AUTOMATIC ELECTRICAL CONTROLS –

Part 2-13: Particular requirements for humidity 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 60730-2-13 has been prepared by IEC technical committee 72:
Automatic electrical controls.
This bilingual version (2018-04) corresponds to the monolingual English version, published in
2017-10.
The text of this standard is based on the following documents:
FDIS Report on voting
72/1078/FDIS 72/1108/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.
The French version of this standard has not been voted upon.

– 4 – IEC 60730-2-13:2017 © IEC 2017
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
This third edition cancels and replaces the second edition published in 2006. 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:
a) alignment of the EMC requirements in Clause H.26 to those in other part 2 standards;
b) addition of requirements in Clause H.27 to cover class B and C control functions of
humidity sensing controls.
This Part 2-13 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 2-13 supplements or modifies the corresponding clauses in IEC 60730-1, so as to
convert that publication into the IEC standard: Particular requirements for humidity sensing
controls.
Where this Part 2-13 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 2-13 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.
In this publication, the following print types are used:
• Requirements proper: in roman type.
• Test specifications: in italic type.
• Explanatory matter: in smaller roman type.
Subclauses, notes or items 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, under the general title Automatic electrical controls
can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

d) The control shall continue to operate as intended.
Replace the last sentence with the following:
The fault reaction time shall be declared by the manufacturer (see Table 1, requirement 91).
For permanent operation as declared by the manufacturer (see Table 1, requirement 103),
item c) is under consideration.
For a control function, where a mechanical actuator is part of a circuit that characterizes the
defined state, a test up to, but not including, the switching contacts is sufficient. If the test of
the defined state fails, the control shall initiate the safety shut-down. Frequency of test is
as declared by the manufacturer (see Table 1, requirement 102). Internal faults of the
components of the checking circuits are not considered.
H.27.1.2.3.3 Second fault
Modification:
Replace second sentence and items a) and b) with the following:
During assessment, for systems with non-permanent operation, the second fault shall only
be considered to occur when a start-up sequence has been performed after the first fault. For
systems with permanent operation, the second fault occurs 24 h after the first fault.
Replace the last two sentences with the following:
The fault reaction time, as well as the applicability of c), shall be as declared by the
manufacturer.
For a control function, where a mechanical actuator is part of a circuit that characterizes the
defined state, a test up to, but not including, the switching contacts is sufficient. If the test of
the defined state fails, the control shall initiate the safety shut-down. Frequency of test is
as declared by the manufacturer (see Table 1, requirement 102). Internal faults of the
components of the checking circuits are not considered.

For all controls, the test is to be conducted with (50 ± 20) % ON time. A humidity operated control is to be
so tested, using a slow rate of change.
c
Tested without current, cycle rate may be at any convenient speed.

17.16.101 Addition:
If a control has two or more electrical ratings (for example, inductive and resistive, or
different currents at different voltages), it may be tested for not less than 25 % of its declared
endurance (if equal to or greater than 30 000 cycles) at each rating, but the total number of
cycles on any one sample is not to be more than its declared endurance. However, at least
one sample shall be tested for a total number of cycles equal to its declared endurance.
