Scope

This standard specifies the instrument requirements and determination
methods of chemical reagent molecular absorption spectrophotometry
(ultraviolet and visible).
This standard applies to the determination of the impurity contents in the
chemical reagent of the absorption wavelength between 200 nm ~ 850 nm
AND the qualitative and quantitative analysis of the organic chemical reagents,
indicators, and special reagents.
