15、1 The solvent cement shall be a solution of Class12454-B, unplasticized poly(vinyl chloride) molding or extru-sion compound as classified in Specification D 1784,orequivalent PVC resin.4.2 Either virgin or clean rework material may be used,provided that the rework material is generated from the solv

16、entcement manufacturers own production, is compatible withvirgin material, and will produce a cement that meets therequirements of this specification.4.3 The cement shall be free-flowing and shall not containlumps, macroscopic undissolved particles, or any foreignmatter that will adversely affect th

17、e ultimate joint strength orchemical resistance of the cement.4.4 The cement shall show no gelation. It shall show nostratification or separation that cannot be removed by stirringor shaking.4.5 Inert fillers may be added, provided the resulting cementmeets all requirements of this specification.4.6

18、 The solvents used in the formulation of this solventcement shall consist of tetrahydrofuran (THF) in combinationwith cyclohexanone or methyl ethyl ketone (MEK), or both.NOTE 2It is recommended that solvent cements made to this speci-fication not be orange since that color is recommended for use wit

21、typefit (where a gap exists between the pipe and fitting socket).5.4 Lap Shear StrengthThe minimum average lap shearstrength when tested in accordance with 6.3.2 shall be 600 psi(4.1 MPa) after a 72-h curing time.5.5 Hydrostatic Burst StrengthThe minimum average hy-drostatic burst strength when test

22、ed in accordance with 6.3.3shall be 200 psi (1.4 MPa) after a 72-h curing time.6. Test Methods6.1 Solids Content:6.1.1 Apparatus:6.1.1.1 Ointment Tins (Style No. 12, 1-oz (30-mL), allmetal).6.1.1.2 Vacuum Oven.6.1.1.3 Analytical Balance.6.1.1.4 Centrifuge.6.1.2 Procedure:6.1.2.1 Stir the sample thor

23、oughly with a spatula beforeweighing (Note 4). Weight 3.0 6 0.5 g of the sample to thenearest 1 mg into a tared ointment tin. Place the tin into thevacuum oven (Note 5), and heat at 248F (120C) for 45 min+ 15, 0 min. Discard specimens left in for more than 1 h. Thevacuum must be continually in opera

24、tion to draw off flammablesolvents. Absolute pressure should not exceed 15 mm Hg.Remove the tin from the oven and place in a desiccator untilcooled to room temperature. Weigh the tin and dried sample tothe nearest 1 mg.NOTE 4This material is usually nonhomogeneous and shall be thor-oughly stirred be

25、fore weighing. The weighing shall also be accomplishedquickly to avoid loss of solvent by volatilization. Some vacuum ovensrequire a longer period of time than 15 min to reach 120C, even afterpreheating. It is recommended that the operator watch closely the timerequired to reach 120C and, by manipul

26、ation of the heat controlmechanism, minimize the amount of time required to reach 120C whilenot exceeding the required temperature.NOTE 5The use of a vacuum oven is mandatory for drying thespecimen. This oven has neither an exposed heating surface nor an openflame, thus avoiding the danger of flashi

27、ng. The oven also provides anopen vacuum to exhaust solvent fumes.6.1.2.2 After weighing, dissolve the dried sample in THFand determine quantitatively any inert fillers by means ofcentrifuging. Deduct the weight of the fillers determined fromthe weight of the dried sample prior to calculating the co

28、ntentof PVC resin in the cement.NOTE 6Dissolve most of the dried sample by adding 15 mL of THFto the sample in the ointment tin and stirring with a glass rod for 15 min.Dissolve the remainder with a second addition of 15 mL of THF, followedby a third addition of 5 mL of THF to rinse the ointment tin

29、. Centrifugethe entire volume at 20 000 r/min for 15 min. Discard the supernatantliquid. Add 15 mL of THF to the tube, mix thoroughly, and transfer thetube contents to the ointment tin. Use 2 mL more of THF to wash downthe tube, and pour into the ointment tin. Evaporate off the THF in thevacuum oven

30、 at 248F (120C) for 45 min. Cool in desiccator, weigh thetin to the nearest 1 mg, and calculate the percent of inert filler present inthe cement.6.1.3 CalculationCalculate the percentage of PVC resin,R, as follows:R,%5 B 2 A 2 D!/C 2 A!# 3 100where:A = weight of ointment tin,B = weight of tin and sp

31、ecimen after drying,C = weight of tin and specimen before drying, andD = weight of inert filler, if present.6.2 ViscosityMeasure the viscosity in accordance withMethod B of Test Methods D 1084 except that conditioning totemperature equilibrium only is required. For qualificationpurposes use a Model

32、RVF viscometer, a speed of 10 r/min,and the spindle that, by trial, gives the closest reading to centerrange of scale for the cement being tested. Other speeds may beused for quality control purposes.6.3 Bond Strength:6.3.1 Number of SpecimensA minimum of seven speci-mens shall be tested for the lap

33、 shear strength test (see 5.4). Aminimum of five specimens shall be tested for the hydrostaticburst strength test (see5.5).6.3.2 Lap Shear Strength:6.3.2.1 Each test specimen (Fig. 1) shall consist ofa1by1-in.

(25-mm) natural bristle brush, apply athin layer of cement to the complete surface ofa1by1-in. (25by 25-

35、mm) sheet section and to the center of a 1 by 2-in. (25by 50-mm) sheet section.6.3.2.4 Assemble these sections immediately and rotate the1 by 1-in. (25 by 25-mm) section 180 on the 1 by 2-in. (25 by50-mm) section, within 5 s, using light hand pressure (approxi-mately 0.5 lbf (2 N).6.3.2.5 Place the

36、assembled test specimen on a clean, levelsurface using the 1 by 2-in. (25 by 50-mm) section as a base.After 30 s, place a 4.4-lb (2-kg) weight on the test specimen fora period of 3 min, and then remove.6.3.2.6 Store the assembled test specimens at 73.4 6 3.6F(23 6 2C) for the specified time and test

37、 immediately in aholding fixture similar to that shown in Fig. 2. The shear speedshall be 0.05 in. (1.25 mm)/min. Express the results in poundsper square inch (or megapascals).6.3.2.7 Disregard the lowest and highest value for thecalculation of the average lap shear strength.6.3.3 Hydrostatic Burst
