Summary

Almost 200 kg of grey cast iron, to which amounts of antimony, arsenic bismuth and lead were added, was prepared in the form of eighty bars. From these bars a number of disks (32 mm diameter, 10 mm thick) were cut. Homogeneity tests within disks and between disks cut from the same and from different bars showed that the inhomogeneity is less than 1.0 and 1.5% for antimony and lead, respectively. By means of electrothermal atomic absorption spectrometry, instrumental neutron activation analysis or radiochemical proton activation analysis the following 95% confidence intervals were certified: 263.5 ± 4.4 ppm for antimony, 347.1 ± 5.8 ppm for arsenic, 33.6 ± 0.8 ppm for bismuth and 296 ± 16 ppm for lead. The reference material is available for potential users.

Referenzmaterial für graues Gußeisen, zertifiziert für Antimon, Arsen, Bismut und Blei

Zusammenfassung

200 kg graues Gußeisen mit Zusätzen von Sb, As, Bi und Pb wurden in Form von 80 Stangen hergestellt, die in Scheiben zerschnitten wurden (Durchmesser 32 mm, Dicke 10 mm). Homogenitätstests innerhalb und zwischen den Scheiben von derselben und von verschiedenen Stangen zeigten, daß die Inhomogenität für Sb bzw. Pb weniger als 1,0 bzw. 1.5% betrug. Durch elektrothermische AAS sowie durch Neutronenaktivierungsanalyse oder radiochemische Protonenaktivierungsanalyse wurden die folgenden Werte zertifiziert (95% Vertrauensintervall): 263,5 ± 4,4 ppm Sb, 347,1 ± 5,8 ppm As, 33,6 ± 0,8 ppm Bi und 296 ± 16 ppm Pb. Die Referenzmaterialien stehen Interessenten zur Verfügung.
