15、ng materials shallbe commercial grade of E-type glass fibers in the form of mat,continuous roving, chopped roving, or roving fabric, having acoupling agent that will provide a suitable bond between theglass reinforcement and the resin.4.3 Surfacing MaterialIf reinforcing material is used onthe surfa
16、ce exposed to the contained substance, it shall be acommercial grade chemical-resistant glass or organic surfacingmat having a coupling agent that will provide a suitable bondwith the resin.4.4 Fillers and AdditivesFillers, when used, shall be inertto the environment and manhole construction. Additi
17、ves, suchas thixotropic agents, catalysts, promoters, pigments, etc., maybe added as required by the specific manufacturing process tobe used to meet the requirements of this standard. The resultingreinforced-plastic material shall meet the requirement of thisspecification.4.5 OtherPolyester continu
18、ous roving, polyester scrim,glass scrim, or other material, may be used. The resultingreinforced-plastic material shall meet the requirement of thisspecification.4.6 RibsWhen used, ribs may be manufactured as a solidconstruction or with materials applied over a structural ornon-structural form. The
19、resulting reinforced-plastic materialshall meet the requirement of this specification.5. Manufacture5.1 Manhole and wetwell cylinders, manway reducers, andconnectors shall be produced from glass fiber-reinforced poly-ester resin with construction determined by the particularprocess of manufacture an
20、d configuration. The process mayinclude contact molding, compression molding, pultrusion,filament winding, resin transfer molding, spray up, handlay-up, centrifugal casting, or other methods. Ribs may beattached to the interior or the exterior surface.5.2 Interior AccessAll manholes or wetwells shal
21、l bedesigned so that a ladder or step system can be supported bythe installed manhole or wetwell.5.3 Manway ReducerManway reducers may be eccentricor concentric with respect to the larger portion of the manhole.5.4 Cover and Ring SupportThe manhole shall provide anarea from which a typical ring and
22、cover plate can be supportedwithout damage to the manhole.5.5 Assembly JointsProduct segments may be joined to-gether to form a complete manhole or wetwell.6. Requirements Requirements6.1 Workmanship:6.1.1 Exterior SurfaceThe exterior surface shall be rela-tively smooth with no sharp projections. Ha
23、nd-work finish isacceptable if enough resin is present to saturate all fibers. Theexterior surface shall be free of blisters larger than 0.5 in. (12.7mm) in diameter and delamination. Fibers loosely attached(can be removed with wire brush) are allowed if not excessive.Paint or other coatings that im
24、pair the visual inspection of thelaminate are not allowed. Indentations or other shape imper-fections that will not affect performance are allowed.6.1.2 Interior SurfaceThe interior surface shall be resinrich with no exposed fibers. The surface shall be free ofcrazing, delamination, blisters larger
