The pipe walls shall be free ofcracks, holes, blisters, voids, foreign inclusions, or otherdefects that are visible to the naked
40、 eye and that may affect thewall integrity. There shall be no delaminaiton or separation ofthe inner liner and the profile. The ends shall be cut squarelyand cleanly. Holes intentionally placed in perforated pipe shallbe permitted.6.1.1 Visible defects, cracks, creases, splits, obstruction toflow in
41、 perforations, or in pipe are not permissible.6.2 Dimensions and Tolerance:6.2.1 Inside DiameterThe average measured inside diam-eter for pipe and fittings shall not vary more than (+/) 1.0%from the inside diameter when measured in accordance with7.4.1.NOTE 3The outside diameters and the corrugation
42、 pitch of productsmanufactured to this specification are not specified; therefore, compatibil-ity between pipe and fittings from different manufacturers or the samemanufacturer shall be verified.6.2.2 LengthThe pipe shall be supplied in any lengthagreeable to both the owner and manufacturer. Length
43、shall notbe less than 99% of stated quantity when measured inaccordance with 7.4.2.6.2.3 Minimum Inner Liner ThicknessThe minimum innerliner thickness of the pipe shall meet the requirements given inTable 1 when measured in accordance with 7.4.3.6.2.4 PerforationsPerforations shall be cleanly cut,pl
44、aced in the valley of the corrugation rib, and uniformlyspaced along the length and circumference of the pipe. Dimen-sions of the perforations and the minimum perforation inletarea shall be as listed in Table 2. Other perforation dimensionsand configurations shall be permitted where required to meet
45、the needs of the specifier. All measurements shall be made inF2648/F2648M 113accordance with 7.4.4. Pipe connected by bell and spigot jointsshall not be perforated in the area of the bells and spigots.6.3 Pipe StiffnessMinimum pipe stiffness at 5% deflectionshall meet the requirements given in Table
46、 2 when tested inaccordance with 7.5.NOTE 4The 5 % deflection criterion, which was selected for testingconvenience, is not a limitation with respect to in-use deflection. Theengineer is responsible for establishing the acceptable deflection limit.6.4 Pipe FlatteningThere shall be no evidence of spli
47、t-ting, cracking, breaking, separation of seams, separation be-tween the exterior corrugation and inner liner, or combinationsthereof, when tested in accordance with 7.6.6.5 Pipe Impact StrengthThere shall be no evidence ofsplitting, cracking, breaking, separation of seams, separation ofthe outer an
48、d inner wall, or combinations thereof, when testedin accordance with 7.7.6.6 Fittings and Joining Systems:6.6.1 Only fittings supplied or recommended by the pipemanufacturer shall be used. Fittings shall be installed inaccordance with the manufacturers recommendations.6.6.2 The joining system(s) sha
49、ll be of a design thatpreserves alignment during construction and prevents separa-tion at the joints. Bell and spigot, external snap or split couplersare examples of typical designs.NOTE 5The ability of a joint to resist soil infiltration (soil tightness)shall be considered. Soil tightness is a function of opening size, channellength, and backfill particle size. A backfill material containing a highpercentage of Class III and Class IV
