Plastics piping systems - Thermoplastics piping systems for soil and waste discharge inside buildings - Test method for resistance to elevated temperature cycling
This standard specifies a method for testing the resistance of thermoplastics piping systems for soil and waste discharge inside buildings, marked ""B"", or buried in the ground within the building structure, marked ""BD"" or ""UD"", to 1500 cycles of elevated temperature cycling. The method assesses leaktightness and resistance to sagging.
