标准摘要
[中文适用范围]： 本国际标准建立了系统内对象终端识别的一般原则，适用于所有技术领域（如机械工程、电气工程、建筑工程、过程工程）。它们可用于基于不同技术的系统或结合多种技术的系统。 产品上终端标识的标记要求不属于本出版物的范围。 注：本标准基于ISO/EC 81346系列国际标准中建立的系统结构化一般原则，包括系统信息结构化，由IEC和ISO联合发布。 [外文原描述]： IEC 61666:2010+A1:2021 establishes general principles for the identification of terminals of objects within a system, applicable to all technical areas (for example mechanical engineering, electrical engineering, construction engineering, process engineering). They can be used for systems based on different technologies or for systems combining several technologies. This second edition cancels and replaces the first edition of IEC 61666 published in 1997 and edition constitutes a technical revision. It includes the following substantial changes with respect to the previous edition: - the terminology used in the publication has been adapted to the one used in IEC 81346-1 Ed. 2; - a more comprehensive description of the designation principles is provided; - additional examples illustrating terminal designations related to the function aspect and location aspect are provided; - an additional example illustrating the use of terminal designation sets is provided; - the former informative Annex A has been turned into a clause in the standard. IEC 61666:2010 has the status of a horizontal standard in accordance with IEC Guide 108 .
