ALSO NUMBERED AS BS 2782 PT11 MTD 1111A 1996 Gives a test method for 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. Also assesses leaktightness and resistance to sagging
