(Main)Fertilizers - Determination of molybdenum in concentrations > 10 % using a gravimetric method with 8-hydroxyquinoline
Fertilizers - Determination of molybdenum in concentrations > 10 % using a gravimetric method with 8-hydroxyquinoline
This Technical Specification specifies the procedure for determination of total and water extractable molybdenum in mineral fertilizers containing more than 10 % molybdenum. This method is applicable to water and aqua regia fertilizer extracts obtained according to EN 260172 and/or EN 260176.
Düngemittel - Bestimmung von Molybdän in Konzentrationen > 10 % durch Gravimetrie mit 8-Hydroxychinolin
Diese Technische Spezifikation legt ein Verfahren zur Bestimmung von Gesamt-Molybdän und wasserextrahierbarem Molybdän in mineralischen Düngemitteln, die mehr als 10 % Molybdän enthalten, fest.
Dieses Verfahren ist auf Wasser- und Königswasser-Extrakte von Düngemitteln anwendbar, die nach prEN 16962:2016 und/oder prEN 16964:2016 erhalten wurden.
Engrais - Dosage du molybdène dans des concentrations > 10 % en utilisant une méthode gravimétrique à la 8-hydroxyquinoléine
La présente Spécification technique spécifie une méthode pour le dosage du molybdène total et du molybdène extractible à l’eau dans des engrais minéraux contenant plus de 10 % de molybdène.
Cette méthode est applicable aux extraits d’engrais aqueux et à l’eau régale obtenus conformément au prEN 16962:2016 et/ou au prEN 16964:2016.
Gnojila - Določevanje molibdena v koncentracijah do 10 % z gravimetrično metodo z 8-hidroksikinolinom
Ta tehnična specifikacija določa postopek za določevanje skupne vsebnosti molibdena in molibdena, ki ga je mogoče ekstrahirati z vodo, v mineralnih gnojilih, ki vsebujejo več kot 10 % molibdena. Ta metoda se uporablja za ekstrakte gnojil v vodi in zlatotopki, pridobljene v skladu s standardom EN 260172 in/ali EN 260176.

This Technical Specification (CEN/TS) was approved by CEN on 3 March 2017 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, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
