ISO 22875:2017 describes a method for determining chlorine and fluorine in uranium dioxide powder and sintered pellets. It is applicable for the measurement of samples with a mass fraction of chlorine from 5 µg/g to 500 µg/g and with a mass fraction of fluorine from 2 µg/g to 500 µg/g.
Abstract
Overview
ISO 22875:2017 specifies a validated analytical method for the determination of . The standard covers sample preparation by (steam-assisted thermal decomposition at 850 °C–1 000 °C) with subsequent measurement of chloride and fluoride ions by or . It is applicable for chlorine mass fractions from and fluorine from .
