标准简介
This document describes gravimetric and titrimetric methods for the determination of the thorium content in magnesium alloys. The gravimetric method in this document is applicable to the determination of the thorium content in magnesium alloys, with a measuring range (mass fraction) of 0.200 % to 5.000 %; the titrimetric method is applicable to the determination of the thorium content in silver-free magnesium alloys, with a measuring range (mass fraction) of 0.200 % to 5.000 %. The gravimetric method in this document is the arbitration method.
