CSA E60335-2-51:23
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric stationary circulation pumps for
household and similar purposes intended for use in heating systems or in service water
systems, their rated voltage being not more than 250 V for single-phase appliances and
480 V for other appliances.
NOTE 101 The hydraulic and electrical parts of the pump can be in the same enclosure, so that the water flows
through the motor and serves as a coolant, or they can be separated.
Appliances not intended for normal household use, but that nevertheless may be a source of
danger to the public, such as appliances intended to be used by laymen in shops, in light
industry and on farms, are within the scope of 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.
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 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.
NOTE 103 This standard does not apply to
– pumps for circulating liquids other than water;
– pumps, other than circulation pumps (IEC 60335-2-41);
– circulation pumps intended exclusively for industrial purposes;
– circulation pumps intended to be used in locations where special conditions prevail, such as the presence of a
corrosive or explosive atmosphere (dust, vapour, or gas).
This Standard applies to the safety of such equipment that is intended to be installed or used in
accordance with CSA C22.1, Canadian Electrical Code, Part I.
