2、year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of the res

3、is-tance of exterior windows, curtain walls, skylights, and doorsto water penetration when water is applied to the outdoor faceand exposed edges simultaneously with a cyclic static airpressure at the outdoor face higher than the pressure at theindoor face.1.2 This test method is applicable to any cu

Summary of Test Method4.1 This test method consists of sealing the test specimeni

12、 anywater penetration.5. Significance and Use5.1 This test method is a standard procedure for determiningthe resistance to water penetration under cyclic static airpressure differences. The air-pressure differences acting acrossa building envelope vary greatly. These factors should be fullyconsidere

13、d prior to specifying the test pressure difference to beused.NOTE 1In applying the results of tests by this test method, 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

Apparatus6.1 The description of apparatus in this section is general innature, and any arrangement of equipment capable of perform-ing the test procedure within the allowable tolerances ispermitted.6.2 Major Component

19、s (Fig. 1):6.2.1 Test Chamber or box with an opening, a removablemounting panel, or one open side in which or against which thespecimen is installed and sealed.At least one static pressure tapshall be provided to measure the chamber pressure, and shallbe so located that the reading is unaffected by

20、the velocity ofthe air supply to or from the chamber. The air supply openinginto the chamber shall be arranged so that the air does notimpinge directly on the test specimen with any significantvelocity. A means of access into the chamber may be providedto facilitate adjustments and observations afte

If additional nozzles are required to provideuniformity of water spray at the edge of the test specimen, theyshall be equally spaced around the entire spray grid.7. Hazards7.1 WarningGlass breakage will not normally occur atthe small pressure differences appli

26、ed in this test. Excessivepressure 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 dete

28、t one typical verticaljoint 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 sp

29、ecimen, and all connec-tions 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

30、 possible.8.2 Window, skylight, 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 specif

31、ying authority.NOTE 3It should be recognized, especially with windows, that per-formance is likely to be a function of size and geometry. Therefore, selectspecimens covering the range of sizes to be used in a building. In general,the largest size of a particular design, type, construction, and confi

32、gurationto be used should 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.Th

33、e catch box shall be designed 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

34、 from entering the calibration box before and after thetimed observation interval. The water impinging on each areashall be captured separately. A spray that provides at least1.26 L/min (20 gal/h) total for the four areas and not less than0.25 L/min (4 gal/h) nor more than 0.63 L/min (10 gal/h) inan

35、y one square shall be acceptable.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

36、 be calibrated with the catch 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 wat

37、er spray rack shall be installed parallelto the plane of the specimen. Recalibrate at intervals of, notmore than, 6 months.10. Information Required10.1 The test-pressure difference or differences at whichwater penetration is to be determined, unless otherwise speci-fied, shall be 137 Pa (2.86 lbf/ft

38、2).10.2 Unless otherwise specified, 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 SystemE 547 00 (2009)3through the perimeter frame of the test specimen. Wat

39、ercontained within drained flashing, 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 durat

40、ion.10.3.2 In no case shall the total 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 t

41、he assembly as installed in or on a building.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 teste

42、d at the minimum angle from the horizontal 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 chambe

43、r opening,to seal the access door to 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 highlyflexib

44、le and has a thin contact edge.11.2 Without 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

45、operation.11.3 Submit each operable unit 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

46、 stipulated by the specification orspecifier.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

47、.1) remove the air-pressure difference and stop the waterspray.11.9 Observe and record the points of water penetration, ifany.12.
