音频/视频、信息和通信技术设备 第2部分:与IEC 62368-1:20 23相关的解释性信息

[中文适用范围]： 目的：确定IEC 62368-1:2023的用途和适用范围以及范围的排除内容。理由：范围排除了功能安全的要求。功能安全在IEC 61508-1中处理。因为范围包括可以控制安全系统的计算机，功能安全要求必然包括计算机过程和软件的要求。IEC 60950-23中提供的需求可以被修改并作为另一个-X文件添加到IEC 62368中。然而，由于IEC 62368-1基于危险的性质，IEC 60950-23的需求已被纳入IEC 62368-1的主体并使其更通用。添加IEC 60950-23需求的意图是保持IEC 60950-23技术需求的整体意图，按照IEC 62368-1的整体格式将其纳入IEC 62368-1，并简化和促进这些需求的应用。传统上，机器人涵盖在ISO文件的范围内，通常由ISO TC 299维护。ISO TC 299有个人护理机器人和服务机器人的工作组，并产生例如ISO 13482，机器人和机器人设备 - 个人护理机器人的安全要求。 [外文原描述]： 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
