CEN/TS 16196:2011

Fertilizers - Manganimetric determination of extracted calcium following precipitation in the form of oxalate

This Technical Specification specifies a manganimetric method for the determination of the calcium content in fertilizer extracts.
This method is applicable to EC fertilizers for which a declaration of the total and/or water-soluble calcium content is provided for in Regulation (EC) 2003/2003, Annex I [3].

Düngemittel - Manganometrische Bestimmung von Calcium nach Oxalatfällung

Diese Technische Spezifikation legt ein Verfahren zur Bestimmung des Calciumgehalts in Dünge-mittelextrakten fest. Dieses Verfahren gilt für EG-Düngemittel, für die die Verordnung (EG) Nr. 2003/2003, Anhang I [3] die Angabe des gesamten und/oder des wasserlöslichen Calciumgehalts vorschreibt.

Engrais - Dosage manganimétrique du calcium extrait après précipitation sous forme d'oxalate

La présente Spécification technique spécifie une méthode de dosage manganimétrique du calcium dans des
solutions d’extraction d’engrais.
Cette méthode est applicable aux engrais CE pour lesquels une déclaration de la teneur en calcium total et/ou
hydrosoluble est prévue dans le Règlement (CE) n° 2 003/2003, Annexe I [3].

Gnojila - Manganometrijsko določevanje ekstrahiranega kalcija po obarjanju v obliki oksalata

Ta tehnična specifikacija opredeljuje manganometrijsko metodo določevanja vsebnosti kalcija v ekstraktih gnojilih. Ta metoda se uporablja za gnojila ES, za katera je zagotovljena deklaracija o celotni vsebnosti kalcija in/ali vsebnosti v vodi topnega kalcija v Uredbi (ES) št. 2003/2003, Priloga I [3].

English Version
Fertilizers - Manganimetric determination of extracted calcium
following precipitation in the form of oxalate
Engrais - Dosage manganimétrique du calcium extrait Düngemittel - Manganometrische Bestimmung von Calcium
après précipitation sous forme d'oxalate nach Oxalatfällung
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.
