YB/T 190.8-2001
YB/T 190.8-2001 Methods for chemical analysis of continuous casting mold powder—The o-phenanthroline spctrophotometric and flame atomic absorption spectrometric method for the determination of iron content
Abstract
This standard specifies the method outlines, reagents, instruments, samples, analysis steps, calculation of analysis results, and allowable deviations for determining the iron content using the o-phenanthroline spectrophotometry and flame atomic absorption spectrometry methods.
This standard is applicable to the determination of iron content in continuous casting mould fluxes. Part I: o-phenanthroline spectrophotometry, determination range: 0.10% to 5.00% (mass fraction). Part II: flame atomic absorption spectrometry, determination range: 0.10% to 5.00% (mass fraction).
