This part of ISO 12176 specifies the performance requirements for equipment for butt fusion jointing of polyethylene (PE) piping systems, using electric heaters.
It is applicable to mechanical and pressure-activated equipment for butt fusion jointing PE pipes and fittings conforming to ISO 4437 and ISO 8085-2.
The normal ambient-temperature range in which the butt fusion machine is intended to operate is -10 ℃ to +40 ℃. Use outside this temperature range will need to be agreed between the user and the supplier of the machine.
Butt fusion machines with an automatic controller are subject to additional requirements as given in annex A.
