ALSO NUMBERED AS BS 2782 PT12 MTDS 1209A+B(1996) Gives a method for determination of the chemical resistance properties of glass-reinforced thermosetting plastics (GRP) pipes and fittings in a deflected condition for nominal sizes DN 100 and larger. Together with EN 705 it provides a method for evaluation of the effect of a chemical environment on the interior of a pipe or fitting after a specified period of time.
