    Abstract - (Show below) - (Hide below)

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