Classification4.1 GeneralThis specification covers fiberglass sewerpipe defined
19、by raw materials in the structural wall (type) andliner, surface layer material (grade), and pipe stiffness. Table 1lists the types, liners, grades, and stiffnesses covered.NOTE 3All possible combinations of types, liners, grades, and stiff-nesses may not be commercially available. Additional types,
20、 liners,grades, and stiffnesses may be added as they become commerciallyavailable. The purchaser should determine for himself or consult with themanufacturer for the proper type, liner, grade, and stiffness of pipe to beused under the installation and operating conditions that will exist for theproj
21、ect in which pipe is to be used.4.2 Designation RequirementsThe pipe materials desig-nation code shall consist of the standard designation, ASTMD3262, followed by type, liner, and grade indicated in Arabicnumerals, and pipe stiffness by a capital letter. Table 1 presentsa summary of the designation
22、requirements. Thus a completematerial code shall consist of ASTM D3262, three numerals,and a capital letter.NOTE 4Examples of the designation codes are as follows: (1) ASTMD3262-1-1-3-A for glassfiberreinforced aggregate and polyester resinmortar pipe with a reinforced thermoset liner and an unreinf
23、orcedpolyester resin and sand surface layer having a minimum pipe stiffness of9 psi (62 kPa). (2) ASTM D3262-4-2-6-C for glassfiberreinforcedepoxy resin pipe with an unreinforced thermoset liner, no surface layer,having a minimum pipe stiffness of 36 psi (248 kPa).NOTE 5Although the Form and Style f
24、or ASTM Standards manualrequires that the type classification be roman numerals, it is recognizedthat few companies have stencil-cutting equipment for this style of type,and it is therefore acceptable to mark the product type in Arabic numbers.5. Materials and Manufacture5.1 GeneralThe thermosetting
25、 resins, glass fiber rein-forcements, fillers, and other materials, when combined as acomposite structure, shall produce piping products that meetthe performance requirements of this specification.5.2 Wall CompositionThe basic structural wall composi-tion shall consist of a thermosetting resin, glas
26、s-fiber reinforce-ment, and if used, an aggregate filler.5.2.1 ResinAthermosetting polyester or epoxy resin, withor without filler.5.2.2 ReinforcementA commercial grade of glass fiberscompatible with the resin used.5.2.3 AggregateA siliceous sand conforming to the re-quirements of Specification C33,
27、 except that the requirementsfor gradation shall not apply.5.3 Liner and Surface LayerA liner or surface layer, orboth, when incorporated into or onto the pipe, shall meet thestructural requirements of this specification.5.4 JointsThe pipe shall have a joining system that shallprovide for fluid tigh
28、tness for the intended service condition.Aparticular type of joint may be restrained or unrestrained andflexible or rigid depending on the specific configuration anddesign conditions.5.4.1 UnrestrainedPipe joints capable of withstandinginternal pressure but not longitudinal tensile loads.TABLE 1 Gen

38、cially available.NOTE 7Restrained joints typically increase service loads on the pipeto greater than those experienced with unrestrained joints. The purchaseris cautioned to take into consideration all conditions that may beencountered in the anticipated service and to consult the manufacturerregard
39、ing the suitability of a particular type and class of pipe for servicewith restrained joint systems.5.5 GasketsElastomeric gaskets used with this pipe shallconform to the requirements of Specification F477, except thatcomposition of the elastomer shall be as agreed upon betweenthe purchaser and the
40、supplier for the particular exposure tooily or aggressive chemical environments.6. Requirements Requirements6.1 WorkmanshipEach pipe shall be free from all defectsincluding indentations, delaminations, bubbles, pinholes,cracks, pits, blisters, foreign inclusions, and resin-starved areasthat, due to
41、their nature, degree, or extent, detrimentally affectthe strength and serviceability of the pipe. The pipe shall be asuniform as commercially practicable in color, opacity, density,and other physical properties.6.1.1 The inside surface of each pipe shall be free of bulges,dents, ridges, and other de
42、fects that result in a variation ofinside diameter of more than18 in. (3.2 mm) from that obtainedon adjacent unaffected portions of the surface. No glass fiberreinforcement shall penetrate the interior surface of the pipewall.6.1.2 Joint sealing surfaces shall be free of dents, gouges,and other surf

At least90 % of the total footage of any one size and stiffness,excluding special-order lengths, s
45、hall be furnished in thenominal lengths specified by the purchaser. Random lengths, iffurnished, shall not vary from the nominal lengths by morethan 5 ft (1.53 m), or 25 %, whichever is less.6.2.3 Wall ThicknessThe average wall thickness of thepipe shall not be less than the nominal wall thickness p

For pipe wall constructions thatproduce an altered neutral axis position, it is necessary to evaluate resultsand establish requirements substituting 2y for t.(y is the maximumdistance from the neutral axis to the pipe surface.)6.3.2 Control RequirementsTest pipe specimens periodi-cally in accordance with 8.2.2, following the procedure of8.2.2.1, or alternatively, the procedure of 8.2.2.2.6.3.2.1 When the procedure of 8.2.2.1 is used, the followingthree criteria must be met: (a) the average failure time at ea
