Foreword
This document (EN ISO 11554:2006) has been prepared by Technical Committee ISO/TC 172
"Optics and optical instruments" in collaboration with Technical Committee CEN/TC 123 "Lasers
and photonics", the secretariat of which is held by DIN.

This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by November 2006, and conflicting national
standards shall be withdrawn at the latest by November 2006.

This document supersedes EN ISO 11554:2003.

This document has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Cyprus,
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

The text of ISO 11554:2006 has been approved by CEN as EN ISO 11554:2006 without any
modifications.
ANNEX ZA
(informative)
Relationship between this European Standard and the Essential
Requirements of EU Directive 98/37/EC

This European Standard has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association to provide one means of conforming to
Essential Requirements of the New Approach Directive for machinery 98/37/EC amended by
Directive 98/79/EC.
Once this standard is cited in the Official Journal of the European Communities under that Directive
and has been implemented as a national standard in at least one Member State, compliance with
the normative clauses of this standard confers, within the limits of the scope of this standard, a
presumption of conformity with the corresponding Essential Requirements 1.5.10 Radiation and
1.5.12 Laser equipment of that Directive and associated EFTA regulations.
WARNING: Other requirements and other EU Directives may be applicable to the products falling
within the scope of this International standard.

ISO 11554:2006(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 11554 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 9,
Electro-optical systems.
This third edition cancels and replaces the second edition (ISO 11554:2003), which has been technically
revised.
For the purposes of this International Standard, the CEN annex regarding fulfilment of European Council
Directives has been removed.
