  • design requirements;

  • strength classes with different structural parameters including values for resistance and stiffness;

  • test procedures;

  • assessment;

and gives

  • recommendations for ongoing production control.

For testing, screw couplers are tightened to a torque of 50 Nm and wedge couplers are tightened with a 500 g hammer until the jarring blow.
