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.
