Summary of Test Method4.1 The test consists of sealing and fixing a test specimen toa horizontal support frame, locating vertical water dams aroundthe perimeter of the test specimen, applying a specified staticwater head
13、 to the outside face of the test specimen andobserving for water leakage on the underside of the testspecimen.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

In service, the performance will alsodepend on the integrity of the supporting construction, roof slope, and onthe resistance of components to deterioration by various causes: corrosiveatmosphere, aging, ice, vibration, thermal cycling, etc. It
17、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,differential pressure across the joints due to wind, snow and ice accumu-lation,
18、 densification and migration, and abrasions within the joint compo-nents which may occur during thermal cycling and other weather events.Some joint conditions are more sensitive than others to these factors.5.2 This test method will evaluate the resistance of roofpanels, sideseams, endlaps, and roof
19、 plane penetrations towater submersion. It will not evaluate panel resistance to winddriven rain.NOTE 3See E 1646 for a test which evaluates resistance to winddriven rain.5.3 This test method is not a structural adequacy test.5.4 This test method is applicable to single skin metalpanels, the exterio
20、r skin of factory assembled compositepanels, and the exterior skin of field assembled compositesystems as long as means can be provided to distinguishleakage through the exterior panel sideseams/endlaps andperimeter leakage.6. Apparatus6.1 This description of apparatus is general in nature andany ar
21、rangement 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 specimen.6.2 Test Chamber(See Figs. 1 and 2). A well-sealedFIG. 1 Plan of Typical Thre

The test chamber shall be maintained ina hori
23、zontal position.6.2.1 The test chamber shall be provided 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
24、chamber shall be provided with a verticalwater dam 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
25、waterleakage. It is important to isolate perimeter leakage fromleakage in areas under evaluation. For factory assembledcomponents, this may be accomplished by omitting any sealantfrom joints of the interior metal skin.6.3 Water Pressure Head Measurement DeviceA cali-brated scale capable of measuring
26、 the water pressure headwithin a tolerance of 60.1 in. (3 mm).6.3.1 Four water pressure head measurement devices shallbe used, and shall be located as shown in Fig. 1. Each deviceshall be located directly over a perimeter support ledge, and notmore than 1.0 in. (25 mm) from the base of the sidelap.7
27、. Safety Precautions7.1 Adequate precautions shall be taken to protect personnelfrom test chamber or test specimen failure during loading.8. Test Specimens8.1 Roof test specimens shall be of sufficient size todetermine the performance of all typical parts of the roofsystem.8.2 For roofs constructed
28、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 withmanufacturers standard details.
29、 The center line of the panelsideseams must be at least 6 in. (150 mm) from the perimeterof the test assembly as shown in Fig. 1.8.4 The test specimen shall be installed as a multiple-spancondition, unless the panel is used only in single-span appli-cations. If two spans are used, they shall be uneq
30、ual, 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 size,using the same materials, deta
31、ils, seals, and methods ofconstruction and anchorage in accordance with manufacturersstandard written and/or illustrated instructions. Specimen at-tachments and seals at test chamber perimeters are exemptfrom this requirement. Composite systems tested shall utilize asubstrate of the same stiffness t
32、o 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 orsecondary seals and disrupt all poss
33、ible 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 shall be the same size andshape as spe
34、cified in manufacturers standard written and/orillustrated instructions. Structural supports shall be designed tosupport test loads.8.8 Roof insulation shall not be included unless it is anintegral part of the roof panel system.9. Procedure9.1 Remove any sealing material or construction that is notn
35、ormally a part of the typical panel assembly.NOTE 5When full length brake-forming is available, the test panels atthe side rails can be bent upward to form effective side seals.NOTE 6Non hardening mastic compounds or pressure sensitive tapescan be used effectively to seal the test panel assembly to

(75 mm)of water pressure head. Maintain water level for a minimum of5 minutes.NOTE 8The use of room-temperat
37、ure water is recommended to avoidcondensation which may interfere with the observations of water leakage.9.2.1 Examine perimeter seals and repair as necessary.Restore water pressure head to approximately 3 in. (75 mm) ifrequired and maintain for a minimum of 5 min.NOTE 9A small amount of perimeter s
38、eal 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 for a period of 6 h.9.3.2 Record the wa
39、ter pressure head and observe for waterleakage on the inside face of the roof panel specimen 1 h afterthe start of the test, 3 h after the start of the test, andimmediately prior to test termination.9.3.3 The test procedure shall be terminated after6horupon observation of water leakage on the inside
40、 face of the roofpanel specimen.9.4 Remove all water from test specimen area. Observe andrecord condition of panels, panel endlaps and panel sideseams.10.
