Part 5: Manufacturer’s checklist for IEC 60825-1
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 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. 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".
IEC 60825-5, which is a Technical Report, has been prepared by IEC Technical Committee 76:
Optical radiation safety and laser equipment.
This third edition cancels and replaces the second edition of IEC TR 60825-5 published in 2003.
This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) a new class, Class 1C, was introduced;
b) the measurement condition 2 ("eye loupe" condition) was removed;
c) for compliance with non-beam hazards (8.14.1) according to relevant product safety
standards, a reference was made to corresponding product reports.
The text of this International Standard is based on the following documents:
Draft TR Report on voting
76/585/DTR 76/608/RVDTR
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 is to be used in conjunction with IEC 60825-1:2014.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60825 series, published under the general title Safety of laser
products, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this document using a colour printer.

5 Test (5) – Measurements for determining classification
5.1. Have measurements of laser radiation been carried out in accordance with the YES/NO/N.A.
requirements of Clause 5 of IEC 60825-1:2014?
________________________________________________________________________
________________________________________________________________________
5.1.1. If NO, have measurements been deemed unnecessary by virtue of the physical YES/NO/N.A.
characteristics and limitations of the laser source, so that the laser product is placed
clearly in a particular class according to IEC 60825-1:2014, Clause 5?
________________________________________________________________________
________________________________________________________________________
5.1.2 If NO, measurements for the determination of classification are required and shall be
carried out in accordance with the requirements of Clause 5 of IEC 60825-1:2014
before proceeding further.
________________________________________________________________________
________________________________________________________________________
5.1.3 If NO is applicable to a reasonably foreseeable single fault condition, is the emission YES/NO/N.A.
in that case reduced to a level below the AEL by automatic reduction in a duration
within which it is not reasonably foreseeable to have human access?
________________________________________________________________________
________________________________________________________________________
If YES, have measurements of laser radiation been carried out during operation of
5.1.4 YES/NO/N.A.
the laser product, and under each and every reasonably foreseeable single fault
condition except for the fault conditions evaluated under 5.1.3?
NOTE 1 Automatic reduction includes physical limitation of the emission such as
component or system failure to a safe condition. It does not include manual
reduction or termination of the emission.
For example, a scanning safeguard may not react fast enough to prevent emission
above the AEL during the fault condition; however, this might be acceptable for
products where exposure of people is unlikely.
Acceptable modes of analysis of the probability and risk regarding failures are FMEA
(failure mode and effect analysis), etc. (see for instance IEC 61508 (all parts)).
Probability analysis may be used to assist in determining "reasonably foreseeable
single fault conditions".
NOTE 2 Classification is determined during operation, and restrictions on
maintenance are then dependent upon the classification of the product.
NOTE 3 Single fault conditions can be assessed by methods other than physically
inducing the fault for the test.
________________________________________________________________________
________________________________________________________________________
5.1.5 If YES, state the following:
– classification (e.g. Class 1): YES/NO/N.A.
________________________________________________________________________
– wavelength or wavelength range of accessible laser radiation: YES/NO/N.A.
________________________________________________________________________
– the appropriate time base for the product: YES/NO/N.A.
________________________________________________________________________
– the angular subtense of the source where applicable:
YES/NO/N.A.
________________________________________________________________________
A statement of the angle of subtense is not needed when a default measurement
method is applied (see 5.4.2); if C > 1, the measurement according to 5.4.3 shall be
performed.
– the emission time profile (CW, pulse repetition rate, pulse length, peak power, YES/NO/N.A.
etc.):
________________________________________________________________________
________________________________________________________________________
– the measurement aperture and measurement distance: YES/NO/N.A.
________________________________________________________________________
Has the position of the apparent source been determined? YES/NO/N.A.
________________________________________________________________________
NOTE 1 This might be in order to place the measurement aperture at the required
measurement distance. In case of a default (simplified) evaluation, the measurement
is taken from a reference point listed in Table 11 of IEC 60825-1:2014.
Maximum level of accessible laser radiation: YES/NO/N.A.
________________________________________________________________________
For Class 1, 1M, 2, 2M or Class 3R, does the accessible emission exceed the AEL YES/NO/N.A.
of Class 3B as determined with a 3,5 mm diameter aperture placed at the closest
point of human access?
________________________________________________________________________
If YES, additional warning for skin and/or cornea/iris hazard is required (7.13). YES/NO/N.A.
NOTE 2 The measurement for skin and/or cornea/iris hazard is intended to verify if
accessible emissions exceed the AEL of Class 3B as determined with a 3,5 mm
diameter aperture placed at the closest point of human access.
________________________________________________________________________
________________________________________________________________________
– 12 – IEC TR 60825-5:2019 © IEC 2019
6 Classification (4) – Classification procedure
6.1 For Class 1, Class 1M, Class 2, Class 2M and Class 3R, have additional YES/NO/N.A.
measurements (see informative Annex A) with a 3,5 mm diameter aperture placed at the
closest point of human access been considered to determine warnings for skin and/or
cornea/iris hazard according to Clause 7(7.13 and 8.1 k)? If NO, follow pertinent rules
above according to Clause 6(5.3).
________________________________________________________________________
________________________________________________________________________
6.2 Is the product a Class 1C laser product? YES/NO/N.A.
If YES, determine accessible emissions according to (5.3 b).
_______________________________________________________________________
_______________________________________________________________________
6.3 Is laser product emitting CW beams of a single wavelength, which are well collimated YES/NO/N.A.
or are assumed to be from a small source?
If YES, the following procedure can be simplified and the following items do not need
to be considered:
6.6(4.3 b), 6.7(4.3 c), 6.8(4.3 d) and 6.10(4.3 f)
_______________________________________________________________________
_______________________________________________________________________
6.4 For the purpose of classification, was the following ranking of classes (in increasing YES/NO/N.A.
order of ocular hazard) used: Class 1, Class 1C, Class 1M, Class 2, Class 2M, Class
3R, Class 3B, and Class 4?
Class 1C is considered not to be an ocular hazard (similar to Class 1) but may
represent a skin hazard if used inappropriately and, according to (5.3 b), shall meet
requirements of any applicable vertical standards.
For classification of a laser product as Class 1M or 2M, the use of an aperture
specified as Condition 3 limits the amount of radiation that is collected by the pupil
from large diameter beams. When measured under Condition 1, Class 1M and Class
2M products may have higher energy or power level than the AEL of Class 2 or Class
3R. For such laser products, a classification of 1M or 2M is appropriate.
_______________________________________________________________________
_______________________________________________________________________
6.5 For a single wavelength laser product, is the spectral range of the emission line YES/NO/N.A.
narrow enough so that the AELs do not change?
_______________________________________________________________________
_______________________________________________________________________
Please clarify how you determined the AELs in 6.5.1 and 6.5.2.
6.5.1 If YES, this laser product is assigned to a class when the accessible laser radiation,
measured under the conditions appropriate to that class, exceeds the AEL of all lower
classes but does not exceed that of the class assigned.
_______________________________________________________________________
_______________________________________________________________________
6.5.2 If NO, this laser product is assigned to a class when the accessible laser radiation,
measured under the conditions appropriate to that class, exceeds the AEL of all lower
classes but does not exceed that of the class assigned for all wavelength ranges used
to determine the applicable AEL.
_______________________________________________________________________
_______________________________________________________________________
6.6 For laser product emitting two or more wavelengths, are all wavelengths shown as YES/NO/N.A.
additive in Table 1 of IEC 60825-1:2014?
_______________________________________________________________________
_______________________________________________________________________
6.6.1 If YES, is the sum of the ratios of the accessible laser radiation (measured under the YES/NO/N.A.
conditions appropriate to that class) to the AELs of those wavelengths greater than
unity for all lower classes but does not exceed unity for the class assigned?
This rule applies also to non-laser radiation that is coincident on the retina for wave-
lengths between 400 nm and 1 400 nm or coincident on the aperture stop for other
wave-length ranges. Therefore, the non-laser radiation shall be included for
classification under IEC 60825-1:2014, 4.3 b) 1).
In case of NO to this question, assign a higher laser class and repeat the evaluation.
_______________________________________________________________________
_______________________________________________________________________
6.6.2 If NO to 6.6, does the accessible laser radiation (measured under the conditions YES/NO/N.A.
appropriate to that class) exceed the AELs for all lower classes but does not exceed
the AEL for the class assigned for any wavelength?
In NO in response to the question in 6.6.2, assign a higher laser class and repeat the
evaluation.
_______________________________________________________________________
_______________________________________________________________________
6.7 For laser sources in the wavelength range from 400 nm to 1 400 nm, is the source YES/NO/N.A.
subtending an angle of subtense greater than αmin and the simplified (default)
evaluation method (5.4.2) is not used?
If YES, complete the evaluation for extended sources according to (4.3 c).
NOTE For a default condition in (5.4.2), the factor C = 1 is assumed.
_______________________________________________________________________
_______________________________________________________________________
6.8 For non-uniform, non-circular or multiple apparent sources and for comparison with the YES/NO/N.A.
retinal thermal limits, is the simplified method not used for the wavelength range from
400 nm to 1 400 nm and α >α ?
min
If YES, complete the evaluation according to (4.3 d).
_______________________________________________________________________
_______________________________________________________________________
6.9 Is every possible emission duration considered within the time base YES/NO/N.A.
when determining the classification of a product?
IF NO, refer to (4.3 e)
For a multi wavelength emission laser product with simultaneous and spatially
overlapping emission in the visible and in the non-visible part of the spectrum, where
the emission is assessed as additive (see Table 1), and where the visible part on its
own would be classified as Class 2 or 2M or 3R and the non-visible part on its own
would be classified as Class 1 or Class 1M, the time base for the assessment of the
non-visible emission may be 0,25 s.

_______________________________________________________________________
_______________________________________________________________________
6.10.1 IF Yes, verify compliance with 6.10.2 to 6.10.4.
6.10.2 Does the accessible emission of any group of pulses (or sub-group of pulses in a train) YES/NO/N.A.
delivered in any given time exceed the AEL for that time?
NOTE See also 6.9 (4.3 e) for an applicable time base.

6.10.4 Does the average power for a pulse train of emission duration T exceed the power YES/NO/N.A.
corresponding to the AEL for a single pulse of duration T (AEL )?
T
_______________________________________________________________________
_______________________________________________________________________
6.10.5 For wavelength range from 400 nm to 1 400 nm, does the energy per pulse exceed the YES/NO/N.A.
AEL for a single pulse multiplied by the correction factor C ?
NOTE 1 This requirement does not need to be assessed for comparison with photochemical
limits nor for the determination of the AEL of Class 3B.
NOTE 2 For more information about the repetitive pulsed and modulated emission,
please refer to (4.3 f).
