IEC EN 60825-4 standard: safety of laser products: Laser guards. (cabins, enclosures, fairings,…)
IEC 60825-1 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.
IEC 60825-4 deals with protection against laser radiation only. Hazards from secondary radiation that may arise during material processing are not addressed.
This part of IEC 60825 standard 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 (cabin, enclosure, fairing,…) 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
If in doubt, consult the Laser Safety Officer (LSO) of your institution or workplace.
