16、cimen.5. Significance and Use5.1 This test method is a standard procedure for determiningwater leakage through metal roof panel system sideseams,endlaps, and roof plane penetrations when the roof system issubjected to a specified static water pressure head.NOTE 2In applying the results of tests by t
17、his method, note that theperformance of a roof or its components or both, is in part a function ofproper installation and adjustment. In service, the performance will alsodepend on the integrity of the supporting construction, roof slope, and onthe resistance of components to deterioration by variou
18、s causes: corrosiveatmosphere, aging, ice, vibration, thermal cycling, etc. It is difficult tosimulate the identical complex wetting, aging, and other variable condi-tions that can be encountered in service, including wind-blown pondedwater; the effects of temperature and age on sealant performance;
19、differential pressure across the joints due to wind, snow, and iceaccumulation; densification and migration; and abrasions within the jointcomponents which may occur during thermal cycling and other weatherevents. Some joint conditions are more sensitive than others to thesefactors.5.2 This test met

It will not evaluate panel resistance to winddriven rain.NOTE 3See Test Method E1646 for a test which evaluates resistanceto wind driven rain.5.3 This test method is not a structural a

Apparatus6.1 This description of apparatus is general in nature andany arrangement of equipment capable of performing the testprocedure within the allowable tolerances is permitted.NOTE 4One such alternate test apparatus arrangement consists ofperimeter seals erected on top of the test
23、 specimen.6.2 Test Chamber(See Figs. 1 and 2). A well-sealedchamber or box with either an opening, a removable mountingpanel or one open face in which or against which the specimenis installed and sealed. The test chamber shall be maintained ina horizontal position.6.2.1 The test chamber shall be pr
24、ovided with a horizontalperimeter support ledge to which test specimens may beattached and sealed.6.2.2 The test specimen shall be anchored to the testchamber perimeter to adequately resist imposed test loadswithout leakage or failure.6.2.3 The test chamber shall be provided with a verticalwater dam
25、 around the perimeter of the chamber. Water damshall be well sealed and of sufficient height to maintain therequired water pressure head.6.2.4 A means of viewing all areas under the roof panelspecimen shall be provided to facilitate observations for waterleakage. It is important to isolate perimeter
26、 leakage fromleakage in areas under evaluation. For factory assembledcomponents, this may be accomplished by omitting any sealantfrom joints of the interior metal skin.FIG. 1 Plan of Typical Three-Span Test Specimen Mounted in ChamberE2140 01 (2009)26.3 Water Pressure Head Measurement DeviceA cali-b

Each deviceshall be located directly over a perimeter support ledge, and notmore than 1.0 in. (25 mm

Test Specimens8.1 Roof test specimens shall be of sufficient size todetermine the performance of all typical parts of the roofs
29、ystem.8.2 For roofs constructed with prefabricated or preformedunits or panels, the specimen width shall not be less than threetypical units plus supporting elements at each side.8.3 The specimen shall include at least four sideseams andat least two panel endlaps in adjacent panels in accordance wit

If two sp
31、ans are used, they shall be unequal, with theshorter being 75 % of the longer. If three or more spans areused, they shall be equal in length. One span of the testspecimen shall not be less than the maximum span to be usedin a roof application.8.5 All parts of the roof test specimen shall be full siz

Specimenattachments and seals at test chamber perimeters are exemptfrom this requirement. Composite systems tested shall utilize
33、 asubstrate of the same stiffness to be used in the field assembly.8.6 The specimen perimeter shall be well sealed and struc-turally attached to the test apparatus perimeter to isolateleakage through the test specimen from leakage through theperimeter. For composite roof systems, remove internal ors
34、econdary seals and disrupt all possible channels that maycarry leakage to the perimeter of the test specimen. Thesubstrate of field assembled composite roof systems shall bemade discontinuous so that any leakage through the externalskin is readily identified as such.8.7 Structural panel supports sha

(75 mm) ifrequired and maintain for a minimum of 5
39、 min.NOTE 9A small amount of perimeter seal leakage is permittedprovided that it does not impede the determination of water leakage on theinside face of the roof panel specimen.9.3 Increase the water pressure head to 6 in. (150 mm).9.3.1 Maintain the 6 in. (150 mm) 60.2 in. (5 mm) waterpressure head
