More D It is suited primarily for pipes to be installed in buried applications, although it may be used to the extent applicable for other installations such as, but not limited to, jacking, tunnel lining, and slip lining rehabilitation of existing pipelines. The materials shall include the following: structural wall composition which shall consist of thermosetting resin, glass fiber reinforcement, and, if used, aggregate filler; a thermosetting polyester or epoxy resin with or without filler; E-type glass reinforcement; siliceous sand aggregates; liner and surface layers; unrestrained or restrained joints; and elastomeric gaskets. Pipe shall be supplied in the nominal diameters, lengths, wall thickness, squareness of pipe ends, and soundness.

Current edition approved June 10, Published August Originallypublished as D — Last previous edition D — Box , Ann Arbor,MI Thermoplastic or thermosetting liners orcoatings may be included. Not a routine quality control test. Table 1 lists the types, liners, grades, classes,and stiffnesses that are covered. N OTE 3—All possible combinations of types, liners, grades, classes,and stiffnesses may not be commercially available.
Additional types,liners, grades, and stiffnesses may be added as they become commerciallyavailable. The purchaser should determine for himself or consult with themanufacturer for the proper class, type, liner, grade and stiffness of pipeto be used under the installation and operating conditions that will exist forthe project in which the pipe is to be used. Table 1 presents a summary of thedesignation requirements. Materials and Manufacture 5. The evaluation should bein accordance with requirements for chemical extraction, taste, and odorthat are no less restrictive than those included in National SanitationFoundation NSF Standard This cell-type format, however, is subjectto misapplication since unobtainable property combinations can be selected if the user is not familiar with non-commercially available products.
Themanufacturer should be consulted. For typical joint detail see Fig. N OTE 7—Other types of joints may be added as they become commer-cially available. Requirements 6. The pipe shall be as uniform ascommercially practicable in color, opacity, density, and otherphysical properties. The pipe diametertolerances shall be as shown in Table 2 or Table 3, whenmeasured in accordance with 8. The actual laying length shall be the nominal length 6 2 in. Random lengths, if furnished, shallnot vary from the nominal lengths by more than 5 ft 1.
