Plain Carbon Cast Steel Disk (0.94% C)

Spectroscopic Standard, SS-CRM 602/2, is sold as 44 mm diameter x 19 mm thick discs for spectroscopic analysis. The preparation of representative samples for chemical analysis and certification by co-operative analysis was undertaken by Bureau of Analysed Samples Ltd. These disc samples have been prepared from chill cast bars which were subjected to extensive spectrographic tests to confirm their homogeneity both radially and longitudinally. Slight porosity may be found in the centre of some of the disc samples but spectrographic examination has proved that this will not adversely affect the use of these samples provided that they are not sparked directly on to the affected area.
