5.1 This test method for the analysis of aluminum and aluminum alloys is primarily intended to test material for compliance with The Aluminum Association Inc.5 registered composition limits or other specified composition limits for aluminum and aluminum alloys.
5.2 It is assumed that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely, and that the work will be performed in a properly equipped laboratory.
5.3 This is a performance-based test method that relies more on the demonstrated quality of the test result than on strict adherence to specific procedural steps. It is expected that laboratories using this test method will prepare their own work instructions. These work instructions should include detailed operating instructions for the specific laboratory, the specific reference materials employed, and performance acceptance criteria.
