Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-030: Particular requirements for equipment having testing or measuring circuits
IEC 61010-2-030:2023 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. This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) in 1.2.1, requirements for protection against hazards which could occur from reading a voltage have been added to the scope;
b) Clause 2, all normative references have been dated and new normative references have been added;
c) in 4.3.2.5, requirements for power supply have been modified;
d) in 4.3.2.6, requirements for inputs/outputs have been modified;
e) in 4.4.2.101, a new subclause about surge protective devices has been added;
f) in 5.1.5.101.2, minimum ratings for voltage of measuring terminals are required;
g) Subclause 6.6.101 modifies 6.6.101 and 6.6.102 of previous edition:
1) in 6.6.101.1, insulating material of group I may be allowed for determination of creepage distances of measuring circuit terminals;
2) In 6.6.101.2, clearances and creepage distances up to 3 000 V for measuring circuit terminals in unmated position have been defined;
3) in 6.6.101.3, requirements for measuring circuit terminals in partially mated position have been specified;
4) in 6.6.101.4, requirements for measuring circuit terminals in mated position have been specified;
5) Subclause 6.6.101.5 replaces 6.6.102;
h) Subclause 9.101 to consider the protection of measuring circuits against the spread of fire and arc flash has been added and Table 102 has been replaced by Table K.101;

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
66/497A/ISH 66/505/RVD
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.
