19、rame.4. Summary of Test Method4.1 This test method consists of sealing a chamber to the interior or exterior face of specimen to be tested, supplying air to achamber mounted on the exterior or exhausting air from a chamber mounted on the interior, at the rate required to maintain thetest pressure di

20、fference across the specimen while spraying water onto the outdoor face of the specimen at the required rate andobserving any water penetration.5. Significance and Use5.1 This test method is a standard procedure for determining the resistance to water penetration under uniform or cyclic staticair pr

21、essure differences of installed exterior windows, skylights, curtain walls, and doors. The air-pressure differences acting acrossa building envelope vary greatly. These factors should be considered fully prior to specifying the test pressure difference to be used.NOTE 1In applying the results of tes

22、ts by this test method, note that the performance of a wall or its components, or both, may be a function of properinstallation and adjustment. In service, the performance will also depend on the rigidity of supporting construction and on the resistance of componentsto deterioration by various cause

23、s, vibration, thermal expansion and contraction, and so forth. It is difficult to simulate the identical complex wettingconditions that can be encountered in service, with large wind-blown water drops, increasing water drop impact pressures with increasing wind velocity,and lateral or upward moving

24、air and water. Some designs are more sensitive than others to this upward moving water.NOTE 2This test method does not identify unobservable liquid water which may penetrate into the test specimen.5.2 Laboratory tests are designed to give an indication of the performance of an assembly. Field perfor

25、mance may vary fromlaboratory performance since the supporting structure for the test specimen, methods of mounting, and sealing in the laboratorycan only simulate the actual conditions that will exist in the building. Shipping, handling, installation, acts of subsequent trades,aging, and other envi

26、ronmental conditions all may have an adverse effect upon the performance of the installed product. This fieldtest procedure provides a means for determining the performance of a product once installed in the building.5.3 The field test may be made at the time the window, skylight, curtain-wall, or d

27、oor assemblies are initially installed andbefore the interior of the building is finished. At this time, it is generally easier to check the interior surfaces of the assemblies forwater penetration and to identify the points of penetration. The major advantage of testing when assemblies are initiall

28、y installedis that errors in fabrication or installation can be readily discovered and corrections made before the entire wall with its componentassemblies is completed at which time the expense of corrective work may be increased many times.5.4 The field test may also be made after the building is

29、completed and in service to determine whether or not reported leakageproblems are due to the failure of the installed assemblies to resist water penetration at the specified static air pressure difference.Generally it is possible to conduct tests on window, skylight, and door assemblies without too

30、much difficulty, and to identifysources of leakage. A curtain-wall assembly, on the other hand, may not be accessible from the inside without the removal ofinterior finished walls and ceilings. Even with removal of interior walls and ceilings, it may not be possible to observe curtain-wallsurfaces b

31、ehind spandrel beams. The feasibility of conducting a meaningful static air pressure difference water penetration test onan in-service building must be carefully evaluated before being specified.5.5 Weather conditions can affect the static air pressure difference measurements. If wind gusting causes

32、 pressure fluctuationto exceed 6 10 % 610 % from the specified test pressure, the test should not be conducted.5.6 Generally it is more convenient to use an interior mounted pressure chamber from which air is exhausted to obtain a lowerpressure on the interior surface of the specimen. A calibrated r

33、ack of nozzles is then used to spray water at the proper rate on theexterior surface. Under circumstances where it is desirable to use an exterior-mounted pressure chamber, the spray rack must belocated in the pressure chamber and air supplied to maintain a higher pressure on the exterior surface. E

34、xterior chambers aredifficult to attach readily and seal to exterior surfaces.5.7 Even though the equipment requirements are similar, this procedure is not intended to measure air infiltration because ofthe difficulty of isolating the component air leakage from the extraneous leakage through weep ho

Apparatus6.1 The description of apparatus in this section is general in nature, and any arrangement of equipment capable of performingthe test procedures within allowable tolerances is permitted.6.2 Major Components (Fig. 1):6.2.1

36、Test ChamberA test chamber or box made of plywood, plastic, or other suitable material and sealed against the testspecimen. Test chambers mounted on the interior must be made so that interior surfaces and joints of the specimen can be easilyobserved for water penetration during the test. No part of

37、the testing chamber shall come in contact with or restrict any point wherewater pentrationpenetration may occur. At least one static air pressure tap shall be provided to measure the chamber air pressureversus the ambient (interior-exterior) air pressure and shall be so located that the reading is u

38、naffected by exterior impinging wind,or by the velocity of air supply to or from the chamber. The air supply opening into or exhaust from the chamber shall be arrangedso that air does not impinge directly on the test specimen with any significant velocity. A means of access into the chamber maybe pr

39、ovided to facilitate adjustments and observations after the chamber has been installed.6.2.2 Air SystemA controllable blower, compressed air supply exhaust system, or reversible blower designed to supply therequired maximum air pressure difference across the specimen. The system must provide essenti

40、ally constant air flow at a fixedpressure for the required test period.6.2.3 Pressure Measuring ApparatusA device to measure the test pressure difference within a tolerance of 62 % or 62.5 Pa(60.01 in. 60.01 in. (62.5 Pa of water column), whichever is greater.6.2.4 Water-Spray SystemThe water-spray

41、system shall deliver water uniformly against the exterior surface of the testspecimen at a minimum rate of 3.4 L/m5.0 2min (5.0 U.S. gal/ft2h).h (3.4 Lm2min).NOTE 3The National Weather Service Technical Paper No. 403 records that in the contiguous 48 United States, the greatest rainfall for a 1-h pe

42、riodis less than 12.7 cm (5.0 in.). The rate of 3.4 L/m2min (5.0 U.S. gal/ft2h) specified in this test method corresponds to a rainfall of 20.3 cm (8.0 in.)/hunless otherwise specified.6.2.4.1 The water-spray system shall have nozzles spaced on a uniform grid, located at a uniform distance from the

43、testspecimen and shall be adjustable to provide the specified quantity of water in such a manner as to wet all of the test specimen,FIG. 1 General Arrangement of Water Penetration Test ApparatusE1105 153uniformly and to wet those areas vulnerable to water penetration. If additional nozzles are requi

44、red to provide uniformity of waterspray at the edge of the test specimen, they shall be equally spaced around the entire spray grid.6.2.4.2 The intake water line to the nozzle grid shall be equipped with a pressure gage and pressure adjusting valve. For fieldtesting, the water pressure shall be adju

45、sted to the same pressure at which the water spray system was calibrated.7. Hazards7.1 WarningGlass breakage will not normally occur at the small pressure differences applied in this test method. Excessivepressure differences may occur, however, due to error in operation or gusting wind, therefore,

46、exercise adequate precautions toprotect personnel.7.2 Take whatever additional precautions are necessary to protect persons from water spray, falling objects (which may includetools), the spray system, or even the exterior test chamber.8. Examination of Test Specimens8.1 Select and identify the test
