|Publication Date:||1 March 2019|
|ICS Code (Automatic controls for household use):||97.120|
|ICS Code (Electrical accessories in general):||29.120.01|
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 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 electric actuators powered by primary or secondary batteries, requirements for which are contained within the standard, including Annex V.
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 in 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.
Requirements for manual switches not integral with an electric actuator are contained in IEC 61058-1.
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.
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.
This part 2-14 applies also to electric actuators incorporating electronic devices, requirements for which are contained in Annex H.
This part 2-14 applies also to electric actuators using NTC or PTC thermistors, requirements for which are contained in Annex J.
This part 2-14 applies to the electrical and functional safety of electric actuators 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 electric actuator (wired), or to and from external units, which are not part of the electric actuator (wireless) under test.
This part 2-14 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.
