This practice describes criteria for the training, assessment and qualification of heat fusion equipment (HFE) operators in, but not limited to, a field environment in order to establish and maintain competency in the joining of Polyethylene (PE) and Polyamide (PA) piping systems. This HFE operator training and qualification is applicable to heat fusion joining of PE pipe and fittings to other PE pipe and fittings of related polymer chemistry specified in the heat fusion procedures or standards used. It is also applicable to heat fusion joining of PA pipe and fittings to other PA pipe and fittings of the same polymer chemistry specified in the heat fusion procedures or standards used. The heat fusion between PE pipe and fittings to PA pipe and fittings is NOT allowed. The HFE operator training and qualification shall be for butt fusion for either PE or PA piping products, using the specific brand and size range of fusion machine to be used by the HFE operator and the heat fusion procedures or standards specified. If the HFE operator trainee requests, the training shall also include saddle and/or socket fusion of PE pipe and fittings of related polymer chemistry specified in the heat fusion procedures or standards used. This standard does not include training on the electro-fusion of these piping products.
