4.3.2.4 Where the coating material has a bitumen base, it shall be smooth andtenacious and hard enoughpenknife.4.3.2.5 When the pipes to be used for conveying potable water the inside coating shallnot contain any constituent soluble in such water or any ingredient which couldimpart any taste or whatsoever to the potable water after sterilization andsuitable washing of the mains.4.3.2.6 Pipes with or without sockets and flanges which are imperfectly coated orwhere the coating does not set or conform to the required quality, the coatingshall be removed and the pipes/flanges recoated.4.4 Hydrostatic site test pressures and hydraulic working pressure.4.4.1 Hydrostatic site test pressures and hydraulic working pressure of the newly laidpipe line is specified as under inTable No.4.6Refer Amendment No.1, (Annex E -Table 1) : IS 8329-2000DNAllowable operatingpressure(excludingsurge) AOPAllowable MaximumOperating pressure(Including surge) MOPAllowable site testPressure (STP)K7 K9 K7 K9 K7 K9MPa MPa MPa80 0.8 6.4 1.25 7.7 1.75 9.6100 0.8 6.4 1.25 7.7 1.75 9.6125 0.8 6.4 1.25 7.7 1.75 9.6150 0.8 6.4 1.25 7.7 1.75 9.6200 0.8 6.2 1.25 7.4 1.75 7.9250 0.8 5.4 1.25 6.5 1.75 7.0300 0.8 4.9 1.25 5.9 1.75 6.4350 0.8 4.5 1.25 5.4 1.75 5.9400 0.8 4.2 1.25 5.1 1.75 5.6450 0.8 4.0 1.25 4.8 1.75 5.3500 0.8 3.8 1.25 4.6 1.75 5.1600 0.8 3.6 1.25 4.3 1.75 4.8700 0.8 3.4 1.25 4.1 1.75 4.6750 0.8 3.3 1.25 3.9 1.75 4.4800 1.0 3.2 1.5 3.8 2.0 4.3900 1.0 3.1 1.5 3.7 2.0 4.21000 1.0 3.0 1.5 3.6 2.0 4.14.4.2 Other Test of Pipes :4.4.2.1 Mechanical test are carried out during the manufacture. One test shall beconducted for every batch of production.Urban Administration & Development Department Page 46
4.4.2.2 Tensile Test shall be conducted by cutting a sample from the spigot end of thepipe. This sample may be cut perpendicular to or parallel with the pipes axis,but in case of dispute the parallel to axis sample shall be used.4.4.2.3 Two methods of measuring the tensile strength may be used at themanufacturer's option.4.4.2.4 Method 1 - Machine the test bar to its nominal diameter + 10 percent, measurethe actual diameter before the test with an accuracy of 0.01 mm and use thismeasured diameter to calculate the cross-sectional area and the tensilestrength; or:4.4.2.5 Method 2 - Machine the test bar to its nominal area S 0 within a specifiedtolerance on diameter and use the nominal area to calculate the tensilestrength.4.4.3 Brinell Hardness Test :4.4.3.1 When tested in accordance with IS 1500, the Brinell hardness shall not exceed230 HB on the external un-machined surface.4.5 Marking4.5.1 Each pipe shall have as cast or stamped or legibly and indelibly painted on itwith the following appropriate marks:(a) Indication of the source of manufacture:(b) The nominal diameter:(c) Class reference;(d) The last two digits of the year of manufacturer:(e) The non-standard length of the pipe if specially ordered:(f) Where applicable, an indication of length over which the pipe is suitable forcutting on site: and(g) A short white line at the spigot end of each pipe with push-on joint in sizesDN 700 and above, to indicate the major axis of the spigot.4.6 Fittings4.6.1 Dimensional and other requirement for fittings for specified Diameter shallconform to the details given in tables 15 to 31 section 3 of the IS specificationcode IS: 9523: 2000.4.6.2 HYDROSTATIC TESTFor hydrostatic test, the fittings shall be kept under pressure for 10 seconds.They shall withstand the pressure test without showing any sign of leakage,sweating or other defect of any kind. The test shall be conducted before theapplication of surface coating.4.6.3 The fittings shall withstand the hydrostatic pressure given in table.4.7Hydrostatic test pressure for castingsUrban Administration & Development Department Page 47
