(72/245/EEC)
THE COUNCIL OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic
Community, and in particular Article 100 thereof;
Having regard to the proposal from the Commission;Having regard to the Opinion of the European Parliament;
Having regard to the Opinion of the Economic and Social Committee;
Whereasthe technical requirementswhich motor vehiclesfitted with a
spark-ignition engine must satisfy pursuant to national laws relate, inter
alia, to the suppression of radio interference produced by such vehi-
cles;
Whereasthos e requirementsdiffer from one Member State to another;
whereas it is therefore necessary that all Member States adopt the samerequirementseither in addition to or in place of their exis ting require-ments, in order, in particular, to allow the EEC type approvalprocedure which wasthe s ubject of the Council Directive of 6 February
1970(
1) on the approximation of the lawsof the Member Statesrelating
to the type approval of motor vehiclesand their trailersto be applied inrespect of each type of vehicle;
Whereasit isdes irable to follow the technical requirementsadopted by
the UN Economic Commission for Europe in its Regulation No 10
(Uniform provisions concerning the approval of vehicles with regard
to radio interference suppression), which is annexed to the Agreementof 20 March 1958 concerning the adoption of uniform conditionsofapproval and reciprocal recognition of approval for motor vehicleequipment and parts(
2);
HAS ADOPTED THIS DIRECTIVE:
Article 1
For the purposes of this Directive, ‘vehicle’ means any motor vehicle
fitted with a high-voltage ignition system, intended for use on theroad, with or without bodywork, having at least four wheels and a
maximum design speed exceeding 25 km/h, with the exception of vehi-
cleswhich run on rails , agricultural tractorsand machinery, and publicworksvehicles .
Article 2
No Member State may refuse to grant EEC type approval or national
type approval of a vehicle on groundsrelating to the radio interference
produced by the electric ignition systems of its propulsion engine orengines if such vehicle is fitted with an interference suppressor meetingthe requirements set out in the Annexes.
Article 3
The Member State which hasgranted type approval s hall take the
necessary measures to be informed of any modification of a part or1972L0245 — EN — 25.07.1989 — 001.001 — 2

characteristic referred to in item 2.2 of Annex I. The competent autho-
rities of that State shall determine whether fresh tests should be carriedout on the modified prototype and a fresh report drawn up. Where such
tests reveal failure to comply with the requirements of this Directive,
the modification shall not be approved.

1. Member States shall put into force the provisions needed in order
to comply with thisDirective within eighteen monthsof itsnotification
and shall forthwith inform the Commission thereof.

8. EXTENSION OF EEC TYPE APPROVAL
8.1.Vehicle typesmodifiedtorunonunleadedpetrol
8.1.1. Approval of a vehicle type modified and/or adjusted solely for the
purpose of making it capable of running on unleaded petrol, as specified
in Directive 85/210/EEC, shall be extended when the manufacturer
certifies, subject to the radio interference suppression for the modified
vehiclesremain within the limitsfor conformity of production, ass peci-
fied in 9 to thisAnnex.
8.2.Vehiclestypesmodifiedforanyotherpurpose
8.2.1. Approval of a vehicle type may be extended to vehicle typesdiffering
with regard to the characteristics listed in 2.2 to this Annex if the
authority granting type approval considers that the modification made
are not likely to have any substantial adverse effect on the radio inter-
ference suppression of the vehicle.
9. CONFORMITY OF PRODUCTION
(9.1)
9.2 When the conformity of a vehicle taken from the series is being veri-
fied, production shall be deemed to conform to the requirements of this
Directive if the levelsmeas ured do not exceed by more than 25 % the
limitspres cribed in item 6.2.2.
9.3 If at least one of the levels measured on the vehicle taken from the
series exceeds the limits prescribed in item 6.2.2 by more than 25 %,

ANNEX II
METHODOF MEASUREMENT OF RAD IO INTERFERENCE
PRODUCEDBYHIGH-VOLTAGEIGNITIONSYSTEMS
1. MEASURING APPARATUS
The measuring equipment shall comply with the requirements of Publication
No 2 (first edition, 1961) of the International Special Committee on Radio
Interference (CISPR) or with the specifications applicable to peak type
measuring apparatus given in CISPR Publication No 5 (first edition, 1967).
Note:Where the available equipment doesnot fully meet all the CISPR
specifications, discrepancies must be clearly stated.
2. EXPRESSION OF RESULTS
The results of measurements must be expressed in µV/m for 120 kHz band-
width. For statistical purposes, the logarithmic unit dB (µV/m) shall be
used. If for certain frequencies the actual bandwidth B (expressed in kHz)
of the measuring apparatus differs slightly from 120 kHz, the readings taken
should be converted to 120 kHz bandwidth through multiplication by a
factor120
B.
3. MEASURING SITE
The measuring site shall be a level area free from appreciable wave-
reflecting surfaces within an ellipse having a major axis of 20 m and a
minor axisof 17·3 m. The antenna and the centre of the engine mus t be
located on the major axis of the ellipse, the plane of symmetry of the
vehicle being parallel to the minor axis. The antenna and the point of inter-
section of the side of the engine nearest to the antenna with the major axis
must each be located at a focal point of the ellipse. The measuring set, or
the test hut or vehicle in which the set is located, may be within the ellipse
but horizontally not closer than 3 m to the antenna, in a direction opposite
to the vehicle being measured. Furthermore, the absence of any extraneous
noise or signal which could materially affect the measurement must be
ensured; a check is therefore made, with the engine stopped, before and
after taking the measurements, which can be considered satisfactory only if
the readings are at least 10 dB above the highest obtained at the pre- and
post-measurement checks.
4. VEHICLE
4.1 Only the ancillary electrical equipment necessary for the running of the
engine shall be operating.
4.2 The engine shall be at its normal operating temperature. During each
measurement, the engine shall be operated as follows:
Number of cylindersMethod of measurement
Peak Quasi-peak
One Above idling 2 500 r.p.m.
More than one Above idling 1 500 r.p.m.
4.3 Measurements shall not be made while rain is falling on the vehicle or
within 10 minutesafter rain hass topped.
5. ANTENNA5.1Height
The centre of the dipole shall be 3 m above the ground.
5.2Distanceofmeasurement
The horizontal distance from the antenna to the nearest metal part of the
vehicle shall be 10 m.1972L0245 — EN — 25.07.1989 — 001.001 — 7
▼B
5.3Antennalocationrelative tovehicle
The antenna shall be placed successively on the left- and right-hand sides of
the vehicle, at two positions of measurement, with the aerial parallel to the
plane of symmetry of the vehicle and in line with the engine. (See
Appendix to thisAnnex.)
5.4Antennaposition
At each of the measuring points, readings shall be taken with the dipole in a
horizontal and in a vertical position. (See Appendix to this Annex.)
5.5Readings
The maximum of four readings shall be taken as the characteristic reading
at the frequency at which the measurements were made.
6. FREQUENCIES
Measurements shall be made within the 40 to 250 MHz range. A vehicle is
considered as very likely to meet the required suppression limits over the
whole frequency range if it meets them at the following six frequencies:
45, 65, 90, 150, 180 and 220 (± 5 MHz). (The 5 MHz tolerance for the
six frequencies chosen should make it possible to avoid interference from
transmissions operating on the nominal frequencies.)1972L0245 — EN — 25.07.1989 — 001.001 — 8

STATISTICAL METHODOF CHECKING RAD IO INTERFERENCE
SUPPRESSION
In order to ensure with an 80% probability that 80% of the vehicles conform to
a specified limit L, the following condition must be satisfied:
xþkSn/C20L
where /C22xx = arithmetic mean of the results on n vehicles
k = statistical factor which depends on n as shown in the
following table:
n = 6 7 8 9 10 11 12
k = 1·42 1·35 1·30 1·27 1·24 1·21 1·20
Sn= standard deviation of results on n vehicles
Sn2= /C6x—/C22xx ðÞ2=n—1ðÞ
x = individual result
L = specified limitSn,x ,/C22xx and L expressed in dB ( µV/m).
If a first sample of n vehicles does not meet the specification, a second sample
of n vehicles shall be tested and the overall results assessed as coming from a
sample of 2n vehicles.1972L0245 — EN — 25.07.1989 — 001.001 — 10
