ANNEX I

ESSENTIAL REQUIREMENTS

A measuring instrument shall provide a high level of metrological protection in order that any party affected can have
confidence in the result of measurement, and shall be designed and manufactured to a high level of quality in respect of
the measurement technology and security of the measurement data.

The requirements that shall be met by measuring instruments are set out below and are supplemented, where appro-
priate, by specific instrument requirements in Annexes MI-001 to MI-010 that provide more detail on certain aspects of
the general requirements.

The solutions adopted in the pursuit of the requirements shall take account of the intended use of the instrument and
any foreseeable misuse thereof.

DEFINITIONS

Measurand

The measurand is the particular quantity subject to measurement.

Influence quantity

An influence quantity is a quantity that is not the measurand but that affects the result of measurement.

Rated Operating Conditions

The rated operating conditions are the values for the measurand and influence quantities making up the normal working
conditions of an instrument.

Disturbance

An influence quantity having a value within the limits specified in the appropriate requirement but outside the specified
rated operating conditions of the measuring instrument. An influence quantity is a disturbance if for that influence
quantity the rated operating conditions are not specified.

Critical change value

The critical change value is the value at which the change in the measurement result is considered undesirable.

Material Measure

A material measure is a device intended to reproduce or supply in a permanent manner during its use one or more
known values of a given quantity.

Direct sales

A trading transaction is direct sales if:

— the measurement result serves as the basis for the price to pay and;

— at least one of the parties involved in the transaction related to measurement is a consumer or any other party

requiring a similar level of protection and;

— all the parties in the transaction accept the measurement result at that time and place.

Climatic environments

Climatic environments are the conditions in which measuring instruments may be used. To cope with climatic
differences between the Member States, a range of temperature limits has been defined.

Utility

A utility is regarded as a supplier of electricity, gas, heat or water.

REQUIREMENTS

1.

Allowable Errors

1.1. Under rated operating conditions and in the absence of a disturbance, the error of measurement shall not exceed
the maximum permissible error (MPE) value as laid down in the appropriate instrument-specific requirements.

Unless stated otherwise in the instrument-specific annexes, MPE is expressed as a bilateral value of the deviation
from the true measurement value.

1.2. Under rated operating conditions and in the presence of a disturbance, the performance requirement shall be as

laid down in the appropriate instrument-specific requirements.

Where the instrument is intended to be used in a specified permanent continuous electromagnetic field the
permitted performance during the radiated electromagnetic field-amplitude modulated test shall be within MPE.

1.3.

The manufacturer shall specify the climatic, mechanical and electromagnetic environments in which the
instrument is intended to be used, power supply and other influence quantities likely to affect its accuracy,
taking account of the requirements laid down in the appropriate instrument-specific annexes.

1.3.1. Climatic environments

The manufacturer shall specify the upper temperature limit and the lower temperature limit from any of the
values in Table 1 unless otherwise specified in the Annexes MI-001 to MI-010, and indicate whether the
instrument is designed for condensing or non-condensing humidity as well as the intended location for the
instrument, i.e. open or closed.

1.3.2. (a) Mechanical environments are classified into classes M1 to M3 as described below.

M1 This class applies to instruments used in locations with vibration and shocks of low significance, e.g. for
instruments fastened to light supporting structures subject to negligible vibrations and shocks trans-
mitted from local blasting or pile-driving activities, slamming doors, etc.

M2 This class applies to instruments used in locations with significant or high levels of vibration and shock,
e.g. transmitted from machines and passing vehicles in the vicinity or adjacent to heavy machines,
conveyor belts, etc.

M3 This class applies to instruments used in locations where the level of vibration and shock is high and

very high, e.g. for instruments mounted directly on machines, conveyor belts, etc.

(b) The following influence quantities shall be considered in relation with mechanical environments:

— Vibration;

— Mechanical shock.

1.3.3. (a) Electromagnetic environments are classified into classes E1, E2 or E3 as described below, unless otherwise laid

down in the appropriate instrument-specific annexes.

E1 This class applies to instruments used in locations with electromagnetic disturbances corresponding to

those likely to be found in residential, commercial and light industrial buildings.

E2 This class applies to instruments used in locations with electromagnetic disturbances corresponding to

those likely to be found in other industrial buildings.

30.4.2004

EN

Official Journal of the European Union

L 135/13

E3 This class applies to instruments supplied by the battery of a vehicle. Such instruments shall comply with

the requirements of E2 and the following additional requirements:

— voltage reductions caused by energising the starter-motor circuits of internal combustion engines,

— load dump transients occurring in the event of a discharged battery being disconnected while the

engine is running.

(b) The following influence quantities shall be considered in relation with electromagnetic environments:

— Voltage interruptions,

— Short voltage reductions,

— Voltage transients on supply lines and/or signal lines,

— Electrostatic discharges,

— Radio frequency electromagnetic fields,

— Conducted radio frequency electromagnetic fields on supply lines and/or signal lines,

— Surges on supply lines and/or signal lines.

1.3.4. Other influence quantities to be considered, where appropriate, are:

— Voltage variation,

— Mains frequency variation,

— Power frequency magnetic fields,

— Any other quantity likely to influence in a significant way the accuracy of the instrument.

1.4. When carrying out the tests as envisaged in this Directive, the following paragraphs apply:

1.4.1. Basic rules for testing and the determination of errors

Essential requirements specified in 1.1 and 1.2 shall be verified for each relevant influence quantity. Unless
otherwise specified in the appropriate instrument-specific annex, these essential requirements apply when each
influence quantity is applied and its effect evaluated separately, all other influence quantities being kept relatively
constant at their reference value.

Metrological tests shall be carried out during or after the application of the influence quantity, whichever
condition corresponds to the normal operational status of the instrument when that influence quantity is
likely to occur.

1.4.2. Ambient humidity

— According to the climatic operating environment in which the instrument is intended to be used either the

damp heat-steady state (non-condensing) or damp heat cyclic (condensing) test may be appropriate.

— The damp heat cyclic test is appropriate where condensation is important or when penetration of vapour will
be accelerated by the effect of breathing. In conditions where non-condensing humidity is a factor the
damp-heat steady state is appropriate.

2.

Reproducibility

The application of the same measurand in a different location or by a different user, all other conditions being
the same, shall result
in the close agreement of successive measurements. The difference between the
measurement results shall be small when compared with the MPE.

L 135/14

EN

Official Journal of the European Union

30.4.2004

3.

Repeatability

The application of the same measurand under the same conditions of measurement shall result in the close
agreement of successive measurements. The difference between the measurement results shall be small when
compared with the MPE.

4.

Discrimination and Sensitivity

A measuring instrument shall be sufficiently sensitive and the discrimination threshold shall be sufficiently low
for the intended measurement task.

5.

Durability

A measuring instrument shall be designed to maintain an adequate stability of its metrological characteristics over
a period of time estimated by the manufacturer, provided that it is properly installed, maintained and used
according to the manufacturer's instruction when in the environmental conditions for which it is intended.

6.

Reliability

A measuring instrument shall be designed to reduce as far as possible the effect of a defect that would lead to an
inaccurate measurement result, unless the presence of such a defect is obvious.

7.

Suitability

7.1. A measuring instrument shall have no feature likely to facilitate fraudulent use, whereas possibilities for unin-

tentional misuse shall be minimal.

7.2. A measuring instrument shall be suitable for its intended use taking account of the practical working conditions
and shall not require unreasonable demands of the user in order to obtain a correct measurement result.

7.3.

The errors of a utility measuring instrument at flows or currents outside the controlled range shall not be unduly
biased.

7.4. Where a measuring instrument is designed for the measurement of values of the measurand that are constant
over time, the measuring instrument shall be insensitive to small fluctuations of the value of the measurand, or
shall take appropriate action.

7.5. A measuring instrument shall be robust and its materials of construction shall be suitable for the conditions in

which it is intended to be used.

7.6. A measuring instrument shall be designed so as to allow the control of the measuring tasks after the instrument
has been placed on the market and put into use. If necessary, special equipment or software for this control shall
be part of the instrument. The test procedure shall be described in the operation manual.

When a measuring instrument has associated software which provides other functions besides the measuring
function, the software that is critical for the metrological characteristics shall be identifiable and shall not be
inadmissibly influenced by the associated software.

8.

Protection against corruption

8.1.

The metrological characteristics of a measuring instrument shall not be influenced in any inadmissible way by the
connection to it of another device, by any feature of the connected device itself or by any remote device that
communicates with the measuring instrument.

8.2. A hardware component that is critical for metrological characteristics shall be designed so that it can be secured.

Security measures foreseen shall provide for evidence of an intervention.

Software that is critical for metrological characteristics shall be identified as such and shall be secured.

Software identification shall be easily provided by the measuring instrument.

Evidence of an intervention shall be available for a reasonable period of time.

8.4. Measurement data, software that

is critical

for measurement characteristics and metrologically important

parameters stored or transmitted shall be adequately protected against accidental or intentional corruption.

8.5.

For utility measuring instruments the display of the total quantity supplied or the displays from which the total
quantity supplied can be derived, whole or partial reference to which is the basis for payment, shall not be able
to be reset during use.

9.

Information to be borne by and to accompany the instrument

9.1.

A measuring instrument shall bear the following inscriptions:

in the case of a self-service arrangement the scale intervals of the main indicating device on the
measuring system and the scale intervals of the self-service device shall be the same and results of measurement
shall not deviate one from another.

5.2.

It shall not be possible to divert the measured quantity in normal conditions of use unless it is readily apparent.

5.3. Any percentage of air or gas not easily detectable in the liquid shall not lead to a variation of error greater than:

— 0,5 % for liquids other than potable liquids and for liquids of a viscosity not exceeding 1 mPa.s, or

ANNEX MI-010

EXHAUST GAS ANALYSERS

The relevant requirements of Annex I,
this Annex and the conformity assessment
procedures listed in this Annex, apply to exhaust gas analysers defined below intended for inspection and professional
maintenance of motor vehicles in use.

DEFINITIONS

Exhaust gas analyser

An exhaust gas analyser is a measuring instrument
that serves to determine the volume fractions of specified
components of the exhaust gas of a motor vehicle engine with spark ignition at the moisture level of the sample
analysed.

These gas components are carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) and hydrocarbons (HC).

The content of hydrocarbons has to be expressed as concentration of n-hexane (C6H14), measured with near-infrared
absorption techniques.

The volume fractions of the gas components are expressed as a percentage (% vol) for CO, CO2 and O2 and in parts per
million (ppm vol).

Moreover, an exhaust gas analyser calculates the lambda value from the volume fractions of the components of the
exhaust gas.

Lambda

Lambda is a dimensionless value representative of the burning efficiency of an engine in terms of air/fuel ratio in the
exhaust gases. It is determined with a reference standardised formula.

SPECIFIC REQUIREMENTS

Instrument Classes

1.

Two classes (0 and I) are being defined for exhaust gas analysers. The relevant minimum measuring ranges for
these classes are shown in Table 1.

Rated operating conditions

2.

The values of the operating conditions shall be specified by the manufacturer as follows:

2.1. For the climatic and mechanical influence quantities:

— A minimum temperature range of 35 °C for the climatic environment;

— The mechanical environment class that applies is M1.

30.4.2004

2.2. For the electrical power influence quantities:

— The voltage and frequency range for the AC voltage supply;

— The limits of the DC voltage supply.

2.3. For the ambient pressure:

— The minimum and the maximum values of the ambient pressure are for both classes: pmin £ 860 hPa,

pmax ‡ 1 060 hPa.

Maximum permissible errors (MPEs)

3.

The MPEs are defined as follows:

3.1. For each of the fractions measured, the maximum error value permitted under rated operating conditions according
to paragraph 1.1 of Annex I is the greater of the two values shown in Table 2. Absolute values are expressed in %
vol or ppm vol, percentage values are percent of the true value.

3.2. The MPE on lambda calculation is 0,3 %. The conventional true value is calculated according to the formula defined
in point 5.3.7.3 of Annex I of Directive 98/69/EC of the EP and the Council relating to measures to be taken
against air pollution by emissions from motor vehicles and amending Council Directive 70/220/EEC (1).

For this purpose, the values displayed by the instrument are used for calculation.

Permissible effect of disturbances

4.

For each of the volume fractions measured by the instrument, the critical change value is equal to the MPE for the
parameter concerned.

5.

The effect of an electromagnetic disturbance shall be such that:

— either the change in the measurement result is not greater than the critical change value laid down in

paragraph 4;

— or the presentation of the measurement result is such that it cannot be taken for a valid result.

Other requirements

6.

The resolution shall be equal to or of one order of magnitude higher than the values shown in Table 3.

9.

The standard deviation of 20 measurements shall not be greater than one third of the modulus of the MPE for each
applicable gas volume fraction.

For measuring CO, CO2 and HC, the instrument, including the specified gas handling system, must indicate 95 % of
the final value as determined with calibration gases within 15 seconds after changing from a gas with zero content,
e.g. fresh air. For measuring O2, the instrument under similar conditions must indicate a value differing less than
0,1 % vol from zero within 60 seconds after changing from fresh air to an oxygen-free gas.

The components in the exhaust gas, other than the components whose values are subject to the measurement, shall
not affect the measurement results by more than the half of the modulus of the MPEs when those components are
present in the following maximum volume fractions:

6 % vol CO,

16 % vol CO2,

10 % vol O2,

5 % vol H2,

0,3 % vol NO,

2 000 ppm vol HC (as n-hexane),

water vapor up to saturation.

10. An exhaust gas analyser shall have an adjustment facility that provides operations for zero-setting, gas calibration
and internal adjustment. The adjustment facility for zero-setting and internal adjustment shall be automatic.

11. For automatic or semi-automatic adjustment facilities, the instrument shall be unable to make a measurement as

long as the adjustments have not been made.

12. An exhaust gas analyser shall detect hydrocarbon residues in the gas handling system. It shall not be possible to
carry out a measurement if the hydrocarbon residues, present before any measurement, exceeds 20 ppm vol.

13. An exhaust gas analyser shall have a device for automatically recognising any malfunctioning of the sensor of the

oxygen channel due to wear or a break in the connecting line.

14.

If the exhaust gas analyser is capable to operate with different fuels (e.g. petrol or liquefied gas), there shall be the
possibility to select the suitable coefficients for the Lambda calculation without ambiguity concerning the appro-
priate formula.

CONFORMITY ASSESSMENT

The conformity assessment procedures referred to in Article 9 that the manufacturer can choose between are:

B + F or B + D or H1.
