EN 10274 – Metallic materials: drop weight tear test (DWTT)

← Back to all standards

EN 10274 is the European standard for the drop-weight tear test (DWTT) of metallic materials. To match this to your program, talk with our team.

What EN 10274 Covers

It evaluates the fracture behaviour of steel, particularly line pipe, against running brittle fracture, under the European framework.

How the Test Is Run

A notched full-thickness specimen is broken by a falling weight, and the percentage of ductile fracture is assessed against requirements.

Why It Matters

DWTT governs fracture-control acceptance of pipeline steels; a drop-weight machine sized for the specimen is required.
