2004/22/EC - Measuring instruments
Directive 2004/22/EC, known as the Measuring Instruments Directive (MID), harmonizes the legislative framework for placing measuring instruments on the EU market. It covers a range of devices including water, gas, and electricity meters, heat meters, weighing instruments, taximeters, and exhaust gas analyzers. The directive establishes essential requirements for accuracy, reliability, and electromagnetic immunity, ensuring instruments meet high levels of performance and consumer protection. It mandates conformity assessment procedures and the affixing of the "CE" marking alongside a supplementary metrology marking to signify compliance. Member States may require legal metrological control for public interest purposes such as health, safety, taxation, and fair trading but must not create barriers to free movement of compliant instruments. The directive also provides guidelines for technical documentation, conformity assessment, and notification of designated bodies responsible for certification. Harmonized or internationally recognized standards serve as references, facilitating innovation and maintaining market access across the EU. Overall, MID streamlines market entry and usage of legally controlled measuring instruments, balancing harmonization with national regimes where justified.
Purpose
Directive 2004/22/EC, also known as the Measuring Instruments Directive (MID), establishes harmonised rules relating to the making available on the market and putting into use of measuring instruments within the European Union. Its primary aim is to ensure that measuring instruments meet specified essential requirements and performance standards to guarantee reliability, accuracy, and legal metrological control. The Directive supports the free movement of measuring instruments by preventing technical barriers and ensuring uniformity in requirements related to public interest aspects such as public health, safety, consumer protection, environmental protection, taxation, and fair trade.
The Directive replaces multiple older specific directives and introduces a coherent framework based on the New Approach principles to technical harmonisation and standards. It also sets conformity assessment procedures and marking requirements, notably the "CE" marking combined with a supplementary metrology marking.

This European Standard specifies the requirements and tests for the construction, performance, safety and production of class 1,5 diaphragm gas meters (referred to as meters). This applies to meters with co-axial single pipe, or two pipe connections, that are used to measure volumes of fuel gases, which are within the limits of test gases of the 1st, 2nd and 3rd families described in EN 437. The meters have maximum working pressures not exceeding 0,5 bar and maximum actual flow rates not exceeding 160 m3.h−1 over a minimum ambient temperature range of −10 °C to 40 °C and a gas temperature range as specified by the manufacturer with a minimum range of 40 K.
This standard applies to meters with and without built-in temperature conversion that are installed in locations with vibration and shocks of low significance (see MID Annex 1 Chapter 1.3.2 (a), class M1). It also applies to meters in:
- closed locations (indoor or outdoor with protection as specified by the manufacturer) both with condensing humidity or with non-condensing humidity;
or, if specified by the manufacturer:
- open locations (outdoor without any covering) both with condensing humidity and with non-condensing humidity;
- in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial and light industrial buildings (see MID Annex 1 Chapter 1.3.3 (a), class E1).
Unless otherwise stated, all pressures given in this document are gauge pressure.
Requirements for electronic indexes, batteries, valves incorporated in the meter and other additional functionalities are given in EN 16314.
Unless otherwise stated in a particular test, the tests are carried out on meters that include additional functionality devices intended by the manufacturer.
Clauses 1 to 9 and Annexes B and C are for design and type testing only.
NOTE The content of OIML Publication 'International Recommendation R 137' has been taken into account in the drafting of this standard.
If no specific requirements are given for test equipment, the instruments used should be traceable to a national or international reference standard and the uncertainty (2σ) should be better than 1/5 of the maximum value of the parameter to be tested. For differential results the repeatability (2σ)/resolution should be better than 1/5 of the maximum value of the parameter to be tested.

This European Standard specifies the requirements and tests for the construction, performance, safety and production of class 1,5 diaphragm gas meters (referred to as meters). This applies to meters with co-axial single pipe, or two pipe connections, that are used to measure volumes of fuel gases, which are within the limits of test gases of the 1st, 2nd and 3rd families described in EN 437. The meters have maximum working pressures not exceeding 0,5 bar and maximum actual flow rates not exceeding 160 m3.h−1 over a minimum ambient temperature range of −10 °C to 40 °C and a gas temperature range as specified by the manufacturer with a minimum range of 40 K.
This standard applies to meters with and without built-in temperature conversion that are installed in locations with vibration and shocks of low significance (see MID Annex 1 Chapter 1.3.2 (a), class M1). It also applies to meters in:
- closed locations (indoor or outdoor with protection as specified by the manufacturer) both with condensing humidity or with non-condensing humidity;
or, if specified by the manufacturer:
- open locations (outdoor without any covering) both with condensing humidity and with non-condensing humidity;
- in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial and light industrial buildings (see MID Annex 1 Chapter 1.3.3 (a), class E1).
Unless otherwise stated, all pressures given in this document are gauge pressure.
Requirements for electronic indexes, batteries, valves incorporated in the meter and other additional functionalities are given in EN 16314.
Unless otherwise stated in a particular test, the tests are carried out on meters that include additional functionality devices intended by the manufacturer.
Clauses 1 to 9 and Annexes B and C are for design and type testing only.
NOTE The content of OIML Publication 'International Recommendation R 137' has been taken into account in the drafting of this standard.
If no specific requirements are given for test equipment, the instruments used should be traceable to a national or international reference standard and the uncertainty (2σ) should be better than 1/5 of the maximum value of the parameter to be tested. For differential results the repeatability (2σ)/resolution should be better than 1/5 of the maximum value of the parameter to be tested.

This Technical Report is based on two Study Reports of CLC/SC 205A, having been worked out by their Task Force EMI [1a][1b] and provides the results and findings of these documents. It was created with the help and input from a broad range of involved stakeholders: network operators, equipment manufacturers, universities, accredited test houses and consultants.
Beside the actual standardization situation it reflects the current emission situation found in supply networks and installations and describes electromagnetic interference (EMI) cases from twelve countries; investigation and analysis of the latter show a wide range of different types of electrical devices to be considered as a source or a victim of related EMI.
This Technical Report highlights the occurrence of high levels of non-intentional emissions (NIE) in the considered frequency range, including values up to and exceeding the standardized limits for intentional signals from mains communicating systems (MCS), which also implies a high potential to cause EMI to other electrical equipment. On the other hand, several types of equipment show susceptibility to related emissions, being insufficiently immune.
The Technical Report addresses the following issues:
- a number of different types of electrical equipment are generating such emissions and/or are susceptible, to such, thus representing EMI potential, as a source or a victim of such EMI;
- the interaction of electrical equipment in a certain supply area respectively installation, with its complex and volatile impedance character, as having an additional EMI potential; that besides NIE from general electrical equipment and signals from MCS and technically being quite different from emissions;
- the fact that besides the conducted interference also radiated interference from NIE or signals from MCS, through the magnetic H-field following to related currents on the mains, is to be considered, what is of some importance also for the interference-free operation of broadcast time-signal systems or electronic circuits controlled by such;
- the ageing of electronic components in electric equipment, which causes increased emissions and EMI to other electrical equipment as a result of not showing the same EMC characteristics as before being placed on the market, therefore no longer being able to conform with EMC requirements;
- the additional aspect of differential mode operation, which should be considered for related immunity and testing specifications.
These findings confirm that EMI in this frequency range is not limited to single types of equipment like inverters or MCS; instead a more general electromagnetic compatibility (EMC) problem concerning a larger spectrum of electrical equipment is identified.
Although a case-by-case mitigation of related EMI cases might be seen as appropriate, the increasing application of technologies and systems with related EMI potential requires a more general solution, through standardization, taking a balanced viewpoint of EMC and economics into account. With regard to the actual standardization situation, a review of the actual EMC and Product standards based on the reported results seems to be advisable.
After initiating the work in CLC/SC 205A, the now ongoing work in IEC SC 77A, as well as the publication of a related Technical Report on testing electricity meters [2] by CLC/TC 13 and of the new Immunity testing standard EN 61000-4-19 [99], appear as right steps into the right direction but needing further, extended efforts.
As stated on European as well as on international EMC standardization level, the availability of compatibility levels for the considered frequency range appears as a key-requirement for future considerations on setting related emission limits and immunity requirements in various standards. A fundamental basis for the co-existence of intentional signals from MCS and NIE needs to be found.

An EU Directive is a legislative act of the European Union that sets out goals that all EU member states must achieve. However, it is up to each member state to devise their own laws on how to reach these goals through national transposition. Directives are used to harmonize laws across the EU, particularly for the functioning of the single market.
Directive 2004/22/EC covers "Measuring instruments". There are 142 standards associated with this directive.
Harmonized standards under 2004/22/EC are European standards (ENs) developed by CEN, CENELEC, or ETSI in response to a mandate from the European Commission. When these standards are cited in the Official Journal of the European Union, products manufactured in conformity with them benefit from a presumption of conformity with the essential requirements of 2004/22/EC, facilitating CE marking and free movement within the European Economic Area.
