8、ts,such aspush-on or other types of joints that prevent lateral displace-ment.Plain-end pipe for use with suitable couplings may befurnished.3.3 Unless otherwise specified,pipe shall have a nominallength of 18 or 20 ft(5.5 or 6.1 m).Amaximum of 20%of thetotal number of pipe of each size specified in
9、 an order may befurnished as much as 24 in.(610 mm)shorter than the nominallaying length,and an additional 10%may be furnished asmuch as in 6 in.(152 mm)shorter than the nominal layinglength.4.Tolerances or Permitted Variations4.1 DimensionsThe spigot end,bell,and socket of thepipe and the accessori
10、es shall be gaged with suitable gages atsufficiently frequent intervals to ensure that the dimensionscomply with the requirements of this specification.The small-est inside diameter(ID)of the sockets and the outside diameter(OD)of the spigot ends shall be tested with circular gages.Other socket dime
11、nsions shall be gauged as may be appropri-ate.4.2 ThicknessMinus thickness tolerances of pipe shall notexceed those shown below:Nominal Size,in.Minus Tolerance,in.(mm)14 to 420.07(1.8)480.08(2.0)54 to 640.09(2.3)NOTE1An additional minus tolerance of 0.02 in.(0.05 mm)shall bepermitted along the barre
