Solid mineral fuels — Determination of phosphorus content — Reduced molybdophosphate photometric met...
ISO 622:2016 specifies a reduced molybdophosphate photometric method for the determination of the total phosphorus content of hard coal, lignites and coke. Two methods for taking the phosphorus into solution are specified, namely extraction from the coal or coke ash with acid or by repeated oxidation of the coal or coke, by acid, to remove carbonaceous matter.
Cast irons — Determination of non-combined carbon content — lnfrared absorption method after combust...
ISO/TS 10719:2016 specifies an infrared absorption method after combustion in an induction furnace for the determination of non-combined carbon content in cast irons.
The method is applicable to non-combined carbon contents between 1,0 % (mass fraction) and 3,0 % (mass fraction).
Elements ordinarily present do not interfere. However, some alloyed cast irons, when extensively heat treated, contain…
