标准摘要
[中文适用范围]： 本部分 IEC 60825 规定了激光防护罩的要求，包括永久性和临时性（例如用于维修）的防护罩，这些防护罩包围激光加工机的加工区域，以及专有激光防护罩的规范。 本文件适用于防护罩的所有组成部分，包括透明（可见光透射）屏幕和观察窗、面板、激光帘和墙壁。 此外，本文件还说明了： a) 如何评估和指定激光防护罩的保护性能； b) 如何选择激光防护罩。 注：光束路径组件、光束停止器和激光产品防护外壳中不包围加工区域的其他部分的要求包含在 IEC 60825-1 中。 本文件仅涉及对激光辐射的保护。材料加工过程中可能产生的二次辐射危害不在本文件范围内。 [外文原描述]： IEC 60825-4:2022 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 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.
