ISO 12176-1:2017规定了使用电动加热板进行聚乙烯（PE）管道系统对接熔焊的设备的一般特性和性能要求。 ISO 12176-1:2017适用于用于PE管道和配件对接熔焊的机械和压力激活设备，这些设备或用于供应气体燃料，符合ISO 4437？2[1]和ISO 4437？3[2]，或用于输送人类饮用水（包括处理前的原水）和一般用途的水，符合ISO 4427？2[3]和ISO 4427？3[4]。 带有自动控制器的对接熔合机应符合附录A中给出的附加要求。 注:本文件也适用于标称管道直径和标称壁厚大于本文件规定的对接熔合机。

ISO 12176-1:2017 specifies the general characteristics of, and performance requirements for, equipment for butt fusion jointing of polyethylene (PE) piping systems using electrically powered heater plates. ISO 12176-1:2017 is applicable to mechanical and pressure-activated equipment for butt fusion jointing of PE pipes and fittings either intended to be used for the supply of gaseous fuels, conforming to ISO 4437？2[1] and ISO 4437？3[2], or intended for the conveyance of water for human consumption (including raw water prior to treatment) and for the conveyance of water for general purposes, conforming to ISO 4427？2[3] and ISO 4427？3[4]. Butt fusion machines with an automatic controller are subject to additional requirements as given in Annex A. NOTE This document is also applicable to butt fusion machines for larger nominal pipe diameters and nominal wall thicknesses than given in this document.
