Thoroughly stirone-component materials before using. Mix two-componentcompounds in the ratio recommended by
11、the manufacturer. Ifrequired by the manufacturer, mix each component prior to thefinal mix.9.

14、crosswise in thecenter of the 152 mm (6 in.) length to a depth of 6 mm (14 in.),as shown in Fig. 1.NOTE 1Mortar substrates must be prepared according to GuideC 1375.9.1.2 Measure the thickness of each block to the nearest0.025 mm (0.001 in.) on each side of the center notch, usingvernier calipers. M
15、ark the location where the measurementswere taken for future use. Record these values.9.1.3 Mark the edge of each slab along the 152 mm (6 in.)length so that the bench marks are 51 mm (2 in.) apart andapproximately 25 mm (1 in.) on each side of the center cut asshown in Fig. 1.9.1.4 Apply masking ta
16、pe across the ends of the uncut 76 by152 mm (3 by 6 in.) faces of the slabs, leaving an exposed 76by 102 mm (3 by 4 in.) area on each where the membrane maybe applied.9.1.5 For self-leveling membrane materials, lay the slabs ona bed of sand and level them.NOTE 2For self-leveling membranes, apply 50
17、mm (1 in.) widemasking tape around the slab perimeter. The tape should protrude abovethe slab surface on all four sides to form a dam.9.1.6 Apply sufficient membrane material to yield a dry filmthickness of 1.52 6 0.13 mm (60 6 5 mils) to the exposed areaon the slab. Check the membrane thickness wit
18、h a wet filmgage. The film thickness may be built up in multiple coats ifFIG. 1 Test Block for Testing Extensibility After Heat AgingC1522052specified by the manufacturer. Allow the three specimens tocure for 14 days at standard conditions (see 8.1).NOTE 3Prior to application, the non-volatile conte
19、nt or applicationrate must be known. Perform Test Method C 1250 to determine nonvola-tile content or contact the manufacturer for required information.NOTE 4An alternative thickness can be tested and must be reported inthe Test Report.9.1.7 Place the test assemblies in a forced-draft oven for 14days
20、 at 70 6 2C (158 6 3.6F). Remove the test assembliesandletcool1hatstandard conditions. Remove the maskingtape.9.1.8 Using vernier calipers, carefully measure the thicknessof the substrate-membrane composite at the locations previ-ously measured and marked. Measure to the nearest 0.025 mm(0.001 in.).
21、 Record these measurements.9.1.9 Place the test assemblies on a release paper coveredwooden board approximately 152 by 305 mm (6 by 12 in.) withthe membrane side face down. Restrain the test blocks byblocking the ends with blocks of wood nailed to the base boardto prevent the test blocks from flying
22、 apart. Insert a steel wedgeinto the cut and hit with a hammer no harder than necessary tocause the test block to crack along the cut. Be careful, asexcessive force will crack the sample.9.1.10 Handling very carefully to prevent tearing the mem-brane, place each of the specimens in turn in the jaws
23、of thetesting machine and pull it in a direction perpendicular to thebreak, at a separation rate of 12.7 mm (0.5 in.)/min., until thedistance between the benchmarks is 57.2 mm (2.25 in.). Stopthe machine and immediately examine the films for any breaksor cracks.10. Test Report10.1 Number and length
