过程工业中的控制系统 电气和仪表回路检查

[中文适用范围]： 本标准适用于过程工业中的控制系统，特别是电气和仪表回路的检查。它涵盖了回路的检查计划、内容、程序、文档记录以及质量保证和安全方面。标准不适用于以下领域：前期和后期活动、受监管行业、安全仪表系统、制造执行系统、先进过程控制、工业自动化和控制系统的安全性，以及用户特定的程序和要求。 [外文原描述]： IEC 62382:2024 defines procedures and specifications for loop check, which comprises the activities between the completion of the loop construction (including installation and point-to-point checks) and the beginning of cold commissioning. This document is applicable for the construction of new plants and for expansion or retrofits (i.e. revamping) of electrical and instrument (E&I) installations in existing plants (including PLC, 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). Loop checks can be performed throughout the lifecycle of the plant. This document is also applicable when loop checks are performed after commissioning. This document describes what is intended to be tested but not how the test is performed, due to the wide range of technologies and equipment available. The intent of this document is to provide a means for all parties, including the owner, the installer and the vendor, to clearly establish and agree on the scope of activities and responsibilities involved in performing these tests in order to achieve a timely delivery and acceptance of the automation system. The activities described in this document can be taken as a guideline and adapted to the specific requirements of the process, plant or equipment. This edition includes the following significant technical changes with respect to the previous edition: a) general re-organization of the content of the previous edition, moving informative content to the annexes; b) replacing the forms based on I/O type in IEC 62382:2012, Annex A to Annex E with an example of a generic loop check form; c) providing additional references to other applicable standards.
