— height 165 mm.
2.LOCATIONOFTHESPACEFORMOUNTINGANDTHEFIXING
OF THE PLATES
The space for mounting shall be such that, after correct fixing, the plates
shall have the following characteristics:
2.1.Position of the plate in relation to the width of the vehicle
The centre point of the plate may not be situated to the right of the plane
of symmetry of the tractor in Member States where traffic drives on theright or to the left of that plane where traffic drives on the left.
In Member States where traffic drives on the right, the left-hand edge of
the plate may not be situated to the left of the vertical plane which isparallel to the plane of symmetry of the tractor and which touches theextreme outer edge of the vehicle.
In Member States where traffic drives on the left, the right-hand edge of
the plate may not be situated to the right of the vertical plane which isparallel to the plane of symmetry of the tractor and which touches theextreme outer edge of the vehicle.
2.2.Positionoftheplateinrelationtothelongitudinalplaneofsymmetry
of the tractor
The plate shall be perpendicular or practically perpendicular to the plane
of symmetry of the tractor.
2.3.Position of the plate in relation to the vertical plane
The plate shall be vertical within a tolerance of 5 °. However, where the
shape of the tractor so requires, it may be inclined to the vertical:
2.3.1. at not more than 30 °when the surface bearing the registration number is
inclined upwards, provided that the height of the upper edge of the plate isnot more than 1 ·20 metres from the ground;
2.3.2. at not more than 15 °when the surface bearing the registration number is

ANNEX VI
I.PERMISSIBLE SOUND LEVELS
I.1.Limits
The sound level of the tractors referred to in Article 1 of this Directive,
when measured under the conditions set out in this Annex, may notexceed the following levels:
89 dB (A) for tractors with an unladen weight exceeding 1 ·5 metric
tons;
85 dB (A) for tractors with an unladen weight not exceeding 1 ·5 metric
tons.
I.2.Measuring instruments
The noise emitted by tractors shall be measured by means of a sound-
level meter of the type described in Publication 179, 1st Edition (1965)of the InternationalEl ectrotechnicalCommission.
I.3.Conditions of measurement
Measurements shall be made on unladen tractors in a sufficiently silent
and open area (ambient noise and wind noise at least 10 dB (A) belowthe noise being measured).
This area may take the form, for instance, of an open space of 50 metre
radius having a centralpart of at l east 20 metres radius which ispractically level; it may be surfaced with concrete, asphalt, or similarmaterialand may not be covered with powdery snow, tal lgrass, l oosesoilor ashes.
The surface of the test track shall be such as not to cause excessive
tyre noise. This condition applies only to measurement of the noisemade by tractors in motion.
Measurement shall be carried out in fine weather with little wind. No
person other than the observer taking the readings from the apparatusmay remain near the tractor or the microphone, as the presence ofspectators near either the tractor or the microphone may considerablyaffect the readings from the apparatus. Marked fluctuations of thepointer which appear to be unrelated to the characterstics of the generalsound level shall be ignored in taking readings.
I.4.Method of measurement
I.4.1. Measurement of noise of tractors in motion (for type-approval).
At least two measurements shall be made on each side of the tractor.
Preliminary measurements may be made for adjustment purposes butshall be disregarded.
The microphone shall be situated 1 ·2 metres above ground level at a
distance of 7 ·5 metres from the path of the tractor’s centre line, CC,
measured along the perpendicular PP' to that line (figure 1).
Two lines AA'and BB',parallel to line PP'and situated respectively 10
metres forward and 10 metres rearward of the line, shall be marked outon the test track. Tractors shall approach line AA' at a steady speed, asspecified below. The throttle shall then be fully opened as rapidly aspracticable and held in the fully opened position until the rear of thetractor (
1) crosses line BB'; the throttle shall then be closed again as
rapidly as possible.
The maximum sound level recorded shall constitute the result of the
measurement.
I.4.1.1. The test speed shall be three-quarters of the maximum speed which can
be attained in the highest gear used for road movement.
(1) If the tractor includes a trailer, this shall not be taken into account in determining
when line BB' is crossed.

I.4.1.2. Interpretation of results
I.4.1.2.1. To take account of inaccuracies in the measuring instruments, the
result obtained from each measurement shall be determined bydeducting 1 dB (A) from the meter reading.
I.4.1.2.2. Measurements shall be considered valid if the difference between two
consecutive measurements on the same side of the tractor does notexceed 2 dB (A).
I.4.1.2.3. The highest sound level measured shall constitute the test result.
Should that result exceed by 1 dB (A) the maximum permissible soundlevel for the category of tractor tested, two further measurements shallbe made. Three of the four measurements thus obtained must fallwithin the prescribed limits.

I.4.2. Measurement of noise of stationary tractors (not required for type-
approval).
I.4.2.1. Position of sound-level meter
Measurements shall be made at point X (shown in figure 2) at a
distance of 7 metres from the nearest surface of the tractor.
The microphone shall be situated 1 ·2 metres above ground level.
I.4.2.2. Number of measurements
At least two measurements shall be made.
I.4.2.3. Tractor test conditions
The engine of a tractor without a speed governor shall be run at
three-quarters of the rpm speed at which, according to the tractormanufacturer, it develops its maximum power. The rpm speed of theengine shall be measured by means of an independent instrument, e.g.a roller bed and a tachometer. If the engine is fitted with a governorpreventing the engine from exceeding the speed at which it develops
1974L0151 — EN — 21.12.1982 — 001.001 — 11

its maximum power, it shall be run at the maximum speed permittedby the governor.Before taking any measurements, the engine shall be brought to itsnormalrunning temperature.
I.4.2.4. Interpretation of results
All sound-level readings recorded shall be given in the report.The method used to calculate the engine power shall also be shownwhere possible. The state of loading of the tractor must also be given.The measurements shall be considered valid if the difference betweentwo consecutive measurements on the same side of the tractor does notexceed 2 dB (A).The maximum figure recorded shall constitute the result of the meas-urement.

II.EXHAUST SYSTEM(SILENCER)
II.1. If the tractor is fitted with a device designed to reduce the exhaust
noise (silencer), the requirements of this Item II shall apply. If the inletof the engine is fitted with an air filter which is necessary in order toensure compliance with the permissible sound level, the filter shall beconsidered to be part of the silencer, and the requirements of this ItemII shall also apply to that filter.
II.2. A drawing of the exhaust system must be annexed to the tractor
type-approvalcertificate
II.3. The silencer must be marked with a reference to its make and type
which is clearly legible and indelible.
II.4. The use of fibrous absorbent materialis permitted in the construction
of silencers only if the following conditions are fulfilled:
II.4.1. The fibrous absorbent materialmay not be pl aced in those parts of the
silencer through which gases pass;
II.4.2. Suitable devices must ensure that the fibrous absorbent material is kept
in place for the whole time that the silencer is being used;
1974L0151 — EN — 21.12.1982 — 001.001 — 12
