BS EN 74-2:2022 PDF

This document specifies:

— materials;

— design requirements;

— specified values for resistances and stiffnesses which a coupler has to achieve under test;

— test procedures and assessment;

for the following special couplers:

— screw or wedge half couplers, sleeve couplers with shear studs, right angle reduction couplers and swivel reduction couplers.

It gives recommendations for ongoing production control.

These couplers are for use principally in temporary works. Each coupler is able to be fixed to at least one side to one 48,3 mm diameter steel or aluminium tube. For the other side of reduction couplers, this document specifies requirements for the diameter and wall thickness of tubes.

Other special half couplers such as half couplers attached by riveting, used mainly for prefabricated members of scaffolds, are outside the scope of this document.

NOTE Information on design using special couplers is given in Annex B.

BS EN 74-1:2022+A1:2025 PDF

This document 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.

These couplers are intended for use in temporary works equipment for example in scaffolds erected in accordance with EN 12811-1 and falsework erected in accordance with EN 12812.

This document specifies construction, design, performance requirements and test methods for medical face masks intended to limit the transmission of infective agents from staff to patients during surgical procedures and other medical settings with similar requirements. A medical face mask with an appropriate microbial barrier can also be effective in reducing the emission of infective agents from the nose and mouth of an asymptomatic carrier or a patient with clinical symptoms.

This document is not applicable to face masks intended exclusively for the personal protection of staff. Compliance with this standard does not demonstrate compliance with the requirements of the relevant PPE regulations.
