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.

as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.
ISO 11553-2 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee
SC 9, Electro-optical systems in collaboration with IEC/TC 76, Optical radiation safety and laser equipment.
This Draft International Standard 11553-2 is a revision of ISO 11553-2:2007 and includes the following
changes:
— The document has been technically revised.
— Annex C “Examples for the design of technical safety measures for hand-held laser processing
devices “ and Annex D “Recommendations for the selection of personal protective clothing for use
with HLD “ were added.
— An Annex ZA was added.
ISO 11553 consists of the following parts, under the general title Safety of machinery — Laser processing
machines:
— Part 1: General safety requirements
— Part 2: Safety requirements for hand-held laser processing devices
— Part 3: Noise reduction and noise measurement methods for laser processing machines and hand-held
processing devices and associated auxiliary equipment (accuracy grade 2)
