DIN 51306 — Verification of Pendulum Impact Testing Machines

← Back to all standards

DIN 51306 was a German standard associated with verifying pendulum impact testing machines. It has been withdrawn and replaced by current references, so new work should follow the standards that superseded it. To align a legacy DIN 51306 requirement with a current method, talk with our team.

Status and Replacement

DIN 51306 is no longer maintained. Pendulum impact machine verification for metallic materials is now handled by the current Charpy verification standards, which cover direct geometry checks and indirect checks with reference test pieces.

What to Use Instead

For a defensible, up-to-date verification, use the current standards rather than the withdrawn document:

  • DIN EN ISO 148-2 for the German and European verification of Charpy pendulum machines.
  • ISO 148-2 for the international machine-verification method.
  • ISO 148-3 for the certified reference test pieces used in indirect checks.

Why It Still Comes Up

Older drawings, procedures, and quality records may still cite DIN 51306. When that happens, the practical step is to map the legacy requirement onto the current Charpy verification standards and document the equivalence.

Related Standards

DIN EN ISO 148-2, ISO 148-2, and ISO 148-3 are the current references for pendulum impact machine verification.
