TOLERANCE ON LENGTH :
Socket and Spigot Pipes = ± 100 mm
Plain ended Pipes = ± 100 mm
Flanged Pipes = ± 10 mm

TOLERANCE ON MASS :
Socket and Spigot Pipes = ± 5 percent

C.I. Double Flanged Pipes as per IS-1537-1976
TOLERANCE :
Tolerance on length : ± 10 mm
Tolerance on mass : ± 5 percent

HYDROSTATIC TEST :
For Hydrostatic Test, the Pipes are kept under pressure for 15 seconds. They are struck moderately with a 700 gm hammer, withstanding the pressure test without showing leakage, sweating or other defect of any kind.

C.I. Double Flanged Pipes as per IS-7181-1986
TOLERANCE :
Tolerance on length : ± 10 mm
Tolerance on mass : ± 5 percent for DN 200 & above
    + 8 percent for DN upto 150
    5 percent for DN upto 150
The standard working length of Pipes is 2.75 mtr. long (9 feet approx.) uto 600 mm dia and 2 mtr. long above 600 mm dia.

HYDROSTATIC TEST :
Pipes are tested hydraulically to prevent leakage, sweating or other defects of any kind. The pressure is applied internally, and steadily maintained for a period of 15 seconds, when pipes are struck moderately with a 700 gm. hammer.
