Safety of laser products - Part 4: Laser guards
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: a) how to assess and specify the protective properties of a laser guard; and b) how to select a laser guard.
