ASTM E18-25 — Rockwell Hardness Test Methods
Procurement reference for Rockwell and Rockwell superficial hardness testing of metallic materials.
Edition control: Active. Confirm the current authorised edition and the governing product or order specification before use. This original MNK-G.S.A summary does not reproduce or replace the protected ASTM publication.
Scope in Procurement
ASTM E18-25 covers Rockwell and Rockwell superficial indentation hardness testing of metallic materials.
The selected scale must suit the material, expected hardness, product thickness, test surface and governing product requirement.
The report should identify the scale, location, result, equipment control and traceability required by the order.
Scope Boundary
A Rockwell result at one location may not represent the whole product. Specific material standards may require another hardness method or additional controls.
Ordering and Test-Report Controls

- Material grade, product form, condition and batch identity
- Specimen location, orientation, preparation and test quantity
- Required temperature, unit system or hardness scale as applicable
- Equipment verification, laboratory requirements and traceability
- Result format, acceptance criteria, retest route and inspection document
