The pipe walls shall be free of cracks, holes, blisters, voids, foreign
31、inclusions, or other defects that are visibleto the naked eye and that may affect the wall integrity. The ends shall be cut cleanly and squarely.

32、e are not permissible.6.2 Dimensions and Tolerance:6.2.1 Nominal SizeThe nominal size for the pipe and fittings shall be the inside diameter shown in Table 1.6.2.2 Inside DiameterThe average inside diameter for pipe and fittings shall not vary more than 6 1 % from the designdiameter when measured in
33、 accordance with 7.4.1.NOTE 2The outside diameters and the corrugation pitch of products manufactured to this specification are not specified; therefore, compatibilitybetween pipe and fittings from different manufacturers or the same manufacturer shall be verified.6.2.3 LengthThe pipe shall be suppl
34、ied in any length agreeable to both the owner and the manufacturer. Length shall not beless than 99 % of stated quantity when measured in accordance with 7.4.2.6.2.4 Minimum Inner-Liner ThicknessThe minimum inner-liner thickness of the pipe shall meet the requirements given inTable 1 when measured i

Pipe connected by bell and spigot joints shall not be perforated in thearea of the bells and spigots.NOTE 3For perforated pipe applicat
37、ions, the size of the embedment zone and permeability of the embedment material provide the desired level ofinfiltration or exfiltration. The pipe or embedment zone shall be wrapped with a geotextile designed to prevent migration of fine soils into the pipe orembedment zone. Where a geotextile is no
