36、es to electrically operated water valves for use in, on or in association with equipment for household and similar use that may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof, including heating, air-conditioning and similar applications. EN 60730-2-1 does

37、not apply to water valves. 1.1.1 This part 2-8 contains requirements for electrical features of water valves and requirements for mechanical features of valves that affect their intended operation. 1.1.2 This part 2-8 applies to the inherent safety, to the operating values, operating sequences where

38、 such are associated with equipment protection, and to the testing of automatic electrical controls used in, on or in association with household and similar equipment. Electrically operated valves for equipment not intended for normal household use but which may nevertheless be used by the public, s

39、uch 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 designed exclusively for industrial applications. This part 2-8 does not apply to: electrically operated

40、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.
