Popis
BS 6783-12:1992
This standard BS 6783-12:1992 Sampling and analysis of nickel, ferronickel and nickel alloys is classified in these ICS categories:
- 77.120.40 Nickel, chromium and their alloys
This International Standard specifies a molecular absorption spectrometric method for the determination of the phosphorus content of nickel alloys in the range 0,001 % (m/m) to 0,025 % (m/m). Typical compositions of some nickel alloys are given in Annex A.
Chromium(III) and silica cause interference which is eliminated in the procedure. See clause 9.
For phosphorus in the range 0.001%(m/m) to 0.025%(m/m).
