标准摘要
[中文适用范围]： IEC 60951的本部分提供了有关核电厂事故和事故后条件下工艺流中放射性连续在线或在线监测设备的设计原则和性能标准的一般指导。 IEC 60951-1 中给出了技术特性@测试程序@辐射特性@电气@机械@和环境特性的一般要求。除非另有说明，这些要求适用于本部分。 IEC 60951-4 仅适用于连续在线测量，即探测器通过放置在过程流中（即浸入）或邻近过程流（即直接通过管道或储罐）。它不适用于探测器在某些远程位置（采样组件）@测量流的代表性比例的监测器，这些监测器在 IEC 60951-2 的范围内。 IEC 60951-4 仅适用于事故和事故后状况的监测。正常和事故条件下的工艺流辐射监测设备属于 IEC 60768 的范围。 [外文原描述]： IEC 60951-4:2009 provides general guidance on the design principles and performance criteria for equipment for continuous in-line or on-line monitoring of radioactivity in process stream in nuclear power plants for accident and post-accident conditions. General requirements for technical characteristics, test procedures, radiation characteristics, electrical, mechanical, and environmental characteristics are given in IEC 60951-1. These requirements are applicable in this part unless otherwise stated. The main technical changes with regard to the previous edition are as follows: - clarify the definitions; - up-date the references to new standards published since the first edition; - update the units of radiation. This publication is to be read in conjunction with IEC 60951-1:2009 .
