3、1. Scope1.1 This specification covers solvent cement for joiningacrylonitrile-butadiene styrene (ABS) plastic pipe and fittingsfor pressure and nonpressure systems.1.2 Recommendation for using solvent cement for joiningacrylonitrile-butadiene-styrene (ABS) plastic pipe and fittingsis given in Append

Test Methods7.1 The properties enumerated in this specification shal
23、l bedetermined in accordance with the following methods:7.1.1 ConditioningCondition the test specimens at 73.4 63.6F (23 6 2C) for not less than 40 h prior to test inaccordance with Procedure A of Practice D 618, for those testswhere conditioning is required.7.1.2 Test ConditionsConduct tests at 73.
24、4 6 3.6F (23 62C), unless otherwise specified in the test methods or in thisspecification.7.2 Viscosity:7.2.1 The samples for test shall be representative of thematerial under consideration. One sample for every batch shallbe tested in accordance with 7.2.2.7.2.2 Measure the viscosity in accordance
25、with Method B ofTest Methods D 1084, except that conditioning to temperatureequilibrium only is required. For qualification purposes, use aModel RVF viscometer, a speed of 10 r/min, and the spindlethat, by trial, gives the closest reading to center range of scalefor the cement being tested. Other sp
26、eeds are used forqualification purposes.7.3 Total Solids:7.3.1 Apparatus:7.3.1.1 Ointment TinsStyle No. 12, 1 oz (30 mL) allmetal.7.3.1.2 Vacuum Oven.57.3.1.3 Desiccator.7.3.1.4 Analytical Balance.7.3.2 ProcedureStir the sample thoroughly with a spatulabefore weighing. Weigh 3.0 6 0.5 g of the sampl
27、e into a taredointment tin. Place tin into the vacuum oven and heat at 248F(120C) for 45 min. Vacuum must be continually in operationto draw off flammable solvents and should be maintained at 0.6in. Hg (15 mm Hg) minimum. Remove the tin from the ovenand cap immediately. Place in a desiccator until c
28、ooled to roomtemperature. Weigh the tin and dried sample to the nearest0.015 grains (1 mg).NOTE 3This material is usually nonhomogeneous and shall be thor-oughly stirred before weighing. The weighing shall also be accomplishedquickly to avoid loss of solvent by volatization.7.3.3 The use of a vacuum
29、 oven is mandatory for drying thespecimen because it has no exposed heating surface nor anopen flame, thus avoiding the danger of flashing. The oven alsoprovides an open vacuum to exhaust solvent fumes.7.3.4 The specimen shall be left in the oven for 45 min andno longer. Specimens left in for1hormor
30、e show a definiteincrease in weight.7.3.5 CalculationCalculate the percentage total solids,TS, as follows:TS,%=(B A)/(C A) 3 100where:A = weight of ointment tin,B = weight of tin and specimen after drying, andC = weight of tin and specimen before drying.7.3.6 PrecisionDuplicate samples shall be test
31、ed for bestresults. Duplicate results obtained by the same analyst, on thesame material, on the same day, in the same laboratory aresuspect if they differ by more than 0.52 % absolute. Thisprocedure has a standard deviation of 0.13.7.4 Lap Shear Strength (Qualification Tests):7.4.1 Number of Specime
32、nsA minimum of seven speci-mens shall be tested for the requirement specified in 6.5.7.4.2 Cut sections 1 by 1 in. (25 by 25 mm) and 1 by 2 in.(25 by 50 mm) from 0.25-in. (6-mm) thick ABS sheets. Onesection of each size is required for each specimen (Fig. 1).7.4.3 Clean the surfaces to be adhered wi
33、th a cloth damp-ened with methyl ethyl ketone (MEK).NOTE 4The cleaning of the surface with an abusive amount of MEKmay affect the performance of the test. Tests should be conducted todetermine if this is significant.5Labline Duo-Vac vacuum oven, or equivalent, has been found satisfactory forthis pur

(25 by 25-mm) sheet section and to thecenter ofa1by2-in. (25 by 50-mm) sheet section.7.4.5 Assemble these sections immediately and rotate the 1by 1-i
35、n. (25 by 25-mm) section 180 on the 1 by 2-in. (25 by50-mm) section within 5 s using light hand pressure (approxi-mately12 lbf (2 N).7.4.6 Place the assembled test specimen on a clean, levelsurface, by using the 1 by 2-in. (25 by 50-mm) section as abase. After 30 s, place a 4.4-lb (2-kg) weight on t
36、he testspecimen for a period of 3 min, then remove.7.4.7 Store the assembled test specimens at 73.4 6 3.6F(23 6 2C) for 48 to 50 h and test them in a holding fixturesimilar to that shown in Fig. 2.7.4.8 Place the specimen in the holding fixture and adjustthe screws to bring the sample to a vertical
37、position with theface of the 2-in. (50-mm) specimen in contact with the test jigas shown in Fig. 2 (Note 5). Back off the screw in contact withthe 2-in. specimen slightly, and insert a 0.001-in. (0.02-mm)shim between the screw plate and the specimen. Then bring thebearing plate of the test machine i
38、nto contact with the top of the2-in. specimen, using care to ensure that the plate is on ahorizontal plane.7.4.9 Apply the compressive shear at a speed of 0.05 in.(1.25 mm)/min. Express the results in megapascals (or pounds-force per square inch).NOTE 5Alternative jigs may be used if they can be sho
