Liming materials - Determination of neutralizing value - Titrimetric methods
This European Standard specifies two methods for the determination of the neutralizing value (NV) of liming materials.
Method A is applicable for liming materials except silicate liming materials and liming materials with more than 3 % P2O5.
Method B is applicable for all liming materials except those with more than 3 % P2O5.
NOTE The methods described in ISO 6598 and ISO 7497 can be used for the determination of P2O5 content.
Calcium-/Magnesium-Bodenverbesserungsmittel - Bestimmung des Neutralisationswertes - Titrimetrische Verfahren
Diese Europäische Norm legt zwei Verfahren zur Bestimmung des Neutralisationswertes (NV) von Calcium-/Mag
nesium-Bodenverbesserungsmitteln fest.
Verfahren A gilt für Calcium-/Magnesium-Bodenverbesserungsmittel mit Ausnahme von Kalken aus Eisenhüttenschlacke und Calcium-/Magnesium-Bodenverbesserungsmitteln mit über 3 % P2O5 (Massenanteil).
Verfahren B gilt für alle Calcium-/Magnesium-Bodenverbesserungsmittel mit Ausnahme solcher mit über 3 % P2O5 (Massenanteil).
ANMERKUNG Zur Bestimmung des P2O5 -Gehalts können die in ISO 6598 und ISO 7497 beschriebenen Verfahren verwendet werden.
Amendements minéraux basiques - Détermination de la valeur neutralisation - Méthodes par titrimétrie
La présente Norme européenne spécifie deux méthodes pour la détermination de la valeur neutralisante (VN) des amendements minéraux basiques.
La méthode A est applicable aux amendements minéraux basiques, à l'exception des amendements minéraux basiques sidérurgiques et des amendements basiques contenant plus de 3 % de P2O5.
La méthode B est applicable à tous les amendements minéraux basiques à l'exception de ceux contenant plus de 3 % de P2O5.
NOTE Les méthodes ISO 6598 et ISO 7497 peuvent être utilisées pour la détermination de la teneur en P2O5.
