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 1) .
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.

EN 60730-2-7:2010 (E)

1.1.3 This standard applies to automatic electrical control devices serving the starting of
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.

A Type 1.S or 2.S action shall be so designed that, after interruption of the electrical supply for any
interval up to the declared period of power reserve, it resumes its intended operating sequence as if no
interruption of the supply has occurred.
Compliance is checked by a switching operation, carried out immediately after a given period of power
reserve. The power reserve shall be obtained at a voltage equal to 0,85 times rated voltage and 1,1
times rated voltage. Each test shall be carried out once after a complete wind-up of the time switch.

Test sequence and conditions
Addition:

For manual actions which have been tested during the tests of 17.7 and 17.8, the number of
cycles of actuation is reduced by the number of cycles carried out during those tests.
If a clutch is used during the tests of 17.10 to 17.13 inclusive, care should be taken to ensure

that it does not fail due to the acceleration. If it fails or is considered liable to fail, the speeds
of actuation shall be as specified, but rest periods shall be introduced between cycles to allow
the heat dissipation which would occur during normal use.
Additional subclause:
17.1.3.101 At the end of each cycle, for timers only, an appropriate actuation shall be
performed to initiate the next cycle.
If a timer or time switch has different programs, that program which utilizes the maximum
number of contact operations shall be chosen, unless a timer with a special test program has
been submitted by the manufacturer.
If the program does not cause all the contacts to be operated, the test shall be repeated on a
new set or sets of samples operating on other programs to ensure that all contacts are tested.
These extra samples need not be tested where the design is such that the results can be
reasonably predicted from the result of the first set of samples, as could be done if the design
of all contacts were identical.


BS EN 60730-2-7:2010
EN 60730-2-7:2010 (E)

– 12 –

If a timer with a special test program is used, it shall be so designed that it is possible, by
carrying out the special program, to reasonably predict the test results for all specific
application programs of the timer.
In-line cord, free-standing and independently mounted controls shall be tested as follows.
–

For timers declared for resistive load, the number of cycles of contact operation for each
contact of the time switch shall be A = 5 000.
The number of cycles of actuation (M) for each manual action of the time switch shall be

M = 500 (inducing 500 cycles of contact operation).

–

For timers declared for resistive or inductive load, the number of cycles of contact
operation for each contact so rated shall be 5 000, consisting of a first number of cycles
A = 2 500, to be tested with a substantially resistive load as specified in Table 17.2-1,
ˆText deleted‰ followed by a second number of cycles, A = 2 500, which shall be
conducted at the conditions specified in Table 17.2-1 ˆText deleted‰ , for resistive or
inductive load.
The number of cycles of actuation (M) for each manual action of these timers shall be
M = 500 (inducing 500 cycles of contact operation, tested under resistive load conditions).

–

If the timer requires an external electrical or mechanical signal to move it from a rest
position this shall be simulated, if necessary in the manner declared by the manufacturer.

–

For timers and time switches with Type 2 actions, any electrically driven prime mover shall
for at least 50 % of the test, be connected to a supply of 0,9 V R , all other loads and
connections remaining as in 17.7.

–

For timers and time switches with Type 1 actions, if there is any failure attributable to the
acceleration (such as the excessive use of a clutch), then the test is held to be invalid and
should be repeated in another manner.

17.16.101 Tungsten-filament lamp loads
17.16.101.1 Timers classified by the manufacturer under 6.2.3, declared specific load, for
tungsten-filament lamp load with a rating as declared according to Table 7.2, requirement 7,
are submitted to the test tungsten-filament lamp test of 18.2 of IEC 60669-1, with the number
of contact cycles as declared by the manufacturer. The operating cycle shall be such that the
lamps are off for at least 55 s of each test cycle.
Timers classified for use with tungsten-filament lamp loads are tested at rated voltage and at
no less than 1,2 times the rated current.
The test is carried out by using a number of 200 W tungsten-filament lamps. If such lamps
with rated voltage equal to the rated voltage of the timer are not available, lamps with the
nearest lower voltage can be used but should not be lower than 95 % of the rated voltage of
the timer, if possible.
The test voltage shall be the rated voltage of the lamps.
The number of lamps shall be the smallest number giving a test current not less than 1,2
times the rated current of the timer.
The operating cycle shall be such that the lamps are off for at least 55 s of each test cycle.
The number of operations shall be as declared.
The available short-circuit current of the supply shall be at least 1 500 A.

During the test, no sustained arcing shall occur at the contacts of the samples and after the
test they shall show no damage which may impair their further use.
