Scope:
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; 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.
本欧洲标准规定，直角耦合器，旋转耦合器，套筒耦合器和并联耦合器摩擦工作:材料;设计要求;具有不同结构参数的强度等级，包括阻力值和刚度值;测试程序;评估;并对持续生产控制提出建议。为了测试，螺杆耦合器被紧固到50纳米的扭矩和楔形耦合器被紧固与一个500克的锤子，直到震动打击。
