
