Summary of
8、 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 Use5.1 This test method is a standard procedure for determiningthe drainage efficiency of an EIFS clad wall assembly.6
9、. Apparatus6.1 Spray Box, a transparent plastic, or equivalent, boxmeasuring 622 by 241 by 184 mm (2412 by 912 by 714 in.)containing a water spray system that is sealed to the testspecimen.6.2 Water Spray System, two spray nozzles installed in thespray box, oriented to apply all the water into the s
10、lot fault andlocated 13 mm (12 in.) from the open side of the spray box and150 mm (6 in.) to the right and left of vertical center of the slotfault. A pressure regulator, flow meter, and an inline water filterto the spray nozzles control the flow rate of water sprayed intothe slot fault. The water s
11、pray system shall deliver water at arate of 106 g (0.234 lb) per minute + 10% 0%.6.3 Drained Water Container(s), a container, or containers,tared to the nearest 1.0 g (0.002 lb) of sufficient size to retainthe water drained from the test specimen.6.4 Balance, with a capacity of 20 kg (45 lb) and acc
12、uracyof 1.0 g (0.002 lb).6.5 A means of collection such as a trough, to direct thedrained water to the drained water container. The collectionmethod may also be the tared container.7. Calibration of Flow Rate7.1 Collect the water from the water spray system in a taredcontainer for a period of 15 min
13、. Obtain the weight of thecollected water and adjust the flow rate if necessary to obtaina weight of water of 1590 g (3.5 lb) to 1745 g (3.8 lb). Multiply1This test method is under the jurisdiction of ASTM Committee E06 onPerformance of Buildings and is the direct responsibility of Subcommittee E06.

Test Specimen8.1 The EIFS clad wall assembly test specimen shall be aminimum of 1220 mm (48 in.) by 2440 mm (96 in.).8.2 The test specimen shall consist of the same materialsand
16、 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 in.) from the top of the slotfault to the top of the test specimen so t
17、hat 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. This can be accomplished by edge wrapping thetest specimen with base coa
18、t 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 Photograph the test set-up.9.2 Mount and seal the spray box to the test spe
19、cimen insuch a manner that all water enters the slot fault. Center thespray box with the bottom edge of the spray box even with thebottom edge of the slot fault. Position the test specimen verticaland plumb.9.3 Place the means of water collection or the tared con-tainer on a scale balance at the bas
