BS EN 74-1:2005 Couplers, spigot pins and baseplates for use in falsework and scaffolds - Part 1: Couplers for tubes - Requirements and test procedures
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.
