Safety of laser products - Part 4: Laser guardsstandard by International Electrotechnical Commission, 07/01/2022
standard by International Electrotechnical Commission, 07/01/2022
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
a) how to assess and specify the protective properties of a laser guard, and
b) how to select a laser guard.
NOTE 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.
This document deals with protection against laser radiation only. Hazards from secondary radiation that may arise during material processing are not addressed.
