IEC 62705:2022作为IEC 62705:2022 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62705:2022给出了辐射监测生命周期管理的要求系统(RMS)并为涵盖系统和设备的设计和鉴定的现有IEC标准的应用提供指导。本文件的目的是为RMSs的生命周期管理制定要求，并给出应用指导。本文件旨在与涉及辐射监测器、放射性物质取样、仪器校准、硬件和软件设计、分类和鉴定的最新版本的国际标准保持一致。本文件适用于安装在核设施中用于正常运行、预期运行事件（AOO）、设计基准事故（DBA）和设计扩展条件（DEC），包括严重事故（SA）的RMSs。这第二版取消并取代了2014年出版的第一版。与上一版相比，此版本包括以下重大技术变更:-标题的修改。-与事故状况的分类一致。-更新自第一版以来发布的新标准的参考资料。-更新术语和定义。

IEC 62705:2022 is available as IEC 62705:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62705:2022 gives requirements for the lifecycle management of radiation monitoring systems (RMS) and gives guidance on the application of existing IEC standards covering the design and qualification of systems and equipment. The purpose of this document is to lay down requirements for the lifecycle management of RMSs and give application guidance. This document is intended to be consistent with the latest versions of International Standards dealing with radiation monitors, sampling of radioactive materials, instruments calibration, hardware and software design, classification, and qualification. This document is applicable to RMSs installed in nuclear facilities intended for use during normal operation, anticipated operational occurrences (AOO), design basis accidents (DBA) and design extension conditions (DEC), including severe accidents (SA). This second edition cancels and replaces the first edition published in 2014. This edition includes the following significant technical changes with respect to the previous edition:
- modification of the title.
- to be consistent with the categorization of the accident condition.
- to update the references to new standards published since the first edition.
- to update the terms and definitions.
