| Zusammenfassung: | A dynamic force is the product of mass and acceleration, with mass or acceleration varying over time. The calibration of dynamic forces makes it possible to determine the frequency-dependent (dynamic) properties of the force measurement application. This document serves as a guideline for the dynamic verification of materials testing machines using applied samples. The dynamic verification helps to gain knowledge regarding the dynamic behaviour of the material testing machine and substantiates the results obtained by the testing of materials. Given that the applied samples in this guideline are used without further traceability, the procedure described does not constitute a calibration but an additional verification of the dynamic properties. In the verification procedure it is assumed - as a matter of principle - that the dynamic forces exerted and displayed by the testing machine correspond to the dynamic forces acting on the sample. Mass inertia of the specimen holders should only have a negligible influence. As a rule, the materials testing machine must be equipped with dynamic compensation in which the force signal is corrected by means of acceleration measurement. As a proof of traceability, the materials testing machine must always also be statically calibrated according to DIN EN ISO 7500. |
