This clause of Part 1 is replaced as follows: 1.1 Scope Replacement This part of IEC 60730 applies to automatic electrical air flow, water flow and water level sensing controls for use in, or in association with, boilers with a maximum pressure rating of 2 000 kPA (20 bar) and equipment for general household and similar use including controls for heating, air- conditioning and similar applications. NOTE Examples are water flow and water level sensing controls of the float or electrode-sensor type used in boiler applications and air flow, water flow and water level sensing controls for swimming pool pumps, water tank pumps, cooling towers, dishwashers, washing machines, air conditioning chillers and ventilation applications. This standard also applies to automatic electrical air flow, water flow and water level sensing 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. 1.1.1 Replacement This standard 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 air flow, water flow and water level sensing controls used in, or in association with, equipment. This standard is also applicable to controls for appliances within the scope of IEC 60335-1. Automatic electrical air flow, water flow and water level sensing 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. 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. This standard is not applicable to pressure-operated air flow, water flow and water level sensing controls, requirements for which are contained in IEC 60730-2-61). This standard does not apply to air flow, water flow and water level sensing controls designed exclusively for industrial applications unless explicitly mentioned in the relevant equipment standard NOTE Throughout this standard, the word "equipment" means "appliance and equipment". 1.1.2 Addition This standard applies to automatic electrical controls, mechanically or electrically operated, responsive to or controlling air flow, water flow and water level. 1.1.3 Not applicable NOTE Requirements for manual switches not forming part of an automatic control are contained in IEC 60669 and IEC 61058-1. 1.1.5 Replacement This standard applies to a.c. or d.c. automatic electrical air flow, water flow and water level sensing controls with a rated voltage not exceeding 690 V a.c. or 600 V d.c. 1.1.6 Replacement This standard 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. 1.1.7 Replacement 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 and PTC thermistors, requirements for which are contained in Annex J.
