It is a test in which the working life of polyethylene pipes and fittings is determined by aging in order to determine the resistance to a certain temperature and internal hydrostatic pressure related to the transport of liquids. In order for the material to work in the long term, it must be resistant to pressure and temperature. When polyethylene pipe fittings are subjected to internal hydrostatic pressure under the pressure, ambient stress, temperature and time specified in the standard, there should be no leakage and explosion during the test period.
