7.6 Testing of valves:-7.6.1 GeneralUnless otherwise specified, all tests, except material tests, shall be made at the7.6.2 Material TestsMaterial tests required shall be those given in the corresponding materialspecifications referred to in table 1. The material shall be certified by thesuppliers with regard to their compliance to specifications laid down for themlable.7.6.3 Body Test (Hydrostatic)-All valves when completely assembled shall be subject to a hydrostatic bodytable 7.5 and shall show no leakage when pressure is applied to the inlet end,outlet end is blanked and valve is fully open.7.6.4 Back Seat TestBack seat test pressure shall be same as for the body. There shall be noleakage through the stuffing box when valve is fully open and pressure appliedto the inlet end and outlet end blanked. The leakage in this test shall be seenwith gland packing removed or gland loosened Back seat test shall beapplicable for gate and globe valves only.7.6.5 Seat Test (Hydrostatic) After being subjected to the body test, seats of valvesshall be tested hydrostatically to the pressure for the period specified in table7.5. The pressure shall be applied to each side of the gate of gate valves inclosed position, underside of the globe valve and outlet side of the check valve.In each case the other end of the valve shall be open to atmosphere. Seats ofcheck valves shall also be tested to one-fourth of the maximum cold workingpressure. The valves under the eat test pressure shall not show any leakagemore than that specified in IS: 6157- 1971Table No. 7.5Test pressure and test duration of valvesClass of valve Test Test pressureMinTest durationMin(1) (2) (3) (4)MPaMinutesClass 1 Body test 1.5 2Seat Test 1.5 2Class 2 Body test 2.4 2Seat test 1.6 2Urban Administration & Development Department Page 78
7.7 Galvanized mild steel pipes7.7.1 The pipes (tubes) shall be galvanized mild steel hot finished seamless (HFS) orwelded (ERW) HRIW or HFW screwed and socketed conforming to therequirements of IS 1239 Part-1 for light, medium & heavy grade. They shall beof the diameter (nominal bore) specified in the description of the item, thesockets shall be designated by the respective nominal bores of the pipes forwhich they are intended.7.7.2 Galvanizing shall conform to IS 4736 : The zinc coating shall be uniformadherent, reasonably smooth and free from such imperfections as flux, ash anddross inclusions, bare batches, black spots, pimples, lumping runs, rust stainsbulky white deposits and blisters.
