SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
Part 2-010: Particular requirements for laboratory equipment
for the heating of materials
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 specifications, technical reports 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 International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61010-2-010, has been prepared by IEC technical committee 66:
Safety of measuring, control and laboratory equipment.
This second edition cancels and replaces the first edition published in 1992, of which it
constitutes a technical revision.
It has the status of a group safety publication in accordance with IEC Guide 104.
The text of this standard is based on the following documents:
FDIS Report on voting
66/324/FDIS 66/329/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 2-010 is intended to be used in conjunction with IEC 61010-1. It was established on
the basis of the second edition (2001). Consideration may be given to future editions of, or
amendments to, IEC 61010-1.
– 4 – 61010-2-010  IEC:2003(E)
This Part 2-010 supplements or modifies the corresponding clauses in IEC 61010-1 so as to
convert that publication into the IEC standard Safety requirements for laboratory equipment
for the heating of materials.
Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. Where this part states “addition”, “modification”, “replacement”, or
“deletion” the relevant requirement, test specification or note in Part 1 should be adapted
accordingly.
In this standard:
1) the following print types are used:
– requirements: in roman type;
– NOTES: in small roman type;
– conformity and test: in italic type;
– terms used throughout this standard which have been defined in clause 3: SMALL ROMAN
CAPITALS;
2) subclauses, figures, tables and notes which are additional to those in Part 1 are numbered
starting from 101.
The committee has decided that the contents of this publication will remain unchanged until 2007.
At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

NOTE If all or part of the equipment falls within the scope of one or more other part 2 standards of IEC 61010 as
well as within the scope of this standard, it will also need to meet the requirements of those other part 2 standards.
In particular, if equipment is intended to be used for IVD purposes, it will need to meet the requirements of
IEC 61010-2-101
1.1.2 Equipment excluded from scope
Addition:
Add the following three new items after item i)
aa) equipment for the heating and ventilation of laboratories;
