ISO 4499-1:2020 — Hardmetal Microstructure Reference
Procurement reference for metallographic photomicrographs and descriptions used in hardmetal microstructure reporting.
Edition control: Published, Edition 2 (July 2020); last reviewed and confirmed in 2026. 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 4499-1:2020 supports metallographic description of hardmetal microstructure through reference photomicrographs and defined descriptive practice.
It helps create a common reporting language, but it does not replace the other ISO 4499 parts used for grain-size measurement, complex carbide phases or porosity and carbon-related defects.
Microstructure acceptance must be tied to the exact material route, sampling plan, preparation method, magnification and governing purchase specification.
| Subject | Hardmetal microstructure description |
| Evidence | Metallographic photomicrographs and reporting terminology |
