ASTM B406-96(2025) — Cemented Carbide Rupture Strength

Procurement reference for transverse rupture strength testing of cemented carbides and statistically controlled result interpretation.

Edition control: Active; ASTM B406-96 reapproved in 2025. This original MNK-G.S.A summary does not reproduce or replace the protected ASTM publication. Confirm the current authorised edition and governing order documents before use.

Scope in Procurement

ASTM B406-96(2025) covers transverse rupture strength determination for cemented carbides.

The test supports evaluation of sintered strength using specimens with controlled geometry, dimensions and surface finish; suitable finished parts can provide specimens when size permits.

Transverse rupture strength is influenced by randomly distributed internal and surface flaws and is not a design value. Sampling, specimen preparation and statistical reporting must therefore remain visible.

PropertyTransverse rupture strength
Material contextCemented carbides
Procurement roleSintered-strength and quality comparison
Scope boundaryResult is statistical and is not a structural design value
