DIN EN ISO 148-2 — Verification of Charpy Pendulum Impact Testing Machines

← Back to all standards

DIN EN ISO 148-2 is the German adoption of ISO 148-2, the standard for verifying Charpy pendulum impact machines used on metallic materials. The technical requirements match the ISO version; the DIN EN designation is what German and EU quality systems cite. To verify a Charpy machine to this standard, talk with our team.

What It Verifies

The standard confirms machine performance through direct measurement of pendulum geometry, friction and windage losses, and striker and anvil dimensions, together with indirect checks using certified reference pieces.

Why the DIN EN Designation Is Used

When an accreditation scope or quality plan is written to European norms, it names DIN EN ISO 148-2 rather than the bare ISO number. A current certificate to this designation is what supports Charpy results in that market.

Reading the Designation

Cited as DIN EN ISO 148-2:YYYY. Confirm the edition, since it tracks revisions of the underlying ISO standard.

Related Standards

ISO 148-2 is the base international standard, ISO 148-3 covers the reference test pieces, and DIN 51222 is a related German requirement for lower-energy pendulum machines.
