24、 givenin Table 3 through Table 11.NOTE 4Additional fittings in IPS dimensions are included in Speci-fication D 3311.6.3 Deflection Load and Crush Resistance:6.3.1 PipeThe pipe shall support a minimum load of 600lbf/linear ft (810 N/m) at 15 % deflection of the originaldiameter (deflection load), and

25、 shall deflect 60 % of theoriginal diameter (crush resistance) without cracking, rupture,or other visible evidence of failure when tested in accordancewith 7.4. The minimum pipe stiffness at 5 % deflection shall be115 lbf/in.in. (800 kPa).6.3.2 FittingsIndividual fittings unassembled shall with-stan

27、burstpressure of pipe shall be 500 psi (3.45 MPa) and the minimumburst pressure of fittings shall be 200 psi (1.38 MPa).NOTE 5The minimum burst pressure for fittings are lower than thatfor pipe because the geometry is such, particularly area and radii, that thestresses produced in the wall of the fi

28、tting are higher than those producedin pipe tested at the same internal pressures. This requirement is intendedonly for the purpose of quality control to ensure that the pipe and fittingshave no weak areas, particularly at flow and weld lines.6.5 Flattening ResistanceThe average decrease in insidedi
