The NZMRM employs specific testing methods and standards to evaluate the performance of metal roofing components and accessories.
Structural testing of profiled metal closely follows the standards AS 1562 and AS 4040, but differs in minor areas to suit NZ requirements. This testing is used to demonstrate compliance with NZBC B1 – Structure
Compliance with NZBC B2 – Durability is demonstrated by testing of profiled metal and fasteners. This testing is based on AS/NZS2728 and AS/NZS 3566 respectively, again with some modifications.
Also included, are the MRM soft edge standard, and testing and performance standard for pre-painted coil.
