While ASTM E1251-17a was a primary version, it has since been superseded by more recent updates, including and ASTM E1251-25 . Users seeking the ASTM E1251-17a PDF can find it on the official ASTM International website or through authorized standards distributors like Intertek Inform and Scribd . Scope and Application
Defines the applications, stating it is primarily suitable for chill cast disks , though other forms can be used if they meet specific criteria. The ASTM E1251-17A PDF document outlines the necessary
It is important to note that Mercury (Hg) is from the scope. The Spark-AES method is not recommended for Hg analysis due to an intense iron spectral interference that can lead to inaccurate results. For compliance with strict regulatory limits, an alternative method such as XRF, ICP-MS, or cold vapor atomic absorption is required.
In simple terms, it provides a uniform procedure for using a spark spectrometer to measure the chemical composition of aluminum. This includes determining the percentage of alloying elements (like silicon, copper, magnesium) and impurities (like iron). To maintain accuracy, the spectrometer must be regularly
: Specimens must be "massive" enough to prevent over-heating during the spark process. ASTM International 🧪 Elements Analyzed
: Verify that aluminum products meet exact customer and industry specifications.
: This high-energy spark vaporizes a tiny amount of the material, exciting the electrons of the atoms within the sample.
A: Yes, but pay attention to the lower limits of detection (LODs) in the precision section. For ultra-trace analysis, ICP-MS may be required.
