1.1 In general, this International 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.
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, household or similar equipment.
This standard is also applicable to controls for appliances within the scope of IEC 60335-1.
This standard is also applicable to controls for building automation systems within the scope of ISO 16484-2
NOTE 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 unless explicitly mentioned in the relevant part 2.
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.
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 by IEC 61810-1:2008, Clause 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.
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.
NOTE Starting relays are tested as voltage sensing or current sensing controls.
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.
1.2 This standard applies to controls with a rated voltage not exceeding 690 V and with a rated current not exceeding 63 A.
1.3 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.
1.4 This standard applies also to controls incorporating electronic devices, requirements for which are contained in Annex H.
This standard applies also to controls using NTC or PTC thermistors, requirements for which are contained in Annex J.
