Automatic electrical controls for household and similar use – Part 2-17: Particular requirements for electrically operated gas valves, including mechanical requirements
|Publication Date:||1 November 2007|
|ICS Code (Automatic controls for household use):||97.120|
This clause of part 1 is replaced as follows:
This part 2 of IEC 60730 applies to electrically operated gas valves for use in, on or in association with, equipment for household and similar use that use electricity, in combination with fuel in the gaseous state such as manufactured gas, natural gas or liquefied petroleum gas intended to be used for gas burning equipment.
Additional considerations may be necessary for gas with corrosive properties.
This part 2 also applies to electrically operated gas valves using NTC or PTC thermistors, requirements for which are contained in annex J.
This part 2 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 electrically operated gas valves used in, or in association with, household or similar equipment.
This part 2 is also applicable to controls for appliances within the scope of IEC 60335-1.
Throughout this part 2 the word "equipment" means "appliance and equipment".
This part 2 does not apply to electrically operated gas valves designed exclusively for industrial applications.
Electrically operated gas valves 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 part 2.
This part 2 identifies a number of mechanical features as "under consideration". Until these mechanical requirements are incorporated in this part 2, each country using this part 2 will have to quantify these requirements.
Compliance of an electrically operated gas valve with this part 2 does not imply that the valve is acceptable without further tests for these mechanical features.
This part 2 applies to manual controls when such are electrically and/or mechanically integral with electrically operated gas valves.
Requirements for manual switches not forming part of an electrically operated gas valve are contained in IEC 61058-1.
This part 2 does not apply to electrically operated gas valves of nominal connection size above DN 150.
This part 2 applies to electrically operated gas valves for maximum working pressures up to 400 kPa (4 bar).
Hereinafter, the term "valve" is used to denote an electrically operated gas valve (including prime mover and valve body).
An electric actuator that is submitted to the testing laboratory in combination with a gas valve will be evaluated under this part 2. A separate electric actuator is evaluated under IEC 60730-2-14, which provides particular requirements for electric actuators.
This part 2 also applies to valves utilized as part of a system, or valves mechanically integral with multifunctional controls.
This part 2 does not apply to valves energized by thermoelectric energy generated in a thermocouple or thermopile inserted in a gas flame.
Is not applicable.
