[...] The certified values were obtained from the gravimetric preparation of the mother solution, taking into account the mass, purity and isotopic composition of the starting materials, the mass of the mother solution, and the mass of an aliquot in each individual unit. [...] The certified masses of plutonium and uranium and the certified values of the uranium and plutonium isotope amount ratios are based on the data from the weighing certificates and the certificates of the starting materials (metals). [...] The results of the process control measurements for 235U, 238U, and 239Pu amount contents as well as the uranium and plutonium isotope amount ratios in the mother solution of IRMM-1027u were compatible with the values from the gravimetric preparation, except the four aliquots for the n(238Pu)/n(239Pu) amount ratio. [...] Moreover, the results of the process control measurements (see Section 3.3) for the uranium and plutonium isotope amount ratios agreed with the values from the gravimetric preparation, confirming the isotope mixing of the metals.
