Additional information

1. Scope

1.1 This test method provides for the optical emission spectrometric analysis of aluminum and aluminum alloys, in cast or wrought form, for the following elements in the concentration ranges indicated:

Element Concentration, Range, % Silicon 0.001 to 24.0 Copper 0.001 to 20.0 Magnesium 0.001 to 11.0 Zinc 0.001 to 10.0 Tin 0.001 to 7.5 Nickel 0.001 to 4.0 Iron 0.001 to 3.5 Lithium 0.005 to 3.0 Manganese 0.001 to 2.0 Cobalt 0.001 to 2.0 Silver 0.001 to 1.5 Chromium 0.001 to 1.0 Zirconium 0.001 to 1.0 Lead 0.002 to 0.7 Bismuth 0.001 to 0.7 Cadmium 0.001 to 0.5 Beryllium 0.0001 to 0.5 Titanium 0.001 to 0.5 Antimony 0.001 to 0.5 Vanadium 0.001 to 0.15 Strontium 0.0001 to 0.07 Gallium 0.001 to 0.05 Sodium 0.0001 to 0.05 Boron 0.0001 to 0.05 Barium 0.0001 to 0.05 Calcium 0.001 to 0.05 Phosphorus 0.0001 to 0.01

1.2 This test method is suitable primarily for the control analysis of chill-cast specimens. 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 diameter of approximately 15 mm, 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 problems, 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 safety hazard statements are given in 8.2 and Section 10.
