Basic concepts
In this Regulation:
(a) the measuring instrument considers any device or system with a measuring function as specified in Section 1;
(b) a separate sub-assembly shall consider the technical equipment listed in Annexes 3 to 12 to this Regulation which may operate independently and form a measuring instrument together with other separate sub-assemblies with which it is compatible or with which it is compatible;
(c) the additional device considers a technical device which is not a separate sub-assembly, which is therefore not part of the measuring instrument and which provides certain specific functions in conjunction with the measuring instrument;
(d) the water meter shall consider a measuring instrument intended for measuring, recording and indicating the volume of water flowing through the measuring sensor under the conditions of measurement which are intended for measuring the volumes of clean cold or hot water in residential, commercial and light industry;
(e) the gas meter shall consider the gauge intended for measuring, recording and indicating the quantity (volume or mass) of the heating gas which it has produced which is intended for use in residential, commercial and light industry;
(f) an electric meter to measure active energy is considered to measure active electrical energy consumed in the electrical circuit intended for use in residential, commercial and light industry;
(g) the heat meter is a gauge which is intended for use in residential and commercial spaces and in the light industry and which is designed to measure the heat which is transmitted in the heat exchanger to a liquid called heat transfer liquid;
(h) the measurement system for continuous and dynamic measurement of quantities of liquids other than water shall consider equipment designed for continuous measurement, recording and indicating the amount of liquid flowing through the measuring converter in a closed and fully filled pipe under the conditions of measurement;
(i) the automatic weighing instrument shall consider the device which determines the weight of the product without the operator's intervention and shall proceed according to a pre-determined automatic programme which is characteristic of the measuring instrument, which shall be designed to determine the mass of the body by applying gravity to that body;
(j) the taximeter shall consider a device which works together with the signal generator and which forms a gauge with it; the device measures the duration of the journey and calculates the distance travelled on the basis of the signal received from the signal generator and calculates the fare charged on the basis of the calculated distance or duration of the journey,
(k) shall consider the measure of incarnation of equipment intended to reproduce or supply one or more values of the variable in a permanent manner during use; measurements shall be considered as embodied in this Regulation, on the one hand, tangible measuring instruments, the material measuring instruments being devices containing scale marks, the distance of which is given and, on the other hand, measuring vessels which serve to determine the determined volume of liquid (excluding pharmaceutical products) sold for immediate consumption (for example, filler glass, jug or tidal),
(l) measuring instruments for measuring dimensions include measuring instruments for measuring length, which for the purposes of this Regulation are measuring instruments used for determining the length of retractable materials (for example, textiles, belts, cables) during reeling of the measured article, measuring instruments for measuring the surface (for example, leather gauges), which are meters used for the purposes of this Regulation for determining the area of objects of irregular shapes (for example, leather), and multidimensional measuring instruments which for the purposes of this Regulation are meters used for determining the circumference dimension (length, height, width) of the smallest rectangular parallel, containing the measured object;
(m) the exhaust gas analyser shall consider the gauge used to determine the volumes of the specified components of the exhaust gas of a motor vehicle with a positive ignition engine at a certain level of humidity of the sample analysed, the components of which are carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) and hydrocarbons (HC). The hydrocarbon content must be expressed by the concentration of n-hexane (C6H14) measured using methods using close infrared absorption, the volume shares of the components of the gas must be expressed as a percentage of the volume (% v / v) for carbon monoxide, carbon dioxide and oxygen and in millionths of the volume (ppm v / v) for hydrocarbons and the exhaust gas analyser shall in addition calculate the value of the lambda coefficient from the volume shares of the components.

If the conformity assessment procedure so provides, the" CE' marking and the supplementary metrological marking shall be followed by the identification number of the notified person concerned.
(3) If the measuring instrument consists of several devices, but are not separate sub-assemblies but work together, the marking shall be placed on the main device of the measuring instrument. If the gauge is too small or sensitive to include the CE marking and the supplementary metrological marking, this marking shall be placed on the packaging, if any, and on the accompanying documents required by this Regulation. The "CE 'marking and the supplementary metrological marking shall be affixed to measuring instruments for which conformity has been established in such a way that they are easily visible, legible and unremovable. The identification number of the notified person concerned shall be indelible or affixed in such a way that it cannot be removed without damage. All markings shall be easily visible or at least easily accessible.
(4) The measuring instrument shall not bear a marking which could mislead anyone as to the meaning and shape of the "CE 'marking and the supplementary metrological marking. The measuring instrument may be affixed by any other marking provided that the visibility and legibility of the" CE' marking and the supplementary metrological marking are not thereby reduced. Infringement of this provision is punishable under specific legislation.
(5) The "CE" marking may be used only if the requirements of the specific legislation, which also provides for the measure of the meter, are fulfilled by the "CE" mark and apply to the gauge. In this case, the documents, warnings or instructions required by these specific legislation and annexed to the gauge shall contain references to those specific legislation as published in the Collection of Laws.

1.2 The solutions adopted as a result of the requirements imposed on the gauge by this Regulation shall take into account the intended use of the gauge and its foreseeable incorrect use.
2. Technical concepts
2.1 The measured value is the specified value which is the subject of the measurement.
2.2 An influencing variable is a variable which is not a measured variable but which affects the result of the measurement.
2.3 The specified working conditions are the values of the measured variable and the influencing quantities which constitute the normal working conditions of the measuring instrument.
2.4 The failure is a variable whose value lies within the limits set by a particular requirement but is outside the specified working conditions of the gauge. The influencing variable is a failure if the specified working conditions are not specified for such influencing variable.
2.5 The critical change value is that at which the change in the measurement result is considered undesirable.
2.6 Direct sales is a commercial transaction if
(a) the result of the measurement serves as a basis for determining the price to be paid;
(b) at least one of the parties involved in this sale, which is linked to the measurement, is the consumer or any other party requiring the same level of protection;
(c) all parties involved in this sale accept the result of the measurements at a given time and place.
2.7 The external environment is the environment in which the gauge can be used.
