Purpose of this Standard

This Standard is intended to provide a means of compliance for window and door designers, systems' suppliers, manufacturers, and specifiers with the requirements of clauses B1 Structure, and E2 External Moisture of the New Zealand Building Code, for the performance of windows and doors to be installed in exterior walls.

This Standard provides a basis for testing and certifying the strength, rigidity, air infiltration, operation of opening sashes, and water penetration of window systems.
