Summary of Test Method4.1 Specimens are tested by applying tensile loads normal tothe plane of the system in a controlled environment todetermine the tensile adhesion of the system or individualcomponents

8、of the system, of both.5. Significance and Use5.1 Maintenance of adequate tensile adhesion of EIFScomponents to each other, and to the substrate are essential forlong term performance of the system.5.2 The tensile-adhesion properties obtained by this testmethod are not purported to be representative

9、 of wind load orother structural and moisture related properties of the EIFSwall assembly. Tensile-adhesion properties using this testmethod are used as one of the factors in evaluating substratesand to compare adhesives.6. Apparatus6.1 Tensile Test Machine, capable of producing a tensileload on the

10、 test specimen at a constant cross-head rate of 1.5mm/min (0.05 in./min).6.2 Load Measuring Device, calibrated according to Prac-tice E4, the test machine load measuring device shall becapable of measuring the load to an accuracy of 61 % of themaximum load applied to the test specimen.6.3 Loading Fi

11、xtures The loading fixtures shall be self-aligning and shall not apply eccentric loads.

15、6 5F) and 50 6 5%relative humidity.6.5 Containers, corrosion resistant containers of sufficientsize to hold specimens.7. Sample Preparation7.1 Prepare one sample for each test condition described inSections 9, 10, and 11. Samples shall be not less than 150 by200 mm (6 by 8 in.) in size, such that, s

16、ix test specimens nosmaller than 50 by 50 mm (2 by 2 in.) can be cut from eachsample after the specified sample conditioning. Samples maybe cut from larger sheets for ease of system fabrication.NOTE 1As required above, test specimen size shall not be smallerthan 50 by 50 mm (2 by 2 in.). However, as

17、 test specimen size increases,axial loading eccentricities become greater and can compromise theaccuracy of the test results. To limit the effect of eccentricities, maximumtest sample size should be limited to about 76 by 76 mm (3 by 3 in.).7.2 Apply the adhesive in a uniform, continuous layer, such

18、that the measured tensile load is representative of a fullybonded 50 by 50 mm (2 by 2 in.) test specimen. Apply thespecified amount of adhesive. Smooth-out the adhesive using aflat trowel to ensure a uniform, continuous layer.7.3 Samples conditioned wet under Section 11 or exposed tooptional environ

19、mental conditioning under Section 9 mayoptionally have their back-sides protected from moisture usingminimum 0.4-mm (0.015-in.)-thick aluminum foil bent half thedistance up each edge of the sample. Following application ofthe aluminum foil, all four sample edges shall be dipped in hotwax to protect

20、the edge from ingress of moisture.7.4 For system testing, each sample shall consist of asubstrate, adhesive, 25 mm (1 in.)-thick insulation board,reinforced base coat, primer (if used) and a finish coat.7.5 For testing the interface between the substrate andadhesive, each sample shall consist of a s

21、ubstrate and adhesiveonly.7.6 For testing the interface between the adhesive andinsulation board, each sample shall consist of an adhesive and25 mm (1 in.)-thick insulation board.7.7 For testing the interface between the base coat andinsulation board, each sample shall consist of 25 mm (1in.)-thick

22、insulation board and reinforced base coat.7.8 For testing the interface between the base coat, primer(if used) and finish coat, each sample shall consist of thereinforced base coat and finish coat.NOTE 2For mechanically attached EIF Systems, tensile-adhesionperformance is only required for the inter

23、face between the reinforced basecoat and finish coat.8. Sample Curing8.1 Allow samples to cure a minimum of seven days (28days for samples containing hydraulic cement) at a constant 236 3C (73 6 5F) and 50 6 5 % relative humidity unlessotherwise specified.9. Specified Sample Exposure (When Specified

24、)9.1 Often it is desired to determine the effects of a specifiedsample exposure condition on tensile-adhesion strength. Thetensile-adhesion test shall be conducted on companion samplesbefore and after each exposure period.NOTE 3Depending on project objectives, it may be desired todetermine retention

25、 of tensile-adhesion strength after extended wettingperiods, freeze-thaw cycles, accelerated aging exposure, acceleratedweathering cycles, other simulated static or cyclic environmental exposureconditions, conditions simulating system breach (that is, cracking), oractual field exposure.9.2 After the

26、 specified exposure period, condition samplesprior to testing dry or wet according to Sections 10 or 11,respectively.10. Procedure ADry Conditioning and Testing ofSpecimens10.1 Dry Conditioning Condition all samples prior totesting in a dry state. Condition samples for seven days at aconstant 2363C

27、(7365F) and 5065 % relative humidity.Dry conditioning may be omitted for new samples that havebeen cured according to Section 8.10.2 Test Specimen PreparationPrepare six 50 by 50 mm(2 by 2 in.) test specimens from each 150 by 200 mm (6 by 8in.) sample by sawing with a dry saw blade capable ofdry-cut

28、ting the sample with negligible test specimen distur-bance. Samples damaged during preparation shall not be tested.10.3 Test Procedure Attach the loading fixtures to the testspecimens. For test specimens bonded to loading fixtures, usea paste consistency epoxy to avoid penetration of epoxy intothe t

29、est plane (see Note 4). Take care during epoxy applicationsuch that epoxy does not squeeze-out from between fixturesand coat specimen sides, thereby potentially increasing themeasured tensile-adhesion load.NOTE 4EPOWELD Extra Fast Setting Epoxy (Parts A and B), Part A(Reorder No. 04001-A) and Part B

30、 (Reorder No. 04001-B)4has givensuitable results when used in accordance with the manufacturers instruc-tions.After use, place loading fixtures in oven at 204C (400F) for1hforeasy cleaning with scraper.10.3.1 Place loading fixtures in position without eccentricloading on the tensile-test machine.10.

31、3.2 Apply a tensile load at a constant rate of cross-headmovement such that a maximum load will occur between 3 and6 min.NOTE 5It has been found that a cross-head movement rate of 25m/s(0.05 in./min.) is satisfactory to achieve maximum load in the appropriateamount of time for a 25-mm (1-in.)-thick

32、test specimen.10.3.3 Record the tensile-adhesion load at failure and theobserved failure mode of all test specimens.10.3.4 After testing, measure the actual thicknesses of eachcomponent layer for each specimen to the nearest 0.1 mm(0.005 in.)

Samples damaged duringpreparation shall not be tested.11.3 Test Procedure Attach the loading fixtures to the testspecimens and place specimens into a sealed plastic bag to betested within 2 h. For test specimens bonded to loadingfixtures, use an epoxy sp

38、ecifically manufactured for bonding towet surfaces (see Note 7). Take care during epoxy applicationsuch that epoxy does not squeeze-out from between fixturesand coat specimen sides, thereby potentially increasing themeasured tensile-adhesion load.NOTE 7WET SURFACE PATCHING EPOXY, Part A (Reorder No.

39、04003-A) and Part B (Reorder No. 04003-B)4has given suitable resultswhen used in accordance with the manufacturers instructions.
