This Standard sets out a method for determining the pressure cycling resistance properties of pipes, joints, and fittings for pressure applications. The method assesses the ability of the pipe/fitting system to perform in an environment that involves cyclical loadings. This performance is based on a combination of the effects of material properties, manufacturing techniques, and pipe, fitting and joint design. The combination of these three properties determines the ability of pipes, joints, and fittings for pressure applications, to resist the propagation of cracks from stress concentrators and other flaws that may exist within the material.NOTES: 1 This Method is a standardized method for measuring performance, and should not be taken to represent a particular type of installation. It is an indicative test.2 Where pipe or fittings, tested according to this Standard, are installed in a situation where fluctuations exceed the parameters specified in this test, steps may be required to reduce these fluctuations, or the design engineer should consult the pipe or fitting manufacturer for advice.3 This Method may be unsuitable for pipe sizes above DN 100 due to equipment limitations.
