Household and similar electrical appliances - Safety - Part 2-51: Particular requirements for stationary circulation pumps for heating and service water installations

Scope

IEC 60335-2-51:2002+A1:2008+A2:2011 deals with the safety of electric stationary circulation pumps intended for use in heating systems or in service water systems, having a rated power input not exceeding 300 W, their rated voltage being not more than 250 V for single-phase and 480 V for other appliances. Hydraulic and electric parts of the pump may be in the same enclosure, so that the water serves as a coolant, or they maybe seperate. This standard does not apply to:<br /> - pumps for circulating liquids other than water;<br /> - pumps, other than circulation pumps (IEC 60335-2-41);<br /> - circulation pumps intended exclusively for industrial purposes;<br /> - circulation pumps intended for locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapor, or gas). <br /><br />This publication is to be read in conjunction with <a href=''http://webstore.iec.ch/webstore/webstore.nsf/ArtNum_PK/44013''> IEC 60335-1:2010</a>.<br /><br /><b>This consolidated version consists of the third edition (2002), its amendment 1 (2008) and its amendment 2 (2011).
