Essential Requirements Clause(s)/sub-clause(s) Remarks/Notes
of Directive 2006/42/EC of this EN
1.5.12 Clause 5, 6, 7 and 8.
1.7.4.2, m,  Related to the aspect of
radiation and emission.
WARNING 1 — Presumption of conformity stays valid only as long as a reference to this
European Standard is maintained in the list published in the Official Journal of the European
Union. Users of this standard should consult frequently the latest list published in the Official
Journal of the European Union.
WARNING 2 — Other Union legislation may be applicable to the product(s) falling within the
scope of this standard.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/

This document was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee
SC 9, Laser and electro-optical systems, in collaboration with IEC/TC 76, Optical radiation safety and laser
equipment.
This second edition cancels and replaces the first edition (ISO 11553-1:2005), which has been technically
revised with the following main changes:
— the terms "beam delivery systems", "beam path components", "beam shaping components", "beam
switching components" and "fibre optic cable" and "fibre connector" were added;
— the document was restructured;
