ASTM E92-26 — Vickers and Knoop Hardness Tests
Procurement reference for Vickers and Knoop 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 E92-26 covers Vickers and Knoop indentation hardness testing of metallic materials within the test conditions stated by the authorised publication.
These methods can support evaluation of thin or small regions and specific constituents where a suitable specimen and measurement route are used.
The governing product standard must define the method, test condition, preparation, location, result format and acceptance criteria.
Scope Boundary
Vickers and Knoop results are empirical and method-specific. They do not establish grade equivalence, composition or universal wear performance.
