EXAMPLE 1 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. - for building automation within the scope of ISO 16484 series and IEC 63044 series (HBES/BACS); EXAMPLE 2 Independently mounted air flow, water flow and water level sensing controls in smart grid systems and controls for building automation systems within the scope of ISO 16484-2. - for equipment that is used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications; EXAMPLE 3 Controls for commercial boilers, heating and air-conditioning equipment. - that are smart enabled controls; EXAMPLE 4 Smart grid control, remote interfaces/control of energy-consuming equipment including computer or smart phone. - that are AC or DC powered controls with a rated voltage not exceeding 690 V AC or 600 V DC; - used in, on, or in association with equipment that use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof; - utilized as part of a control system or controls which are mechanically integral with multifunctional controls having non-electrical outputs; - using NTC or PTC thermistors and to discrete thermistors, requirements for which are contained in Annex J; - that are mechanically or electrically operated, responsive to or controlling air flow, water flow and water level; - as well as manual controls when such are electrically and/or mechanically integral with automatic controls. NOTE 2 Requirements for manually actuated mechanical switches not forming part of an automatic control are contained in IEC 61058-1-1. This document applies to - the inherent safety of automatic electrical air flow, water flow and water level sensing controls, and - functional safety of automatic air flow, water flow and water level sensing electrical controls and safety related systems, - controls where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system, - the operating values, operating times, and operating sequences where such are associated with equipment safety. This document specifies the requirements for construction, operation and testing of automatic electrical air flow, water flow and water level sensing controls used in, on, or in association with an equipment. This document 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 applies. This document does not - apply to air flow, water flow and water level sensing controls intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard. However, this document can be applied to evaluate air flow, water flow and water level sensing controls intended specifically for industrial applications in cases where no relevant safety standard exists; - address the integrity of the output signal to the network devices, such as interoperability with other devices unless it has been evaluated as part of the control system; - apply to pressure sensing controls, the requirements for which are contained in IEC 60730-2-6. This fourth edition cancels and replaces the third edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) adoption to IEC 60730-1:2022 with all of its significant changes to IEC 60730-1:2013, IEC 60730-1:2013/AMD1:2015 and IEC 60730-1:2013/AMD2:2020.
