The elements covered in the scope of this method are listed in the table below. The range shown for each element does not demonstrate the actual usable analytical range for that element. The usable analytical range may be extended higher or lower based on individual instrument capability, spectral characteristics of the specific element wavelength being used, and the availability of appropriate reference materials. Accurate analysis of Hg using this technique is compromised by the presence of an intense iron interference.

Inaccurate reporting of Hg due to these interference effects can jeopardize the current designation of aluminum production as a mercury-free process. To demonstrate compliance with legislated Hg content limits, use of an alternate method capable of analysis with a minimum reporting limit of 0. Suitable techniques include but are not limited to glow discharge mass spectrometry, XRF, and cold vapor AA. Other forms may be analyzed, provided that: 1 they are sufficiently massive to prevent undue heating, 2 they allow machining to provide a clean, flat surface, which creates a seal between the specimen and the spark stand, and 3 reference materials of a similar metallurgical condition and chemical composition are available.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific safety and health statements are given in Section Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Historical Version s - view previous versions of standard. More E Precise and accurate analyses are essential to obtaining desired properties, meeting customer specifications, and helping to reduce scrap due to off-grade material. Also, other sample forms can be melted and cast into a disk, using an appropriate mold, as described in Practices E However, it should be noted that some elements for example, magnesium readily form oxides, while some others for example, sodium, lithium, calcium, and strontium are volatile, and may be lost to varying degrees during the melting process. The aluminum specimen to be analyzed may be in the form of a chill cast disk, casting, foil, sheet, plate, extrusion, or some other wrought form or shape. The elements covered in the scope of this method are listed in the table below.
