Fertilizers - Determination of calcium and formate in calcium foliar fertilizers

This European Standard specifies a method for the determination of the content of calcium and formate in calcium foliar fertilizers in the presence of calcium chloride. This is determined and calculated by individual analytical determination of the following components:
-   Calcium (Ca2+),
-   Chloride (Cl-),
-   Formate (HCOO-).
The method is applicable to calcium foliar fertilizers with a calcium content of approximately 30 %.

Düngemittel - Bestimmung von Calcium und Formiat in Calcium-Blattdüngemitteln

Diese Europäische Norm legt ein Verfahren zur Bestimmung des in Calcium Blattdüngemitteln neben Calcium-chlorid vorhandenen Gehalts an Calcium und Formiat fest. Die Gehalte werden aus der analytischen Einzel-bestimmung der folgenden Komponenten ermittelt und berechnet:
-   Calcium (Ca2);
-   Chlorid (Cl);
-   Formiat (HCOO).
Das Verfahren ist anwendbar auf Calcium Blattdünger, deren Calciumgehalt bei etwa 30 % liegt.

Engrais - Dosage du calcium et du formiate dans les engrais calcium pour pulvérisation foliaire

La présente norme européenne spécifie une méthode permettant de déterminer la teneur en calcium et en formiate dans les engrais pour pulvérisation foliaire contenant du calcium en présence de chlorure de calcium. Cette teneur est déterminée et calculée par le biais de la détermination analytique individuelle des composants suivants :
-   Calcium (Ca2+),
-   Chlorure (Cl-),
-   Formiate (HCOO-).
Cette méthode s'applique aux engrais pour pulvérisation foliaire contenant du calcium ayant une teneur en calcium d'environ 30 %.

Gnojila - Določevanje kalcija in formiata v kalcijevih foliarnih (listnih) gnojilih

Ta evropski standard opredeljuje metodo določevanja vsebnosti kalcija in formiata v kalcijevih foliarnih (listnih) gnojilih ob prisotnosti kalcijevega klorida. Ta je določena in izračunana s posamičnim analitičnim določevanjem naslednjih komponent:  - kalcija (Ca2+), - klorida (Cl-), - formiata (HCOO-). Ta metoda se uporablja za kalcijeva foliarna (listna) gnojila z približno 30 % vsebnostjo kalcija.

EN ISO 3696:1995, Water for analytical laboratory use — Specification and test methods (ISO 3696:1987) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 12944-1:1999 and EN 12944-2:1999 apply. 4 Principle 4.1 General Three different analytical procedures are used for the determination of the components to be determined, calcium, formate and chloride, in calcium foliar fertilizers. The substances calcium formate and calcium chloride are calculated stoichiometrically from the analytical results determined in each case (4.2, 4.3 and 4.4) (see Clause 9). 4.2 Calcium The calcium content is determined complexometrically with the diluted sample in strongly alkaline solution by means of adjusted 0,1 mol/l EDTA solution (5.1) and the calcium-specific indicator, calconcarboxylic acid (8.2).
4.4 Chloride The chloride content is determined by potentiometric titration according to the following reaction (see 8.4); the sample is first diluted, acetone is added and then the sample is acidified with acetic acid: Cl- + Ag+: AgCl (solid) After each addition of AgNO3 the measured potentials are measured and recorded using a titroprocessor. The endpoint is reached when the differential quotient E/∆V, i. e. the potential change E observed for each volume step ∆V, reaches its greatest value. This point can be determined using a titroprocessor or voltmeter. In this titration the chloride ions which are determined include other water-soluble halogen ions apart from fluorides. The total halogen content is designated chloride content. See EN 480-10 for the principles. 5 Reagents Use only reagents of recognized analytical grade and distilled or demineralized water (grade 3 according to EN ISO 3696:1995). 5.1 EDTA solution, (ethylenedinitrilotetraacetic acid disodiumsalt dehydrate), c(EDTA) = 0,1mol/l.
