Annex II

Annex IV to Directive 2014/32/EU is amended as follows: (1) the title is replaced by the following: GAS METERS AND CONVERSION DEVICES (MI-002); (2) the first paragraph is replaced by the following: The relevant requirements set out in Annex I, the specific requirements set out in this Annex and the conformity assessment procedures listed in this Annex apply to gas meters and conversion devices defined in this Annex, intended for residential, commercial and light industrial use.; (3) in the part DEFINITIONS, the table is amended as follows: (a) in the first row, the second column is replaced by the following: An instrument designed to measure and to ensure the memorisation and display of the quantity of fuel gas (volume or mass) that has passed through that instrument and, if applicable, the quantity of its energy.; (b) in the second row, the first column is replaced by the following: Volume conversion device; (c) the following rows are added: Gas calorific value determining deviceAn instrument connected to or integrated into the energy conversion device for determining the calorific value of gas that has passed through that instrument. Energy conversion deviceA device that converts the quantity measured into energy using the mass or the volume at base conditions, and the superior/gross calorific value. Superior/gross calorific valueThe amount of heat that would be released by the complete combustion with oxygen of a specified quantity of gas, in such a way that the pressure, p1, at which the reaction takes place remains constant, and all the products of combustion are returned to the same specified temperature, t1, equal to that of the reactants, all of those products being in the gaseous state, except for water, which is condensed to the liquid state at t1. (4) Part I is amended as follows: (a) point 1.1 is replaced by the following: 1.1. The flowrate range of the gas shall fulfil at least the following conditions: ClassQmax/QminQmax/QtQr/Qmax 1,5≥ 150≥ 101,2 1,0≥ 10≥ 51,2 If a gas meter has multiple gas application-dependent flowrate ranges, such flowrate ranges shall be inscribed on the meter, accompanied by a clear description of the gas application.; (b) in point 3.1.1, the introductory sentence is replaced by the following: The effect of an electromagnetic disturbance on a gas meter, conversion device or gas calorific value determining device shall be such that:; (c) in point 6, the following paragraph is added: The quantity of energy shall be displayed in joules or in watt-hours or their decimal multiples.; (5) Part II is amended as follows: (a) the title is replaced by the following: SPECIFIC REQUIREMENTS CONVERSION DEVICES; (b) the first and second paragraphs are replaced by the following: A conversion device constitutes a sub-assembly when it is together with a measuring instrument with which it is compatible. For a conversion device, the essential requirements for a gas meter shall apply, if applicable. In addition, the requirements set out in points 7 to 9 shall apply.; (c) point 8 is replaced by the following: MPE for volume conversion devices 0,5 % at ambient temperature 20 oC ± 3 oC, ambient humidity 60 % ± 15 %, nominal values for power supply, 0,7 % for temperature conversion devices at rated operating conditions, 1 % for other conversion devices at rated operating conditions. Note: The errors of the gas meter and, if applicable, of the gas calorific value determining device are not taken into account. The conversion device shall not exploit the MPEs or systematically favour any party.; (d) the following point is inserted: 8a. MPE for energy conversion devices The MPE of the conversion calculation of energy is equal to 0,05 %.; (6) the following Part IIa is inserted: PART IIa SPECIFIC REQUIREMENTS GAS CALORIFIC VALUE DETERMINING DEVICES A gas calorific value determining device sends, locally or remotely, signals to the energy conversion device. For a gas calorific value determining device, the essential requirements for a gas meter shall apply, if applicable. In addition, the requirements set out in points 9a to 9f shall apply. 9a. Base conditions for converted quantities The manufacturer shall specify the following: the range for gas chemical composition, the base conditions for calorific value and converted quantities. 9b. MPE Class0,51,0 MPE0,5 %1,0 % The gas calorific value determining device shall not exploit the MPEs or systematically favour any party. 9c. Permissible effect of disturbances The critical change value is the greater of the two following values: one fifth of the magnitude of the MPE for the calorific value, two scale intervals of the gas calorific value determining device. 9d. Durability After an appropriate durability test, taking into account the period of time estimated by the manufacturer, has been performed, the following criteria shall be satisfied: the variation of the measurement result after the durability test when compared with the initial measurement result shall not exceed half of the magnitude of the MPE, and the error of indication after the durability test shall not exceed the MPE. 9e. Suitability A gas calorific value determining device shall be capable of detecting when it is operating outside the operating ranges stated by the manufacturer and shall register the following for measurement accuracy: (a) that the gas calorific value is not relevant; and (b) that the gas calorific value determining device operates outside the operating range. 9f. Units Calorific value shall be displayed in joules and/or watt-hours, or their decimal multiples, per unit of mass or volume at base conditions..
