Fertilizers - Determination of magnesium by complexometry

This European Standard specifies a method for the determination of magnesium in fertilizer extracts by complexometry.
The method is applicable to the following EC fertilizer extracts for which the determination of total magnesium and/or water-soluble magnesium is provided for according to the Regulation (EC) No 2003/2003, Annex I [3]:
- fertilizers listed in [3], Annex I: straight nitrogenous fertilizers, type 1b + 1c (calcium magnesium nitrate), type 7 (magnesium sulfonitrate), type 8 (nitrogenous fertilizers with magnesium) and straight potassic fertilizers, type 2 (enriched kainite), type 4 (potassium chloride containing magnesium), type 6 (potassium sulfate containing magnesium salt);
- fertilizers listed in [3], Annex I D relating to secondary nutrients.

Düngemittel - Komplexometrische Bestimmung von Magnesium

Diese Europäische Norm legt ein Verfahren zur Bestimmung von Magnesium in Düngemittelextrakten fest.
Das Verfahren gilt für die folgenden EG-Düngemittelextrakte, für die die Angabe des Gesamtmagnesiums und/oder des wasserlöslichen Magnesiums entsprechend der Verordnung (EG) Nr. 2003/2003, Anhang I, [3], vorgeschrieben ist:
   in [3], Anhang I, aufgeführte Düngemittel: Einnährstoff-Stickstoffdünger vom Typ 1b  1c (Calcium-Magnesiumnitrat), Typ 7 (Stickstoff-Magnesiumsulfat), Typ 8 (Stickstoffdünger mit Magnesium) und Einnährstoff-Kalidünger vom Typ 2 (angereichertes Kainit), Typ 4 (Kaliumchlorid mit Magnesium), Typ 6 (Kaliumsulfat mit Magnesium);
   in [3], Anhang I D, aufgeführte Düngemittel mit Bezug auf Sekundärnährstoffe.

Engrais - Dosage du magnésium par complexométrie

La présente norme européenne spécifie une méthode de dosage du magnésium, par complexométrie, dans les extraits d’échantillons d’engrais.
Cette méthode est applicable aux extraits d’échantillons d’engrais CE pour lesquels le dosage du magnésium total et/ou soluble eau est prévu, conformément au Règlement (CE) n° 2003/2003, Annexe I de la référence bibliographique [3] :
   engrais répertoriés dans l’Annexe I de la référence bibliographique [3] ; engrais azotés simples, type 1b + 1c (nitrate de calcium et de magnésium), type 7 (sulfonitrate de magnésium), type 8 (engrais azotés contenant du magnésium) et engrais potassiques simples, type 2 (kaïnite enrichie), type 4 (chlorure de potassium contenant du magnésium), type 6 (sulfate de potassium contenant du sel de magnésium) ;
   engrais répertoriés dans l’Annexe I D de la référence bibliographique [3] relative aux éléments nutritifs secondaires.

Gnojila - Kompleksometrijsko določevanje magnezija

Ta evropski standard določa metodo za določevanje magnezija v ekstraktih gnojil s kompleksometrijo. Metoda se uporablja za naslednje ekstrakte gnojil ES, za katere je predvideno določanje količine skupnega magnezija in/ali v vodi topnega magnezija v skladu s Prilogo I k Uredbi (ES) št. 2003/2003: – gnojila, uvrščena na seznam v Prilogi I: enostavna dušična gnojila vrste 1b + 1c (kalcij-magnezijev nitrat), vrste 7 (magnezijev sulfonitrat), vrste 8 (dušična gnojila z magnezijem) in enostavna kalijeva gnojila vrste 2 (obogateni kajnit), vrste 4 (kalijev klorid, ki vsebuje magnezij), vrste 6 (kalijev sulfat, ki vsebuje magnezijevo sol); – gnojila, uvrščena na seznam v Prilogi I D v zvezi s sekundarnimi hranili.
