TECHNICAL REQUIREMENTS FOR HEADLAMPS (1)

GENERAL SPECIFICATIONS

5.1.

Each sample shall conform to the specifications set forth in paragraphs 6 to 8 below.

5.2.

Headlamps shall be so made as to retain their prescribed photometric characteristics and to remain
in good working order when in normal use, in spite of the vibrations to which they may be subjected.

5.2.1.

Headlamps shall be fitted with a device enabling them to be so adjusted on the vehicles as to com-
ply with the rules applicable to them. Such a device need not be fitted on units in which the reflec-
tor and the diffusing lens cannot be separated, provided the use of such units is confined to vehicles
on which the headlamp setting can be adjusted by other means.

Where a headlamp providing a passing beam and a headlamp providing a driving beam, each
equipped with its own filament lamp, are assembled to form a composite unit the adjusting device
shall enable each optical system individually to be duly adjusted.

5.2.2.

However, these provisions shall not apply to headlamp assemblies whose reflectors are indivisible.
For this type of assembly the requirements of paragraph 6.3 of this Regulation apply.

5.3.

5.4.

5.5.

5.6.

5.7.

5.8.

The headlamp shall be equipped with filament lamp(s) approved according to Regulation No 37.
Any Regulation No 37 filament lamp may be used, provided that no restriction on the application
is made in the table of contents of Regulation No 37 (2).

The components by which a filament lamp is fixed to the reflector shall be so made that, even in
darkness, the filament lamp can be fixed in no position but the correct one (3).

The filament lamp holder shall conform to the characteristics given in IEC Publication 61-2,
third edition, 1969. The holder data sheet relevant to the category of filament lamp used, applies.

Headlamps designed to satisfy the requirements both of right-hand and of left-hand traffic may be
adapted for traffic on a given side of the road either by an appropriate initial setting when fitted on
the vehicle or by selective setting by the user. Such initial or selective setting may consist, for
example, of fixing either the optical unit at a given angle on the vehicle or the filament lamp at a
given angle in relation to the optical unit. In all cases, only two different and clearly distinct settings,
one for right-hand and one for left-hand traffic, shall be possible, and the design shall preclude inad-
vertent shifting from one setting to the other or setting in an intermediate position. Where two dif-
ferent setting positions are provided for the filament lamp, the components for attaching the filament
lamp to the reflector must be so designed and made that, in each of its two settings, the filament
lamp will be held in position with the precision required for headlamps designed for traffic on only
one side of the road. Conformity with the requirements of this paragraph shall be verified by visual
inspection and, where necessary, by a test fitting.

Complementary tests shall be done according to the requirements of annex 4 to ensure that in use
there is no excessive change in photometric performance.

If the lens of the headlamp is of plastic material, tests shall be done according to the requirements of
annex 6.

(1) Technical requirements for filament lamps: see Regulation No 37.
(2) HIR1 and/or H9 filament lamps shall only be permitted to produce passing beam in conjunction with the installation of
headlamp cleaning device(s) conforming to Regulation No 45. In addition, with respect to vertical inclination, the pro-
vision of paragraph 6.2.6.2.2 of Regulation No 48, 01 series of amendments, shall be applied when these lamps are
installed.

(3) A headlamp is regarded as satisfying the requirements of this paragraph if the filament lamp can be easily fitted into the

headlamp and the positioning lugs can be correctly fitted into their slots even in darkness.

L 330/175

5.9.

On headlamps designed to provide alternately a driving beam and a passing beam, or a passing beam
and/or a driving beam designed to become bend lighting, any mechanical, electromechanical or other
device incorporated in the headlamp for these purposes shall be so constructed that:

5.9.1.

the device is strong enough to withstand 50 000 operations without suffering damage despite the
vibrations to which it may be subjected in normal use;

5.9.2.

in the case of failure the illumination above the line H-H shall not exceed the values of a passing
beam according to paragraph 6.2.5; in addition, on headlamps designed to provide a passing and/or
a driving beam to become a bend lighting, a minimum illumination of at least 5 lux shall be fulfilled
in test point 25 V (VV line, D 75 cm);

5.9.3.

either the passing beam or the driving beam shall always be obtained without any possibility of the
mechanism stopping in between two positions;

5.9.4.

the user cannot, with ordinary tools, change the shape or position of the moving parts.

6.

ILLUMINATION

6.1.

General provisions

6.1.1.

6.1.2.

6.1.3.

Headlamps shall be so made that they give adequate illumination without dazzle when emitting the
passing beam, and good illumination when emitting the driving beam. Bend lighting may be pro-
duced by activating one additional light source being part of the passing beam headlamp.

The illumination produced by the headlamp shall be determined by means of a vertical screen set
up 25 m forward of the headlamp and at right angles to its axes as shown in annex 3 to this
Regulation.

The headlamps shall be checked by means of an uncoloured standard (étalon) filament lamp designed
for a rated voltage of 12 V. During the checking of the headlamp, the voltage at the terminals of the
filament lamp shall be regulated so as to obtain the reference luminous flux as indicated at the rel-
evant data sheet of Regulation No 37.

6.1.4.

The headlamp shall be considered acceptable if it meets the requirements of this paragraph 6 with
at least one standard (étalon) filament lamp, which may be submitted with the headlamp.

6.2.

Provisions concerning passing beams

6.2.1.

The passing beam must produce a sufficiently sharp ‘cut-off’ to permit a satisfactory adjustment with
its aid. The ‘cut-off’ must be a horizontal straight line on the side opposite to the direction of the
traffic for which the headlamp is intended; on the other side, it must not extend beyond either the
broken line HV H1 H4 formed by a straight line HV H1 making a 45° angle with the horizontal and
the straight line H1 H4, 25 cm above the straight line hh, or the straight line HV H3, inclined at an
angle of 15° above the horizontal (see annex 3). A cut-off extending beyond both line HV H2 and
line H2 H4 and resulting from a combination of the two above possibilities shall in no circumstances
be permitted.

6.2.2.

The headlamp shall be so aimed that:

6.2.2.1.

in the case of headlamps designed to meet the requirements of right-hand traffic, the ‘cut-off’ on the
left-half of the screen (1) is horizontal and, in the case of headlamps designed to meet the require-
ments of left-hand traffic, the ‘cut-off’ on the right-half of the screen is horizontal;

(1) The test screen must be sufficiently wide to allow examination of the ‘cut-off’ over a range of at least 5° on either side of

the line vv.

L 330/176

EN

Official Journal of the European Union

16.12.2005

6.2.2.2.

this horizontal part of the ‘cut-off’ is situated on the screen 25 cm below the level hh (see annex 3);

6.2.2.3.

the ‘elbow’ of the ‘cut-off’ is on line vv (1).

6.2.3. When so aimed, the headlamp need, if its approval is sought solely for provision of a passing
beam (2), comply only with the requirements set out in paragraphs 6.2.5 to 6.2.7 and 6.2.9 below;
if it is intended to provide both a passing beam and a driving beam, it shall comply with the require-
ments set out in paragraphs 6.2.5 to 6.2.7 and 6.3.

6.2.4. Where a headlamp so aimed does not meet the requirements set out in paragraphs 6.2.5 to 6.2.7
and 6.3, its alignment may be changed, provided that the axis of the beam is not displaced laterally
by more than 1° (= 44 cm) to the right or left (3).

To facilitate alignment by means of the ‘cut-off’, the headlamp may be partially occulted in order to
sharpen the ‘cut-off’.

6.2.5.

The illumination produced on the screen by the passing beam shall meet the following requirements:

6.2.6.

There shall be no lateral variations detrimental to good visibility in any of the zones I, II, III and IV.

6.2.7.

The illumination values in zones ‘A’ and ‘B’ as shown in figure C in annex 3 shall be checked by the
measurement of the photometric values of points 1 to 8 on this figure; these values shall lie within
the following limits (4):

1 + 2 + 3 ≥ 0,3 lux, and

4 + 5 + 6 ≥ 0,6 lux, and

0,7 lux ≥ 7 ≥ 0,1 lux and

0,7 lux ≥ 8 ≥ 0,2 lux.

(1) If the beam does not have a cut-off with a clear ‘elbow’, the lateral adjustment shall be effected in the manner which best
satisfies the requirements for illumination at points 75 R and 50 R for right-hand traffic and for points 75 L and 50 L for
left-hand traffic.

(2) Such a special ‘passing beam’ headlamp may incorporate a driving beam not subject to requirements.
(3) The limit of realignment of 1° towards the right or left is not incompatible with upward or downward vertical realign-
ment. The latter is limited only by the requirements of paragraph 6.3. However, the horizontal part of the ‘cut-off’ should
not extend beyond the line hh (the provisions of paragraph 6.3. are not applicable to headlamps intended to meet the
requirements of this Regulation only for provision of a passing beam).

(4) Illumination values in any point of zones A and B, which also lies within zone III, shall not exceed 0,7 lux.

L 330/177

6.2.8.

Headlamps designed to meet the requirements of both right-hand and left-hand traffic must, in each
of the two setting positions of the optical unit or of the filament lamp, meet the requirements set
forth above for the corresponding direction of traffic.

6.2.9.

The requirements in paragraph 6.2.5 above shall also apply to headlamps designed to provide bend
lighting.

If bend lighting is obtained by:

6.2.9.1.

swivelling the passing beam or moving horizontally the kink of the elbow of the cut-off, the mea-
surements shall be carried out after the complete headlamp assembly has been re-aimed horizon-
tally, e.g. by means of a goniometer;

6.2.9.2. moving one or more optical parts of the headlamp without moving horizontally the kink of the
elbow of the cut-off, measurements shall be carried out with these parts being in their extreme oper-
ating position;

6.2.9.3. means of one additional light source without moving horizontally the kink of the elbow of the cut-

off, measurements shall be carried out with this light source activated.

6.3.

Provisions concerning driving beams

6.3.1.

In the case of a headlamp designed to provide a driving beam and a passing beam, measurements of
the illumination produced on the screen by the driving beam shall be taken with the same head-
lamp alignment as for measurements under paragraphs 6.2.5 to 6.2.7 above; in the case of a head-
lamp providing a driving beam only, it shall be so adjusted that the area of maximum illumination
is centred on the point of intersection of lines hh and vv; such a headlamp need meet only the
requirements referred to in paragraph 6.3. Where more than one light source is used to provide the
driving beam, the combined functions shall be used to determine the maximum value of the illu-
mination (EM).

In the case of headlamps with adjustable reflector the requirements of paragraphs 6.2 and 6.3 are
applicable for each mounting position indicated according to paragraph 2.1.3. For verification the
following procedure shall be used:

Each applied position is realized on the test goniometer with respect to a line joining the centre of
the light source and point HV on a aiming screen. The adjustable reflector is then moved into such
a position that the light pattern on the screen corresponds to the aiming prescriptions of para-
graphs 6.2.1 to 6.2.2.3 and/or 6.3.1;

with the reflector initially fixed according to paragraph 6.4.1, the headlamp must meet the relevant
photometric requirements of paragraphs 6.2 and 6.3;

additional tests are made after the reflector has been moved vertically ± 2° or at least into the maxi-
mum position, if less than 2°, from its initial position by means of the headlamps adjusting device.
Having re-aimed the headlamp as a whole (by means of the goniometer for example) in the corre-
sponding opposite direction the light output in the following directions shall be controlled and lie
within the required limits:

passing beam: points HV and 75 R (75 L respectively);

driving beam: EM and point HV (percentage of EM).

if the applicant has not indicated more than one mounting position, the procedure of para-
graphs 6.4.1 to 6.4.3 shall be repeated for all other positions;

if the applicant has not asked for special mounting positions, the headlamp shall be aimed for mea-
surements of paragraphs 6.2 and 6.3 with the headlamps adjusting device in its mean position. The
additional test of paragraph 6.4.3 shall be made with the reflector moved into its extreme positions
(instead of ± 2°) by means of the headlamps adjusting device.

The screen illumination values mentioned in paragraphs 6.2.5 to 6.2.7 and 6.3 above shall be mea-
sured by means of a photoreceptor, the effective area of which shall be contained within a square of
65 mm side.

COLOUR

The colour of the light emitted shall be white. Expressed in CIE trichromatic coordinates, the light
of the beams shall be in the following boundaries:

Test mixture

1.2.1.1.1. For headlamp with the outside lens in glass:

The mixture of water and a polluting agent to be applied to the headlamp shall be composed of:

9 parts by weight of silica sand with a particle size of 0-100 μm, 1 part by weight of vegetal carbon dust (beech-
wood) with a particle size of 0-100 μm, 0,2 parts by weight of NaCMC (1), and an appropriate quantity of dis-
tilled water, with a conductivity of ≤ 1 mS/m. The mixture must not be more than 14 days old.

1.2.1.1.2. For headlamp with outside lens in plastic material:

The mixture of water and polluting agent to be applied to the headlamp shall be composed of:

9 parts by weight of silica sand with a particle size of 0-100 μm, 1 part by weight of vegetal carbon dust (beech-
wood) with a particle size of 0-100 μm, 0,2 part by weight of NaCMC (1), 13 parts by weight of distilled water
with a conductivity of ≤ 1 mS/m, and 2 ± 1 parts by weight of surface-actant (2). The mixture must not be more
than 14 days old.

1.2.1.2.

Application of the test mixture to the headlamp

The test mixture shall be uniformly applied to the entire light-emitting surface of the headlamp and then left to
dry. This procedure shall be repeated until the illumination value has dropped to 15-20 per cent of the values

TEST FOR CHANGE IN VERTICAL POSITION OF THE CUT-OFF LINE UNDER THE INFLUENCE OF HEAT

This test consists of verifying that the vertical drift of the cut-off line under the influence of heat does not exceed
a specified value for an operating passing lamp.

(1) NaCMC represents the sodium salt of carboxymethylcellulose, customarily referred to as CMC. The NaCMC used in the dirt mixture shall

have a degree of substitution (DS) of 0,6-0,7 and a viscosity of 200-300 cP for a 2 per cent solution at 20 °C.
(2) The tolerance on quantity is due to the necessity of obtaining a dirt that correctly spreads out on all the plastic lens.
(3) Point 50 V is situated 375 mm below HV on the vertical line v-v on the screen at 25 m distance.

Test results

2.2.1.

2.2.2.

The result in milliradians (mrad) shall be considered as acceptable for a passing lamp, only when the absolute
value ΔrI = |r3 – r60| recorded on the headlamp is not more than 1,0 mrad (ΔrI ≤ 1,0 mrad).

However, if this value is more than 1,0 mrad but not more than 1,5 mrad (1,0 mrad < ΔrI ≤ 1,5 mrad) a second
headlamp shall be tested as described in paragraph 2.1. after being subjected three consecutive times to the cycle
as described below, in order to stabilize the position of mechanical parts of the headlamp on a base represen-
tative of the correct installation on the vehicle:

Operation of the passing beam for one hour (the voltage shall be adjusted as specified in paragraph 1.1.1.2),

METHOD OF MEASUREMENT OF THE DIFFUSION AND TRANSMISSION
OF LIGHT

1. EQUIPMENT (see figure)

The beam of a collimator K with a half divergence β/2 = 17,4 × 104 rd is limited by a diaphragm Dτ with an opening of
6 mm against which the sample stand is placed.

A convergent achromatic lens L2, corrected for spherical aberrations links the diaphragm Dτ with the receiver R; the
diameter of the lens L2 shall be such that it does not diaphragm the light diffused by the sample in a cone with a half top
angle of β/2 = 14°.

An annular diaphragm DD, with angles α°/2 = 1° and αmax/2 = 12° is placed in an image focal plane of the lens L2.

The non-transparent central part of the diaphragm is necessary in order to eliminate the light arriving directly from the
light source. It shall be possible to remove the central part of the diaphragm from the light beam in such a manner that
it returns exactly to its original position.

The distance L2 Dτ and the focal length F2 (1) of the lens L2 shall be so chosen that the image of Dτ completely covers the
receiver R.

When the initial incident flux is referred to 1 000 units, the absolute precision of each reading shall be better than 1 unit.

2. MEASUREMENTS

The following readings shall be taken:

SPRAY TESTING METHOD

1.

Test equipment

1.1. Spray gun

The spray gun used shall be equipped with a nozzle 1,3 mm in diameter allowing a liquid flow rate of
0,24 ± 0,02 l/minute at an operating pressure of 6,0 bars – 0, + 0,5 bar.

Under these operation conditions the fan pattern obtained shall be 170 mm ± 50 mm in diameter on the surface
exposed to deterioration, at a distance of 380 mm ± 10 mm from the nozzle.

1.2. Test mixture

The test mixture shall be composed of:

Silica sand of hardness 7 on the Mohr scale, with a grain size between 0 and 0,2 mm and an almost normal distribu-
tion, with an angular factor of 1,8 to 2;

Water of hardness not exceeding 205 g/m3 for a mixture comprising 25 g of sand per litre of water.

2.

Test

The outer surface of the lamp lenses shall be subjected once or more than once to the action of the sand jet produced
as described above. The jet shall be sprayed almost perpendicular to the surface to be tested.

The deterioration shall be checked by means of one or more samples of glass placed as a reference near the lenses to
be tested. The mixture shall be sprayed until the variation in the diffusion of light on the sample or samples measured
by the method described in appendix 2, is such that:

Δd =

T5 – T4
T2

=0,0250 ± 0,0025

Several reference samples may be used to check that the whole surface to be tested has deteriorated homogeneously.

APPENDIX 4

ADHESIVE TAPE ADHERENCE TEST

1. PURPOSE

This method allows to determine under standard conditions the linear force of adhesion of an adhesive tape to a glass
plate.

2. PRINCIPLE

Measurement of the force necessary to unstick an adhesive tape from a glass plate at an angle of 90°.

3. SPECIFIED ATMOSPHERIC CONDITIONS

The ambient conditions shall be at 23 °C ± 5 °C and 65 ± 15 per cent RH.

4. TEST PIECES

Before the test, the sample roll of adhesive tape shall be conditioned for 24 hours in the specified atmosphere (see para.
3 above).

Five test pieces each 400 mm long shall be tested from each roll. These test pieces shall be taken from the roll after the
first three turns were discarded.

5. PROCEDURE

The test shall be under the ambient conditions specified in paragraph 3.

Take the five test pieces while unrolling the tape radially at a speed of approximately 300 mm/s, then apply them within
15 seconds in the following manner:

Apply the tape to the glass plate progressively with a slight length-wise rubbing movement of the finger, without exces-
sive pressure, in such a manner as to leave no air bubble between the tape and the glass plate.

Leave the assembly in the specified atmospheric conditions for 10 minutes.

Unstick about 25 mm of the test piece from the plate in a plane perpendicular to the axis of the test piece.

Fix the plate and fold back the free end of the tape at 90°. Apply force in such a manner that the separation line between
the tape and the plate is perpendicular to this force and perpendicular to the plate.

Pull to unstick at a speed of 300 mm/s ± 30 mm/s and record the force required.

6. RESULTS

The five values obtained shall be arranged in order and the median value taken as a result of the measurement. This value
shall be expressed in Newtons per centimetre of width of the tape.

CHANGE OF THE VERTICAL POSITION OF THE CUT-OFF LINE

With respect to the verification of the change in vertical position of the cut-off line under the influence of heat, the
following procedure shall be applied:

One of the headlamps of sample A after sampling procedure in Figure 1 of this annex shall be tested according to
the procedure described in paragraph 2.1 of annex 4 after being subjected three consecutive times to the cycle
described in paragraph 2.2.2 of annex 4.

The headlamp shall be considered as acceptable if Δr does not exceed 1,5 mrad.

If this value exceeds 1,5 mrad but is not more than 2,0 mrad, the second headlamp of sample A shall be subjected
to the test after which the mean of the absolute values recorded on both samples shall not exceed 1,5 mrad.

However, if this value of 1,5 mrad on sample A is not complied with, the two headlamps of sample B shall be
subjected to the same procedure and the value of Δr for each of them shall not exceed 1,5 mrad.
