These test methods cover the chemical analysis of magnesium and magnesium alloys having chemical compositions within the following limits:

Aluminum, %0.5 to 12 Copper, %0.005 to 0.1 Iron, %0.002 to 0.1 Lead, %0.001 to 0.5 Manganese, %0.01 to 2.0 Nickel, %0.0005 to 0.5 Rare earth elements, %0.2 to 10 Silicon, %0.01 to 0.8 Thorium, %0.2 to 25 Tin, %0.5 to 10 Zinc, %0.3 to 20 Zirconium, %0.03 to 1.0 Magnesium, %remainder

Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials; these test methods were withdrawn in September 2008. This standard was withdrawn with no replacement because it does not contain bias or precision data for any of the test methods and this information is now required to be included.

Значение и использование

These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.
