Scope

1.1 This test method covers the spectrochemical analysis of aluminum and aluminum alloys for the following elements in the concentration ranges indicated:

1.2 The test method is applicable primarily to the control analysis of chill-cast samples. Other forms may be analyzed, provided that (1) they are sufficiently massive to prevent undue heating; (2) they permit machining flat surfaces having a minimum dimension of approximately 30 by 30 mm (1.2 in. by 1.2 in.); and (3) reference materials of similar metallurgical condition and chemical composition are available.

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.

Significance and Use

This test method is suitable for manufacturing control, for material or product acceptance, and for research and development. Its use over several years has shown precision and accuracy that are well within expected levels.

It is assumed that all who use this test method will be trained analysts capable of performing laboratory procedures skillfully and safely, and that the work will be performed in a properly equipped laboratory.
