Popis
21/30414270 DC
This standard 21/30414270 DC BS ISO 4177. Magnesium and magnesium alloys. Determination of chromium. Inductively coupled plasma optical emission spectrometric method is classified in these ICS categories:
- 77.120.20 Magnesium and magnesium alloys
This document specifies an inductively coupled plasma optical emission spectrometric method (ICP-OES) for the determination of chromium contents between 0,001 0 % (mass fraction) and 0,050 % (mass fraction) in magnesium and magnesium alloys.
The method is limited to magnesium alloys containing contents less than 1,0 % of cerium, 3,2 % of gadolinium, 0,2 % of neodymium and 1,6 % of manganese.
