Full Description

This clause of Part 1 is replaced by the following.

This Part of IEC 60335 deals with the safety of electric clocks having a rated voltage not more than 250 V including direct current (DC) supplied appliances and battery-operated appliances.

Examples of appliances that are within the scope of this standard are
– alarm clocks;
– spring-driven clocks with an electrically operated winding mechanism;
– clocks incorporating driving means other than motors.

NOTE See Figure 101 and Figure 102 for examples of clocks that are and are not covered by this standard.

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.
Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can be necessary;
– in many countries additional requirements are specified by the national health authorities,
the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to
– appliances intended exclusively for industrial purposes;
– appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– clocks having other functions, whether or not in combination with time indication, such as master control clocks and timers for cooking ranges, washing machines and similar appliances;
– clocks for "clocking-in" purposes;
– clocks incorporating electronic circuits only (IEC 60065, IEC 62368-1);
– watches.
