ISO 12176-3:2011描述了熔合操作员徽章的格式和内容，该徽章在聚乙烯（PE）管道系统施工期间用于供应气体燃料或水，以识别熔合操作员并激活或停用熔合连接设备。 ISO 12176-3:2011的目标是实现操作员徽章和符合ISO 12176-1或ISO 12176-2的熔接设备读卡设备之间的国际互操作性。熔接设备需要读取徽章的条形码或磁条代码，并以标准格式调用设备内的相应数据。

ISO 12176-3:2011 describes the format and the contents of a fusion operator's badge, which is used during the construction of polyethylene (PE) piping systems for the supply of gaseous fuels or water to identify the fusion operator and to activate or deactivate the fusion-jointing equipment. The objective of ISO 12176-3:2011 is to achieve international interoperability between the operator's badge and the card-reading equipment of fusion-jointing equipment conforming to ISO 12176？1 or ISO 12176？2. The fusion-jointing equipment is required to read either the bar code or the magnetic-stripe code of the badge and to call up the corresponding data within the equipment in a standard format.
