1.1 This test method covers the spectrographic analysis of aluminum and aluminum alloys for the following elements in the ranges indicated:Element Concentration Range, % Silicon 0.02 to 14.0 Copper 0.001 to 10.0 Magnesium 0.001 to 10.0 Zinc 0.03 to 8.0 Nickel 0.03 to 3.0 Iron 0.02 to 2.0 Manganese 0.005 to 2.0 Lead 0.03 to 0.7 Bismuth 0.03 to 0.7 Chromium 0.01 to 0.5 Titanium 0.01 to 0.5 Tin 0.01 to 0.5 Beryllium 0.0002 to 0.5 Calcium 0.0005 to 0.1 Sodium 0.0005 to 0.05
1.2 This test method is applicable primarily to the analysis of chill-cast disks, but it may be extended, with proper precautions, to the analysis of samples in other forms on which a flat surface for sparking can be machined. Standards and samples should be of similar composition and metallurgical state; when they are not, corrections must be applied to compensate for these effects.
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.
