Straight ammonium nitrate fertilizers - Comparative study on the determination of porosity (oil retention)
This document gives the results of inter-laboratory testing to compare the accuracy and convenience of the official EC method for porosity measurement (given in Annex B) with two non-standardized alternative methods (given in Annexes C and D) already used in some participating laboratories.
Three products, with a porosity between 1 % and 7 %, have been used in the inter-laboratory trials.
Reine Ammoniumnitratdünger - Bestimmung der Porosität (Ölretention)
Engrais simples à base de nitrate d’ammonium - Étude comparative pour la détermination de la porosité (rétention d'huile)
Le présent document fournit les résultats de l’essai interlaboratoires servant à comparer la précision et la praticité de la méthode CE officielle pour la mesure de la porosité (décrite dans l’Annexe B) avec deux méthodes alternatives non normalisées (décrites dans les Annexes C et D) déjà utilisées par certains laboratoires participants.
Trois produits, ayant une porosité comprise entre 1 % et 7 %, ont été utilisés pour les essais interlaboratoires.
