28、equirements and Test Methods7.1 Assemble each coupling to be tested according to themanufacturers instructions between two sections of randomlyselected hubless cast iron soil pipe meeting the requirements ofCISPI 301 or Specification A888 and conduct deflection andshear tests. In addition, unrestrai

29、ned hydrostatic tests shall beperformed as detailed in 7.2. The deflection and shear testsshall be performed on each size and type coupling utilizing firstarticle approval as required not to exceed 120 days. Theunrestrained hydrostatic test shall be performed on randomlyselected couplings of each si

30、ze during the course of productionusing first article selection not to exceed 30 days.7.1.1 Deflection Test:7.1.1.1 A test apparatus such as the one shown in Fig. 2 issuggested. Other testing apparatus that provide restraint to theassembly shall also be permitted. Close the outboard ends ofthe pipe

31、with test plugs.7.1.1.2 Fill the assembly with water, expel all air, andhydrostatically pressurize to 8.6 psi (59.3 kPa) for the durationof the test. One pipe shall be rigidly supported and while theassembly is under pressure, raise the opposite end of the otherpipe 1 in. (25 mm) per lineal foot of

32、pipe. Maintain the pressurefor 15 min. Any leakage shall mean failure.7.1.2 Shear Test:7.1.2.1 Support two joined lengths of randomly selectedhubless cast iron soil pipe on blocks, a minimum of 112 in.(38.1 mm) high, at three locations. One length shall be aminimum of 24 in. (609.6 mm) in length, su

33、pported on blocks,one near the uncoupled end, and the other immediatelyadjacent to the couplings. Firmly restrain this length in positionas shown in Fig. 3. The other coupled length shall be aminimum of 5 ft (1.52 m) in length and supported by a singleblock 6 in. (152.4 mm) from the end of the pipe.

34、7.1.2.2 Fill the assembly with water and expel all air. Applya load of 50 lb per in. (22.7 kg) of nominal diameter at a point6 in. (152.4 mm) from the edge of the coupling upon a 12 in.(304.8 mm) length of 3 by 3 in. (76.2 by 76.2 mm) angle ironor load distribution pad located on the top of the pipe

35、immediately adjacent to the coupling of the pipe having onesupport only. Under this loading there shall be no visibleleakage or displacement of more than38 in. (9.53 mm) fromtrue alignment adjacent to the coupling, when an internalpressure equivalent to a 20 ft (6.10 m) head of water 8.6 psi(59.3 kP

36、a) is applied. Maintain the load and internal pressurefor 15 min.7.2 Unrestrained Hydrostatic Joint Test:7.2.1 Assemble each coupling to be tested according to themanufacturers instruction between two sections of machinedsteel pipe and conduct the unrestrained hydrostatic joint test.7.2.2 The assemb

Machine the plain ends of the pipe to be used for thethrust test to the correct diameters. Plain ends shall have 0.015in. (0.38 mm) de

38、ep grooves machined circumferentially aroundthem at18 in. (3.18 mm) intervals down the pipe section for adistance equal to that covered by the elastomeric sleeve of thecoupling being tested. The tool used to machine the groovesshall have a 60 included angle and cut into the pipe from aperpendicular

39、position. The surface between the grooves shallbe a lathe turned surface of 125 RMS.7.2.3 The plain ends of the pipe for the thrust test shall beuncoated and cleaned with acetone and thoroughly dried beforeeach assembly.7.2.4 Test Method:7.2.4.1 Support the pipe assemblies in a manner that doesnot r

40、estrain joint movement as shown in Fig. 4.7.2.4.2 Fill the pipe assembly (as required in 7.2) withwater, expelling all air. Increase the hydrostatic pressure at arate of 1 psi (6.9 kPa) every 30 s until the specified testpressure is reached. The specified test pressure shall be 30 psi(206.8 kPa) for

41、 112 in. (38.1 mm) through 5 in. (127 mm), 27psi (186 kPa) for 6 in. (152.4 mm), 15 psi (103.4 kPa) for 8 in.(203.2 mm), 9 psi (62 kPa) for 10 in. (254 mm), and 6 psi (31.3kPa) for 12 and 15 in. pipe. When the specified test pressure isreached, hold it for 15 min. Any leakage or axial jointmovement

42、of more than 0.150 in. (3.81 mm) shall mean failure.8.
