EXAMPLE 1 Electrically operated water valves for appliances within the scope of IEC 60335. • for building automation within the scope of ISO 16484 series and IEC 63044 series (HBES/BACS); EXAMPLE 2 Independently mounted water valves, 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 Electrically operated water valves for commercial catering, heating and air-conditioning equipment. • that are smart enabled electrically operated water valves; EXAMPLE 4 Smart grid control, remote interfaces and controls of energy-consuming equipment including computer or smart phone. • that are AC or DC powered electrically operated water valves with a rated voltage not exceeding 690 V AC or 600 V DC; • used in, on, or in association with equipment that uses 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 of Part 1; • responsive to or controlling such characteristics as temperature, pressure, passage of time, humidity, light, electrostatic effects, flow, or liquid level, current, voltage, acceleration, or combinations thereof; • in which actuators and valve bodies are designed to be fitted to each other. • as well as manual controls when such are electrically 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 electrically operated water valves, and - functional safety of electrically operated water valves 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 electrically operated water valves used in, on, or in association with an equipment. This document contains requirements for electrical features of water valves and requirements for mechanical features of valves that affect their intended operation. This document does not • apply to electrically operated water valves 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 automatic electrical controls intended specifically for industrial applications in cases where no relevant safety standard exists. • apply to - electrically operated water valves of nominal connection size above DN 50; - electrically operated water valves for admissible nominal pressure rating above 1,6 MPa; - food dispensers; - detergent dispensers; - steam valves; • take into account the response value of an automatic action of a electrically operated water valve, 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 protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer will apply. • 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. • cover the prevention of contamination of drinking water as a result of contact with materials. Throughout this document, where it can be used unambiguously, the term: - "valve" is used to denote an electrically operated water valve (including actuator and valve body assembly); - "actuator" means "electrically operated mechanism or prime mover"; - "valve body" means "valve body assembly"; - "equipment" includes "appliance" and "control system". This edition includes the following significant technical changes with respect to the previous edition: a) adoption of 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. This part 2-8 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the sixth edition of that standard (2022). Consideration may be given to future editions of, or amendments to, IEC 60730‑1.
