AUTOMATIC ELECTRICAL CONTROLS –
Part 2-9: Particular requirements for temperature sensing controls
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60730-2-9 has been prepared by technical committee TC 72:

Automatic electrical controls.
The text of this standard is based on the following documents:
FDIS Report on voting
72/990/FDIS 72/998/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This fourth edition cancels and replaces the third edition published in 2008, and its

Amendment 1:2011. This edition constitutes a technical revision. This edition includes

alignment with the text of 60730-1 fifth edition and the following significant technical changes

with respect to the previous edition:
---------------------- Page: 10 ----------------------
SIST EN IEC 60730-2-9:2019
IEC 60730-2-9:2015 © IEC 2015 – 5 –
a) modification of heating-freezing tests in Clause 12;
b) alignment of the EMC requirements in H.26 to those in other part 2 standards;

c) addition of requirements in Clause H.27 to cover class B and C control functions of

temperature sensing controls;

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

This Part 2-9 is intended to be used in conjunction with IEC 60730-1. It was established on the

basis of the fifth edition (2013) of that publication. Consideration may be given to future

editions of, or amendments to, IEC 60730-1.

This Part 2-9 supplements or modifies the corresponding clauses in IEC 60730-1 so as to

convert that publication into the IEC standard: Particular requirements for temperature sensing

controls.

Where this Part 2-9 states "addition", "modification", or "replacement", the relevant

requirement, test specification or explanatory matter in part 1 should be adapted accordingly.

Where no change is necessary, this part 2 indicates that the relevant clause or subclause

applies.

In the development of a fully international standard, it has been necessary to take into

consideration the differing requirements resulting from practical experience in various parts of

the world and to recognize the variation in national electrical systems and wiring rules.

The “in some countries” notes regarding differing national practices are contained in the

following subclauses:
4.1.101 17.8.4.101 Annex AA
7.2, Table 1 17.16.101 Clause CC.2
11.4.101 17.16.102 DD.9.2
11.101 17.16.105 EE.3.6
12.101.3 18.102.3
13.2 23.101
In this publication:
1) The following print types are used:
– Requirements proper: in roman type;
– Test specifications: in italic type;
– Notes; in small roman type;
– Words defined in Clause 2: bold.

2) Subclauses, notes, tables and figures which are additional to those in part 1 are numbered

starting from 101, additional annexes are lettered AA, BB, etc.

A list of all parts of the IEC 60730 series, published under the title Automatic electrical controls

can be found on the IEC website.

AUTOMATIC ELECTRICAL CONTROLS –
Part 2-9: Particular requirements for temperature sensing controls
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60730-2-9 has been prepared by technical committee TC 72:

Automatic electrical controls.
The text of this standard is based on the following documents:
FDIS Report on voting
72/990/FDIS 72/998/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This fourth edition cancels and replaces the third edition published in 2008, and its

Amendment 1:2011. This edition constitutes a technical revision. This edition includes

alignment with the text of 60730-1 fifth edition and the following significant technical changes

with respect to the previous edition:
---------------------- Page: 10 ----------------------
SIST EN 60730-2-9:2019
IEC 60730-2-9:2015 © IEC 2015 – 5 –
a) modification of heating-freezing tests in Clause 12;
b) alignment of the EMC requirements in H.26 to those in other part 2 standards;

c) addition of requirements in Clause H.27 to cover class B and C control functions of

temperature sensing controls;

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

This Part 2-9 is intended to be used in conjunction with IEC 60730-1. It was established on the

basis of the fifth edition (2013) of that publication. Consideration may be given to future

editions of, or amendments to, IEC 60730-1.

This Part 2-9 supplements or modifies the corresponding clauses in IEC 60730-1 so as to

convert that publication into the IEC standard: Particular requirements for temperature sensing

controls.

Where this Part 2-9 states "addition", "modification", or "replacement", the relevant

requirement, test specification or explanatory matter in part 1 should be adapted accordingly.

Where no change is necessary, this part 2 indicates that the relevant clause or subclause

applies.

In the development of a fully international standard, it has been necessary to take into

consideration the differing requirements resulting from practical experience in various parts of

the world and to recognize the variation in national electrical systems and wiring rules.

The “in some countries” notes regarding differing national practices are contained in the

following subclauses:
4.1.101 17.8.4.101 Annex AA
7.2, Table 1 17.16.101 Clause CC.2
11.4.101 17.16.102 DD.9.2
11.101 17.16.105 EE.3.6
12.101.3 18.102.3
13.2 23.101
In this publication:
1) The following print types are used:
– Requirements proper: in roman type;
– Test specifications: in italic type;
– Notes; in small roman type;
– Words defined in Clause 2: bold.

2) Subclauses, notes, tables and figures which are additional to those in part 1 are numbered

starting from 101, additional annexes are lettered AA, BB, etc.

A list of all parts of the IEC 60730 series, published under the title Automatic electrical controls
