34、indication of overstressed or failed pipe under installed conditions.NOTE 4Ultimate strength of concrete pipe in the buried condition isC655 142dependent on varying soil bedding factors and varying failure modes andshall not necessarily have a relationship to the ultimate strength as definedunder th

Dimensions and Permissible Variations8.1 Standard DiametersPipe shall be manufactured in thestandard inside diameters listed in Table 1.NOTE 5Diamet

37、ers other than those shown in Table 1 and diameterslarger than 144 in. are possibly available. When such sizes are required,the owner should contact the manufacturers in the area.8.2 Design TolerancesExcept as specified in this section,all permissible design tolerances shall be given in Section 5.8.

38、2.1 Internal DiameterThe internal diameter of 12through 24-in. pipe shall not vary more than 2 % of the designdiameter for 12-in. pipe and 112 % for 24-in. pipe withintermediate size variation being a linear scale between 2 and112 %.

39、more than 1 % of the design diameter or 638-in.,whichever is greater. These diameter requirements are based onthe average of four diameter measurements at a distance of12-in. from the end of the bell or spigot of the pipe. Diameterverification shall be made on the number of pipe selected fortest per

Compute the valuesin 9.1.1 and 9.1.2 for both the 0.01-in. crack and the ultimatestrength.9.1.1 Compute the

46、 estimated standard deviation, s,byEq 1or Eq 2, which equations yield identical values.s 5 =(Xi2 X!2#/n 2 1! (1)s 5 =(Xi22 (Xi!2/n#/n 2 1!
