电气和测量仪表回路检查

[中文适用范围]： 本国际标准描述了完成回路检查的建议步骤，包括回路施工完成（包括安装和点对点检查）和冷调试启动之间的活动。本标准适用于新工厂的建设以及现有工厂E&I装置（包括PLC、BAS、DCS、面板安装和现场仪表）的扩建/改造（即改造）。它不包括配电系统的详细检查，除非它们与正在检查的回路（即电机启动器或四线发射器的电源）相关。 [外文原描述]： describes the steps recommended to complete a loop check, which comprises the activities between the completion of the loop construction (including installation and point-to-point checks) and the start-up of cold commissioning. Is applicable for the construction of new plants and for expansion/retrofits (i.e. revamping) of E&I installations in existing plants (including PLC, BAS, DCS, panel-mounted and field instrumentation). It does not include a detailed checkout of power distribution systems, except as they relate to the loops being checked (i.e. a motor starter or a power supply to a four-wire transmitter).
