Scope and normative references 

In general, this standard applies to automatic ELECTRICAL CONTROLS for use in, on, or in association with equipment for household and similar use, including controls for heating, air-conditioning and similar applications. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof.

This Standard applies to the inherent safety; to the OPERATING VALUEOSP,E RATING TIMESa,n d OPERATING SEQUENCE where such are associated with equipment safety; and to the testing of automatic ELECTRICAL CONTROL devices used in, or in association with, household or similar equipment.

This standard is also applicable to controls for appliances within the scope of IEC 60335-1

Throughout this Standard the word "equipment" means "appliance and equipment."

This standard does not apply to automatic ELECTRICAL CONTROLS intended exclusively for industrial applications.

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.

Automatic ELECTRICAL CONTROLS 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.

See also annex J.

1.1.1D V DE Modification of 1.1.1 by adding the following after the first paragraph:

In IEC terminology, "safety" is defined as an acceptable level of risk. This is consistent with the intention of UL requirements to reduce the risk of fire, shock or injury to persons.

This Standard applies to automatic ELECTRICAL CONTROLmSe, chanically 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 or acceleration.

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.

Requirements for manual switches not forming pari of an AUTOMATIC CONTROL are contained in IEC 61058-1

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

1.2DV.1 D2 Modification of 1.2 by adding the following text:

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

1.2DV.2 D1 Addition of 1.2DV.2.1 to 1.2DV.2.3:

1.2DV.2.1 Controls intended for connection to ISOLATED LIMITED SECONDARY CIRCUITS operating at a voltage between conductors or between a conductor and earth not exceeding 42,4 V a. c. peak, or 60 V d. c., are not subject to the requirements of this Standard.

1.2DV.2.2 However, such controls, where they are associated with the safety of the controlled equipment; such as cut-outs; burner control systems; fuel valves and the like; shall be subject to the requirements of this Standard.

1.2DV.2.3 For the purposes of this requirement the ISOLATED LIMITED SECONDARY CIRCUIT shall have a capacity of 100 V A or less and shall be:

a) Inherently limited to such that the output current under any condition of load, including short circuit is not more than 8 A after I-minute of OPERATION if the source is a. c. or the open-circuit voltage is 0-30 V d. c.; and not more than 150/ Vmax, amperes where Vmax, is the open-circuit voltage over 30 V but less than or equal to 60 V d.c., or

b) Provided with a protective device rated 5 A if the open-circuit voltage is O-21,2 V or 3,2 A if the open-circuit voltage is greater than 21,2 and less than or equal to 42,4 V.

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 USERo,r 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 DEVICErSe,q uirements for which are contained in annex H. This standard applies also to controls using NTC or PTC THERMISTOreRqSu,i rements for which are contained in annex J.

This part 2-14 applies to ELECTRIC ACTUATORS 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 Throughout this standard part 2 the word "equipment" means "appliance and equipment."

EXAMPLE 1 ELECTRIC ACTUATORS 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 part 2-14 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 part 2-14 is also applicable to individual ELECTRIC ACTUATORS 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 part 2-14 does not apply to automatic ELECTRIC ACTUATORS intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard.

This part 2-14 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 ELECTRIC ACTUATORS used or in association with equipment

NOTE Requirements for specific OPERATING VALUES, OPERATING TIMES and OPERATING SEQUENCES may be given in the standards for appliances and equipment.

This standard is also applicable to the FUNCTIONAL SAFETY of LOW COMPLEXITY SAFETY RELATED SYSTEMS and CONTROLS.

This part 2-14 does not apply to ELECTRIC ACTUATORS which are mechanically integrated with valves covered by a separate part 2, e.g. IEC 60730-2-8.

This part 2-14 does not apply to electric motors, requirements for which are contained in IEC 60034.

1.1.1DV.2 DC Replacement of third and fourth paragraphs of 1.1.1 with the following:

This part 2 does not apply to electric actuators which are mechanically integrated with valves. See UL 60730-2-8, Particular requirements for electrically operated valves, including mechanical requirements or the Standard for Electrically Operated Valves, UL 429.

This part 2 does not apply to electric motors, requirements for which are contained in UL 1004 series of standards.

1.1.1DV.4 DR Modification of 1.1.1 by adding the following paragraph:

Electric actuators intended for plenum use are covered under the scope of this standard.

Requirements for manual switches not integral with an ELECTRIC ACTUATOR are contained in IEC 61058-1.

1.1.2DV.1 DC Replacement of 1.1.2 with the following:

Requirements for manual switches not integral with an electric actuator are contained in UL 61058-1.

Replacement

This part 2-14 applies to a.c. or d.c. powered ELECTRIC ACTUATORS with a rated voltage not exceeding 690 V a.c. or 600 V d.c.

1.1.3DV.1 D2 Modification of 1.1.3 by adding the following text:

The maximum current is unlimited.

Replacement:

This part 2-14 does not take into account the RESPONSE VALUE of an AUTOMATIC ACTION of an ELECTRIC ACTUATOR, if such a RESPONSE VALUE is dependent upon the method of mounting the ELECTRIC ACTUATOR 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 or as determined by the manufacturer shall apply.
