scope:

This part 12 of IEC 60825 provides requirements and specific guidance for the manufacture and safe use of laser products and systems used for point-to-point or point-to-multipoint free space optical data transmission. This standard only addresses the open beam portion of the system. If portions of the equipment or system incorporate optical fibre that extends from the confinements of the enclosure(s), the manufacturing and safety requirements under IEC 60825 Part 2: Safety of optical fibre communication systems shall apply to those portions only. Sources for visible information transmission to the human eye are covered by IEC 60825-6. This standard does not apply to systems designed for purposes of transmitting optical power for applications such as material processing or medical treatment. This standard also does not apply to the use of systems in explosive atmospheres. Throughout this part of IEC 60825, light-emitting diodes (LEDs) are included whenever the word laser is used.
