ISO 3327:2009 — Hardmetal Transverse Rupture Strength
Procurement reference for transverse rupture strength testing of hardmetals and the controls needed for comparable results.
Edition control: Published, Edition 3 (May 2009); confirmed in 2026 and marked by ISO for future revision. This original MNK-G.S.A summary does not reproduce or replace the protected ISO publication. Confirm the current authorised edition and governing order documents before use.
Scope in Procurement
ISO 3327:2009 defines a test route for determining transverse rupture strength of hardmetals.
The method is intended for materials with negligible ductility. Where a specimen undergoes meaningful plastic deformation, the reported result can lose its intended validity and should be treated only as comparative evidence.
A strength value cannot be interpreted without specimen geometry, preparation, support and loading conditions, test report and product traceability.
