ISO 12176-2:2008规定了与聚乙烯（PE）电熔配件一起使用的电熔控制装置的性能要求，用于供应气体燃料或输送人类用水，包括处理前的原水，以及输送通用水或其他流体。 控制单元分为三个输入电压等级:SVLV[安全，极低电压（高达50 V）]、LV[低电压（50 V至250 V）]和HV[高电压（250 V至400 V）]。 ISO 12176-2:2008适用于电熔控制装置，其设计用于PE管道和配件之间的接头施工，符合气体燃料供应或输水的国际标准，其中控制装置的正常工作温度在- 10°C至+40°C。如果预期温度超出该范围，则制造商和买方应就合适的操作极限达成一致。 ISO 12176-2:2008适用于基于标准电阻丝加热技术的配件系统的电流或电压控制控制单元。

ISO 12176-2:2008 specifies performance requirements for electrofusion control units for use with polyethylene (PE) electrofusion fittings for the supply of gaseous fuels or for the conveyance of water for human consumption, including raw water prior to treatment and for the conveyance of water for general purpose or other fluids. The control units are divided into three input voltage classes: SVLV [safety, very low voltage (up to 50 V)], LV [low voltage (50 V to 250 V)] and HV [higher voltage (250 V to 400 V)]. ISO 12176-2:2008 is applicable to electrofusion control units designed for use in the construction of joints between PE pipes and fittings conforming to International Standards for the supply of gaseous fuels or for the conveyance of water, where the normal operating temperature of the control unit is in the range -10 °C to + 40 °C. If temperatures outside this range are expected, suitable operating limits are subject to agreement between manufacturer and purchaser. ISO 12176-2:2008 is applicable to control units with current or voltage control for fitting systems based on standard resistance wire heating technology.
