Safety of laser products - Part 12: Safety of free space optical communication systems used for transmission of information
This part of EN 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 EN 60825-1 apply to those portions only. 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. The objective of this part of EN 60825 is to: - provide information to protect people from potentially hazardous optical radiation produced by free space optical communication systems (FSOCS) by specifying engineering controls and requirements, administrative controls and work practices according to the degree of the hazard; - specify requirements for manufacturing, installation, service and operating organisations in order to establish procedures and provide written information so that proper precautions can be adopted.

Varnost laserskih izdelkov - 12. del: Varnost optičnih komunikacijskih sistemov v prostem prostoru, ki se uporabljajo za prenos informacij (IEC 60825-12:2019)
Ta del standarda EN 60825 podaja zahteve in posebne smernice za izdelavo in varno uporabo laserskih izdelkov in sistemov, ki se uporabljajo za optični prenos podatkov od točke do točke ali od točke do več točk v prostem prostoru. Ta standard obravnava samo del sistema, ki obsega odprti žarek. Če deli opreme ali sistema vsebujejo optična vlakna, ki segajo od meja zaprtih prostorov, se proizvodne in varnostne zahteve po EN 60825-1 uporabljajo samo za te dele. Ta standard se ne uporablja za sisteme, zasnovane za prenos optične moči pri uporabah, kot so obdelava materiala ali medicinsko zdravljenje. Ta standard se prav tako ne uporablja za uporabo sistemov v eksplozivnih atmosferah. Cilj tega dela standarda EN 60825 je: – zagotoviti informacije za zaščito ljudi pred potencialno nevarnim optičnim sevanjem, ki ga povzročajo optični komunikacijski sistemi v prostem prostoru (FSOCS), z določitvijo inženirskega nadzora in zahtev, upravnega nadzora ter delovnih praks glede na stopnjo nevarnosti; – določiti zahteve za organizacije za proizvodnjo, vgradnjo, servis in obratovanje, da se vzpostavijo postopki ter zagotovijo pisne informacije za namen sprejetja ustreznih previdnostnih ukrepov.

SAFETY OF LASER PRODUCTS –
Part 12: Safety of free space optical communication
systems used for transmission of information
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment
