ASTM E34-11 Chemical Analysis of Aluminum and Aluminum-Base Alloys
The chemical analysis of aluminum and aluminum-based alloys with a definite compositions is covered in ASTM E34-11.
Scope:
ASTM E34-11 is used for metals and alloys to ensure that the materials meet compositional standards. All users of these test methods are expected to be qualified analysts capable of completing conventional laboratory operations competently and safely. The job will most likely be done in a professionally equipped laboratory.
