Popis
BS 6200-3.19.1:1985
This standard BS 6200-3.19.1:1985 Sampling and analysis of iron, steel and other ferrous metals. Methods of analysis. Determination of molybdenum is classified in these ICS categories:
- 77.080.01 Ferrous metals in general
This International Standard specifies a photometric method for the determination of the molybdenum content of steels and cast irons.
The method is applicable to steels and cast irons having molybdenum contents between 0,003 and 9 % (m/m).
Vanadium and tungsten interfere with the measurement if, because of their contents, the V/Mo ratio is greater than 16 or the W/Mo ratio is greater than 8.
NOTE Greater V/Mo or W/Mo ratios (up to 300) may, however, be permitted, but in such cases it is necessary to carry out the measurement very quickly after the extraction.
