Overview - ISO 17054:2010 (XRF analysis of high‑alloy steel)

ISO 17054:2010 defines a routine X‑ray fluorescence spectrometry (XRF) procedure to improve analytical performance for high‑alloy steel using a “near‑by technique”. The method prescribes how to use at least one target sample (preferably a Certified Reference Material, CRM) with composition close to the unknown to correct measured concentrations and compensate matrix effects. The standard covers sample preparation, measurement, calibration, standardization and statistical process control (SPC), with precision data provided in Annexes A and B.

Key topics and technical requirements

• Near‑by technique: Use a CRM or target sample of similar composition and measure it in close sequence with the unknown sample to apply a composition‑specific correction.
• Scope of elements and concentration ranges: Applicable to many alloying elements commonly found in high‑alloy steels, including Si, Mn, P, Cr, Ni, Mo, Cu, Co, V, Ti, Nb, with defined concentration ranges studied during precision testing.
• Sample size & matrix limits: Minimum sample ~25 mm diameter, ≥5 mm thick; carbon
