scope:

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.

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.

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.

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.

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.

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.

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.

This standard applies also to CONTROLS incorporating ELECTRONIC DEVICES, requirements for which are contained in Annex H.

D2 Modification of 1.1.7 by adding the following text:

This standard applies to discrete THERMISTORS and also to controls using NTC or PTC THERMISTORS, requirements for which are contained in Annex J

This standard applies also to CONTROLS using NTC or PTC THERMISTORS, requirements for which are contained in Annex J.

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.

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.

DR Addition to the Scope by adding the following text:

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

This part of IEC 60730 applies to controls for automatically controlling the starting windings of single phase motors associated with equipment for household and similar use.

This standard applies to motor-starting relays using NTC or PTC thermistors, additional requirements for which are contained in Annex J.

D2 Addition of the following text to 1.1:

This standard also covers centrifugal switches intended to be integrated into motors. Such devices are tested with the intended motor as an integrated control.

This 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 motor starting relays used in, or in association with, household or similar equipment.

Motor-starting relays 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 does not apply to motor-starting relays designed exclusively for industrial applications.

Throughout this standard, the word ″equipment″ means ″appliance and equipment.″ The words ″starting relay″ mean ″motor-starting relay.″

This standard applies to starting relays incorporating electronic devices, and starting relays using thermistor elements, thermal elements and magnetic elements.

This standard does not apply to general purpose relays or to contactors and motor starters of the type covered by the IEC 60947 series1). This standard does not apply to mechanical TIMERS or mechanically operated motor-starting devices.

D2 Deletion of the following text from the second sentence of 1.1.3:

″or mechanically operated motor-starting devices″

1) IEC 60947 (all parts), Low-voltage switchgear and controlgear

This standard applies to MANUAL CONTROLS when such are electrically and/or mechanically integral with starting relays.

Requirements for manual switches not forming part of a starting relay are contained in IEC 61058-1.

This standard applies to starting relays with a RATED VOLTAGE not exceeding 690 V and with a RATED CURRENT not exceeding 63 A.

D2 Addition of the following text to 1.2:

The maximum voltage is 600 V. The maximum current is unlimited.

This standard does not take into account the RESPONSE VALUE of an AUTOMATIC ACTION of a starting relay, if such a RESPONSE VALUE is dependent upon the method of mounting the starting relay 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.

This standard applies also to motor-starting relays incorporating electronic devices, requirements for which are contained in annex H.
