SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL, AND LABORATORY USE –

Part 2-130: Particular requirements for equipment intended
to be used in educational establishments by children

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.
International Standard IEC 61010-2-130 has been prepared by IEC Technical Committee 66:
Safety of measuring, control and laboratory equipment.
This first edition cancels and replaces IEC TS 62850, published in 2013.
This edition includes the following significant technical changes with respect to IEC TS 62850:
a) marking and documentation requirements;
b) stability and handling requirements.

– 4 – IEC 61010-2-130:2021 © IEC 2021
The text of this International Standard is based on the following documents:
FDIS Report on voting
66/724/FDIS 66/726/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2 and taking
into account ISO/IEC Guide 50:2014.
A list of all parts in the IEC 61010 series, published under the general title Safety
requirements for electrical equipment for measurement, control, and laboratory use, can be
found on the IEC website.
This document is to be used in conjunction with IEC 61010-1. It was established based on the
third edition (2010) of IEC 61010-1, including its Amendment 1 (2016) hereinafter referred to
as Part 1.
This document supplements or modifies the corresponding clauses in IEC 61010-1 to convert
that publication into the IEC standard: Particular requirements for equipment intended to be
used in educational establishments by children.
Where a particular subclause of Part 1 is not mentioned in this document, that subclause
applies as far as is reasonable. Where this document states "addition", "modification",
"replacement", or "deletion", the relevant requirement, test specification or note in Part 1
should be adapted accordingly.
In this standard, the following print types are used:
• requirements: in roman type;
• NOTES: in smaller roman type;
• conformity assessment and test: in italic type;
• terms defined used throughout this standard which have been defined in Clause 3: SMALL
ROMAN CAPITALS.
Subclauses, figures, tables and notes which are additional to those in Part 1 are numbered
starting from 101. Additional annexes are lettered starting from AA and additional list items
are lettered from aa).
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.
INTRODUCTION
This document specifies particular safety requirements for equipment and accessories
intended to be used in educational establishment by PUPIL OPERATORS. PUPIL OPERATORS are
for the sake of this document, children between the ages of 3 years and 16 years operating
electrical equipment under supervision of a RESPONSIBLE BODY.
Equipment and accessories are considered intended for use in educational establishments,
when it is either explicitly stated in accompanying documentation, or where sales and
marketing materials indicate such intended use. This does not limit the use of other
equipment for use in educational establishments, however equipment and accessories not
evaluated to the requirements of this document may need additional precautions and
attestation when used by PUPIL OPERATORS.
Readily predictable behaviour of PUPIL OPERATORS can include poking objects and materials
associated with equipment and accessories, which poses additional challenges for
determination of reasonably foreseeable misuse. Consequently, more stringent criteria for
access to potentially hazardous parts are required for educational establishment equipment
than for general laboratory use.
Moreover, the maximum temperatures of parts that may be touched by children should be
lower than for equipment handled only by adults. Ergonomic considerations and mechanical
risks need to be addressed with regard to the anthropomorphic dimensions of children instead
of adults.
This document includes the following significant changes with respect to Part 1, as well as
other changes:
a) a marking is added to indicate to the RESPONSIBLE BODY that the equipment is intended to
be used by PUPIL OPERATORS under supervision;
b) accessibility requirements are enhanced to take into account the propensity of children to
insert foreign objects wherever they can;
c) temperature limits have been decreased to take into account the greater sensitivity of a
child's skin;
d) mechanical access dimensions have been reduced to take into account the smaller
dimensions of a child's body;
e) limits for non-collimated optical radiation have been introduced;
f) limits for ionizing radiation have been reduced;
g) small detachable parts below certain dimensions have been prohibited;
h) manufacturers are required to consider the general unpredictability of the behaviour of
PUPIL OPERATORS.
