UL Standard for Safety Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Electrically Operated Water Valves, Including Mechanical Requirements
|Publication Date:||3 February 2017|
In general, this part of IEC 60730 applies to automatic ELECTRICAL CONTROLS for use in, on, or in association with equipment for household and similar use. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof.
NOTE 1 Throughout this standard the word "equipment" means "appliance and equipment."
EXAMPLE 1 CONTROLS for appliances within the scope of IEC 60335.
This International Standard is applicable to CONTROLS for building automation within the scope of ISO 16484-2.
This standard also applies to automatic ELECTRICAL 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.
EXAMPLE 2 CONTROLS for commercial catering, heating and air-conditioning equipment.
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.
EXAMPLE 3 Independently mounted water valves, CONTROLS in smart grid systems and CONTROLS for building automation systems within the scope of ISO 16484 2.
This standard is also applicable to relays when used as CONTROLS for IEC 60335 appliances. Additional requirements for the safety and OPERATING VALUES of relays when used as CONTROLS for IEC 60335 appliances are contained in Annex U.
NOTE 2 These requirements are referred to in the scope of IEC 61810-1.
NOTE 3 This standard is intended to be used for the testing of any stand-alone relay which is intended to be used as a control of an appliance according to IEC 60335-1. It is not intended to be used for any other stand-alone relay, or to replace the IEC 61810 series of standards.
This standard does not apply to automatic ELECTRICAL CONTROLS intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard.
This standard applies to controls powered by primary or secondary batteries, requirements for which are contained within the standard, including Annex V.
This part 2-8 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 may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof.
DV D2 Modification of 1.1 of the part 2 by adding the following:
These requirements do not cover VALVES for marine use
This part 2-8 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 part 2-8 contains requirements for electrical features of water valves and requirements for mechanical features of valves that affect their intended operation.
This part 2-8 is also applicable to electrically operated water valves for appliances within the scope of IEC 60335.
Electrically operated valves for equipment not intended for normal household use but which may nevertheless 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 part 2-8.
This part 2-8 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 part 2-8, 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".
1.1.2DV DE Modification of 1.1.2 of the part 2:
In the third paragraph, replace the word "designed" with "intended".
This part 2-8 also applies to actuators and to valve bodies which are designed to be fitted to each other.
This part 2-8 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.
