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

Attention IEC-CENELEC parallel voting
The attention of IEC National Committees, members of
CENELEC, is drawn to the fact that this Committee Draft for
Vote (CDV) is submitted for parallel voting.
The CENELEC members are invited to vote through the
CENELEC online voting system.

This document is still under study and subject to change. It should not be used for reference purposes.

Recipients of this document are invited to submit, with their comments, notification of any relevant patent rights of which they

are aware and to provide supporting documentation.
TITLE:

Safety requirements for electrical equipment for measurement, control and laboratory use - Part 2-051:

Particular requirements for laboratory equipment for mixing and stirring
NOTE FROM TC/SC OFFICERS:

This CDV is intended only to align IEC 61010-2-051:2015 with IEC 61010-1:2010 and its amendment 1:2016. A

revision this soon is justified by the large number of significant changes introduced by this amendment 1. With

this revision IEC 61010-2-051 will be in line with the latest requirements of IEC 61010-1 + A1.

This document contains no technical changes to already accepted base documents (IEC 61010-1:2010 and its

amendment 1:2016 and IEC 61010-2-051:2015) but one; Clause 6.8.3.1 is modified because otherwise it would

need a specific European deviation in order to be harmonised to the LVD 2014/35/EU (ref. NAC assessment of

IEC 61010-1/A1). Further technical development is reserved for a new amendment or edition to be initiated

separately as necessary.

This alignment is realised as a new 4th edition of IEC 61010-2-051 simply because of document control; the

previous edition 3.0 is based on the third edition of IEC 61010-1:2010 (without the Amendment 1:2016) and

amending it to incorporate the contents of IEC 61010-1 Amendment 1 would need an unnecessary repeating of

the requirements in that amendment 1 that are not particular for the equipment in the scope of IEC 61010-2-051.

Furthermore, technically, one would need to follow 4 documents in parallel to get the full text of this part 2

(61010-1:2010, 61010-1 A1:2016, 61010-2-051:2015, and 61010-2-051 A1).With this approach, and when the

consolidated version of IEC 61010-1:2010/A1:2016 conveniently is published, only two documents are needed.

41 in the subject dealt with may participate in this preparatory work. International, governmental and non-

42 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

43 with the International Organization for Standardization (ISO) in accordance with conditions determined by

44 agreement between the two organizations.

45 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

46 consensus of opinion on the relevant subjects since each technical committee has representation from all

47 interested IEC National Committees.

48 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

49 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

50 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

51 misinterpretation by any end user.

52 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

53 transparently to the maximum extent possible in their national and regional publications. Any divergence

54 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

55 the latter.

56 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

57 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

58 services carried out by independent certification bodies.

59 6) All users should ensure that they have the latest edition of this publication.

60 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

61 members of its technical committees and IEC National Committees for any personal injury, property damage or

62 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

63 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

64 Publications.

65 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

66 indispensable for the correct application of this publication.

67 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
