DIN 51222 — Pendulum impact testing machines (≤ 50 J) requirements and verification
DIN 51222 sets particular requirements and verification expectations for pendulum impact testing machines with a nominal energy of 50 J or less, used for notched impact bending tests. Lower-energy machines need tighter attention to friction and geometry, which this standard addresses. To verify or specify a low-energy impact machine, talk with our team.
What DIN 51222 Covers
The standard defines the machine requirements and checks that matter most at low impact energies, where friction and windage losses and small geometric errors have a proportionally larger effect on the measured absorbed energy.
Why It Matters
At 50 J and below, the same absolute error in energy loss represents a larger relative error in the result. DIN 51222 tightens the verification of pendulum geometry, bearing friction, and the energy-indicating system so that low-energy impact data stays reliable.
Reading the Designation
Cited as DIN 51222 with its edition year. Confirm the edition and whether a European (DIN EN ISO 148-2) verification is also required for your scope.
