Scope

This Standard sets out a method for the preparation of the ash and a flame atomic absorption spectrometric method for the determination of barium, beryllium, chromium, copper, lead, lithium, manganese, nickel, strontium, vanadium and zinc in ash prepared in the laboratory from higher rank coal, coke and fly-ash.
The Standard also provides an optional flame atomic emission spectrometric method for the determination of barium, as it gives improved sensitivity over flame atomic absorption spectrometry and it is not possible to determine barium by the latter technique with some instruments.
NOTE: Two approaches, gravimetric and volumetric, have been specified for solution preparation, both give the same results provided that, in the volumetric approach, plastics volumetric ware is used.
