  • SCOPE

    1 Scope and normative references

    This clause of part 1 is applicable as follows:

    1.1 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.

    1.1DV Modification of 1.1 of the part 2 by adding the following:

    These requirements do not cover valves for marine use.

    1.1.1 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.

    1.1.1DV Modification of 1.1.1 of the part 2:

    In the fifth paragraph, sixth dashed item, replace the word “designed” with “intended”.

    1.1.2 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”.

    1.1.3 This part 2-8 also applies to actuators and to valve bodies which are designed to be fitted to each other.

    1.1.4 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.
