UL 60730-1:2021

1 Scope and normative references

In general, this part of IEC 60730 applies to automatic

ELECTRICAL CONTROLS

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."

EXAMPLE 1

CONTROLS

for appliances within the scope of IEC 60335.

This International Standard is applicable to

CONTROLS

for building automation within the scope of ISO 16484.

This standard also applies to automatic

ELECTRICAL CONTROLS

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.

EXAMPLE 2

CONTROLS

for commercial catering, heating and air-conditioning equipment.

This standard is also applicable to individual

CONTROLS

utilized as part of a

CONTROL

system or

CONTROLS

which are mechanically integral with multifunctional

CONTROLS

having non-electrical outputs.

EXAMPLE 3 Independently mounted water valves,

CONTROLS

in smart grid systems and

CONTROLS

for building automation systems within the scope of ISO 16484-2.

This standard is also applicable to relays when used as

CONTROLS

for IEC 60335 appliances. Additional requirements for the safety and

OPERATING VALUES

of relays when used as

CONTROLS

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

CONTROL

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

ELECTRICAL CONTROLS

intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard.

This standard applies to

CONTROLS

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

OPERATING VALUES

,

OPERATING TIMES

, and

OPERATING SEQUENCES

where such are associated with equipment safety, and to the testing of automatic

ELECTRICAL CONTROL

devices used in, or in association with, equipment.

This standard applies to

CONTROLS

using

THERMISTORS

, see also Annex J.

This standard is also applicable to the

FUNCTIONAL SAFETY

of

LOW COMPLEXITY SAFETY RELATED SYSTEMS

and

CONTROLS

.

1 1.2 This standard applies to automatic

ELECTRICAL CONTROLS

, 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

ELECTRICAL CONTROL

, intended to switch the starting winding of a motor. Such

CONTROLS

may be built into, or be separate from, the motor.

1 1.4 This standard applies to

MANUAL CONTROLS

when such are electrically and/or mechanically integral with

AUTOMATIC CONTROLS

.

NOTE Requirements for manual switches not forming part of an

AUTOMATIC CONTROL

are contained in IEC 61058-1.

1 1.5 This standard applies to a.c. or d.c. powered

CONTROLS

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

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. Where a

RESPONSE VALUE

is of significant purpose for the protection of the

USER

, 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

CONTROLS

incorporating

ELECTRONIC DEVICES

, requirements for which are contained in Annex H.

This standard applies to discrete

THERMISTORS

and also to controls using

NTC

or

PTC

THERMISTORS

, requirements for which are contained in Annex J

1 1.8 This standard applies also to

CONTROLS

using

NTC

or

PTC

THERMISTORS

, requirements for which are contained in Annex J.

1 1.9 This standard applies to the electrical and

FUNCTIONAL SAFETY

of

CONTROLS

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

CONTROL

(wired), or to and from external units which are not part of the

CONTROL

(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

CONTROL SYSTEM

.

CONTROLS

intended to be installed in air handling spaces or in other environmental air space (plenums) are covered under the scope of this standard.
