CSA E60730-2-8:25
1.1 Scope
Replacement:
This part of IEC 60730 applies to electrically operated water valves for use in, on or in
association with equipment for household and similar use, including heating, air-conditioning
and similar applications. The equipment can use electricity, gas, oil, solid fuel, solar thermal
energy, etc., or a combination thereof.
NOTE 1 Throughout this document, the word "equipment" means "appliances and equipment."
This document is applicable to electrically operated water valves for building automation within
the scope of ISO 16484.
This document also applies to automatic electrically operated water valves for equipment that
can be used by the public, such as equipment intended to be used in shops, offices, hospitals,
farms and commercial and industrial applications.
EXAMPLE 1: Electrically operated water valves for commercial catering, heating and air-conditioning equipment.
This document does not apply to electrically operated water valves intended exclusively for
industrial process applications unless explicitly mentioned in the relevant equipment standard.
This document applies to electrically operated water valves powered by primary or secondary
batteries, requirements for which are contained within the standard, including Annex V.
This document does not cover the prevention of contamination of drinking water as a result of
contact with materials.
1.1.1 This document applies to the inherent safety, to the operating values, operating times
and operating sequences where such are associated with equipment safety, and to the testing
of automatic electrical control devices used in, on or in association with, household and similar
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 is also applicable to electrically operated water valves for appliances within the
scope of the IEC 60335 series of standards.
This document does not 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;
– electrically operated water valves designed exclusively for industrial applications.
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".
1.1.2 This document applies to electrically operated water valves, 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.
1.1.3 This document also applies to actuators and to valve bodies which are designed to be
fitted to each other.
1.1.4 This document applies to individual valves, valves utilized as part of a system and valves
mechanically integral with multi-functional controls having non-electrical outputs.
NOTE Attention is drawn to the fact that, in many countries, additional test requirements and by-laws have been
established by the water authorities or companies.
1.1.5 This document applies to AC or DC powered electrically operated water valves with a
rated voltage not exceeding 690 V AC or 600 V DC.
1.1.6 This document does not take into account the response value of an automatic action
of a valve, if such a response value is dependent upon the method of mounting the valve 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 shall apply.
1.1.7 This document applies also to electrically operated water valves incorporating
electronic devices, requirements for which are contained in Annex H.
1.1.8 This document applies also to electrically operated water valves using NTC or PTC
thermistors, requirements for which are contained in Annex J.
1.1.9 This document applies to the electrical and functional safety of electrically operated
water valves capable of receiving and responding to communications signals, including signals
for power billing rate and demand response.
The signals can be transmitted to or received from external units being part of the valve (wired),
or to and from external units which are not part of the valve (wireless) under test.
1.1.10 This document does not 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.
