AUTOMATIC ELECTRICAL CONTROLS –

Part 2-15: Particular requirements for automatic electrical
air flow, water flow and water level 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 60730-2-15 has been prepared by IEC committee 72: Automatic
electrical controls.
This third edition cancels and replaces the second edition published in 2008. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) changes to align with the fifth edition of 60730-1, including the revised title.

The text of this International Standard is based on the following documents:
FDIS Report on voting
72/1080/FDIS 72/1101/RVD

Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 2-15 is intended to be used in conjunction with IEC 60730-1. It was established on
the basis of the fifth edition of that standard (2013). Consideration may be given to future
editions of, or amendments to, IEC 60730-1.
This Part 2-15 supplements or modifies the corresponding clauses in IEC 60730-1 so as to
convert that publication into the IEC standard: Particular requirements for automatic electrical
air flow, water flow and water level sensing controls.
Where this document 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 document indicates that the relevant clause or subclause
of Part 1 applies.
In the development of a fully international standard to cover automatic controls for household
and similar use, 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:
• 10.1.4,
• 12.1.101.
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 in the IEC 60730 series, published under the general title Automatic
electrical controls, can be found on the IEC website.

AUTOMATIC ELECTRICAL CONTROLS –

Part 2-15: Particular requirements for automatic electrical
air flow, water flow and water level 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 60730-2-15 has been prepared by IEC committee 72: Automatic
electrical controls.
This third edition cancels and replaces the second edition published in 2008. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) changes to align with the fifth edition of 60730-1, including the revised title.

The text of this International Standard is based on the following documents:
FDIS Report on voting
72/1080/FDIS 72/1101/RVD

Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 2-15 is intended to be used in conjunction with IEC 60730-1. It was established on
the basis of the fifth edition of that standard (2013). Consideration may be given to future
editions of, or amendments to, IEC 60730-1.
This Part 2-15 supplements or modifies the corresponding clauses in IEC 60730-1 so as to
convert that publication into the IEC standard: Particular requirements for automatic electrical
air flow, water flow and water level sensing controls.
Where this document 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 document indicates that the relevant clause or subclause
of Part 1 applies.
In the development of a fully international standard to cover automatic controls for household
and similar use, 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:
• 10.1.4,
• 12.1.101.
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 in the IEC 60730 series, published under the general title Automatic
electrical controls, can be found on the IEC website.
