58 SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
59 FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
61 Part 2-030: Particular requirements for equipment
62 having testing or measuring circuits
64 FOREWORD
65 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
66 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
67 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
68 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
69 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
70 preparation is entrusted to technical committees; any IEC National Committee interested in the subject de alt with
71 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
72 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
73 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
74 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
75 consensus of opinion on the relevant subjects since each technical committee has representation from all
76 interested IEC National Committees.77 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
78 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
79 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
80 misinterpretation by any end user.81 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
82 transparently to the maximum extent possible in their national and regional publications. Any divergence between
83 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
84 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
85 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
86 services carried out by independent certification bodies.87 6) All users should ensure that they have the latest edition of this publication.
88 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
89 members of its technical committees and IEC National Committees for any personal injury, property damage or
90 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
91 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
92 Publications.93 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
94 indispensable for the correct application of this publication.95 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
96 rights. IEC shall not be held responsible for identifying any or all such patent rights.
97 IEC 61010-2-030 has been prepared by IEC technical committee 66: Safety of measuring,
98 control and laboratory equipment.99 It has the status of a group safety publication in accordance with IEC Guide 104.
100 This third edition cancels and replaces the second edition published in 2017. This edition
101 constitutes a technical revision.---------------------- Page: 6 ----------------------

146 INTRODUCTION
147 IEC 61010-1 specifies the safety requirements that are generally applicable to all equipment
148 within its scope. For certain types of equipment, the requirements of IEC 61010-1 and its
149 amendment will be supplemented or modified by the special requirements of one, or more than
150 one, particular Part 2 which are read in conjunction with the Part 1 requirements.
151 1) Part 2-030 specifies the safety requirements for equipment with testing or measuring
152 circuits which are connected for test or measurement purposes to devices or circuits outside
153 the measurement equipment itself.154 2) Part 2-032 specifies the safety requirements for hand-held and hand-manipulated current
155 sensors for measuring, detecting, injecting current, or indicating current waveforms on
156 circuits without physically opening the current path of the circuit being measured.
157 Most of the requirements of Part 2-030 have been included into Part 2-032. Equipment
158 within the scopes of both Part 2-030 and Part 2-032 are considered to be covered by the
159 requirements of Part 2-032.160 However, for current sensor in combined equipment with protective bonding and automatic
161 disconnection of the supply, Part 2-030 and Part 2-032 are read in conjunction
162 3) Part 2-033 specifies the safety requirements for hand-held multimeters and other meters for
163 domestic and professional use, capable of measuring mains voltage, intended to measure
164 voltage and other electrical quantities such as resistance or current.165 All relevant requirements of Part 2-030 have been included into Part 2-033.
166 4) Part 2-034 specifies the safety requirements for measurement equipment for insulation
167 resistance and test equipment for electric strength which are connected to units, lines or
168 circuits for test or measurement purposes.169 All relevant requirements of Part 2-030 have been included into Part 2-034. However, for
170 equipment within the scope of Part 2-032 and Part 2-034, these standards are read in
171 conjunction.172 IEC 61010-031 specifies the safety requirements for hand-held and hand-manipulated probe
173 assemblies and their related accessories intended to be used in particular with equipment in
174 the scope of Part 2-030, Part 2-032, Part 2-033 and Part 2-034. These probe assemblies are
175 for non-contact or direct electrical connection between a part and electrical test and
176 measurement equipment. They may be fixed to the equipment or be detachable accessories for
177 the equipment.178

189 follows:190 1.1.1 Equipment included in scope
191 Replace the existing text with the following:
192 This group safety publication is primarily intended to be used as a product safety standard for
193 the products mentioned in the scope, but shall also be used by technical committees in the
194 preparation of their publications for products similar to those mentioned in the scope of this
195 document, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51.
196 This part of IEC 61010 specifies safety requirements for equipment having testing or measuring
197 circuits which are connected for test or measurement purposes to devices or circuits outside
198 the measurement equipment itself.199 These include measuring circuits which are part of electrical test and measurement equipment,
200 laboratory equipment, or process control equipment. The existence of these circuits in
201 equipment requires additional protective means between the circuit and an OPERATOR.
202 NOTE These testing and measuring circuits can, for example:203 – measure voltages in circuits of other equipment,
204 – measure temperature of a separate device via a thermocouple,
205 – measure force on a separate device via a strain gauge,
206 – inject a voltage onto a circuit to analyse a new design.

208 Replace item c) of the second paragraph with the following new item:
209 c) spread of fire or arc flash from the equipment (see Clause 9);
210 Replace the third paragraph with the following two new paragraphs:
211 Requirements for protection against HAZARDS arising from NORMAL USE, REASONABLY
212 FORESEEABLE MISUSE and ergonomic factors are specified in Clause 16 and Clause 101.
