Scope1.1 This test method covers a laboratory procedure forquantitatively measuring the tensile adhesion proper
3、ties ofstructural sealants, hereinafter referred to as the “sealant”.1.2 The values stated in SI (metric) units are to be regardedas the standard. The inch-pound values given in parentheses areprovided for information only.1.3 This standard does not purport to address all of thesafety concerns, if a

Significance and Use4.1 Frequently, glass or other glazing or panel materials arestructurally adhered with a sealant to a metal framing system.The sealants used for these
7、applications are designed to providea structural link between the glazing or panel and the framingsystem.4.2 Although this test method is conducted at one prescribedenvironmental condition, other environmental conditions andduration cycles can be employed.5.

15、 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, United States.6.1.1 Prior to assembly, wipe the substrates with a clean,dry, lint-free cloth, then thoroughly clean with a solutionappropriate for the substrate material. Prior to evaporation ofthe cleaning solution, wipe the substra
16、tes dry with a clean,lint-free cloth.NOTE 3The precision and bias statement is based on glass substrateswith a recommended cleaning solution of a 50 to 50 ratio isopropanol andwater.6.1.2 Apply recommended primer, if required. Then, con-struct the test specimen assemblies by forming a sealant cavity
17、12.7 by 12.7 by 50.8 mm (0.50 by 0.50 by 2.0 in.) between twosubstrate panels (see Fig. 1) with the aid of appropriate spacers.6.2 Preparation of Test Assemblies:6.2.1 Prepare a set of five test specimen assemblies for eachsealant and substrate combination being tested (see Fig. 1).NOTE 4Five test s
18、pecimen assemblies should be prepared for eachadditional environmental condition being evaluated.6.2.2 Fill each set of five assemblies with the sealant beingtested. Immediately tool the sealant surface to ensure completefilling and wetting of the substrate surfaces. Take special careto strike off t
19、he sealant flush with the substrate.6.3 LabelingEach of the five specimens of each set shouldbe individually identified.7. Conditioning7.1 Cure the specimens for 21 days at 23C (3.6F) and 506 6 % relative humidity (standard conditions). Any deviationsfrom the curing conditions must be listed in the
20、report.7.2 Remove all spacer sections from the specimens. Ifdesired, spacers may be removed prior to the end of the 21 daycure. If removed early, note this in the report.8. Procedure8.1 Testing:8.1.1 Pull all specimens on the tensile test machine atstandard conditions at a rate of 50.8 mm (2.0 in.)
21、per minute.If an analog chart recording device is being used, the chartspeed should be a minimum of 127 mm (5.0 in.) per minute(508 mm (20.0 in.) per minute is preferred) to allow for a moreaccurate reading of force at specific elongations.8.1.2 Measure and record to the nearest 0.8 mm (0.03125in.)

Measure and record percent cohesive failure.NOTE 5If the sub
23、strate breaks, disregard the value at which it breaks.Other values obtained prior to breakage are acceptable.NOTE 6Calculate the maximum elongation from the recording chartvalue at the point of maximum load.8.2 ObservationsObserve the specimens and record anyobvious air bubbles trapped in the sealan

30、was no bias reported in the test results when both acidand neutral curing structural silicone sealants were evaluatedafter both room temperature conditioning and after condition-ing seven days immersed in water prior to testing at roomtemperature.4Supporting data are available from ASTM Headquarters
