This International Standard specifies the characteristics of automatic recognition systems (numerical
recognition by means of bar codes or magnetic cards, electromechanical recognition using implanted-resistor
connectors and self-regulation systems) that enable the energy supply to be delivered automatically to the
thermoplastic electrofusion fittings used in pipe jointing.
It is applicable to electrofusion fittings intended to be used for plastics piping systems for the conveyance of
gaseous fuels, water for human consumption (including raw water prior to treatment) and for general purposes,
or of other fluids.
