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 60669‑2‑31).
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.
1.1.2 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.
