Workmanship, Finish, and Appearance6.1 WorkmanshipThe pipe shall be homogeneousthroughout and essentially uniform in color, opacity, density,and other pr

19、operties. The inside and outside surfaces shall besemimatte or glossy in appearance and free of chalking, sticky,or tacky material. The pipe walls shall be free of cracks, holes,blisters, voids, foreign inclusion, or other defects that arevisible to the naked eye and that may affect the wall integri

20、ty.Holes deliberately placed in perforated pipe are acceptable.The surfaces shall be free of excessive bloom. Bloom orchalking may develop in pipe exposed to direct rays of the sun(ultraviolet radiant energy) for extended periods and conse-quently these requirements do not apply to pipe after extend

21、edexposure to direct rays of the sun.6.2 Pipe Dimensions:6.2.1 Pipe DiametersThe outside and inside diameters ofthe pipe shall be within the tolerances given in Table 1 whentested in accordance with 8.6.1.6.2.2 Wall ThicknessPipe wall thickness shall meet therequirements of Table 1 when measured in

The layinglength shall be determined in accordance with 8.6.3.6.3 Fitting and Bell-End Dimensions:6.3.1 Socket DiametersThe inside diameters of the sock-ets shall comply

23、 with the dimensions in Table 2 when deter-mined in accordance with 8.7.1.6.3.2 Wall Thickness:6.3.2.1 For belled pipe and fittings fabricated from pipesections, the thickness of the belled section shall be consideredsatisfactory if the bell was formed from pipe meeting therequirements of Table 1.6.

24、3.2.2 For molded fittings, the wall thickness of the water-way and socket or bell shall be no less than the respectiveminimum thickness listed for the equivalent pipe wall in Table2. For reducing fittings or those with smaller inlets, theminimum wall thickness of each inlet shall be no less than the

25、minimum wall thickness for that size pipe.6.3.3 Socket DepthThe socket depth shall be not less thanthat shown in Table 2 when measured in accordance with 8.7.3.6.3.4 Laying LengthThe laying length shall meet therequirements shown in Table 3.

27、lbe not less than the values given in Table 5 when tested inaccordance with 8.10. This requirement does not apply tofittings.NOTE 2The 5 % deflection criterion, which was arbitrarily selectedfor testing convenience, should not be considered as a limitation withrespect to in-use deflection. The engin

28、eer is responsible for establishingthe acceptable deflection limit.NOTE 3The strength and load-carrying capabilities of plastic drainand sewer pipe are measured and reported as Pipe Stiffness, which isdetermined in accordance with Test Method D 2412. The term “crushstrength” is not applicable to pla

29、stic piping because (a) the values obtainedcan be significantly different, depending on the bedding, loading, ortesting technique used; and (b) the term derives from rigid pipe and refersto its ultimate strength at rupture.6.6 FlatteningThe pipe shall show no evidence of split-ting, cracking, or bre
