Overview

This International Standard specifies a spectrophotometric method for the determination of copper in steel and cast iron by 2,2'-biquinoline. The method is applicable to the determination of copper mass fraction in the range of 0,02 % and 5 %.In this revised edition, the specification of plotting the calibration graphs in 7.4.3 has been corrected. The previous edition of this standard is DIN EN 24946. The committee responsible for this standard is NA 021-00-30 AA "Analysenverfahren" ("Methods of chemical analysis") at DIN.
