Foreword
GB/T 8654 This section includes the phenanthroline spectrophotometric method and the titanium trichloride - potassium dichromate titration Determination of two metal manganese,
Silicon manganese alloys, manganese and ferromanganese analysis of iron content.
This Part replaces GB/T 8654.1-1988 "Methods for chemical analysis of manganese metal phenanthroline spectrophotometric determination of the amount of iron" and
GB/T 8654.2-1988 "Methods for chemical analysis of manganese metal - The titanium trichloride - potassium dichromate volumetric method for the determination of iron content."
This portion of the GB/T 8654.1-1988 and GB/T 8654.2-1988 comparison, the main changes are as follows.
--- Methods to extend the scope of the metal manganese metal manganese, silicon manganese alloys, manganese and ferromanganese;
--- Increased silicon manganese alloys, manganese and ferromanganese sample decomposition method;
--- Adjusted by the spectrophotometric measurement range from 0.001% to 0.31% and titration 1.00% to 5.00% of the spectrophotometry
0.001% to 1.00% and 1.00% titration ~ 35.00%;
