IEC 60825-4:2006+A1:2008+A2:2011 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. The Amendment 1 adds an Annex G addressing the arrangement, installation and use of guided beam delivery systems. The Amendment 2 updates the Annex D, "Proprietary Laser Guard Testing". This consolidated version consists of the second edition (2006), its amendment 1 (2008) and its amendment 2 (2011). Therefore, no need to order amendments in addition to this publication.
