Summary of Test Method4.1 This test method consists of sealing the test specimeninto or against one face of a test chamber, and supplying air toor exhausting air from the chamber at the rate requ

11、ired tomaintain the test pressure difference across the specimen forthe time cycle specified, while spraying water onto the outdoorface of the specimen at the required rate and observing anywater penetration.5. Significance and Use5.1 This test method is a standard procedure for determiningthe resis

12、tance to water penetration under cyclic static airpressure differences. The air-pressure differences acting acrossa building envelope vary greatly. These factors should be fullyconsidered prior to specifying the test pressure difference to beused.NOTE 1In applying the results of tests by this test m

13、ethod, note thatthe performance of a wall or its components, or both, may be a functionof proper installation and adjustment. In service, the performance will alsodepend on the rigidity of supporting construction and on the resistance ofcomponents to deterioration by various causes, vibration, therm

14、al expan-sion and contraction, etc. It is difficult to simulate the identical complexwetting conditions that can be encountered in service, with large wind-blown water drops, increasing water drop impact pressures with increas-ing wind velocity, and lateral or upward moving air and water. Somedesign

15、s are more sensitive than others to this upward moving water.1This test method is under the jurisdiction of ASTM Committee E06 onPerformance of Buildings and is the direct responsibility of Subcommittee E06.51on Component Performance of Windows, Curtain Walls, and Doors.Current edition approved Oct.

Hazards7.1 WarningGlass breakage will not normally occur atthe small pressure differences applied in this test. Excessive

25、pressure differences may occur, however, due to error inoperation or when the apparatus is used for other purposes suchas structural testing; therefore, exercise adequate precautions toprotect personnel.8. Test Specimens8.1 Test specimens shall be of sufficient size to determinethe performance of al

26、l typical parts of the fenestration system.For curtain walls or walls constructed with prefabricated units,the specimen width shall be not less than two typical units plusthe connections and supporting elements at both sides, andsufficient to provide full loading on at least one typical verticaljoin

27、t or framing member, or both. The height shall be not lessthan the full building-story height or the height of the unit,whichever is greater, and shall include at least one fullhorizontal joint accommodating vertical expansion such jointbeing at or near the bottom of the specimen, and all connec-tio

28、ns at the top and bottom of the units.8.1.1 All parts of the test specimen shall be full size, usingthe same materials, details, and methods of construction andanchorage as used on the actual building.8.1.2 Conditions of structural support shall be simulated asaccurately as possible.8.2 Window, skyl

29、ight, door, or other component test speci-mens shall consist of the entire assembled unit, including frameand anchorage as supplied by the manufacturer for installationin the building.8.2.1 If only one specimen is to be tested, the selection shallbe determined by the specifying authority.NOTE 3It sh

In general,the largest size of a particular design, type, construction, and configurationto be used should

31、be tested.9. Calibration9.1 The ability of the test apparatus to meet the require-ments of 6.2.4 shall be checked by using a catch box, the openface of which shall be located at the position of the face of thetest specimen. The calibration device is illustrated in Fig. 2.The catch box shall be desig

32、ned to receive only waterimpinging on the plane of the test specimen face and to excludeall run-off water from above. The box shall be 610 mm (24 in.)square, divided into four areas each 305 mm (12 in.) square.Use a cover approximately 760 mm (30 in.) square to preventwater from entering the calibra

33、tion box before and after thetimed observation interval. The water impinging on each areashall be captured separately. A spray that provides at least 1.26L/min (20 gal/h) total for the four areas and not less than 0.25L/min (4 gal/h) nor more than 0.63 L/min (10 gal/h) in any onesquare shall be acce

34、ptable.9.1.1 The water-spray system shall be calibrated at bothupper corners and at the quarter point of the horizontal centerline (of the spray system). If a number of identical, contiguous,modular spray systems are used, only one module need becalibrated. The system shall be calibrated with the ca

35、tch boxesat a distance within 651 mm (2 in.) of the test specimenlocation from the nozzle. The reference point for location of thespray system from the specimen shall be measured from theexterior glazing surface of the specimen farthest from the spraysystem nozzles. The water spray rack shall be ins

36、talled parallelto the plane of the specimen. Recalibrate at intervals of notmore than 6 months.10.

37、cified, failure criteria of this testmethod shall be defined as water penetration in accordancewith 3.2.3. Failure also occurs whenever water penetratesFIG. 2 Catch Box for Calibrating Water-Spray SystemE547003through the perimeter frame of the test specimen. Watercontained within drained flashing,

38、gutters, and sills is notconsidered failure.10.3 The periods of time during which the specimen is to besubjected to pressure difference(s) shall be specified.10.3.1 In no case shall there be less than two test cycles, andno cycle shall be less than 5 min in duration.10.3.2 In no case shall the total

39、 time of pressure applicationbe less than 15 min.10.4 If this test method is to be used at other than ambienttemperatures, such temperature conditions shall be specified.11. Procedure11.1 Remove any sealing material or construction that is notnormally a part of the assembly as installed in or on a b

40、uilding.Fit the specimen into or against the chamber opening with theoutdoor side of the specimen facing both the high pressure sideof the chamber and the water spray, and in such a manner thatno joints or openings are obstructed. Skylight specimens shallbe tested at the minimum angle from the horiz

41、ontal for whichthey are designed to be installed. Seal the outer perimeter of thespecimen to the chamber wall and seal at no other points.NOTE 4Nonhardening mastic compounds or pressure-sensitive tapecan be used effectively to seal the test specimen to the chamber opening,to seal the access door to

42、the chamber, and to achieve airtightness in theconstruction of the chamber. These materials can be used to seal a separatemounting panel to the chamber. Rubber gaskets with clamping devicesmay also be used for this purpose provided that the gasket is highlyflexible and has a thin contact edge.11.2 W

43、ithout disturbing the seal between the specimen andthe test chamber, adjust all operable units included in the testspecimen so that their operation conforms to the specificationrequirements. Adjust all hardware for maximum tightnesswithout interfering with their operation.11.3 Submit each operable u

44、nit to five cycles of opening,closing, and locking prior to testing.11.4 Adjust the water spray to the specified rate.11.5 Apply the air pressure difference within 15 s andmaintain this pressure, along with the specified rate of waterspray, for the period of time stipulated by the specification orsp

45、ecifier.11.6 While maintaining the water spray, reduce the airpressure difference to zero for a period of not less than 1 min.11.7 Repeat procedure in 11.5 and 11.6 for the specifiednumber of cycles.11.8 At the conclusion of the required number of cycles (see10.3.1) remove the air-pressure differenc
