21/30414276 DC

This standard 21/30414276 DC BS ISO 4188. Magnesium and magnesium alloys. Determination of arsenic. 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 arsenic 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 0,6 % of cerium, 0,1 % of gadolinium, 0,2 % of neodymium and 0,8 % of zirconium.
