Joint materials by butt fusion processes on water networks LEGACY

This Standard is about jointing materials by butt fusion processes.  Butt fusion processes may be carried out in all weather conditions using non-automatic and automatic machines and on parent materials with the same SDR rating, and polymer type.
Jointing materials by butt fusion includes providing weather protection, checking joint preparation, equipment and consumables, monitoring machinery, making butt joints to specification, de-beading, shutting down equipment and dealing with waste.
This Standard is for anyone in water network construction who carries out butt fusion jointing.
