to seal the joint. The difference in circumferential measurement between the outside
circumference of the spigot and the inside circumference of the bell must not exceed
0.200 inch.

cement-mortar to level out to a uniform thickness throughout the cylinder. Continue
the spinning until the lining is thoroughly compacted and surplus water removed, and
the finished lining is smooth and uniform throughout.
C. Lining Thickness Tolerance: Not more than 1 percent less or 25 percent more than
the specified nominal thickness.
2.6 EXTERIOR COATING

accomplished by tightly sealing the ends of the cylinder with a waterproof membrane
to retain the moisture in the mortar. Steam curing may be used in lieu of or in
combination with moist curing on a time ratio basis of one (1) hour steam curing to
four (4) hours moist curing.
B. Moist cure the completed pipe for six (6) days minimum. Steam curing may be used
in lieu of moist curing.
