[more]Scaffolding – couplers and accessories – revised Standard published
Standards New Zealand has published the latest revision of AS/NZS 1576.2:2009 Scaffolding – Couplers and accessories. Scaffolding suppliers, building consultants, and engineers use AS/NZS 1576.2:2009 to ensure the proper operation of couplers and accessories for light, medium, heavy, and special duty scaffolding.
The testing appendices have been revised and new tests have been included for bending load capacity for end-to-end couplers, determination of slip resistance using a check coupler, horizontal load test on castors, and a test for a check coupler combination with a load bearing coupler.
Changes from the last revision are as follows:
- wedge-tightened couplers are now allowed (aligning with BS-EN 74-1:2005)
- couplers that meet the performance requirements of BS EN 74-1 for similar type couplers are deemed to comply with this Standard without the need for type retesting
- end-to-end couplers are not to be used to resist direct tensile forces between the joined tubes
- a bending load capacity has replaced slip performance for end-to-end couplers
- new suppliers' documentation that includes servicing procedures
- new tests for determination of slip resistance and horizontal loads on castors.

- if the thermal mass of the masonry is isolated from the interior where a wall is strapped and lined.
