The failures such as leakage and burst are stemmed from the repetitive motions of bending and stretching of hydraulic hose assemblies in construction machines, agriculture machines, vehicles, and industrial heavy machines. These failures could induce big troubles. Therefore, the hydraulic hose itself eventually requires an estimation of life to operate the hydraulic system safely. In this research, we have qualitatively selected the efficient test items by the analysis of the life and potential failures of hydraulic hose. We have used more than seven of hydraulic hoses simultaneously for the research. We have applied impulse pressure and half omega flexing motions to the accelerated life testing. Test results have been expressed by employing Weibull plot.
