ISO 4499-2:2020 — WC Hardmetal Grain Size
Procurement reference for metallographic measurement of WC grain size in tungsten-carbide hardmetals.
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 4499-2:2020 gives a metallographic route for measuring WC grain size in WC/Co hardmetals using optical or electron microscopy.
The method uses linear-intercept analysis and addresses microscope calibration, statistically meaningful measurement, calculation and reporting controls.
It is not a method for defining a full size distribution or particle shape, and magnetic coercivity measurements are outside this metallographic route.
| Measured feature | WC grain size |
| Material context | Primarily WC/Co hardmetals |
| Method context | Optical or electron microscopy with linear-intercept analysis |
| Scope boundary | Not a full size-distribution, shape or coercivity method |
Where This Standard Fits
- WC-Co grade and production qualification
- Comparing documented grain-size results
- Specifying microscopy and reporting expectations
- Separating average grain size from powder or distribution claims
Ordering and Document Controls
- Exact standard part and edition
- Grade, batch, sampling and specimen preparation
- Microscope type, calibration and image quality
- Field selection and linear-intercept dataset
- Calculation, uncertainty and reported result
- Customer acceptance route and laboratory traceability
