标准简介
This document describes the 8-hydroxyquinoline spectrophotometric method, the chrome azurol S-tetradecylpyridinium chloride spectrophotometric method and the 8-hydroxyquinoline gravimetric method for the determination of the aluminium content of magnesium and magnesium alloys. This document is applicable to the determination of the aluminium content of magnesium and magnesium alloys. The 8-hydroxyquinoline spectrophotometric method is applicable to magnesium and magnesium alloys with a zirconium mass fraction not greater than 1.5 %, with a determination range (mass fraction) of 0.020 % to 0.300 %; the chrome azurol S-tetradecylpyridinium chloride spectrophotometric method is applicable to magnesium and magnesium alloys not containing titanium, zirconium, beryllium, silver or rare earths, with a determination range (mass fraction) of 0.001 0 % to 0.300 %; the 8-hydroxyquinoline gravimetric method is applicable to magnesium and magnesium alloys not containing zirconium, thorium or rare earths, with a determination range (mass fraction) of 1.50 % to 12.00 %.
