Standard Test Methods for Chemical Analysis of Aluminum and Aluminum-Base Alloys

Fecha:
2011-08-22 /Historical
Significance and Use:

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.


Note—Shaded areas are suitable for sampling.
