39 SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT FOR
40 MEASUREMENT, CONTROL, AND LABORATORY USE –
42 Part 2-020: Particular requirements for LABORATORY CENTRIFUGES
44 FOREWORD
45 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
46 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
47 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
48 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
49 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
50 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
51 in the subject dealt with may participate in this preparatory work. International, governmental and non -
52 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
53 with the International Organization for Standardization (ISO) in accordance with conditions determined by
54 agreement between the two organizations.
55 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
56 consensus of opinion on the relevant subjects since each technical committee has representation from all
57 interested IEC National Committees.
58 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
59 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
60 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
61 misinterpretation by any end user.
62 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
63 transparently to the maximum extent possible in their national and regional publications. Any divergence
64 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
65 the latter.
66 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
67 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
68 services carried out by independent certification bodies.
69 6) All users should ensure that they have the latest edition of this publication.
70 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
71 members of its technical committees and IEC National Committees for any personal injury, property damage or
72 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
73 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
74 Publications.
75 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
76 indispensable for the correct application of this publication.
77 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
78 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
79 International Standard IEC 61010-2-020 has been prepared by IEC technical committee 66:
80 Safety of measuring, control and laboratory equipment.
81 This fourth edition cancels and replaces the third edition published in 2016. This edition
82 constitutes a technical revision.
83 This edition includes the following significant technical changes with respect to the previous
84 edition:
85 a) alignment with changes introduced by Amendment 1 of IEC 61010-1:2010.
86 It has the status of a product safety publication in accordance with IEC Guide 104.
87 The text of this International Standard is based on the following documents:

66/820/CDV – 4 – IEC CDV 61010-2-020 © IEC 2024
CDV Report on voting
66/xxx/CDV 66/xxx/RVC
89 Full information on the voting for the approval of this International Standard can be found in
90 the report on voting indicated in the above table.
91 This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
92 A list of all parts of the IEC 61010 series, published under the general title Safety
93 requirements for electrical equipment for measurement, control, and laboratory use , can be
94 found on the IEC website.
95 This Part 2-020 is intended to be used in conjunction with the latest edition of IEC 61010-1. It
96 was established on the basis of the third edition (2010) and its Amendment 1 (2016),
97 hereinafter referred to as Part 1.
98 This Part 2-020 supplements or modifies the corresponding clauses in IEC 61010-1 so as to
99 convert that publication into the IEC standard: Particular requirements for LABORATORY
100 CENTRIFUGES.
101 Where a particular subclause of Part 1 is not mentioned in this Part 2-020, that subclause
102 applies as far as is reasonable. Where this Part 2-020 states "addition", "modification" or
103 "replacement", the relevant requirement, test specification or note in Part 1 shall be adapted
104 accordingly.
105 In this standard:
106 1) the following print types are used:
107 – requirements: in roman type;
108 – NOTES: in small roman type;
109 – conformity and tests: in italic type;
110 – terms used throughout this standard which have been defined in Clause 3: SMALL
111 ROMAN CAPITALS.
112 2) subclauses, tables or figures which are additional to those in Part 1 are numbered starting
113 from 101. Additional annexes are lettered starting from AA.
114 The committee has decided that the contents of this document will remain unchanged until the
115 stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
116 the specific document. At this date, the document will be
117 • reconfirmed,
118 • withdrawn,
119 • replaced by a revised edition, or
120 • amended.
