Specifies methods of testing building facades for environmental loading including water penetration and air infiltration as well as structural tests. Optional tests include seismic testing, seal degradation and building maintenance unit (BMU) restraint. The tests apply to on-site as well as laboratory testing and the Standard includes informative appendices which discuss appropriate limits and background to the testing.

This Standard sets out a method for determining the performance of a representative building facade under loading. Tests include displacement of the facade or prototype, water penetration and ultimate load capacity as well as optional tests, including BMU restraint, seismic loading and seal degradation. This test method is applicable to prototype testing in a laboratory as well as on-site testing.
