Summary of Test Method4.1 This test method consists of sealing a spray box to thetest specimen and then concentrating a water spray into the slotfault of the test specimen.5. Significance and
9、Use5.1 This test method is a standard procedure for determiningthe drainage efficiency of an EIFS clad wall assembly.6.

Test Specimen8.1 The EIFS clad wall assembly test specimen shall be aminimum of 1220 mm (48 in.) by 2440
17、mm (96 in.).8.2 The test specimen shall consist of the same materialsand details, and be prepared by the same methods as used inactual construction.8.3 A 51 mm (2 in.) by 610 mm (24 in.) slot fault shall beconstructed in the insulation board, lamina, and other compo-nents at a distance of 304 mm (12
18、 in.) from the top of the slotfault to the top of the test specimen so that the weather resistivebarrier is exposed. The slot fault shall be centered on thevertical center line of the panel. The top and sides of the testspecimen shall be sealed at the interface of the insulation boardand substrate.
19、This can be accomplished by edge wrapping thetest specimen with base coat and reinforcing mesh. Theinsulation board edge around the perimeter of the slot faultshall be exposed. See Fig. 1.8.4 The EIFS clad wall assembly shall be cured for aminimum of 28 days prior to testing.9. Test Procedure9.1 Pho
