M/469 - Circulators
Mandate to CEN, CENELEC and ETSI for Standardisation in the field of circulators
Mandate M/469 directs the European Standardisation Organisations CEN, CENELEC, and ETSI to develop and adopt harmonised standards in the field of circulators. The mandate aims to support regulatory frameworks and market needs by ensuring safety, performance, and interoperability criteria for circulators across the EU. The decision relates to the approval or disapproval of the mandate as noted in resolution CEN BT C77/2010. This initiative facilitates the alignment of national standards with European regulations to promote a unified market and enhance consumer protection in the circulator sector.
Purpose
The mandate M/469 requests standardisation activities related to circulators. It aims to guide the European standardisation organisations in developing or updating standards in this field to support regulatory and market needs.
Standardisation request
The mandate is addressed to the three European standardisation bodies:
- CEN (European Committee for Standardisation)
- CENELEC (European Committee for Electrotechnical Standardisation)
- ETSI (European Telecommunications Standards Institute)
These organisations are tasked with harmonising standards covering circulators, which are components likely used in technical or industrial applications.
Expected deliverables
The mandate expects the involved bodies to produce harmonised standards or technical specifications that align with the objectives of European legislation and market requirements. Such deliverables would facilitate interoperability, safety, efficiency, and market integration of circulators within the EU.
Context
Mandate M/469 was considered and (dis-)approved as documented in resolution CEN BT C77/2010. It fits within the broader EU strategy to establish common technical standards across member states to ensure the free circulation of goods and compliance with relevant directives. The specific focus on circulators reflects regulatory or market priorities identified at the time.
The mandate covers standardisation in the field of circulators, specifically focusing on products such as circulator pumps used in heating, ventilation, and air-conditioning (HVAC) systems. It aims to develop standards related to energy efficiency, performance, and safety requirements for circulators within the relevant sectors.
General Information
This European Standard specifies a test code for the vibro-acoustic characterization of glandless circulators with pump housing having a rated power input P1 ≤ 200W, intended to be used in heating installations, domestic hot water service installations and cooling systems, and is limited to glandless circulators with threaded connections of 11/2 inch. The test code comprises the test rig, the measurement method and the test conditions.
This European Standard applies to glandless circulators, which are manufactured after the date of issue of this European Standard.
The characterization principle is based on measuring the structure-borne and the fluid-borne power transmitted respectively by vibration and pressure fluctuations in the pipe connected to a glandless circulator.

This European Standard specifies general performance requirements and general requirements and procedures for testing and calculation of the energy efficiency index (EEI) for glandless circulators having a rated hydraulic output power of between 1 W and 2500 W designed for use in heating systems or cooling distribution systems.
All known hazards which are likely to occur at normal installation and operation are covered by the European Standards EN 809 and EN 60335-2-51.
As regards safety for electro-technical parts of circulators, EN 60335-2-51 applies.

Frequently Asked Questions
A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.
M/469 is a European Standardization Mandate titled "Mandate to CEN, CENELEC and ETSI for Standardisation in the field of circulators". Mandate to CEN, CENELEC and ETSI for Standardisation in the field of circulators There are 8 standards developed under this mandate.
Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.
