6. Test Methods 6.1 Specimen Curing- Cure all specimens at standard laboratory conditions for 24士4 h as specified in Test Methods D 5329 prior to beginning any testing 6.2 Cone Penetralion, Non-immersed- -Use Test Method D 5329 for cone penetration, non-immersed. 6.3 Flow- -Use Test Method D 5329 for flow. 6.3.1 Test the specimen at 140士2F(60士l’C)for5 h. 6.4 Bond, Non-immersed- Use Test Method D 5329 for bond, non-immersed. 6.4.1 Prepare six 1 by 2 by 3 in. concrete blocks according to Practice D 1985. 6.4.2 After final scrubbing and blotting specified in Test Methods D 5329, air dry the blocks standing on their I by 2 in. ends at standard laboratory conditions for 24土2 b. There shall be no free moisture on any of the block surfaces when bond specimens are prepared. If necessary, blotting may be done with an oil-free, clean, soft absorbent cloth or paper. 6.4.3 Immediately after conditioning assemble the blocks with spacers specified in Test Methods D 5329 so the opening between the blocks forms a cured sealant block which is 1 .000士0.005 in. wide. 6.4.4 After cnditioning, trim off the excess material and condition the specimens at0土2F(- 17.8 土1*C) for not less than 4 b, then immediately extend / in. at 0.125 in./b. This results in a 50 % extension. 6.4.5 Recompress and re extend for four additional cyclcs for 2 total of fve cycles as dcscribed in Test Methods D 5329. The five roquired cycles shall be completed within a 7 day period. 7. Packnging aod Marking 7.1 The sealing compound shall be delivered in the manufacturer’s original contaipers.
