prEN IEC 60825-12:2021

This document is applicable to products that emit laser radiation for the purpose of free space optical data transmission. This document does not apply to laser products designed for the purposes of transmitting optical power for applications such as material processing or medical treatment. This document also does not apply to the use of laser products in explosive atmospheres (see IEC 60079-0). Light-emitting diodes employed by free space optical communication systems, used for the purpose of free space optical data transmission, do not fall into the scope of this document. NOTE If the laser product incorporates an optical fibre that extends from the confinements of the enclosure, the requirements in IEC 60825-2 applies.
