Na splošno ta del IEC 60730 velja za stikalne ure in časovna stikala za gospodinjstva in podobno uporabo, ki lahko porabljajo elektriko, plin, nafto, trdno gorivo, solarno termalno energijo ali njihove kombinacije, vključno z ogrevanjem, prezračevanjem in podobnimi rabami. Ta standard prav tako velja za posamične stikalne ure, uporabljene kot del nadzornega sistema ali stikalne ure, ki so mehansko združene v večfunkcijske krmilne naprave, z priključki, ki niso električni.  Ta standard ne velja za stikala s časovno zakasnitvijo (TDS) znotraj področja uporabe IEC 60669-2-3. V tem standardu besedna zveza »stikalne ure« pomeni stiskalne ure in časovna stikala, razen če je vrsta posebej omenjena. Naprave, ki kažejo zgolj čas ali minevanje časa, niso vključene. Ta standard ne velja za večfunkcijske krmilne naprave, ki imajo vgrajeno funkcijo za izbiro časa, ki je ni možno preskusiti kot ločeno napravo za izbiro časa.

AUTOMATIC ELECTRICAL CONTROLS
FOR HOUSEHOLD AND SIMILAR USE –
Part 2-7: Particular requirements for timers and time switches
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

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 60730-2-7 has been prepared by IEC technical committee 72:

Automatic controls for household use.

This second edition cancels and replaces the first edition published in 1990 and its

Amendment 1 (1994). This second edition constitutes a technical revision. This new edition

incorporates requirements for tungsten filament lamp loadings as well as updates the

standard to IEC 60730-1:1999, Amendment 2 (2007).
The text of this standard is based on the following documents:
FDIS Report on voting
72/760/FDIS 72/764/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

This Part 2-7 is to be used in conjunction with IEC 60730-1. It was established on the basis of

the third edition of that standard (1999) and its Amendment 1 (2003) and Amendment 2

(2007). Consideration may be given to future editions of, or amendments to, IEC 60730-1.

This Part 2-7 supplements or modifies the corresponding clauses in IEC 60730-1 so as to

convert that publication into the IEC standard: Particular requirements for timers and time

switches.

Where this Part 2-7 states "addition", "modification" or "replacement", the relevant require-

ment, test specification or explanatory matter in Part 1 should be adapted accordingly.

Where no change is necessary, this Part 2-7 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 practice are contained in the following clauses and

subclauses:
– 4.1.4

AUTOMATIC ELECTRICAL CONTROLS
FOR HOUSEHOLD AND SIMILAR USE –
Part 2-7: Particular requirements for timers and time switches
1 Scope and normative references
This clause of Part 1 is applicable except as follows:
1.1 Replacement:

In general, this part of IEC 60730 applies to timers and time switches for household and

similar use that may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a

combination thereof, including heating, air conditioning and similar applications.

This standard is also applicable to individual timers utilized as part of a control system or

timers which are mechanically integral with multifunctional controls having non-electrical

outlets. This standard does not apply to time-delay switches (TDS) within the scope of

IEC 60669-2-3 .

Throughout this standard, the word “timers” means timers and time switches, unless the type is specifically

mentioned.
Devices which only indicate time or passage of time are not included.

This standard does not apply to multi-functional controls having an integrated timing function which is not capable

of being tested as a separate timing device.

1.1.1 This standard applies to the inherent safety, to the operating characteristics where

such are associated with equipment protection and to the testing of automatic electrical

control devices used in appliances and other apparatus, electrical and non-electrical, for

household and similar purposes, but also extended to industrial purposes when no dedicated

product standards exist, such as that for central heating, air conditioning, process heating,

etc.

Timers for equipment not intended for normal household use, but which nevertheless may be

used by the public, such as equipment intended to be used by laymen in shops, in light

industry and on farms, are within the scope of this standard.

This standard is also applicable to timers for appliances within the scope of IEC 60335-1.

This standard does not apply to timers designed exclusively for industrial applications.

Throughout this standard, the word "equipment" means "appliance and equipment".

1.1.2 This standard applies to automatic electrical control devices, mechanically,

electromechanically, electrically or electronically operated, responsive to or controlling

parameters such as temperature, pressure, passage or time, humidity, light, electrostatic

effect, flow or liquid level.

small motors that are used principally in appliances and apparatus for household and similar

purposes. Such control devices may be built into or be separate from the motor.

1.1.4 This standard applies to non-automatic control devices when such are associated with

automatic control devices.
1.2 Replacement:

This standard applies to controls with a rated voltage not exceeding 690 V and a rated current

not exceeding 63 A.
1.3 Replacement:

This standard does not take into account the response value of an automatic action of a

control, if such a response value is dependent upon the method of mounting the control in the

equipment. If a response value is of significant purpose for the safety of the user or

surroundings, the value defined in the appropriate household equipment standard or as

determined by the manufacturer shall apply.
1.4 Replacement:

This standard applies also to timers incorporating electronic devices, requirements for which

are contained in Annex H.

hand-wound timer
timer or time switch in which the transmission is provided by actuation
3 General requirements
This clause of Part 1 is applicable.
4 General notes on tests
This clause of Part 1 is applicable except as follows:
4.1.4 Addition:

In the USA, the test in 14.101 is conducted first and the remaining tests are carried out in the order of the clauses

of this standard.
4.3.2.1 Addition:

In Canada and the USA, to reduce testing, a timer that is classified for use with motor loads at more than one rated

voltage is to be tested at the current and voltage in Table 17.2-2 corresponding to the highest rated voltage. If the

current in Table 17.2-2 corresponding to a lower rated voltage is greater than 135 % of the current corresponding

to the highest rated voltage, then the timer is also to be tested at the lower rated voltage. The greater current

involved at a lower rated voltage may necessitate a separate heating test under Clause 14. If more than one test is

conducted, one sample is to be used for each test.
