BS EN 60445:2000 人机接口、标记与识别的基本原则与安全性原则.设备终端和用相应符号标志的终端的识别方法(包括字母数字标志识别系统通则)

This International Standard applies to the identification and marking of terminals of electrical equipment such as resistors, fuses, relays, conductors, transformers, rotating machines and, wherever applicable, to combinations of such equipment (e.g. assemblies). It also applies to the identification of terminations of certain designated conductors. This Basic Safety Publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It should be noted that one of the responsibilities of a technical committee is, wherever possible, to include or refer to requirements of Basic Safety Publications in standards for equipment within its scope. Consequently, the requirements of this Basic Safety Publication apply only if they are included, or are referred to in those standards.
