47、gth, for each size of pipingand each type of system being considered. Also select threesuitable couplings at random. Prepare three joined specimensby joining two pipe specimens with one coupling, using thefusion equipment and instructions supplied by the manufac-turer of the system. Fill each specim
48、en with water at 73.4 63.6F (236 2C) and cap, taking care to exclude all air fromthe system. Fix one end of the specimen to a pressurizingapparatus, and support the free end if necessary.

49、imens shall leak(laboratory performance test only, not for field use).8.5.2 Mechanical Joint Pressure Test Perform the pres-sure test on mechanical joints on test specimens prepared in amanner similar to that described in 8.5.1, except use appropri-ate pipe specimens where the joint is intended to join pipes ofTABLE 3 Average Waterway Diameter, in.
