Significance and Use
These test methods for the chemical analysis of zinc metals and alloys are primarily intended as referee methods 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.
1.1 These test methods cover the chemical analysis of zinc and zinc alloys having chemical compositions within the following limits:
| ||Element||Concentration Range, %|
| Aluminum||0.005 to 4.5|
| || Cadmium||0.001 to 0.5|
| || Copper||0.001 to 1.3|
| || Iron||0.001 to 0.1|
| || Lead||0.001 to 1.6|
| || Magnesium||0.001 to 0.1|
| || Tin||0.001 to 0.1|
1.2 These test methods appear as follows:
|Aluminum by the EDTA Titrimetric Method (0.5 to 4.5 %) ||10-17|
|Aluminum, Cadmium, Copper, Iron, Lead, and Magnesium by the |
Atomic Absorption Method
