A num

2、ber in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification covers the socket produced for s

3、ol-vent cement joints on both pressure and non-pressure IPS pipe.It also covers the testing of the joints on both pressure andnon-pressure pipe, and includes requirements for socketdimensions, burst pressure, and joint tightness tests of thesolvent cemented joints. The tests described are not intend

4、edfor routine quality control, but rather to evaluate the perfor-mance characteristics of the joint.NOTE 1On dual marked Schedule 40 DWV and potable water pipe,the socket bells must conform to the dimensional and physical require-ments for pressure socket bells.1.2 The text of this specification ref

Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specification.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parent

6、heses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.NOTE 2Changes in ground, water, or air temperature will produceexpansion or contraction forces in PVC piping, and these will result inlongitudinal shear stresses in the solvent cement

These stressesmust be considered in the design and operation of the system.NOTE 3See Practice D618 for information relating to this specifica-tion.1.4 The following safety hazards caveat pertains only to thetest method portion, Section 10, of this specification.

Under suchagreem

32、ent, minimum requirements shall not be lowered, nortests omitted, substituted, changed, or modified, nor shallspecification limits be changed.

33、ecimens8.1 Take at random a sample of the pipe with (bell) socketsufficient to determine conformance with this specification.8.1.1 The test specimens for any pressure test shall have atleast a part of the marking in their central sections. The centralsection is that portion of pipe which is at least

34、 one pipediameter away from an end closure.8.1.2 Dry Fit of JointManually insert a chamfered ordeburred pipe spigot into the socket (bell). There must be aninterference between the spigot and bell after inserting thespigot one third to two thirds of socket (bell) depth.9. Conditioning9.1 Condition t

35、he test specimens at 73.4 6 3.6F (23 62C) and 50 6 10 % relative humidity for not less than 40 hprior to test in accordance with Procedure A of Practice D618,for those tests requiring conditioning.10. Test Methods10.1 Test ConditionsConduct the tests in the StandardLaboratory Atmosphere of 73.4 6 3.

36、6F (23 6 2C) and 50 610 % relative humidity, unless otherwise specified in PracticeD618 or in this specification.10.2 Socket Joint AssemblyAssemble the socket joint perPractice D2855, and condition at 73.4F (23C) for a minimumof 48 h.10.3 Burst Pressure Test of Joint AssemblyDetermine theburst press

37、ure of one specimen in accordance with Test MethodD1599. The assembled socket (bell) joint shall be within themiddle 30 % of the overall specimen length. The time to failureof the specimen shall be between 60 and 70 s.10.4 Socket Joint Tightness TestSubject the assembly toan internal pressure of 25

38、psi (170 kPa) using water as the testmedium. Maintain this pressure for at least 1 h. There shall beno leakage.11. Marking and Quality Assurance11.1 When pipe, made in accordance with SpecificationsD1785, D2241, D2665 and F512, is marked with ASTMdesignation D2672, in addition to the pipe standard,

39、it affirmsthat the sockets (bell) were manufactured, inspected, sampled,and tested in accordance with this specification and have beenfound to meet the requirements of this specification. However,the designation marking, D2672, is not required.APPENDIX(Nonmandatory Information)X1. SOLVENT CEMENTING

40、JOINTS 10 IN. AND LARGERX1.1 If it is necessary, cut the pipe to length, making surethe cut is square. Chamfer cut ends and remove all burrs.X1.2 Examine bell and pipe end for damage before cement-ing joint.X1.3 Clean the matting surfaces of the pipe and fitting toremove dirt and foreign matter imme

41、diately before proceedingto the next step. Mark the pipe end with a bell depth line whichwill show when full penetration has been achieved.X1.4 Check the dry fit of pipe in bell. This is critical onlarger sizes because tolerances increase as the diametersincrease. If a slightly loose fit occurs, app

42、ly a second coat ofcement to the pipe end before assembly.X1.5 Prepare the joining surfaces by applying an approvedprimer. The surfaces are softened by this process. The primertakes longer to penetrate the surfaces at lower temperatures.Below 40F, it may take three to four times as long to get goods

43、urface penetration. Penetration is satisfactory when 2 to 5 milscan be scraped from the surface. The interior surface of the bellshould be given special attention because some silicone releaseagent residue may be present.X1.6 Immediately after priming, apply the solvent cementusing a wide bristle pa

44、int brush or a roller. Apply a heavy coatof solvent cement to the pipe end, and a light coat to the insideof the bell. Both mating surfaces should be completely covered.Apply sufficient cement to the mating surfaces to fill the gapbetween the pipe and the bell. If there are no finished surfacesbelow

45、 the joint, the cement may be poured on the pipe surfaceand inside the bell and spread with a brush. Use an extra-heavy-bodied cement to extend the working time when el-evated temperature and low humidity conditions exist.X1.7 The pipe must immediately be pushed into the bellwhile the (cement) surfa

46、ces are still wet. Two operators areneeded to simultaneously apply primer and cement, andsubsequently push the pipe into the bell. The force is providedby using a bar and wood plank. Alternatively, one or two“come-alongs” or lever pullers may be used, but sufficientchain with a choker strap must be

47、laid out on either side of thejoint before the cement is applied. Immediately after the primerand cement are applied, the “come-alongs” must be hooked up,and the joint is pulled together.X1.8 The new assembly must be held in place with theassembly apparatus for 1 to 2 min (depending on size andD2672

48、 143degree of interference) to permit the handling set to occur. Thehandling set must be completed before starting on the nextjoint. Handling set has been attained when there is no evidenceof joint push out after the holding force is released.X1.9 Before subjecting the joint to installation stresses

49、 suchas realignment to adjust slope, or bending, allow for initial set.See initial set times recommended in Table X1.1.X1.10 Allow the joint to cure for the times recommended inTable X1.2 before filling the line for test, or placing it inservice.NOTE X1.1Other joint systems are available for use when weatherand installation conditions make the solvent cementing of larger size PVCpipe very difficult.NOTE X1.2Also refer to Practice D2855.SUMMARY OF CHANGESComm
