|Publication Date:||31 August 2006|

This European Standard specifies, for right angle couplers, swivel couplers, sleeve couplers and parallel couplers working by friction:
- design requirements;
- strength classes with different structural parameters including values for resistance and stiffness;
- test procedures;
- 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.
