3、ent of Defense.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
4、given in Appendix X1. Satisfactory joining of pipe andfittings cannot be made in the presence of water, as waterdestroys the bonding ability of solvent cement; therefore, allmaterials must be dry for satisfactory joining.1.3 The text of this specification references notes, footnotes,and appendixes w

Test Methods7.1 The properties enumerated in this specification shall 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
24、40 h prior to test inaccordance with Procedure A of Practice D618, for those testswhere conditioning is required.7.1.2 Test ConditionsConduct tests at 73.4 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 repres
25、entative 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 with Method B ofTest Methods D1084, except that conditioning to temperatureequilibrium only is required. For qualification purposes, use aModel RV
26、F 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 speeds 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 Ov
27、en.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 sample 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 fl
28、ammable 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 cooled to roomtemperature. Weigh the tin and dried sample to the nearest0.015 grains (1 mg).NOTE 3This material is usually nonhomogeneous and shall
29、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 oven is mandatory for drying thespecimen because it has no exposed heating surface nor anopen flame, thus avoiding the danger of flashing. The ove
30、n 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 for1hormore 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
31、 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 tested for bestresults. Duplicate results obtained by the same analyst, on thesame material, on the same day, in the same laboratory aresuspect if they
32、 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 SpecimensA 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
33、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 with a cloth damp-ened with methyl ethyl ketone (MEK).5Labline Duo-Vac vacuum oven, or equivalent, has been found satisfactory forthis purpose.D2235
34、04 (2011)2NOTE 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.7.4.4 Using a 1-in. (25-mm) natural bristle brush, apply twolayers of cement in immediate succession to the completesurface of
35、a1by1-in. (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-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-mately12 lbf (2 N).7.4.6 Pl
36、ace 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 the 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 t
37、hem 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 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 wi
38、ththe 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 into 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
39、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 shown to beequivalent.7.4.10 Disregard the lowest and highest value for thecalculation of the average lap shear strength.8.
