Measuring instruments allow accuracy of measurement – water meters, gas meters, electricity meters, etc. - and play a more and more significant role in today's society, by raising the industry and consumers' awareness on their actual consumption and making them more environmentally responsible.
In the field of measurement, CEN develops standardization deliverables for heat, gas, and water meters, whereas the electricity sector is covered by CENELEC.
Directive
-
Measuring Instruments Directive (MID) –
2004/22/EC
In 2004, the Council and the European Parliament adopted the MID, which applies to the design, manufacturing and conformity assessment of measuring instruments. The directive covers 10 categories of measuring instruments and mainly addresses precision, reliability and security of instruments. Standards developed in compliance with the MID are recognised as 'harmonized' standards and are cited in the Official Journal of the European Union (OJEU).
Mandates
-
M/347 – Programming mandate to CEN, CENELEC and ETSI relating to measuring instruments
The mandate requested the European Standardization Organizations (ESOs) to prepare a work programme of European Standards in order to support the MID.
In the joint response to the mandate, CEN identified work to be carried out by three Technical Committees (CEN/TC 92 'Water meters'; CEN/TC 176 'Heat meters'; CEN/TC 237 'Gas meters') and which consisted in the updating by amendment or revision of already adopted European Standards to conform the essential requirements of the directive.
-
M/374 – Mandate to CEN and CENELEC for standardization in the field of measuring instruments
The mandate invited CEN and CENELEC to develop standards for measuring instruments, as described in the joint response to the programming mandate M/347.
-
M/412 – Standardization mandate to CEN and CENELEC in the field of non-automatic weighing instruments for the revision of EN 45501:1992
The mandate invites CEN and CENELEC to draw up standards for non-automatic weighing instruments (NAWI) in order to update the existing EN 45501, taking into consideration electromagnetic compatibility.
A CEN/CENELEC Joint Working Group (CEN/CENELEC JWG NAWI) has been set up to carry out the requested work.
-
M/441 – Standardization mandate to CEN, CENELEC and ETSI in the field of measuring instruments for the development of an open architecture for utility meters involving communication protocols enabling interoperability
The mandate invites the three ESOs to develop European Standards for an open architecture for utility meters involving communication protocols that enables interoperability.
More information on the work performed under the mandate is available here.
-
M/457 - Standardization mandate to CEN, CENELEC and ETSI in the field of tyre pressure gauges for motor vehicles and tyre pressure management systems (measuring instruments)
The mandate invites ESOs to create European standards for the metrological aspects of tyre pressure gauges which operate using pressure equipment to inflate the tyres of road using vehicles (cars, trucks) and which may cover the introperability of the tyre pressure gauges withthe tyre pressure management systems which monitor the pressure of the tyre of the vehicle, whereby the TPG may be steered by the TPMS.
CEN Consultant
Mr Ian Turner has been appointed as CEN consultant for measuring instruments.
