16、 West Conshohocken, PA 19428-2959. United States13.2 Definitions:3.2.1 PVCO pipeabbreviation for oriented poly(vinylchloride) plastics. PVCO pipe is PVC pressure pipe whichattains a relatively high strength by reorienting the molecules.Conventionally extruded PVC pipe is expanded circumferen-tially
17、(for example, 2-in. diameter is expanded to 4-in. diam-eter) through the application of pressure and temperature. Theexpansion reorients the PVC molecular structure in the hoopdirection, thereby increasing the material strength.3.3 Definitions of Terms Specific to This Standard:3.3.1 expansion ratio
18、 (ER)the ratio of the finished PVCOpipe outside diameter to the outside diameter of the originalstarting stock.3.3.2 standard thermoplastic pipe material designationcodethe molecularly oriented poly(vinyl chloride) materialsdesignation code shall consist of the abbreviation PVCO forthe type of plast
19、ics, followed by the ASTM type and grade inarabic numerals and the hydrostatic design stress in units of100 psi (0.69 MPa) with any decimal figures dropped. TheASTM type and grade shall be that of the starting stockmaterial. The hydrostatic design stress shall be that of thefinished PVCO pipe.3.3.2.
20、1 DiscussionA complete material designation codeshall consist of four letters and four figures (for example; aPVCO pipe manufactured from 12454 (Type 1, Grade 1)material starting stock and having an HDB of 7100 psi (48.92MPa) HDS of 3550 psi) (24.46 MPa) will have a materialdesignation code of PVCO
21、1135).3.3.3 starting stockthe conventionally extruded PVC pipeof uniform wall thickness which will be expanded to a largerdiameter, molecularly oriented pipe.3.3.4 wall-thickness-ratio (WTR)the ratio of the finishedproduct wall thickness to the wall thickness of the startingstock.4. Classification4.
22、1 GeneralThis specification covers PVCO made fromPVC plastic pipe, starting stock, having a hydrostatic designstress of 2000 psi (13.78 MPa) determined in accordance withTest Method D2837. Finished PVCO pipe shall have a hydro-static design stress of 3550 psi (24.46 MPa) determined bytesting in acco
23、rdance with Test Methods D1598, with dataevaluated in accordance with Test Methods D2837,asin6.3.2.5. Materials5.1 GeneralPoly(vinyl chloride) plastics used to makePVCO pipe meeting the requirements of this specification arecategorized by means of two criteria, namely (1) short-termstrength tests; a
24、nd (2) long-term strength tests.5.1.1 Supplementary RequirementThis applies whenevera regulatory authority or user calls for the product to be used toconvey or to be in contact with potable water. Potable waterapplications products intended for contact with potable watershall be evaluated, tested, a
25、nd certified for conformance withANSI/NSF Standard 61 or the health effects portion of NSFStandard No. 14 by an acceptable certifying organization whenrequired by the regulatory authority having jurisdiction.5.2 Basic MaterialsThis specification covers PVCO pipemade from PVC compounds having certain
26、 physical andchemical properties as described in Specification D1784.5.3 The PVC compound used for the starting stock of thispipe shall equal or exceed the following cell classificationdescribed in Specification D1784: PVC 12454 (Type 1, Grade1). Recycled materials shall not be used in the compound.
27、5.4 Rework MaterialsClean, rework material, generatedfrom the manufacturers own pipe production, shall be permit-ted to be used by the same manufacturer, as long as the pipeproduced meets all the requirements of this specification.6.

Thereafter, itshall be completed whenever there is a change in the ER(3.3.1), or the WTR (3.3.4), or whenever a change is made tothe compound which is outside the allowable limits of thePlastics Pipe Institute PVC compound range formula (
31、see PPITR-3). The pipe shall not fail, balloon, burst, or weep asdefined in Test Method D1598 at the test pressures given inTable 5 when tested in accordance with 7.4.6.3.2 Regression TestThis test shall be completed on arepresentative diameter at initial start-up. A representativediameter is one wh
32、ich has an ER, a WTR, and a compoundwhich is the same as the other diameters manufactured.Thereafter, it shall be completed on a representative diameterwhenever there is a change in the ER or the WTR, or whenevera change is made to the compound which is outside theallowable limits of the Plastics Pi

38、p, Finish, and AppearanceThe pipeshall be homogeneous throughout and free from visible cracks,holes, foreign inclusions, or other defects. The pipe shall be asuniform as commercially practicable in color, opacity, density,and other physical properties.NOTE 2Color and transparency or opacity should b
39、e specified in thecontract or purchase order.7. Test Methods7.1 ConditioningCondition the test specimen at 73.4 63.6F (23 6 2C) and 50 6 5 % relative humidity for not lessthan 40 h prior to test in accordance with Procedure A ofPractice D618 for those tests where conditioning is required.7.2 Test Co
40、nditionsConduct the tests in the standardlaboratory atmosphere of 73.4 6 3.6F (23 6 2C) and 50 65 % relative humidity, unless otherwise specified in the testmethods or in this specification.7.3 SamplingThe selection of the sample or samples ofpipe shall be as agreed upon between the purchaser and th
41、eseller. In case of no prior agreement, the sample selection of themanufacturer shall be deemed adequate.7.3.1 Test SpecimensNot less than 50 % of the test speci-mens required for any pressure test shall have at least a part ofthe marking in their central sections. The central section is thatportion
42、 of pipe which is at least one pipe diameter away froman end closure.7.4 Sustained Pressure TestSelect the test specimens atrandom. Test individually with water at the internal pressuregiven in Table 5, six specimens of pipe, each specimen shall be3 ft long (1000 mm) between end closures and bearing
43、 thepermanent marking on the pipe. Maintain the specimens at thepressure indicated for a period of 1000 h. Hold the pressure asclosely as possible, but within 610 psi (670 kPa). Conditionthe specimens at the test temperature of 73.4 6 3.6F (23 62C).7.4.1 Maintain the test temperature at 73.4 6 3.6F
44、(23 62C). Test in accordance with Test Methods D2837, exceptmaintain the pressure at the values given in Table 5 for 1000 h.Failure of two of six specimens tested shall constitute failure inthe test. Failure of one of the six specimens tested is cause forretest of six additional specimens. Failure o
45、f one of the sixspecimens tested in retest shall constitute failure in the test.Evidence of failure of the pipe shall be as defined in TestMethods D1598.7.5 Regression TestTest in accordance with procedures inTest Methods D1598, except that restrained end fittings shallbe permitted to be employed. W
46、arningSince rupture of thetest specimen is expected in quick-burst and high-strengthregression testing, well-shielded test equipment and protectivepersonal equipment should be used when conducting the tests.NOTE 3Since the test time is changing for a 100 h to 10 000 h, animplementation period to mee
47、t the new requirement is needed.7.6 Burst PressureDetermine the minimum burst pressurewith at least five specimens in accordance with Test MethodD1599, having the lengths specified in 7.4. The time of testingof each specimen shall be not less than 60 s.NOTE 4Times greater than 60 s may be needed to
48、bring thelarger-sized specimens to the burst pressure. The test is more difficult topass using greater pressuring times.7.7 FlatteningFlatten three specimens of the pipe, 2 in.(50 mm) long, between parallel plates in a suitable press untilthe distance between the plates is 40 % of the outside diamet
49、erof the pipe. The rate of loading shall be uniform and such thatthe compression is completed within 2 to 5 min. Upon removalof the load, examine the specimens for evidence of splitting,cracking, or breaking.7.8 Impact ResistanceDetermine the impact resistance inaccordance with the specification requirement section of TestMethod D2444. Test at 73.4 6 3.6F (236 2C) using a Tup Band flat plate support. Use a 20-lb (9-kg) tup.7.8.1 Test SpecimensSpecimens of pipe for impact testingshall be cut to lengths required in Test Method D
