The objective of this Standard is to identically adopt IEC 60335-2-51 Ed 4 and publish as AS\/NZS
60335.2.51:2020 to supersede AS\/NZS 60335.2.51:2012 three years from the date of publication. <\/p>\n
Scope<\/b><\/p>\n
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
\u2013 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;
\u2013 children playing with the appliance.
NOTE 102 Attention is drawn to the fact that
\u2013 for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
\u2013 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
\u2013 pumps for circulating liquids other than water;
\u2013 pumps, other than circulation pumps (IEC 60335-2-41);
\u2013 circulation pumps intended exclusively for industrial purposes;
\u2013 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).<\/p>\n","protected":false},"excerpt":{"rendered":"
