1 Scope and normative references
In general, this part of IEC 60730 applies to automatic
for use in, on, or in association with equipment for household and similar use. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof.
NOTE 1 Throughout this standard the word "equipment" means "appliance and equipment."
for appliances within the scope of IEC 60335.
This International Standard is applicable to
for building automation within the scope of ISO 16484.
This standard also applies to automatic
for equipment that may be used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications.
for commercial catering, heating and air-conditioning equipment.
This standard is also applicable to individual
utilized as part of a
which are mechanically integral with multifunctional
having non-electrical outputs.

in smart grid systems and
for building automation systems within the scope of ISO 16484-2.
This standard is also applicable to relays when used as
for IEC 60335 appliances. Additional requirements for the safety and
of relays when used as
for IEC 60335 appliances are contained in Annex U.
NOTE 2 These requirements are referred to in the scope of IEC 61810-1.
NOTE 3 This standard is intended to be used for the testing of any stand-alone relay which is intended to be used as a
of an appliance according to IEC 60335-1. It is not intended to be used for any other stand-alone relay, or to replace the IEC 61810 series of standards.
This standard does not apply to automatic
intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard.
This standard applies to
powered by primary or secondary batteries, requirements for which are contained within the standard, including Annex V.
1 1.1 This International Standard applies to the inherent safety, to the
where such are associated with equipment safety, and to the testing of automatic
devices used in, or in association with, equipment.
This standard applies to

This standard is also applicable to the
LOW COMPLEXITY SAFETY RELATED SYSTEMS
1 1.2 This standard applies to automatic
, mechanically or electrically operated, responsive to or controlling such characteristics as temperature, pressure, passage of time, humidity, light, electrostatic effects, flow, or liquid level, current, voltage, acceleration, or combinations thereof.
1 1.3 This standard applies to starting relays, which are a specific type of automatic
, intended to switch the starting winding of a motor. Such
may be built into, or be separate from, the motor.
1 1.4 This standard applies to
when such are electrically and/or mechanically integral with

are contained in IEC 61058-1.
1 1.5 This standard applies to a.c. or d.c. powered
with a rated voltage not exceeding 690 V a.c. or 600 V d.c.
1 1.6 This standard does not take into account the

is dependent upon the method of mounting the
in the equipment. Where a
is of significant purpose for the protection of the
, or surroundings, the value defined in the appropriate household equipment standard or as determined by the manufacturer shall apply.
1 1.7 This standard applies also to
, requirements for which are contained in Annex H.
Modification of 7 by adding the following text:
This standard applies to discrete
and also to controls using

1 1.8 This standard applies also to
, requirements for which are contained in Annex J.
1 1.9 This standard applies to the electrical and
capable of receiving and responding to communications signals, including signals for power billing rate and demand response.
The signals may be transmitted to or received from external units being part of the
(wired), or to and from external units which are not part of the
(wireless) under test.
1 1.10 This standard does not address the integrity of the output signal to the network devices, such as interoperability with other devices unless it has been evaluated as part of the
Addition to the Scope by adding the following text:
intended to be installed in air handling spaces or in other environmental air space (plenums) are covered under the scope of this standard.
