scope:

This International Standard specifies a method for preparing butt-fusion-jointed test piece assemblies between
polyethylene (PE) pipes and spigot-ended fittings.
It specifies the assembly parameters involved, such as the ambient temperature, joint geometry and
fusion parameters, taking into account the service condition limits specified in the relevant product standards, as
well as the type of pipe to be used.
This International Standard is intended to enable the effect of site assembly variables on joint performance to be
determined. The fusion-jointing procedures and parameters used in the field can differ from those in this document,
depending on the manufacturer's written procedures and/or local standards.
NOTE 1 The assembly and fusion-jointing technique described in this International Standard is applicable whatever the
polyethylene resin employed, provided it is used in accordance with ISO/TR 11647. Deviations from the fusion cycle specified,
in order to demonstrate joint performance, may be considered in accordance with the notes in Annex A and B.
