behind the exterior veneer, as
				  described in Section 1404.2, and a means for draining water that enters the
				  assembly to the exterior. Protection against condensation in the
exterior wall
assembly shall be provided in accordance with
				  Section 1405.3.

envelope
that has been demonstrated through testing to resist
				wind-driven rain, including joints, penetrations and intersections with
				dissimilar materials, in accordance with ASTM E 331 under the following
				conditions:
2.1.
Exterior
				wall
envelope
test assemblies shall include at least
				one opening, one control joint, one wall/eave interface and one wall sill. All
				tested openings and penetrations shall be representative of the intended
				end-use configuration.

envelope
assemblies shall be tested at a minimum differential
				pressure of 6.24 pounds per square foot (psf) (0.297
				kN/m2).
2.4.
Exterior wall
envelope
assemblies shall be subjected to a minimum test
				exposure duration of 2 hours.
The
exterior wall
envelope
design shall be considered to resist wind-driven rain where the results of
				  testing indicate that water did not penetrate control joints in the
exterior wall
envelope, joints at the perimeter of openings or
				  intersections of terminations with dissimilar materials.
