13.3.2 For NP3 pipes The longitudinal reinforcement given in this table is valid forpipes up to 2.5 m effective length for internal diameter of pipe up to 250 mmand up to 3 m effective length for higher diameter pipes.13.3.3 For NP4 Pipe The longitudinal reinforcement given in this table is valid forpipes up to 2.5 m effective length for internal diameter of pipe up to 250 mmand up to 3 m effective length for higher diameter pipes.13.3.4 Class NP3 and NP4 pipes of nominal internal diameter 900 mm and above, theeffective length may also be 1.25m.13.4 Workman ship and Finish13.4.1 Finish- Pipes shall be straight and free from cracks except that craze cracksmay be permitted.13.4.2 The ends of the pipes shall be square with their longitudinal axis so that whenplaced in a straight line in the trench, no opening between ends in contact shallexceed 3 mm in pipes up to 600 mm diameter (inclusive), and 6 mm in pipeslarger than 600 mm diameter.13.4.3 The outside and inside surfaces of the pipes shall be dense and hard and shallnot be coated with cement wash or other preparation unless otherwise agreedto between the purchaser and the manufacturer or the supplier.13.4.4 The inside surface of the pipe shall be smooth. For better bond, inner surfaceof the collar may be finished rough.13.4.5 The pipes shall be free from defects resulting from imperfect grading of theaggregate, mixing or moulding.13.4.6 Pipes shall be free from local dents or bulges greater than 3.0mm in depth andextending over a length in any direction greater than twice the barrel wallthickness.13.4.7 Pipes may be repaired, if necessary, because of accidental injury duringmanufacture or handling and shall be accepted if in the opinion of thepurchaser, the repairs are sound and appropriately finished and cured, and therepaired pipe conforms to the requirements of this specification.13.4.8 The deviation from straight in any pipe throughout its effective length, tested bymeans of a rigid straight edge as described in IS 3597 shall not exceed, for alldiameters, 3mm for every meter run.13.5 Tolerances :13.5.1 The following tolerances shall be permitted: Table No. 4.5Urban Administration & Development Department Page 151
