17、ied.4. Materials and Manufacture4.1 The solvent cement shall be a solution of the base PVC resin used to make Class 12454-B poly(vinyl chloride) molding orextrusion compound as defined in Specification D1784.4.2 When rework material is used, the manufacturer shall use only his own clean rework mater

18、ial that is compatible with virginmaterial and produces a cement that meets the requirements of this specification.4.3 The cement shall be free-flowing and shall not contain lumps, macroscopic undissolved particles, or any foreign matter thatwill adversely affect the ultimate joint strength or chemi

19、cal resistance of the cement.4.4 The cement shall show no gelation. It shall show no stratification or separation that cannot be removed by stirring orshaking.4.5 When inert fillers are added, the resulting cement shall meet all requirements of this specification.4.6 The particular solvent system to

20、 be used in the formulation of this solvent cement is not specified, since it is recognized thata number of adequate solvent systems for PVC exist. Solvent systems consisting of blends of tetrahydrofuran and cyclohexanonehave been found to make cements that are acceptable under the requirements of t

21、his specification.NOTE 1It is recommended that solvent cements made to this specification not be orange since that color is recommended for use with CPVC solventcement under Specification F493.5. Requirements5.1 Resin ContentThe PVC resin content shall be 10 % minimum when tested in accordance with

22、6.1.5.2 DissolutionThe cement shall be capable of dissolving an additional 3 % by weight of PVC 12454-B compound (eitherpowder or granular) or the equivalent PVC resin at 73.4 6 3.6F (23 6 2C) without evidence of gelation.5.3 ViscosityCements are classified as regular-, medium-, or heavy-bodied type

23、s, based on their minimum viscosity whentested in accordance with 6.1.1.5.3.1 Regular-bodied cements shall have a minimum viscosity of 90 cP (90 mPas).5.3.2 Medium-bodied cements shall have a minimum viscosity of 500 cP (500 mPas).5.3.3 Heavy-bodied cements shall have a minimum viscosity of 1600 cP

24、(1600 mPas).NOTE 2Refer to Appendix X1 for guidelines in selecting PVC solvent cements for joining different pipe sizes.5.4 Lap Shear StrengthThe minimum average lap shear strength, when tested in accordance with 6.3.2, shall be 250 psi (1.7MPa) after a 2-h curing time, 500 psi (3.4 MPa) after a 16-

25、h curing time, and 900 psi (6.2 MPa) after a 72-h curing time.NOTE 3These values should not be used for designing piping joints.5.5 Hydrostatic Burst StrengthThe minimum average hydrostatic burst strength, when tested in accordance with 6.3.3, shallbe 400 psi (2.8 MPa) after a 2-h curing time.6. Tes

26、t Methods6.1 Solids Content:6.1.1 Apparatus:6.1.1.1 Ointment Tins (Style No. 12, 1-oz (30-mL), all metal).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 thoroughly with a spatula before weighing (Note 4). Weigh 3.0 6 0.5 g of the sample to t

27、he nearest 1mg into a tared ointment tin. Place tin into the vacuum oven (Note 5), and heat at 248F (120C) for 45 min +15, 0 min. Discardspecimens left in for more than 1 h. The vacuum must be continually in operation to draw off flammable solvents and shall bemaintained at 15 mm Hg minimum. Remove

28、the tin from the oven and place in a desiccator until cooled to room temperature.Weigh the tin and dried sample to the nearest 1 mg.NOTE 4This material is usually nonhomogeneous and shall be thoroughly stirred before weighing. The weighing shall also be accomplished quicklyto avoid loss of solvent b

29、y volatilization.NOTE 5The use of a vacuum oven is mandatory for drying the specimen, because this oven has neither an exposed heating surface nor an open flame,thus avoiding the danger of flashing. The oven also provides an open vacuum to exhaust solvent fumes.D2564 1226.1.2.2 After weighing, disso

30、lve most of the dried sample by adding 15 mL of tetrahydrofuran (THF) to the sample in theointment tin and stirring with a glass rod for 15 min. Collect the liquid decanted from this step, plus the liquid from the next twosteps. Dissolve the remainder with a second addition of 15 mL of THF, followed

31、 by a third addition of 5 mL of THF to rinse theointment tin. Centrifuge the entire volume at 20 000 r/min for 15 min. Discard the supernatant liquid. Add 15 mL of THF to thetube, mix thoroughly, and transfer the tube contents to the ointment tin. Use 2 mL more of THF to wash down the tube, and pour

32、into the ointment tin. Evaporate off the THF in the vacuum oven at 248F (120C) for 45 min. Cool in desiccator, weigh the tinto the nearest 1 mg, and calculate the percent of inert filler present in the cement.6.1.3 CalculationCalculate the percentage of PVC resin as follows:Resin,%5B 2A 2D!/C 2A!# 3

33、100 (1)where:A = weight of ointment tin,B = weight of tin and specimen after drying,C = weight of tin and specimen before drying, andD = weight of inert filler, if present.NOTE 6Other methods for determination of resin and inert filler content may be used provided the results of the alternative meth

34、od are as accurateand consistent as the above method.6.2 ViscosityMeasure the viscosity in accordance with Method B of Test Methods D1084, except that conditioning totemperature equilibrium only is required. For qualification purposes, use a Model RVF viscometer, a speed of 10 r/min, and thespindle

35、that, by trial, gives the closest reading to center range of scale for the cement being tested. Other speeds are also used forquality control purposes.6.3 Bond Strength:6.3.1 Number of SpecimensA minimum of seven specimens shall be tested for the lap shear strength test (see 5.4). A minimumof five s

36、pecimens shall be tested for the hydrostatic burst stength test (see 5.4).6.3.2 Lap Shear Strength:6.3.2.1 Cut 1 by 1-in. (25 by 25-mm) and 1 by 2-in. (25 by 50-mm) sections from 14-in. (6-mm) thick sheet made from Class12454-B PVC. One section of each size is required for each test specimen (Fig. 1

37、).6.3.2.2 Clean the surfaces to be adhered with a cloth dampened with methyl ethyl ketone (MEK).6.3.2.3 Using a 1-in. (25-mm) bristle brush, apply a thin layer of cement to the complete surface of a 1 by 1-in. (25 by 25-mm)sheet section and to the center of a 1 by 2-in. (25 by 50-mm) sheet section.6

38、.3.2.4 Assemble these sections immediately and rotate the 1 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 (approximately 0.5 lb (2 N).6.3.2.5 Place the assembled test specimen on a clean, level surface using the 1 by 2-in. (25 by 50-

39、mm) section as a base. After30 s, place a 2-kg weight on the test specimen for a period of 3 min, 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 immediately in a holdingfixture similar to that shown in Fig. 2. The shear speed shall be

40、0.05 in. (1.25 mm)/min. Express the results in pounds per squareinch (or megapascals).6.3.2.7 Disregard the lowest and highest value for the calculation of the average lap shear strength.6.3.3 Hydrostatic Burst Strength:6.3.3.1 Use 2-in. (50-mm) PVC Schedule 80 pipe meeting the requirements of Speci

41、fication D1785 and PVC Schedule 80couplings meeting the requirements of Specification D2467, except that the socket depth shall be 1.5 in. (38 mm). The dimensionsof the pipe and fitting socket shall be such that the pipe will enter the socket from one third to two thirds of the full socket depthdry

The pipe must be fully bottomed in the fitting socket.FIG. 1 Compression Shear SpecimenD2564 123NOTE 7Do not apply cleaner or primer since the

43、purpose of the test is to evaluate the cement, alone.6.3.3.3 Close the ends of the test specimens with suitable end closures for pressure testing.6.3.3.4 Store the specimens at 73.4 6 3.6F (23 6 2C) for 2 h 6 5 min; then test immediately.6.3.3.5 Increase the internal hydrostatic pressure at the rate

44、 of 200 psi (1.4 MPa)/min 6 10 % until failure occurs.7. Retest and Rejection7.1 If the results of any test(s) do not meet the requirements of this specification, the test(s) shall be conducted again only byagreement between the purchaser and the seller. Under such agreement, minimum requirements sh

45、all not be lowered, nor testsomitted, substituted, changed, or modified, nor shall specification limits be changed.
