Testing

This sets out the design and performance requirements for sheet roof and wall cladding systems specifically for New Zealand, and the process of assessing compliance with these standards. Some commentary is provided to explain the background to the practical test methodology.

Currently, Testing covers uniformly distributed wind load (UDL) and concentrated (point load) for sheet roof and wall cladding.

These procedures apply to all metals and plastic sheeting however because of their different characteristics some of the performance criteria are different.
