18、 1).NOTE 4Five test specimen 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 specia
19、l careto strike off the 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 m
20、ust be listed in the 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
21、of 50.8 mm (2.0 in.) 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
22、 0.8 mm (0.03125in.) the actual minimum length (Dimension A) and minimumwidth (Dimension B), in millimetres (inches) as shown in Fig.1.8.1.3 Record the tensile load, C, (see Note 5), newtons (lbs)at 10, 25, 50, and 100 %, and at maximum elongation (see Note6). Measure and record percent cohesive fai
