16、of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.16. Apparatus6.1 Tensile Test Machine, capable of producing a tensileload on the test specimen at a constant cross-head rate of 1.5mm/min 0.05 in./min.6.2 Load Me

17、asuring Device, calibrated according to Prac-tices 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 FixturesThe loading fixtures shall be self-aligning and shall not apply eccentric loa

18、ds. The loadingfixtures shall be a minimum of 12.0-mm 0.5-in. thick metalblocks to keep the bonded facings essentially flat under themaximum applied load. The size of the loading blocks shall benot less than the bonded area of the test specimen.6.4 Temperature Control ChamberA room or chambercapable

19、 of maintaining 23 6 3 C 75 6 5 F 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

20、 in. in size, such that, six 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 smaller than50 by 50 mm 2

21、 by 2 in. However, as test specimen size increases, axialloading eccentricities become greater and can compromise the accuracy ofthe test results. To limit the effect of eccentricities, maximum test samplesize should be limited to about 76 by 76 mm 3 by 3 in.7.2 Apply the adhesive in a uniform, cont

22、inuous layer, suchthat 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 to

23、optional environmental 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 hotw

24、ax to protect 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 co

25、nsist of a substrate 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 1-i

26、n.thick 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 t

27、he interface 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 3 C 73 6 5 F and 50 6 5 % relative humidity unlessotherwise specified.9. Specified Sample Exposure (When S

28、pecified)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 r

29、etention 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 A

30、fter the 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 ConditioningCondition all samples prior to test-ing in a dry state. Condition samples for seven days at aconsta

31、nt 23 6 3 C 73 6 5 F and 50 6 5 % relativehumidity. Dry conditioning may be omitted for new samplesthat have been cured according to Section 8.10.2 Test Specimen PreparationPrepare six 50 by 50 mm2 by 2 in. test specimens from each 150 by 200 mm 6 by 8in. sample by sawing with a dry saw blade capabl

32、e ofdry-cutting the sample with negligible test specimen distur-bance. Samples damaged during preparation shall not be tested.10.3 Test ProcedureAttach the loading fixtures to the testspecimens. For test specimens bonded to loading fixtures, usea paste consistency epoxy to avoid penetration of epoxy

33、 intothe test 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)

34、and Part B (Reorder No. 04001-B)4has givensuitable results when used in accordance with the manufacturers instruc-tions. After use, place loading fixtures in oven at 204 C 400 F for 1 hfor easy cleaning with scraper.4The sole source of supply of the apparatus known to the committee at this timeis Ha

40、ate thepotential for non-uniform absorption.11.2 Test Specimen PreparationRemove samples fromwet conditioning. Remove the protective aluminum foil (ifused).
