标准摘要
[中文适用范围]: IEC TS 60825-20:2025 提供了针对一级激光设备的辐射安全要求(规范性内容)和指南(信息性内容),适用于激光辐射朝向眼睛或面部时的故障考虑。本文件的范围不包括对额定发射安全性的要求。例如: − 带有激光光面部或眼部识别功能的设备; − 虚拟现实头戴设备或眼镜; − 通过眼部或面部动作进行手势追踪的设备; − 驾驶员监控摄像头; − 全身扫描仪(包括眼睛、面部和身体)。 本文件不适用的产品包括: − 医疗和眼科设备; − 汽车(激光雷达)、灯具; − 在专业(非消费者)环境下使用激光,且激光用于直接或长时间暴露于眼睛或面部的应用。 本文件为以下内容提供规范性要求和信息性指南: − 辐射安全分析; − 生产线测试; − 激光辐射发射的危险分析(采用改进后的以安全为重点的FMEA方法); − 典型故障模式及缓解技术的示例。 注:本文件后续所有关于FMEA的引用均指该以安全为重点的FMEA方法。 [外文原描述]: IEC TS 60825-20:2025 provides radiation safety requirements (normative) and guidelines (informative) for the consideration of faults for Class 1 laser devices with laser radiation directed towards the eyes or face. Requirements for the safety of the nominal emission are not in the scope of this document. Examples: − devices with laser light facial or ocular recognition; − virtual reality headsets or glasses; − devices with gesture tracking via eye or facial movements; − driver surveillance cameras; − full body scanners (including eyes, face, and body). Products exempted from this document include: − medical and ophthalmic devices; − automotive (lidars), lamps; − laser applications where the laser is used in a professional (non-consumer) setting and is intended for direct or long-time exposure of the eyes or face. This document provides normative requirements and informative guidelines for: − radiation safety analysis; − production-line testing; − hazard analysis for laser radiation emissions (using a modified safety-focused FMEA approach) NOTE all subsequent references to FMEA in this document refers to this safety-focused FMEA approach. − examples of typical failure modes and mitigation techniques
