Soil improvers and growing media - Determination of electrical conductivity

Edition date: 2017-08-21
In Force
Summary: Diese Europäische Norm legt ein gerätegestütztes Verfahren zur routinemäßigen Bestimmung der elek-trischen Leitfähigkeit in einem wässrigen Extrakt aus Bodenverbesserungsmitteln oder Kultursubstraten fest. Die Bestimmung wird durchgeführt, um einen Hinweis auf den Gehalt an wasserlöslichen Elektrolyten in Bodenverbesserungsmitteln oder in Kultursubstraten zu erhalten. Dieses Verfahren gilt nicht für Calcium-/Magnesium-Bodenverbesserungsmittel und vorgeformte Materialien wie Mineralwollplatten und Schaumplatten. ANMERKUNG Die Anforderungen der Norm können von den nationalen gesetzlichen Vorgaben bezüglich der Deklaration der erwähnten Produkte abweichen.

La présente Norme européenne spécifie une méthode instrumentale de détermination de routine de la conductivité électrique dans un extrait aqueux d'amendement du sol ou de support de culture. La détermination est effectuée afin d'obtenir une indication de la teneur en électrolytes solubles dans l'eau présents dans des amendements du sol ou des supports de culture. La présente méthode n’est pas applicable aux amendements calciques et/ou magnésiens basiques, ni aux matériaux préformés tels que les blocs de laine minérale et de mousse. NOTE Les exigences de la norme peuvent diverger par rapport aux législations nationales en ce qui concerne la déclaration des produits concernés.

This European Standard specifies an instrumental method for the routine determination of electrical conductivity in a water extract of a soil improver or growing medium. The determination is carried out to obtain an indication of the content of water soluble electrolytes in either soil improvers or growing media. 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.
