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 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.
