Overview

EN 10211:2013 is a CEN European Standard that specifies a flame atomic absorption spectrometric (FAAS) method for the chemical analysis of titanium in steels and cast irons. The method applies to non-alloyed and alloyed steels and cast irons with titanium contents from 0.01 % to 1.0 % (m/m). It defines sample preparation, reagent and apparatus requirements, instrument performance checks, calibration and result expression for reliable titanium determination.

Key topics and technical requirements

• Analytical technique: Flame atomic absorption spectrometry (FAAS) using a titanium hollow‑cathode lamp (spectral lines 365.3 nm or 364.3 nm) with a slightly fuel‑rich nitrous oxide/acetylene flame.
• Sample dissolution: Two validated procedures:
  • Nitric–perchloric dissolution (specific to cast irons) with filtration to remove silica.
  • Chloro‑nitric dissolution with residue treatment (applicable to steels and cast irons) including HF treatment and fusion of residue with boric acid/sodium carbonate.
• Matrix buffering: Addition of aluminium chloride as an interaction buffer in final solutions.
• Instrument performance criteria:
  • Limit of detection (LOD): better than 0.2 µg/ml (365.3 nm) and 0.1 µg/ml (364.3 nm).
  • Characteristic concentration: better than 1.9 µg/ml (365.3 nm) and 1.4 µg/ml (364.3 nm).
  • Precision checks: standard deviation limits for repeated absorbance measurements and calibration linearity requirements (top 20% slope ≥ 0.7 × bottom 20% slope).
• Test portion and blanks: Typical test portion = 1 g; blank determinations and iron matrix standards are specified.
• Documentation: Requirements for expression of results, test reports and annexed precision data and instrumental tests.

Applications and practical value

• Provides a standardized, reproducible procedure for titanium determination in steel and iron for:
  • Quality control in steel mills and foundries
  • Incoming material inspection and alloy verification
  • Failure analysis and metallurgical R&D
  • Contractual testing where traceable, comparable results are required
• Ensures consistent sample preparation, instrument calibration and performance verification, reducing variability between laboratories and supporting regulatory compliance.

Who should use this standard

• Metallurgical and chemical testing laboratories
• Steel producers, foundries and alloy manufacturers
• Third‑party inspection and certification bodies
• Research institutions performing elemental analysis of ferrous materials

• EN ISO 14284 - Sampling and preparation of samples for chemical composition

5.2.3 Linearity of calibration. The value of the slope of the calibration graph covering the top 20 % of the concentration range (expressed as a change in absorbance) shall not be less than 0,7 times the value of the slope for the bottom 20 % of the concentration range (expressed as a change in absorbance) determined in the same way. For instruments with automatic calibration using two or more standard solutions, it shall be established prior to the analysis, by obtaining absorbance readings, that the above requirements for graph linearity are fulfilled. 5.2.4 Characteristic concentration. The characteristic concentration for titanium in a matrix similar to the final test portion solution shall be better than 1,9 µg/ml for the 365,3 nm line and better than 1,4 µg/ml for the 364,3 nm line. 5.3 Ancillary equipment. A system for acquisition of the measured values, data processing and evaluation is necessary. Usually data processing and evaluation is performed with the appropriate software of the computer, connected to the atomic absorption spectrometer. Scale expansion can be used until the noise observed is greater than the read-out error and is preferred for absorbances below 0,1. If scale expansion has to be used and
