- Protection against electric shock: Basic, supplementary and reinforced insulation; protective bonding; limits for accessible parts; testing in a SINGLE FAULT CONDITION.
- Measuring circuit terminals: New and revised rules for clearances and creepage - defined for unmated, partially mated and mated positions, including values up to 3 000 V and new minimum voltage ratings for measuring terminals.
- Surge and transient protection: Addition of requirements and tests for surge protective devices (reference to IEC 61000-4-5 for surge tests).
- Fire and arc‑flash protection: New subclause to consider spread of fire and arc flash from measuring circuits; related tables updated (Table K.101 and others).
- Constructional & testing requirements: Updated reference test conditions, sequence of tests, voltage test procedures, insulation testing, and requirements for power supply, inputs/outputs and connectors.
- Methods & annexes: Revised methods for determining clearances, determination of Ut for circuits that reduce transient overvoltages, plus updated informative annexes (AA, EE) and extensive updates in Clause K.
Practical applications and users
This standard is essential for:
- Equipment designers and manufacturers of multimeters, insulation testers, oscilloscopes, bench instruments, test fixtures and laboratory analyzers.
- Safety engineers and compliance teams preparing CE/CB/IECEE documentation or performing risk assessments and type testing.
- Test labs and certification bodies evaluating electrical safety of measuring and test equipment.
- System integrators and maintenance professionals ensuring safe connections between measurement equipment and external circuits.
Using IEC 61010-2-030:2023 helps ensure safe operator protection, consistent terminal ratings and robust immunity against transients, arc flash and fire risks when measuring or testing live circuits.

INTERPRETATION SHEET 1
This interpretation sheet has been prepared by IEC technical committee 66: Safety of
measuring, control and laboratory equipment.
The text of this interpretation sheet is based on the following documents:
ISH Report on voting

Full information on the voting for the approval of this interpretation sheet can be found in the
report on voting indicated in the above table.
___________
IEC 61010-1:2010 contains a requirement in 6.8.3.1 pertaining to voltage testers for type tests
as follows:
“The generator shall be able to supply a power of at least 500 VA.”
This has given rise to the following questions:
How does one interpret the requirement for voltage testers in 6.8.3.1 of IEC 61010-1:2010?
Specifically, this subclause requires that “The generator shall be able to supply a power of at
least 500 VA.” Does this requirement apply throughout the rated output range of the voltage
tester? What is meant by the word “generator”? Is the “generator” the power supply within the
voltage tester, or the voltage tester output, or something else?
Interpretation:
“A voltage tester used for type tests must be able to deliver at least 500 VA at its full-rated
output voltage. It does not necessarily need to deliver 500 VA if set for lower voltages.
For example, a voltage tester that can deliver 100 mA at any test output voltage up to 5 000 V
(and a current corresponding to 500 VA above 5 000 V) would meet the requirement.
The requirements for voltage testers used for routine (production line) tests are included in
Annex F. The requirements of 6.8.3.1 do not apply to these voltage testers.”

SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
Part 2-030: Particular requirements for equipment
having testing or measuring circuits
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 of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
IEC 61010-1 specifies the safety requirements that are generally applicable to all equipment
within its scope. For certain types of equipment, the requirements of IEC 61010-1 and its
amendment will be supplemented or modified by the special requirements of one or more
standard from the IEC 61010-2 series which is/are read in conjunction with the requirements of
IEC 61010-1.
1) This document specifies the safety requirements for equipment with testing or measuring
circuits which are connected for test or measurement purposes to devices or circuits outside
the measurement equipment itself.
2) IEC 61010-2-032:2023 specifies the safety requirements for hand-held and hand-
manipulated current sensors for measuring, detecting, injecting current, or indicating current
waveforms on circuits without physically opening the current path of the circuit being
measured.
Most of the requirements of this document have been included in IEC 61010-2-032:2023.
Equipment within the scopes of both this document and IEC 61010-2-032:2023 is
considered to be covered by the requirements of IEC 61010-2-032:2023.
However, for current sensors in combined equipment with protective bonding and automatic
disconnection of the supply, this document and IEC 61010-2-032:2023 are read in
conjunction.
3) IEC 61010-2-033:2023 specifies the safety requirements for hand-held multimeters and
other meters for domestic and professional use, capable of measuring mains voltage,
intended to measure voltage and other electrical quantities such as resistance or current.
All relevant requirements of this document have been included in IEC 61010-2-033:2023.
4) IEC 61010-2-034:2023 specifies the safety requirements for measurement equipment for
insulation resistance and test equipment for electric strength which are connected to units,
lines or circuits for test or measurement purposes.
All relevant requirements of this document have been included in IEC 61010-2-034:2023.
However, for equipment within the scope of IEC 61010-2-032:2023 and
IEC 61010-2-034:2023, these standards are read in conjunction.
IEC 61010-031 specifies the safety requirements for hand-held and hand-manipulated probe
assemblies and their related accessories intended to be used in particular with equipment in
the scope of this document, IEC 61010-2-032, IEC 61010-2-033 and IEC 61010-2-034. These
probe assemblies are for non-contact or direct electrical connection between a part and
electrical test and measurement equipment. They may be fixed to the equipment or be
detachable accessories for the equipment.

IEC 61010-1:2010, Clause 1 and IEC 61010-1:2010/AMD1:2016, Clause 1 apply except as
follows:
1.1.1 Equipment included in scope
Replace the existing text with the following:
This document specifies safety requirements for equipment having testing or measuring circuits
which are connected for test or measurement purposes to devices or circuits outside the
measurement equipment itself.
These include measuring circuits which are part of electrical test and measurement equipment,
laboratory equipment, or process control equipment. These circuits in equipment have
additional protective means between the circuit and an OPERATOR.
NOTE These testing and measuring circuits can, for example:
– measure voltages in circuits of other equipment,
– measure temperature of a separate device via a thermocouple,
– measure force on a separate device via a strain gauge,
– inject a voltage or current onto a circuit to analyse or test a new design.
This group safety publication focusing on safety essential requirements is primarily intended to
be used as a product safety standard for the products mentioned in the scope, but is also
intended to be used by technical committees in the preparation of publications for products
similar to those mentioned in the scope of this document, in accordance with the principles laid
down in IEC Guide 104 and lSO/lEC Guide 51.
One of the responsibilities of a technical committee is, wherever applicable, to make use of
basic safety publications and/or group safety publications in the preparation of its publications.
1.2.1 Aspects included in scope
Replace item c) of the second paragraph with the following new item c):
c) spread of fire or arc flash from the equipment (see Clause 9);
Replace the third paragraph with the following two new paragraphs:
Requirements for protection against HAZARDS arising from NORMAL USE, REASONABLY
FORESEEABLE MISUSE and ergonomic factors are specified in Clause 16 and Clause 101.
