Full title and description

Standard Test Method for Analysis of Nickel Alloys by Flame Atomic Absorption Spectrometry — a laboratory test method that specifies procedures for the determination of selected alloying and trace elements in nickel and nickel‑base alloys using flame atomic absorption spectrometry (FAAS). The method provides recommended sample preparation, calibration, measurement and quality control practices to obtain compositional results suitable for specification and quality assurance purposes.

Abstract

This standard defines a FAAS‑based analytical procedure for measuring concentrations of common alloying elements in nickel and nickel‑base alloys (for example Al, Cr, Co, Cu, Fe, Mn, Si, V) across specified concentration ranges. It includes guidance on sample dissolution, instrument calibration, measurement conditions, interlaboratory precision, and routine quality control; and it references related ASTM guidance for laboratory safety and analytical practice.

• Number of pages: 9 pages.

Scope

The standard covers analysis of nickel and nickel‑base alloys by flame atomic absorption spectrometry for determination of aluminum, chromium, cobalt, copper, iron, manganese, silicon, and vanadium (with stated nominal concentration ranges and the option to extend ranges using appropriate standards). It is intended for laboratory use where trained analysts and suitable equipment are available and does not replace safety and environmental practices required for chemical analysis.

Key topics and requirements

• Elements covered: Al, Cr, Co, Cu, Fe, Mn, Si, V (specified concentration ranges and analyte sections for each element).
• Sample dissolution and matrix preparation procedures appropriate for nickel alloys.
• Calibration strategies and use of suitable standards for extending concentration ranges.
• Instrumental FAAS operating conditions, measurement practice and signal interpretation.
• Precision statements based on interlaboratory studies and guidance on reporting limits of detection and quantitation.
• Quality control and method validation recommendations; references to Guide E882 and Practices E50 for laboratory and safety practices.

Typical use and users

Used by analytical chemistry laboratories, metal producers, heat‑treatment and alloy manufacturers, quality control/assurance teams, metallurgical laboratories, and conformity assessment bodies that require routine compositional analysis of nickel and nickel‑base alloys for specification compliance and process control. The method is suited for labs equipped for FAAS and staffed by trained analysts.

Related standards

Closely related ASTM procedures and references include other metal analysis standards and guides such as ASTM E1473 (chemical analysis of nickel, cobalt, and high‑temperature alloys), ASTM E353 (chemical analysis of stainless and chromium‑nickel‑iron alloys) and supporting guides/practices (Guide E882 for QC and Practices E50 for apparatus/reagents/safety). Users often apply this method alongside other ASTM chemical analysis standards depending on alloy type and elements of interest.
