These industry guidelines set out the principal requirements for equipment, jointing procedures, maintenance, servicing and calibration of equipment, records and training for jointing by socket electrofusion, and saddle electrofusion.

We particularly recommend reading Page 11, which has extensive information on surface preparation. Cleaning is a critical step and one that has the potential to introduce contaminates (and lead to a poorly-welded joint) if not done correctly.
