Astm E125117a | Pdf

ASTM E1251-17a is an international standard for analyzing aluminum and its alloys using spark-atomic emission spectrometry (Spark-AES), widely applied in the automotive and aerospace industries for quality control. It covers the analysis of alloying elements in various forms, such as castings and extrusions, and has since been superseded by the ASTM E1251-24 edition.

• Metallurgical state: Chill-cast vs. wrought vs. cast parts – calibration must match sample microstructure.
• Spark stand contamination: Argon purity, electrode shape, and sample flatness.
• Spectral interferences: Especially with high alloy content (e.g., Zn interference on Mg).
• Concentration range: Outside the validated range, results are not covered by the precision statement.
• Not for trace elements below 0.001% – other methods (GF-AAS, ICP-MS) are recommended.

: High and low concentration standardants are used to correct for instrumental drift over time. Reference Materials astm e125117a pdf
