2、case of revision, the year of last revision. A number 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 Department of Defense.1. Scope1.1 This sp

3、ecification covers the socket produced for sol-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 socket di-mensions, burst pressure, and joint tightness tests of the solventcemen

31、.6. Workmanship6.1 Each socket (bell) is required to be uniform in depth,circular in cross section concentric with the pipe, and to havean end as square as commercially practicable.7. Retest and Rejection7.1 If the results of any test(s) do not meet the requirementsof this specification, the test(s)

32、 shall be conducted again onlyby agreement between the purchaser and the seller. Under suchagreement, minimum requirements shall not be lowered, nortests omitted, substituted, changed, or modified, nor shallspecification limits be changed. If upon retest, failure occurs,the quantity of product repre

33、sented by the test(s) does not meetthe requirements of this specification.8. Sampling and Test Specimens8.1 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 th

34、e marking in their central sections. The centralsection is that portion of pipe which is at least 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

35、inserting thespigot one third to two thirds of socket (bell) depth.9. Conditioning9.1 Condition the test specimens at 73.4 6 3.6F (23 62C) and 50 6 5 % relative humidity for not less than 40 hprior to test in accordance with Procedure A of Practice D 618,for those tests requiring conditioning.10.

36、st Methods10.1 Test ConditionsConduct the tests in the StandardLaboratory Atmosphere of 73.4 6 3.6F (23 6 2C) and 50 65 % relative humidity, unless otherwise specified in PracticeD 618 or in this specification.10.2 Socket Joint AssemblyAssemble the socket joint perPractice D 2855, and condition at 7

37、3.4F (23C) for a mini-mum of 48 h.10.3 Burst Pressure Test of Joint AssemblyDetermine theburst pressure of one specimen in accordance with Test MethodD 1599. The assembled socket (bell) joint shall be within themiddle 30 % of the overall specimen length. The time to failureof the specimen shall be b

38、etween 60 and 70 s.10.4 Socket Joint Tightness TestSubject the assembly toan internal pressure of 25 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 SpecificationsD

39、 1785, D 2241, D 2665 and F 512, is marked with ASTMdesignation D 2672, in addition to the pipe standard, 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. Howeve

40、r,the designation marking, D 2672, is not required.APPENDIX(Nonmandatory Information)X1. SOLVENT CEMENTING 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 beforeceme

41、nting joint.X1.3 Clean the matting surfaces of the pipe and fitting toremove dirt and foreign matter immediately 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

42、 onlarger sizes because tolerances increase as the diametersincrease. If a slightly loose fit occurs, apply 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 pen

43、etrate the surfaces at lower temperatures.Below 40F, it may take three to four times as long to get goodsurface 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 releaseage

44、nt residue may be present.X1.6 Immediately after priming, apply the solvent cementusing a wide bristle paint 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

45、 the mating surfaces to fill the gapbetween the pipe and the bell. If there are no finished surfacesbelow the joint, the cement may be poured on the pipe surfaceD 2672 96a (2009)3and inside the bell and spread with a brush. Use an extra-heavy-bodied cement to extend the working time when el-evated t

46、emperature and low humidity conditions exist.X1.7 The pipe must immediately be pushed into the bellwhile the (cement) surfaces 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 p

47、lank. Alternatively, one or two“come-alongs” or lever pullers may be used, but sufficientchain with a choker strap must be 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

48、 together.X1.8 The new assembly must be held in place with theassembly apparatus for 1 to 2 min (depending on size anddegree 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 evide

49、nceof joint push out after the holding force is released.X1.9 Before subjecting the joint to installation stresses 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 D 2855
