(71/127/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(
1);
Having regard to the Opinion of the Economic and Social Committee(2);
Whereas the technical requirements which motor vehicles must satisfy
pursuant to national laws relate, inter alia , to their rear-view mirrors;
Whereas those requirements differ from one Member State to another;
whereas it is therefore necessary that all Member States adopt the samerequiremen ts either inadditionto or inplace of their existin g
requirements, in order, in particular, to allow the EEC type-approval
procedure which was the subject of the Council Directive of 6 February1970(
3) onthe approximationof the laws of the Member States relatin g
to the type-approval of motor vehicles and their trailers to be applied inrespect of each type of vehicle;
Whereas rules onrear-view mirrors should lay downrequiremen ts
concerning not only how such mirrors should be fitted on vehicles butalso their construction;
Whereas a harmonised type-approval procedure for rear-view mirrors
makes it possible for each Member State to check compliance with the
common construction and testing requirements and to inform the other
Member States of its findings by sending a copy of the type-approvalcertificate completed for each type of rear-view mirror; whereas theplacing of an EEC type-approval mark on all mirrors manufactured inconformity with the approved type obviates any need for technical
checks onthese mirrors inthe other Member States;
HAS ADOPTED THIS DIRECTIVE:
Article 1
1. Each Member State shall approve any type of rear-view mirror
which satisfies the construction and testing requirements laid down in
item 2 of Annex I.
2. The Member State which has granted type approval shall take the
measures required in order to verify, in so far as is necessary and if needbe inco-operationwith the competen t authorities inthe other MemberStates, that productionmodels con form to the approved type. Such
verificationshall be limited to spot checks.
Article 2
Member States shall issue to the manufacturer, or to his authorised
representative, an EEC type-approval mark which shall conform to themodel shown in item 2.6 of Annex I, for each type of rear-view mirrorwhich they approve pursuant to Article 1.1971L0127 — EN — 04.03.1971 — 000.001 — 2

▼B
Member States shall take all appropriate measures to prevent the use of
marks liable to create confusion between rear-view mirrors which havebeen type-approved pursuant to Article 1 and other mirrors.
Article 3
1. No Member State may prohibit the placing on the market of rear-
view mirrors on grounds relating to their construction or method offunctioning if they bear the EEC type-approval mark.
2. Nevertheless, this provision shall not prevent a Member State from
taking such measures in respect of rear-view mirrors bearing the EECtype-approval mark which, by their design, do not conform to theapproved prototype.
That State shall inform the other Member States and the Commission
forthwith of the measures taken, specifying the reasons for its decision.The provisions of Article 5 shall also apply.
There shall be failure to conform to the approved prototype, within the
meaning of paragraph 1 above, where the requirements of items 2.1, 2.2or 2.4 of Annex I are not observed.
Article 4
The competent authorities of each Member State shall within one month
send to the competent authorities of the other Member States a copy ofthe type-approval certificates completed for each type of rear-view
mirror which they approve or refuse to approve.
Article 5
1. If the Member State which has granted EEC type-approval finds
that a number of rear-view mirrors bearing the same type-approval markdo not conform to the type which it has approved, it shall take thenecessary measures to ensure that production models conform to theapproved type. The competent authorities of that State shall advise those
of the other Member States of the measures taken, which may, where
necessary, extend to withdrawal of EEC type-approval. The saidauthorities shall take the same measures if they are informed by thecompetent authorities of another Member State of such failure toconform.
2. The competent authorities of Member States shall inform each
other within one month of any withdrawal of EEC type-approval, and ofthe reasons for such measure.
3. If the Member State which has granted EEC type-approval
disputes the failure to conform notified to it, the Member Statesconcerned shall endeavour to settle the dispute. The Commission shall
be kept informed and shall, where necessary, hold appropriate
consultations for the purpose of reaching a settlement.
Article 6
All decisions taken pursuant to the provisions adopted in implementa-
tionof this Directive which refuse or withdraw type-approval for a rear-view mirror or prohibit its use shall set out indetail the reason s onwhichthey are based. A decision shall be notified to the party concerned, whoshall at the same time be informed of the remedies available to him
un der the laws inforce inthe Member States an d of the time limits
allowed for the exercise of such remedies.
Article 7
No Member State may refuse to grant EEC type-approval or national
type-approval of a vehicle on grounds relating to its rear-view mirrors ifthese bear the EEC type-approval mark and are fitted in accordance withthe requirements laid down in item 3 of Annex I.1971L0127 — EN — 04.03.1971 — 000.001 — 3

betweenmoto the total mass m of the pendulum and the distance
‘1’ between the centre of gravity of the pendulum and its axis of
rotationis expressed as
mo¼m1
aÞ:
2.4.2.2. Descriptionof the test
2.4.2.2.1. Rear-view mirrors are clamped to the support insucha waythat the
latter cannot obstruct the movement of the movable parts of the
rear-view mirror. The procedure used to clamp the rear-view mirror
to the support and to position the arm is that recommended by the
person submitting the rear-view mirrors for testing.
2.4.2.2.2. When the rear-view mirror has a device for adjusting the distance
inrelationto the base, the device must be set at the min imum
value.
2.4.2.2.3. The test consists in allowing the hammer to fall from a height
corresponding to a pendulum angle of 60º from the vertical so that
the hammer strikes the rear-view mirror at the moment when the
pendulum reaches the vertical position, the hammer's point of
impact being on a line passing horizontally to the centre of
percussionof the pen dulum.
2.4.2.2.4. The rear-view mirrors are subjected to impact inthe followin g
different conditions:
2.4.2.2.4.1. Interior rear-view mirrors
Test 1 — Perpendicularly to the surface of the mirror, the point of
impact being such that the impact produced on the mirror passes
through the point at which the holder is attached to the stem or the
mounting. The impact is directed on the reflecting surface.1971L0127 — EN — 04.03.1971 — 000.001 — 7
▼B
Test 2 — Onthe edge of the holder insuch a way that the impact
produced makes an angle of 45º with the plane of the mirror and is
situated in the horizontal plane passing through the point at which
the holder is attached to the stem or the mounting. The impact is
directed onthe reflectin g surface.
2.4.2.2.4.2. Exterior rear-view mirrors
Test 1 — Perpendicularly to the surface of the mirror, the point of
impact being such that the impact produced on the mirror passes
through the point at which the holder is attached to the stem or the
mounting.
Test 1′— At the back of the mirror, on its stem or mounting (the
hammer being at the same distance from the clamping plane as in
Test 1 and the mirror being perpendicular to the trajectory of the
centre of percussion).
Test 2 — Onthe edge of the holder insuch a way that the impact
produced makes an angle of 45º with the plane of the mirror and is
in the horizontal plane passing through the point at which the
holder is attached to the stem or the mounting. The impact is
directed onthe reflectin g surface.
2.4.2.2.4.3. General observations2.4.2.2.4.3.1. The centre of the mirror is taken as the reference point when the
devices tested do not have any clearly defined mounting or stem, or
when the point of attachment is on the periphery of the mirror.
2.4.2.2.4.3.2. If it is not possible to carry out the test described in item 2.4.2.2,
the point of impact is moved, in the plane of symmetry of the
pendulum, in such a way that the lowest point of the hammer is
40 mm from the clamping plane.
2.4.3. Bending test on the holder fixed to the stem
2.4.3.1. Descriptionof the test
The holder is placed horizon tally ina device insuch a way that the
stem or the mounting can be clamped securely. In the direction of
the greatest dimension of the holder, the end nearest to the point of
fixing on the stem is immobilised by means of a fixed stop 15 mm
wide, covering the entire width of the holder.
At the other end, a stop identical to the one described above is
placed onthe holder so that the specified test load canbe applied to
it (Figure 2).1971L0127 — EN — 04.03.1971 — 000.001 — 8
▼B
Exampleofbendingtestapparatusforrear-viewmirrorholders
Fig. 2
2.4.3.2. The test load is 25 kg. It is applied for one minute.
2.5.Interpretationofresults
2.5.1. In all the tests described in item 2.4.2 the pendulum must continue
to swing after impact to a point forming an angle of ►C1at least
20º◄with the vertical.
2.5.2. Should there be a breakage of the stems or the mounting of the
rear-view mirror during the tests described in item 2.4.2 the part
remaining must not project from the base by more than 1 cm. If the
stem or mounting breaks off, the remaining part of the base must
not form a dangerous projection.
2.5.3. The mirror must not break during the tests described in items 2.4.2
and 2.4.3. However, breakage of the mirror will be allowed if one
of the following conditions is fulfilled:
2.5.3.1. The fragments of glass still adhere to the back of the holder or to a
surface firmly attached to the holder, provided that anarea n o
greater than5 mm inwidth comes un stuck.
2.5.3.2. The mirror is made of safety glass.
2.6.Typeapprovalmark
2.6.1. The type approval mark shall be made up of a rectangle, within
which shall be placed the letter ‘e’ followed by the distinguishing
number or letter of the country which has granted the type approval
(1 for Germany, 2 for France, 3 for Italy, 4 for the Netherlands, 6
for Belgium, and L for Luxembourg). At any point in the proximity
of this rectangle there shall be placed a type approval number
corresponding to the number of the approval certificate completed
for the prototype.
2.6.2. The type approval mark (symbol and number) shall be placed on a
mainpart of the rear-view mirror insuch a way that it is in delible
and clearly visible even after the rear-view mirror has been fitted
ona vehicle.1971L0127 — EN — 04.03.1971 — 000.001 — 9

Directive onthe approximationof the laws of the Member States
relating to the type approval of motor vehicles and their trailers.1971L0127 — EN — 04.03.1971 — 000.001 — 10
(1) The numbers in the diagram are for guidance only.
▼B
3.3.3. Inthe case of left-han d drive vehicles the prescribed exterior rear-
view mirror must be fitted to the left side of the vehicle insuch a
way that there is an angle of not more than 55º between the vertical
longitudinal median of the vehicle and the vertical plane which
passes through the centre of the rear-view mirror and through the
centre of the segment between the ocular points of the driver.
3.3.4. The rear-view mirror must not protrude beyond the external
bodywork of the vehicle substantially more than is necessary to
obtainthe fields of visionlaid downinitem 3.5.
3.3.5. Where the bottom edge of anexterior rear-view mirror is less than

3.3.6. Subject to the requirements of items 3.3.4 and 3.3.5, rear-view
mirrors may project beyond the permissible maximum widths of
vehicles.
3.4.Adjustment
3.4.1. The driver must be able to adjust the interior rear-view mirror from
his driving position.
3.4.2. It must be possible to adjust the exterior rear-view mirror situated

outside(1).
3.4.3. The requirements of item 3.4.2 do not apply to exterior rear-view
mirrors which can be returned to their former position without any
adjustment being necessary, after having been knocked out of
alignment.
3.5.Fieldofvision
3.5.1. General
The fields of vision defined below must be established using
binocular vision, the observer's eyes being at the ‘driver's ocular
points’ as defined in item 1.7 above. The fields of vision shall be

ANNEX III (1)
TESTPROCEDUREFORDETERMININGTHEHPOINT
1. Definition
The ‘H’ point, which indicates the position in the passenger compartment
of a seated occupant, is the trace, in a longitudinal vertical plane, of the
theoretical axis of rotationbetweenthe leg an d the torso of a human
body, represented by a manikin.
2. Determination of H points
2.1. An H point shall be determined for the driver's seat.
(2.1.1.)
(2.1.2.)
2.2. For each determination of an H point the seat concerned shall be placed
in the normal position for driving provided by the manufacturer, the
back, if inclinable, being set up in a position close to the vertical.
3. Descriptionof the man ikin
3.1. A three-dimensional manikin with the weight and shape of an adult male
of average height shall be used. Such a manikin is depicted in Figures 1
and 2.
3.2. This manikin shall comprise:3.2.1. two components, one simulating the back and the other the seat of the
body, hinged along an axis representing the axis of rotation between the
torso and the thigh. The trace of this axis on the side of the manikin is its
H point;
3.2.2. two components simulating the legs and hinged in relation to the
component simulating the seat;
3.2.3. two components simulating the feet and connected to the legs by hinges
simulating the ankles;
3.2.4. in addition, the component simulating the seat shall be provided with a
level enabling its transverse orientation to be verified.
3.3. Weights each representing the weight of one of the components of the
body shall be placed at appropriate points constituting the relevant
centres of gravity, so as to bring the total weight of the manikin up to
about 75·8 kgf (74·4 daN). Details of the various weights are giveninthe
table of Figure 2.
4. Setting up the manikin
The three-dimensional manikin shall be set up in the following manner:
4.1. The vehicle is levelled and the seat is adjusted as prescribed in item 2.2.
4.2. The seat to be tested is covered with a piece of fabric to facilitate correct
setting up of the manikin.
4.3. The manikin is placed on the seat.
4.4. The feet of the manikin are placed as follows:
4.4.1. The right foot is placed onthe accelerator pedal inthe positionof rest
and the left foot is so arranged that the level verifying the transverse
orientation of the seat of the manikin is restored to the horizontal;1971L0127 — EN — 04.03.1971 — 000.001 — 15
(1) The text of Annex III is similar to that of Regulation No 14; in particular the breakdown
into items is the same. For this reason, where an item of Regulation No 14 has nocounterpart in this Directive, its number is given in Annex III in brackets as a token
entry.
▼B
(4.4.2.)
(4.4.3.)
4.5. The weights are placed onthe thighs, the tran sverse level of the
manikin's seat is restored to the horizontal, and the weights are placed on
the component simulating the seat.
4.6. The manikin is moved away from the seat back by using the hinged knee
bar and the back of the manikin is tilted forward. The manikin is
repositioned on the seat of the vehicle by sliding the seat of the manikin
rearwards until resistance is encountered, and the back of the manikin is
thenreplaced again st the seat back.
4.7. A load of about 10·2 kgf (10 daN) is applied horizontally to the manikin
twice. The direction and point of application of the load are shown by a
black arrow inFigure 2.
4.8. The weights on the right and left sides and then the torso weights are
placed in position, the transverse level of the manikin being kept
horizontal.
4.9. The manikin's transverse level being kept horizontal, the manikin's back
is tilted forwards until the torso weights are above the H point, so as to
eliminate any friction with the seat back.
4.10. The manikin's back is gently moved rearwards again so as to complete
the setting up operation. The transverse level of the manikin should be
horizontal. If it is not, repeat the process described above.
5. Results
5.1. When the manikin has been set up as described in item 4, the H point of
the seat is the H point on the manikin.
5.2. The Cartesian co-ordinates of the H point shall each be measured
accurately to within 1 mm, as shall the co-ordinates of characteristic and
