ANNEX

PE-CONS No/YY - 2024/0311(COD)

DIRECTIVE (EU) 2025/... OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of …

amending Directive 2014/32/EU as regards electric vehicle supply equipment, compressed gas dispensers, and electricity, gas and thermal energy meters

(Text with EEA relevance)

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty on the Functioning of the European Union, and in particular Article 114 thereof,

Having regard to the proposal from the European Commission,

After transmission of the draft legislative act to the national Parliaments,

Having regard to the opinion of the European Economic and Social Committee,

Acting in accordance with the ordinary legislative procedure,

Whereas:

(1) One of the objectives of Directive 2014/32/EU of the European Parliament and of the Council on measuring instruments is to guarantee the proper functioning of the internal market. Pursuant to Article 6 of Directive 2014/32/EU, measuring instruments falling within the scope of that Directive are to meet the essential requirements set out in Annex I and in the relevant instrument-specific Annexes.

(2) The scope and the associated essential requirements covered by Directive 2014/32/EU were ▌ established by Directive 2004/22/EC, of which Directive 2014/32/EU is a recast. Technical requirements have remained unchanged for more than 20 years. In the meantime, new measuring instruments have appeared on the market that are not covered by Directive 2014/32/EU. That is notably the case for electric vehicle supply equipment and compressed gas dispensers, which are important for the successful rollout of clean mobility. Moreover, Directive 2014/32/EU does not cover requirements for thermal energy meters for cooling applications. In addition, as far as electricity and gas meters are concerned, Directive 2014/32/EU is neither adapted to the use of direct current, hydrogen and other gases that can be used as alternatives to more traditional gases, nor enables to take full advantage of smart metering which plays an important role in achieving the Union climate objectives. Therefore, it is appropriate to amend in a targeted way the scope of Directive 2014/32/EU and the essential requirements set out in the Annexes to that Directive in order to take into account technological progress. The placing on the market of measuring instruments should be further addressed in a systematic and comprehensive way through a general revision of Directive 2014/32/EU, including Annex I and instrument specific annexes, such as water meters, to adapt the current EU framework to the technological developments.

(3) Annexes I, IV, V and VI to Directive 2014/32/EU are no longer technology neutral as they do not provide essential requirements corresponding to new technologies, which provide improved protection to consumers, and should thus be amended.

(4) Annex I to Directive 2014/32/EU should be amended in order to take into account the roll out of smart gas and electricity meters and the new measuring instruments covered by the new instrument-specific Annexes.

(5) Annex IV to Directive 2014/32/EU should be amended to take into account the growing use of hydrogen and other fuel gases that can be used as alternatives to more traditional fuel gases and the roll-out of smart gas meters.

(6) Annex V to Directive 2014/32/EU should be amended to take account of the rollout of smart electricity meters and to fit with the applications using direct current.

(7) A new Annex Va to Directive 2014/32/EU should be inserted in order to address the need for harmonised essential requirements with regard to measuring systems for electric vehicle supply equipment, irrespective of their intended application, while ensuring that no retrofitting obligations are imposed on existing charging stations.

(8) Annex VI to Directive 2014/32/EU should be amended to include thermal energy meters for cooling applications in order to avoid additional certification of such products at national level.

(9) The increased use of compressed gases, such as hydrogen and natural gas, requires the insertion of a new Annex VIIa to Directive 2014/32/EU on measuring systems for compressed gas dispensers, while ensuring that no retrofitting obligations are imposed on existing compressed gas dispensers.

(10) Since the objective of this Directive, namely to ensure that measuring instruments on the market fulfil the requirements providing for a high level of protection of the public interests covered by this Directive while guaranteeing the functioning of the internal market, cannot be sufficiently achieved by the Member States but can rather, by reason of its scale and effects, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union. In accordance with the principle of proportionality, as set out in that Article, this Directive does not go beyond what is necessary in order to achieve that objective.

(11) In order to enable economic operators to supply stock of measuring instruments that are in conformity with Directive 2014/32/EU, it is necessary to provide for reasonable transitional arrangements that allow the making available on the market and putting into use of measuring instruments that have already been placed on the market in accordance with Directive 2014/32/EU before the date of application of the national measures transposing this Directive. Furthermore, specific transitional arrangements should be put in place to allow economic operators to prepare for the application of the harmonised requirements regarding electric vehicle supply equipment and compressed gas dispensers.

(11a) In order to avoid any delay in the rollout of measuring instruments after the date of application of this amending Directive, it is important that, by the date of application of this amending Directive, a sufficient number of conformity assessment bodies is notified in accordance with the new requirements and is entitled to carry out conformity assessments. For the same reason such notified bodies should be able to issue certificates for the measuring instruments defined in the instrument-specific Annexes II, III and V to this amending Directive by the date of application of this amending Directive.

(12) Moreover, in order to provide sufficient time for manufacturers to adapt their products to the essential requirements set out in the Annexes to this Directive, it is also necessary to provide for reasonable transitional arrangements that allow the making available on the market and putting into use of measuring instruments that have been placed on the market in accordance with national certificates or for which a certificate was issued under Directive 2014/32/EU before the date of application of the national measures transposing this Directive, and that will fall in the scope of Directive 2014/32/EU as of the date of entry into force of this Directive.

(13) Directive 2014/32/EU should therefore be amended accordingly,

HAVE ADOPTED THIS DIRECTIVE:

‘ANNEX VIIa

MEASURING SYSTEMS FOR COMPRESSED GAS DISPENSERS (MI-012)

The relevant requirements of Annex I, the specific requirements of this Annex and the conformity assessment procedures listed in this Annex apply to measuring systems intended for the continuous and dynamic measurement of quantities (mass and, if applicable, energy) of compressed gas.

▌Such measuring systems shall not be considered as utility measuring instruments as defined in Annex I.

DEFINITIONS

Meter

An instrument designed to measure continuously and to ensure the memorisation and display of the quantity of gas, at metering conditions, flowing through the measurement transducer in a closed, fully charged conduit.

Calculator

A part of a meter that receives the output signals from the measurement transducers and possibly, from associated measuring instruments and displays the measurement results.

Associated measuring instrument

An instrument connected to the calculator for measuring certain quantities, which are characteristic of the gas, with a view to make a correction and/or conversion.

Conversion device

A part of the calculator, which by taking into account the characteristics of the gas, automatically converts the mass of the gas into the amount of energy delivered or received.

Measuring system

A system that comprises, in addition to the meter itself, a transfer point, gas piping and all devices required to ensure correct measurement or intended to facilitate the measuring operations.

Compressed gas (‘CG’) dispenser

A measuring system intended for the fuelling of motor vehicles, rail engines, boats, vessels and aircraft with compressed gaseous fuel.

Transfer point

Physical location at which the gas is defined as being delivered or received.

Self-service arrangement

An arrangement that allows customers to use a measuring system for the purpose of obtaining gas for their own use.

Self-service device

A specific device that is part of a self-service arrangement and that allows one or more measuring systems to perform in that self-service arrangement.

Minimum measured quantity (‘MMQ’)

The smallest quantity of gas for which the measurement is metrologically acceptable for the measuring system.

Direct indication

The indication of mass and, if applicable, energy, corresponding to the measure and that the meter is physically capable of measuring. Note: The direct indication may be converted into another quantity using a conversion device.

Interruptible

A measuring system is considered as interruptible when the gas flow can be stopped easily and rapidly.

Non-interruptible

A measuring system is considered as non-interruptible when the gas flow cannot be stopped easily and rapidly.

Flowrate range

The range between the minimum flowrate (Qmin) and maximum flowrate (Qmax).

SPECIFIC REQUIREMENTS

1. Rated operating conditions

The manufacturer shall specify the rated operating conditions for the instrument, in particular:

1.1. The flowrate range

The flowrate range is subject to the following conditions:

(a) the flowrate range of a measuring system shall be within the flowrate range of each of its elements, in particular the meter; and

(b) ▌ the ratio between the ▌ maximum and minimum flow rate shall be no less than 10.

1.2. The properties of the gas to be measured by the instrument by specifying the name, the type or the following relevant characteristics of that gas such as:

(a) temperature range;

(b) pressure range;

(c) the calorific value of the gas;

(d) the nature and characteristics of the gas to be measured.

1.3. The nominal value of the AC voltage supply and/or limits of the DC voltage supply.

2. Accuracy classification and MPEs

2.1. The MPE on the indication of measured or converted amounts transferred at the transfer point is set out in Table 1.

Table 1

Type of compressed gas measuring systems

Accuracy Class (MPE [% of measured value])

Compressed hydrogen measuring systems

2,0

1,5

The MPE on the MMQ equals twice the value stated in Table 1.

2.2. The MMQ of a measuring system shall have the form 1 × 10n, 2 × 10n, or 5 × 10n authorised units of mass or energy, where n is a positive or negative whole number, or zero.

The MMQ shall satisfy the conditions of use of the measuring system; except in exceptional cases, the measuring system shall not be used for measuring quantities less than that MMQ.

2.3. The measuring system shall not exploit the MPEs or systematically favour any party.

3. Maximum permissible effect of disturbances

3.1. The effect of an electromagnetic disturbance on a measuring system shall be one of the following:

(a) the change in the measurement result is not greater than the critical change value pursuant to point 3.2;

(b) the indication of the measurement result shows a momentary variation that cannot be interpreted, memorised or transmitted as a measurement result; furthermore, in the case of an interruptible system, that can also mean the impossibility to perform any measurement; or

(c) the change in the measurement result is greater than the critical change value pursuant to point 3.2, in which case the measuring system shall permit the retrieval of the measurement result just before the critical change value occurred and cut off the flow.

3.2. The critical change value is the greater of the following values:

– 10% of the MPE;

– 3% of the MMQ ▌ ; in the case of a failure of the main power source, the critical change value shall be increased by 5 % of the MMQ.
