DIN 50125 — Tensile test pieces for metallic materials

← Back to all standards

DIN 50125 defines standardized tensile test pieces for metallic materials, covering test-piece geometry, dimensions, and how the shape relates to the gauge length. To match a setup to this test, talk with our team.

What DIN 50125 Covers

The standard specifies the flat and round test-piece forms used for metals tensile testing, including proportional and non-proportional gauge lengths, transition radii, and gripping ends. Consistent geometry is what makes results from different labs comparable.

Preparing Test Pieces

Accurate machining to the specified dimensions and radii, with clean surfaces, keeps failures in the gauge length and reduces scatter. Automated CNC preparation reproduces the geometry across a batch. To set up specimen preparation to DIN 50125, request a quote.

Reading the Designation

Cited as DIN 50125 with its year and a form code that identifies the test-piece type. Confirm the form required by the controlling test method.
