Abstract

Sets out to classify membranes based on elastic properties, which can then be used to give guidance on the type of detailing for a specific membrane referred to in AS 3740.

Scope

This Standard sets out the performance and general test requirements for waterproof membranes as defined in AS 3740.
The Standard does not apply to metal shower trays, preformed shower bases or exposed membranes.
The Standard may also be applied to waterproof membranes used in non-residential buildings.
