(Test Method)Standard Test Methods for Chemical Analysis of Zinc and Zinc Alloys
Standard Test Methods for Chemical Analysis of Zinc and Zinc Alloys
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.
SCOPE
1.1 These test methods cover the chemical analysis of zinc and zinc alloys having chemical compositions within the following limits:

1.2 These test methods appear as follows:
Sections Aluminum by the EDTA Titrimetric Method (0.5 to 4.5 %) 10-17 Aluminum, Cadmium, Copper, Iron, Lead, and Magnesium by the
Atomic Absorption Method18-28
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 6.
