Significance and Use4.1 The purpose of this test method is to assess the installation adequacy and the overall effects of service-related deterioration(moisture, etc.) on the EIFS wall assembly as opposed to small localized

20、 areas of degradation. Resistance to pull testing asdetermined by this test is used as one of the factors in evaluating the EIFS assembly on a specific project. The values obtainedby this test method are not purported to be representative of the actual wind load capacity or other structural properti

21、es of a specificEIFS clad wall installation, but may be helpful in assessing such load capacities.4.2 Since this test is used for field evaluation of existing facilities, load results obtained from this test must be interpreted basedon sound engineering practice, applicable building regulations, and

22、 codes having jurisdiction. It is the discretion of the test specifierto directly utilize the results derived by this test method, or else to utilize the test results with an appropriate factor of safety toobtain acceptable working loads for each project.4.3 This method is intended for use on test s

23、pecimens occurring or installed on existing buildings. The loss of outward windload resistance of an EIFS wall assembly after exposure to moisture and other weather conditions may compromise the ability ofthe cladding or other wall components to perform adequately in place. This test method does not

24、 provide any means by which thetest results may be generalized to the larger wall area. Such efforts should be based on experience and engineering judgement.4.4 The manner in which the test load is applied may affect the load capacity obtained from using this standard. test method.A discussion of va

25、rious load application techniques and their effects is given in Appendix X1.5. Apparatus5.1 Electronic rebar locator or metal detector sensitive enough to locate metal studs or fasteners of the underlying structuralframing through the EIFS assembly.5.2 Pull test frame fabricated from metal or wood,

26、as required, with capability of applying a concentric pull force to the testmodule and distributing reaction force on adjacent wall components. Pull test frame shall be provided, as a minimum, with aworm-gear winch and a nylon strap or wire rope capable of applying load to test module in controlled

27、manner with incrementallyincreasing load intensities. Alternative means of applying a consistent load using electro-servo motors or hydraulic units are alsoacceptable, provided they are capable of applying consistent, uniform load. It is intended that the pull test frame be easilytransportable and r

28、elocated so that it can be readily used on saw-horses, scaffolding, or a swing-stage.An example of an acceptabletest frame is shown in Fig. 1.5.3 Electronic load cell with digital force gage having a capacity of at least 4450 N, (1000 lbf.),N 1000 lbf., and an accuracyof 62 %.5.4 610 mm by 610 mm (2

For testing purposes, temporarily fasten the bolting panel at each adhered bondingplate in succession with appropriate hardware, immediately prior to testing.NOTE 2Screw hole locations for both the bonding panels and the bolting panel must align for proper attachmen

Test Specimen6.1 Sampling locations and number of specimens shall be specified by the user. Primarily, this test method is intended

33、toimplement qualitative evaluation techniques that lead to an accumulation of information in an orderly and efficient manner inaccordance with procedures prescribed within Guide E2128. If a hybrid method using a combination of qualitative and quantitativeevaluation techniques is desired by the test

34、specifier, then a random number generator method may be utilized to establish locationsE2359/E2359M 132FIG. 1 Pull Test FrameE2359/E2359M 133of test specimens required to represent the entire building population. Include additional test specimens at locations of suspectedor potential problems, such

35、as below window corners, at wall base, and so forth.NOTE 3For the hybrid method using a combination of qualitative and quantitative evaluation techniques, a selection method based on Practice D3665may be utilized for this purpose.6.2 Locate metal studs within wall system (or else fastener heads at w

If foam fasteners are present or suspected within the EIFS clad wal

Procedure7.1 Obtain information regarding the cladding assembly design wind pressure (DWP) utilized during original construction ofthe building, or else otherwise determine an appropriate cladding DWP for comparative purposes using local building c

Establish initial load at approximately ten percent (10 %) of cladding design wind pressure.7.2 Align the bolting panel, with appropriate pull hardware inserted through center hole, onto the previously adhered bondingpanel and securely fasten bolting panel

See Fig. 6.NOTE 7Use saw-horse, scaffolding deck, or swing-stage rails to temporarily support pull test frame until sufficient load is achie

47、ved to make test frameself-supporting. Be prepared to re-establish temporary support at end of test, or in case of sudden failure of test specimen.7.4 Apply previously determined initial load to test module as required to hold pull test frame in place and hold for one minute.Record load from force g

S

49、tepped loading increments shall be held for one minute, and loads from force gagerecorded at beginning of load step and at end of load step immediately prior to going to next load. Often the specimen may failtransitioning from one sustained load to the next higher step loading increment.NOTE 8Once the next load increment is applied, it is common for the load to begin to slowly decrease, due to deformation of thermal insulation boardand elongation of test hardware.NOTE 9For EIFS cladding applied directly to a masonry s
