FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports, technical specifications or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this technical report may be the subject of
patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
Technical reports do not necessarily have to be reviewed until the data they provide are
considered to be no longer valid or useful.

IEC 60825-5, which is a technical report, has been prepared by IEC technical committee 76:
Optical radiation safety and laser equipment.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
76/160/CDV 76/187/RVC
Full information on the voting for the approval of this technical report can be found in the report
on voting indicated in the above table.
This document, which is purely informative, is not to be regarded as an International Standard.

SECTION ONE – GENERAL
NOTE – Numbers shown in parenthesis refer to the relevant clause in IEC 60825-1

1 Scope (1.1)
This technical report is applicable to laser products as described in IEC 60825-1.
2 Object (1.2)
The checklist is intended for use by manufacturers of laser products and their agents to
establish that each new or modified design complies with the requirements of IEC 60825-1:
1993. The checklist is not a substitute for IEC 60825-1. It is necessary to use IEC 60825-1 in
conjunction with the checklist, as relevant clauses and subclauses are referred to in the text.
The layout of the checklist is intended only as a guide. Manufacturers and examiners are
encouraged to produce their own document, omitting questions and clauses that are not
relevant to the types of product under examination, but noting in the appropriate positions the
numbers of such clauses stating, for example: "subclause 4.3.2: Question omitted – not
applicable".
The manufacturer should ensure that the examiner is a person competent in the inspection and
classification of laser products.
3 Definitions
The definitions of IEC 60825-1 apply.
