TITLE:
Safety requirements for electrical equipment for measurement, control, and laboratory use - Part
2-020: Particular requirements for laboratory centrifuges

PROPOSED STABILITY DATE: 2024
NOTE FROM TC/SC OFFICERS:
The revision is to align IEC 61010-2-020:2016 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 61010-2-020 will be in line with the latest requirements of IEC 61010-1 + A1.
Establishment of a new edition is for better readability instead of amending edition 3.

37 SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT FOR
38 MEASUREMENT, CONTROL, AND LABORATORY USE –
40 Part 2-020: Particular requirements for LABORATORY CENTRIFUGES
42 FOREWORD
43 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
44 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
45 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
46 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
47 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
48 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
49 in the subject dealt with may participate in this preparatory work. International, governmental and non-
50 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
51 with the International Organization for Standardization (ISO) in accordance with conditions determined by
52 agreement between the two organizations.
53 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
54 consensus of opinion on the relevant subjects since each technical committee has representation from all
55 interested IEC National Committees.
56 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
57 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
58 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
59 misinterpretation by any end user.
60 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
61 transparently to the maximum extent possible in their national and regional publications. Any divergence
62 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
63 the latter.
64 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
65 equipment declared to be in conformity with an IEC Publication.
66 6) All users should ensure that they have the latest edition of this publication.
67 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
68 members of its technical committees and IEC National Committees for any personal injury, property damage or
69 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
70 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
71 Publications.
72 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
73 indispensable for the correct application of this publication.
74 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
75 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
76 International Standard IEC 61010-2-020 has been prepared by IEC technical committee 66:
77 Safety of measuring, control and laboratory equipment.
78 This fourth edition cancels and replaces the third edition published in 2016. It constitutes a
79 technical revision and includes the following significant changes from the second edition:
80 a) alignment with changes introduced by Amendment 1 of 61010-1 third edition.
81 It has the status of a product safety publication in accordance with IEC Guide 104.
61010-2-020/Ed.4/CDV © IEC(E) 4 66/711/CDV

83 The text of this standard is based on the following documents:
CDV Report on voting
66/542/CDV 66/565A/RVC
85 Full information on the voting for the approval of this standard can be found in the report on
86 voting indicated in the above table.
87 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
88 This Part 2-020 is intended to be used in conjunction with IEC 61010-1. It was established on
89 the basis of the third edition (2010) and its Amendment 1 (2016).
90 This Part 2-020 supplements or modifies the corresponding clauses in IEC 61010-1 so as to
91 convert that publication into the IEC standard: Safety requirements for LABORATORY
92 CENTRIFUGES.
93 Where a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies
94 as far as is reasonable. Where this part states "addition", "modification" or "replacement", the
95 relevant requirement, test specification or note in Part 1 should be adapted accordingly.
96 In this standard:
97 1) the following print types are used:
98 – requirements: in roman type;
99 – NOTES: in small roman type;
100 – conformity and tests: in italic type;
101 – terms used throughout this standard which have been defined in Clause 3: SMALL
102 ROMAN CAPITALS.
103 2) subclauses, tables or figures which are additional to those in Part 1 are numbered starting
104 from 101; additional annexes are lettered AA, BB, etc.
105 A list of all parts of the IEC 61010 series, under the general title: Safety requirements for
106 electrical equipment for measurement, control, and laboratory use, may be found on the IEC
107 website.
108 The committee has decided that the contents of this publication will remain unchanged until
109 the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
110 related to the specific publication. At this date, the publication will be
111 • reconfirmed,
112 • withdrawn,
113 • replaced by a revised edition, or
114 • amended.
