Popis

PD CEN/TR 14539:2021


This standard PD CEN/TR 14539:2021 Straight ammonium nitrate fertilizers. Comparative study on the determination of porosity (oil retention) is classified in these ICS categories:
  • 65.080 Fertilizers

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.
