Safety of laser products. Laser guards | Status: Current, Superseded

1 Scope 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 standard applies to all component parts of a guard including clear (visibly transmitting) screens and viewing windows, panels, laser curtains and walls. Requirements for beam path components, beam stops and those other parts of a protective housing of a laser product which do not enclose the process zone are contained in IEC 60825‑1. In addition this part of IEC 60825 indicates:

1. a) how to assess and specify the protective properties of a laser guard; and
2. b) how to select a laser guard.
