Overview
EN 60335-2-51:2003/A2:2012 (CENELEC) is the European amendment to the household-appliance safety standard that sets particular requirements for stationary circulation pumps used in heating and service water installations. It implements IEC 60335-2-51:2002/A2:2011 into the EN framework and specifies safety boundaries for electric pumps intended for household and similar purposes. The standard applies to pumps with rated voltages up to 250 V for single-phase appliances and 480 V for other appliances.
Key topics and requirements
This amendment focuses on the safety aspects specific to stationary circulation pumps. Core technical topics typically addressed include:
- Scope and rated voltage limits for household and similar applications (heating systems and service water systems).
- Electrical safety: requirements for insulation, earthing, and protection against electric shock.
- Motor and thermal protection: measures to prevent overheating and motor damage in normal and fault conditions.
- Mechanical integrity: construction and stability to avoid hazards from moving parts and vibration.
- Sealing and environmental considerations: safe operation in wet or humid conditions typical of heating and water systems.
- Marking, instructions and documentation: required product identification, safe-use instructions and installation guidance for manufacturers and installers.
- Conformity and testing: reference to tests and procedures used to verify compliance with the particular requirements.
(Note: EN 60335-2-51 is a "Part 2" particular standard and works together with the general appliance safety requirements of the IEC/EN 60335 series.)
Practical applications and users
Who uses EN 60335-2-51:
- Pump manufacturers designing stationary circulation pumps for domestic central heating and service water distribution.
- Product safety and compliance engineers preparing technical files for CE marking and national approvals.
- Testing and certification laboratories performing safety tests and conformity assessments.
- HVAC designers, installers and facility managers specifying compliant pumps for residential and light-commercial heating systems.
- Regulatory bodies and market surveillance enforcing electrical safety and product standards.
Practical benefits:
- Ensures safe, reliable operation of circulation pumps in heating and domestic water systems.
- Supports regulatory compliance and market acceptance across CENELEC member countries.
- Reduces risk of electrical shock, fire, overheating and mechanical failure in installed systems.
