7) Each type of irregular stress (bending moment, lateral or axial force, exceeding nominal (rated) torque) can only be permitted up to its speci

fied limit, provided none of the others can occur at the same time. If this condition is not met, the limit values must be reduced. If 30% of the bending limit moment and lateral limit force occur at the same time, only 40% of the axial limit force is permissible and the nominal (rated) torque must not be exceeded. The effects of 10% of the permissible bending moments, axial and lateral forces on the measurement result are ≤ ± 0.02% of the nominal (rated) torque.

8) Limit loads / Option 4, Code F (high-speed version): Limit loads (bending moment, lateral, axial force and oscillation width (peak-to-peak)) are reduced by 20%.
