1 Scope and normative references
This clause of Part 1 is replaced as follows:
1.1 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. EN 60730‑2‑1 is not applicable to electrical water level sensing controls of the float or electrode-sensor
type.
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.
1.1.1 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, household and similar equipment.
This standard is also applicable to controls for appliances within the scope of IEC 60335‑1 and IEC 60364‑7‑702.
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.
Throughout this standard, the word "equipment" means "appliance and equipment".
1.1.2 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 This standard contains requirements for electrical features of air flow, water flow
and water level sensing controls and requirements for mechanical features that may
affect their intended operation and electrical safety.
1.1.4 This standard applies to manual controls when such are electrically and/or mechanically
integral with air flow, water flow and water level sensing controls.
Requirements for manual switches not forming part of an automatic control are contained
in IEC 60669 and IEC 61058‑1.
1.1.5 In general, these air flow, water flow and water level sensing controls are integrated
or incorporated with the equipment or are intended to be integrated or incorporated
in or on the equipment. This standard also covers controls when they are independently
mounted or of inline cord construction.
