1. Scope

This standard applies to automatic electrical controls for electrical household appliances within the scope of IEC Publication 33 5-1 and its relevant Part 2s. Where for a specific control, a Part 2 of Publication 730-1 has been published, it supersedes the requirements for the specific controls contained in this Part 2.

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 automatic electrical control devices used in, or in association with, household or similar equipment.

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

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 or acceleration.

This standard applies to starting relays, which are a specific type of automatic electrical control, designed 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 which are el ectrically and/or mechanically integral with automatic controls.

Requirements for manual switches not forming part of an automatic control are contained in IEC Publication 328.

This standard applies to controls with a rated voltage not exceeding 660 V and with a rated current not exceeding 63 A.

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 pr otection 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.This standard is not applicable to controls used in central he ating, air conditioning and similar applications.
