1 Scope
This International Standard describes a procedure for measuring the total hydrogen
content of UO2 and PuO2 powders (up to 2 000 µg/g oxide) and of UO2 and (U,Gd)O2 and (U,Pu)O2 pellets (up to 10 µg/g oxide). The total hydrogen content results from adsorbed water,
water of crystallization, hydrocarbon, and other hydrogenated compounds which can
exist as impurities in the fuel.
