ISO 15651:2015 describes a procedure for measuring the total hydrogen content of UO2 and PuO2 powders (up to 2 000 �g/g oxide) and of U02 and (U,Gd)O2 and (U,Pu)O2 pellets (up to 10 �g/g oxide). The total hydrogen content results from adsorbed water, water of crystallization, hydro-carbon, and other hydrogenated compounds which can exist as impurities in the fuel.
