Significance and Use4.1 The purpose of this test method is to assess the instal-lation adequacy and the overall effects of service-relateddeterioration (moisture, etc.) on the EIFS wall assembly asopposed

20、 to small localized areas of degradation. Resistance topull testing as determined by this test is used as one of thefactors in evaluating the EIFS assembly on a specific project.The values obtained by this test method are not purported to berepresentative of the actual wind load capacity or otherstr

21、uctural properties of a specific EIFS clad wall installation,but may be helpful in assessing such load capacities.4.2 Since this test is used for field evaluation of existingfacilities, load results obtained from this test must be inter-preted based on sound engineering practice, applicable build-in

22、g regulations, and codes having jurisdiction. It is the discre-tion of the test specifier to directly utilize the results derived bythis test method, or else to utilize the test results with anappropriate factor of safety to obtain acceptable working loadsfor each project.4.3 This method is intended

23、 for use on test specimensoccurring or installed on existing buildings. The loss ofoutward wind load resistance of an EIFS wall assembly afterexposure to moisture and other weather conditions may com-promise the ability of the cladding or other wall components toperform adequately in place. This tes

24、t method does not provideany means by which the test results may be generalized to thelarger wall area. Such efforts should be based on experienceand engineering judgement.4.4 The manner in which the test load is applied may affectthe load capacity obtained from using this test method. Adiscussion o

25、f various load application techniques and theireffects is given in Appendix X1.5. Apparatus5.1 Electronic rebar locator or metal detector sensitiveenough to locate metal studs or fasteners of the underlyingstructural framing through the EIFS assembly.5.2 Pull test frame fabricated from metal or wood

26、, asrequired, with capability of applying a concentric pull force tothe test module and distributing reaction force on adjacent wallcomponents. Pull test frame shall be provided, as a minimum,with a worm-gear winch and a nylon strap or wire rope capableof applying load to test module in controlled m

27、anner withincrementally increasing load intensities. Alternative means ofapplying a consistent load using electro-servo motors orhydraulic units are also acceptable, provided they are capableof applying consistent, uniform load. It is intended that the pulltest frame be easily transportable and relo

28、cated so that it can bereadily used on saw-horses, scaffolding, or a swing-stage. Anexample of an acceptable test frame is shown in Fig. 1.5.3 Electronic load cell with digital force gage having acapacity of at least 4450 N 1000 lbf., and an accuracy of62%.5.4 610 mm by 610 mm 24 in. by 24 in. woode

Adhere one 19mm 34 in. thick bonding panel to the surface of the EIFS inplace at each specimen location. For testing purposes, tempo-raril

31、y fasten the bolting panel at each adhered bonding plate insuccession with appropriate hardware, immediately prior totesting.NOTE 2Screw hole locations for both the bonding panels and thebolting panel must align for proper attachment; use bolting panel as adrilling template to achieve consistent scr

Primarily, this test method is intended toimplement qualitative evaluation techniques that lead to anaccumulat

33、ion of information in an orderly and efficient mannerin accordance with procedures prescribed within Guide E2128.If a hybrid method using a combination of qualitative andquantitative evaluation techniques is desired by the testspecifier, then a random number generator method may beutilized to establ

34、ish locations of test specimens required torepresent the entire building population. Include additional testspecimens at locations of suspected or potential problems, suchas below window corners, at wall base, and so forth.NOTE 3For the hybrid method using a combination of qualitative andquantitativ

35、e evaluation techniques, a selection method based on PracticeD3665 may be utilized for this purpose.6.2 Locate metal studs within wall system (or else fastenerheads at wood-framed system) using rebar locator or metaldetector, and determine elevation or height of the specimen.6.3 For stud spacing les

36、s than 610 mm 24 in. (on center),mark 610 mm by 610 mm 24 in. by 24 in. outline on thesurface of EIFS that is centered over two adjacent studs. Forstud spacing 610 mm 24 in. and greater, mark an outline onthe EIFS surface that is 610 mm 24 in. high and with a widthequal to the stud spacing plus 75 m

37、m 3 in., which is centeredover two adjacent studs. If foam fasteners are present orsuspected within the EIFS clad wall assembly, locate the headsof foam fasteners using a rebar locator, then arrange bondingpanel in manner that evenly distributes the load across the testE2359/E2359M 13 (2018)2FIG. 1

38、Pull Test FrameE2359/E2359M 13 (2018)3specimen and mark the outline on the EIFS surface. At eachoutline marked on the wall, carefully cut through the EIFSlamina, thermal insulation board, and sheathing substrate,being careful to avoid excessive vibration during specimenpreparation that may adversely

39、 affect test results. Effortsshould also be made to avoid cutting or damaging the wallstuds.NOTE 4For EIFS cladding applied directly to a masonry substrate,saw blade depth should be set to extend 3 mm 18 in. to 6 mm 14 in. intothe masonry.6.4 Adhere one 19-mm 34-in. thick, 610 mm 24 in.square plywoo

44、 lag bolts.NOTE 6If required, replace previously used screws with fresh ones asPhillips head slots become worn or damaged.7.3 Place bearing plates of pull test frame on wall and centerover previously adhered bonding panel with bolting panelattached. Fasten wire rope attachment hardware to the testmo

45、dule hardware, with load cell mounted in-line with pullforce mechanism in a manner that will measure force loads.See Fig. 6.NOTE 7Use saw-horse, scaffolding deck, or swing-stage rails totemporarily support pull test frame until sufficient load is achieved tomake test frame self-supporting. Be prepar

46、ed to re-establish temporarysupport at end of test, or in case of sudden failure of test specimen.7.4 Apply previously determined initial load to test moduleas required to hold pull test frame in place and hold for oneminute. Record load from force gage at beginning of load stepand at end of load st

47、ep, prior to going to next load.7.5 Continue test by applying increasingly higher steppedloadings corresponding to approximately 10 % of the finaldesign wind pressure until the wall assembly fails. Steppedloading increments shall be held for one minute, and loadsfrom force gage recorded at beginning

48、 of load step and at endof load step immediately prior to going to next load. Often thespecimen may fail transitioning from one sustained load to thenext higher step loading increment.NOTE 8Once the next load increment is applied, it is common for theload to begin to slowly decrease, due to deformat

49、ion of thermal insulationboard and elongation of test hardware.NOTE 9For EIFS cladding applied directly to a masonry substrate,adhesion of the lamina to the foam or foam to the masonry may exceed thecapacity of the load cell and force gage. If during load application themaximum capacity of the load measurement device is approached, theload should be temporarily released and the measuring device removed toavoid damage to the unit. A decision should be made by the test specifierwhether to retain the specimen on the wall and re
