16、endations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.14. Materials and Manufacture4.1 The solvent cement shall be a solution of the base PVCresin used to make Class 12454-B poly(vinyl chloride) mold-ing or extrusion compound as defined in Specification D1784.4
17、.2 When rework material is used, the manufacturer shalluse only his own clean rework material that is compatible withvirgin material and produces a cement that meets the require-ments of this specification.4.3 The cement shall be free-flowing and shall not containlumps, macroscopic undissolved parti
18、cles, or any foreignmatter that will adversely affect the 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 When inert fillers are added, the resulting cemen
19、t shallmeet all requirements of this specification.4.6 The particular solvent system to be used in the formu-lation of this solvent cement is not specified, since it isrecognized that a number of adequate solvent systems for PVCexist. Solvent systems consisting of blends of tetrahydrofuranand cycloh
20、exanone have been found to make cements that areacceptable under the requirements of this specification.NOTE 1It is recommended that solvent cements made to this speci-fication not be orange since that color is recommended for use with CPVCsolvent cement under Specification F493.5. Requirements5.1 R
21、esin ContentThe PVC resin content shall be 10 %minimum when tested in accordance with 6.1.5.2 DissolutionThe cement shall be capable of dissolvingan additional 3 % by weight of PVC 12454-B compound(either powder or granular) or the equivalent PVC resin at 73.46 3.6 F (23 6 2 C) without evidence of g
22、elation.5.3 ViscosityCements are classified as regular-, medium-,or heavy-bodied types, based on their minimum viscosity whentested in accordance with 6.1.1.5.3.1 Regular-bodied cements shall have a minimum vis-cosity of 90 cP (90 mPas).5.3.2 Medium-bodied cements shall have a minimum vis-cosity of
23、500 cP (500 mPas).5.3.3 Heavy-bodied cements shall have a minimum viscos-ity of 1600 cP (1600 mPas).NOTE 2Refer to Appendix X1 for guidelines in selecting PVC solventcements for joining different pipe sizes.5.4 Lap Shear StrengthThe minimum average lap shearstrength, when tested in accordance with 6
24、.3.2, shall be 250 psi(1.7 MPa) after a 2-h curing time, 500 psi (3.4 MPa) after a16-h curing time, and 900 psi (6.2 MPa) after a 72-h curingtime.NOTE 3These values should not be used for designing piping joints.5.5 Hydrostatic Burst StrengthThe minimum average hy-drostatic burst strength, when test
25、ed in accordance with 6.3.3,shall be 400 psi (2.8 MPa) after a 2-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. Oven6.1.1.3 Analytical. Balance6.1.1.4 Centrifuge.6.1.2 Procedure:6.1.2.1 Stir the sample thor
26、oughly with a spatula beforeweighing (Note 4). Weigh 3.0 6 0.5 g of the sample to thenearest 1 mg into a tared ointment tin. Place tin into thevacuum oven (Note 5), and heat at 248 F (120 C) for 45 min+15, 0 min. Discard specimens left in for more than 1 h. Thevacuum must be continually in operation
27、 to draw off flammablesolvents and shall be maintained at 15 mm Hg minimum.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 bethoroughly stirred before wei
28、ghing. The weighing shall also be accom-plished quickly to avoid loss of solvent by volatilization.NOTE 5The use of a vacuum oven is mandatory for drying thespecimen, because this oven has neither an exposed heating surface nor anopen flame, thus avoiding the danger of flashing. The oven also provid
29、esan open vacuum to exhaust solvent fumes.6.1.2.2 After weighing, dissolve most of the dried sampleby adding 15 mLof tetrahydrofuran (THF) to the sample in theointment tin and stirring with a glass rod for 15 min. Collectthe liquid decanted from this step, plus the liquid from the nexttwo steps. Dis
30、solve the remainder with a second addition of 15mL of THF, followed by a third addition of 5 mL of THF torinse the ointment tin. Centrifuge the entire volume at 20 000r/min for 15 min. Discard the supernatant liquid.Add 15 mLofTHF to the tube, mix thoroughly, and transfer the tube contentsto the oin
31、tment tin. Use 2 mL more of THF to wash down thetube, and pour into the ointment tin. Evaporate off the THF inthe vacuum oven at 248 F (120 C) for 45 min. Cool indesiccator, weigh the tin to the nearest 1 mg, and calculate thepercent of inert filler present in the cement.6.1.3 CalculationCalculate t
32、he percentage of PVC resinas follows:Resin, % 5 B 2 A 2 D!/C 2 A!# 3100 (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 fil
33、lercontent may be used provided the results of the alternative method are asaccurate and consistent as the above method.6.2 ViscosityMeasure the viscosity in accordance withMethod B of Test Methods D1084, except that conditioning totemperature equilibrium only is required. For qualificationpurposes,
34、 use a Model 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 arealso used for quality control purposes.D2564 12 (2018)26.3 Bond Strength:6.3.1 Number of SpecimensA minimum of seven speci-m
35、ens shall be tested for the lap shear strength test (see 5.4).
