音视频、信息和通信技术设备 第2部分：IEC 62368-1:2023的解释性信息

[中文适用范围]： IEC TR 62368-2:2025 RLV包含官方的IEC国际标准及其红线版本。红线版本仅提供英文版，便于用户快速直观地比较官方IEC标准与其前一版之间的所有变更。IEC TR 62368-2:2025明确了IEC 62368-1:2023的目的和适用范围，并指出了适用范围中的排除项。适用范围排除了功能安全的要求，功能安全相关内容在IEC 61508-1中有所规定。由于适用范围包括可以控制安全系统的计算机，因此功能安全要求必然涵盖计算机流程和软件的要求。IEC 60950-23中提供的要求可以修改并作为另一份-X文档添加至IEC 62368标准中。然而，由于IEC 62368-1基于风险分析的性质，IEC 60950-23中的要求已整合到IEC 62368-1的正文中，并进行了通用化处理。增加IEC 60950-23要求的意图是保持IEC 60950-23技术要求的整体意图，按照IEC 62368-1的整体格式将其纳入IEC 62368-1，并简化和促进这些要求的应用。 传统上，机器人属于ISO文件的适用范围，通常由ISO TC 299负责维护。ISO TC 299设有个人护理机器人和服务机器人工作组，例如制定了ISO 13482《机器人和机器人设备——个人护理机器人安全要求》。在本文件中，仅包含那些被认为需要进一步背景参考信息或解释以帮助用户应用相关要求的IEC 62368-1的子条款。因此，并非所有编号的子条款都被引用。除非另有说明，所有引用均指向IEC 62368-1:2023中的条款、子条款、附录、图表或表格。 本第四版取代并废止了2018年发布的第三版，本版构成技术修订。与前一版相比，本版包含以下重大技术变更：a）考虑到IEC 62368-1第四版（IEC 62368-1:2023）中所作的变更，如IEC 62368-1:2023前言中所述。 [外文原描述]： IEC TR 62368-2:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TR 62368-2:2025 identifies the purpose and applicability of IEC 62368-1:2023 and the exclusions from the scope. The scope excludes requirements for functional safety. Functional safety is addressed in IEC 61508-1. Because the scope includes computers that can control safety systems, functional safety requirements would necessarily include requirements for computer processes and software. The requirements provided in IEC 60950-23 can be modified and added to IEC 62368 as another -X document. However, because of the hazard-based nature of IEC 62368-1, the requirements from IEC 60950-23 have been incorporated into the body of IEC 62368-1 and made more generic. The intent of the addition of the IEC 60950-23 requirements is to maintain the overall intent of the technical requirements from IEC 60950-23, incorporate them into IEC 62368-1 following the overall format of IEC 62368-1 and simplify and facilitate the application of these requirements. Robots traditionally are covered under the scopes of ISO documents, typically maintained by ISO TC 299. ISO TC 299 has working groups for personal care robots and service robots, and produces for example, ISO 13482, Robots and robotic devices - Safety requirements for personal care robots. In this document, only those subclauses from IEC 62368-1 considered to need further background reference information or explanation to benefit the user in applying the relevant requirements are included. Therefore, not all numbered subclauses are cited. Unless otherwise noted, all references are to clauses, subclauses, annexes, figures or tables located in IEC 62368‑1:2023. This fourth edition cancels and replaces the third edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) It takes into account changes made in the fourth edition of IEC 62368-1 (IEC 62368-1:2023) as identified in the Foreword of IEC 62368 1:2023
