  • SCOPE

    1 Scope and normative references

    This clause of part 1 is applicable except as follows:

    1.1 Replacement:

    This part of IEC 60730 applies to automatic electrical water level operating controls of the float type for use in, on or in association with equipment for general household and similar use.

    Examples are water level controls for swimming pool pumps, water tank pumps, cooling towers, dishwashers, and washing machines.

    1.1.1 This part 2 applies to the inherent safety, to the operating values, operating sequences where such are associated with equipment protection, and to the testing of automatic electrical water level operating controls used in, on or in association with household and similar equipment.

    This part 2 is also applicable to controls for appliances within the scope of IEC 60335, IEC 60378 and IEC 60364-7-702.

    Automatic electrical water level operating 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 part 2.

    This part 2 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.

    This part 2 is not applicable to pressure operated water level sensing controls for boiler applications, requirements for which are contained in IEC 60730-2-15.

    This part 2 does not apply to water level operating controls designed exclusively for industrial applications.

    Throughout this part 2, the word "equipment" means "appliance and equipment."

    1.1.2 This part 2 applies to automatic electrical controls, mechanically operated, responsive to or controlling a water level.

    1.1.3 This part 2 contains requirements for electrical features of water level operating controls and requirements for mechanical features that may affect their electrical safety.

    1.1.4 This part 2 applies to manual controls when such are electrically and/or mechanically integral with water level operating controls.

    1.1.5 In general, these water level operating controls are integrated or incorporated with the equipment or are intended to be integrated or incorporated in or on the equipment. This part 2 also covers these controls when they are independently mounted or of in-line cord construction.

    1.2 Replacement:

    This part 2 applies to controls with a rated voltage not exceeding 660 V and a rated current not exceeding 63 A.

    1.3 Replacement:

    This part 2 takes into account the response value of an automatic action of a control where such a response value is dependent upon the method of mounting the control. 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 Replacement:

    This part 2 applies also to controls incorporating electronic devices, requirements for which are contained in annex h.
