Description
Fine fly ash (ca. 60 kg) originating from the 3rd zone of electrofilters at Kozienice power station, Poland (over 93% of the material passed through the 0.06 mm sieve); was homogenized by mixing in a plastic drum. After preliminary homogeneity testing (XRF) the material was distributed in 50 g portions into PE bottles and final homogeneity test (Fisher¡¦s test) was performed by instrumental neutron activation analysis. Comparison of determined content of Co, Cr, Fe, La, Sc and Th obtained in two series of measurements confirmed good homogeneity of the material for samples weigh of m >100 mg. All the steps of preparation were performed in conditions preventing contamination with metals. Certification was done on the basis of world-wide intercomparison in which 63 laboratories from 22 countries participated using various analytical methods and techniques. Data evaluation was performed by means of software package SSQC. Several criteria were also employed to decide whether the overall mean can be given the status of recommended (certified) or information value.
