As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account
– persons (including children) whose
• physical, sensory or mental capabilities; or
• lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
NOTE 102 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;

Transmission of a signal between the actuating member or sensing unit and the switch may be connected
by optical, acoustic, thermal, electrical or other relevant connection and may include remote controlled
units.
This part of IEC 61058 applies to switches for appliances provided with additional control functions
governed by the switch provided with electronic circuits and devices that are necessary for the intended
and/or correct operation of the switch.
This part of IEC 61058 applies to circuitry when evaluated with a switch and necessary for the switching

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.
1.1.1 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.
1.1.2 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.

7-4.1-1.1 Scope
This part of IEC 60947 specifies requirements for PCB terminal blocks primarily intended for industrial or similar use.
Mounting and fixing on the printed circuit board is made by soldering, press-in or equivalent methods to provide electrical and mechanical connection between copper conductors and the printed circuit board.
This standard applies to PCB terminal blocks intended to connect copper conductors, with or without special preparation, having a cross-section between 0,05 mm2 and 300 mm2 (AWG 30/600 kcmil),
intended to be used in circuits of a rated voltage not exceeding 1 000 V a.c. up to 1 000 Hz or 1 500 V d.c.
NOTE 1 Large cross section terminal blocks are dedicated to specific design of high current PCBs. The range up to 300 mm2 is kept to cover any possible application. Examples of high current PCBs and PCB
terminal blocks are shown in Annex C.
NOTE 2 AWG is the abbreviation of “American Wire Gage” (Gage (US) = Gauge (UK))
kcmil = 1000 cmil;
1 cmil = 1 circular mil = surface of a circle having a diameter of 1 mil
1 mil = 1/1000 inch
This standard may be used as a guide for special types of PCB terminal blocks with components, such as disconnect units, integrated cartridge fuse-links and the like.
If applicable, in this standard the term “clamping unit” is used instead of “terminal”. This is taken into account in case of references to IEC 60947-1.
