piping systems in the field of soil and waste discharge (low and high temperature)
inside buildings (marked with “B”) and of soil and waste discharge systems for both
inside buildings and buried in ground within the building structure (marked with “BD”).
This Technical Report provides material dependent installation techniques but it is
