Test Procedures <br /> Installed Smith Fibercast pipe systems should be tested <br /> prior to use to assure soundness of all joints and connections. <br /> In testing,sudden pressure surges or"water hammer"must <br /> be avoided,as in some instances surge or hammer can pro- <br /> duce pressures of several times the rating of the pipe and fit- <br /> tings. Locate pressure gauge in close proximity to the pres- <br /> surizing equipment—not directly on the piping system. <br /> Pressure gauge with the test pressure at midscale is recom- <br /> mended. <br /> The normal recommended procedure is to conduct a <br /> hydrostatic cyclic pressure test. The piping system is <br /> subjected to 10 pressurization cycles at 1'h times the antici- <br /> pated or design operating pressure. NOTE: For low pres- <br /> sure applications,it is best to use the pressure rating of the <br /> pipe as the design operating pressure,i.e.test at 1'h times <br /> 13 Installation Instructions <br />
