标准摘要
[中文适用范围]： IEC 60825-4 规定了用于封闭激光加工机器工艺区的激光防护装置（包括永久性和临时性，例如用于服务）的要求，以及专有激光防护装置的规格。本文件适用于防护装置的所有部件，包括透明（可见透光）屏幕和观察窗、面板、激光帘和墙。此外，本文件还指出如何评估和指定激光防护装置的防护特性，以及如何选择合适的激光防护装置。 [外文原描述]： IEC 60825-4:2022 deals with basic issues concerning laser guards, including human access, interlocking and labelling, and gives general guidance on the design of protective housings and enclosures for high-power lasers. Laser guards may also comply with standards for laser protective eyewear, but such compliance is not necessarily sufficient to satisfy the requirements of this document. This part of IEC 60825 specifies the requirements for laser guards, permanent and temporary (for example for service), that enclose the process zone of a laser processing machine, and specifications for proprietary laser guards. This document applies to all component parts of a guard including clear (visibly transmitting) screens and viewing windows, panels, laser curtains and walls. In addition, this document indicates - how to assess and specify the protective properties of a laser guard, and - how to select a laser guard.
