Fertilizers - Determination of magnesium by complexometry
This Technical Specification specifies a method for the determination of magnesium in fertilizer extracts.
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 Technische Spezifikation 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 Spécification technique spécifie une méthode de dosage du magnésium 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 référen ce
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 tehnična specifikacija opredeljuje metodo določevanja magnezija v ekstraktih gnojil. Metoda se uporablja za naslednje ekstrakte gnojil ES, za katere je zagotovljeno določevanje celotne vsebnosti magnezija in/ali vsebnosti v vodi topnega magnezija, v skladu z Uredbo (ES) št. 2003/2003, Priloga I: gnojila, navedena v dodatku I: enostavna dušikova gnojila, tip 1b + 1c (kalcijev magnezijev nitrat), tip 7 (magnezijev sulfonitrat), tip 8 (dušikova gnojila z magnezijem) in enostavna kalijeva gnojila, tip 2 (obogateni kainit), tip 4 (kalijev klorid, ki vsebuje magnezij), tip 6 (kalijev sulfat, ki vsebuje magnezijevo sol); gnojila, navedena v dodatku I D, ki se nanaša na sekundarna hranila.

This Technical Specification (CEN/TS) was approved by CEN on 5 March 2011 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
