Overview
EN ISO 5832-2:2025 (endorsed by CEN as EN ISO 5832-2:2025) specifies the required characteristics and test methods for unalloyed titanium intended for the manufacture of surgical implants. The fifth edition replaces the 2018 edition and harmonizes the content with other parts of the ISO 5832 series. The document covers chemical composition, microstructure and mechanical property requirements of raw implant material and lists six strength-based grades referenced in Table 2.
Note: This standard applies to raw material; mechanical properties of finished devices can differ because of design and fabrication.
Key Topics
Grades and mechanical classification: Six grades are defined (including Grade 1 ELI, Grade 1, Grade 2, Grade 3, Grade 4A and Grade 4B). Grades are distinguished primarily by tensile/proof strengths and form condition (e.g. annealed or cold-worked).
Chemical composition controls: The standard specifies the elements to be limited in unalloyed titanium for implants, including nitrogen, carbon, hydrogen, iron and oxygen, with titanium as the balance. Cobalt is noted as a controlled impurity (<0.10 % mass fraction) in the table of chemical limits.
Microstructure requirements: Titanium in the annealed condition shall have a uniform microstructure with grain size no coarser than No. 5. At ×100 magnification no inclusions, foreign phases or continuous alpha-case layers shall be visible.
Mechanical properties and testing: Tensile and bend requirements are set out for each grade. The standard details sampling, retest rules and acceptance criteria. Representative tensile test specimens are to be prepared in accordance with ISO 6892-1. Bend testing for sheet and strip uses ISO 7438 with mandrel diameters specified by grade.
Test methods and conformity: Recognized analytical procedures and referenced standards (e.g., ISO 643, ISO 6892-1, ISO 7438, ASTM E112) are mandated for verifying conformity to composition, grain size and mechanical properties.
Applications
- Production and specification of raw unalloyed titanium for medical device manufacturers (orthopaedics, dental implants, prosthetics and other surgical implant components).
- Material selection and procurement: designers and QA teams use this standard to ensure biocompatible, traceable and grade-appropriate titanium stock for downstream device manufacture.
- Regulatory and conformity evidence: supports material-level compliance during device certification and technical documentation.
Related Standards
- ISO 5832 series (other parts covering stainless steels, cobalt alloys and other metallic implant materials)
- ISO 6892-1 - Tensile testing of metallic materials (room temperature)
- ISO 7438 - Bend test for metallic materials
- ISO 643 / ASTM E112 - Grain size determination
- ASTM F67 - Related specification for unalloyed titanium for surgical applications (referenced in the bibliography)
Practical value: EN ISO 5832-2:2025 provides a clear framework for manufacturers and specifiers to control raw unalloyed titanium quality through standardized composition, microstructure, and mechanical testing - enabling consistent, grade-based supply of implantable titanium materials.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
