4.3.4.   Distributed lighting systems

For distributed lighting systems the applicable provisions of paragraphs 4.3.1 to 4.3.3.2 shall be complied with, in conjunction with the requirements of paragraph 3.4.

B.   TECHNICAL REQUIREMENTS FOR HEADLAMPS (5)

5.   GENERAL SPECIFICATIONS

5.1.   Each sample shall comply with 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 vehicle as to comply with the rules applicable to them. Such a device need not be fitted on units in which the reflector and the diffusing lens cannot be separated, provided the use of such units is confined to vehicles on which the headlamps setting can be adjusted by other means.

Where a headlamp providing a principal passing beam and a headlamp providing a driving beam, each equipped with its own light source(s), are assembled to form a composite unit, the adjusting device shall enable each optical system individually to be duly adjusted. The same provision applies to headlamps providing a front fog lamp beam and a driving beam, and to headlamps providing a principal passing beam and a front fog lamp beam, and to headlamps providing these three beams.

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 shall apply.

5.3.   Headlamps designed to satisfy the requirements of both 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 light source(s) 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 inadvertent shifting from one setting to the other or setting in an intermediate position. Where two different setting positions are provided for the light source, the components for attaching the light source to the reflector must be so designed and made that, in each of its two settings, the light source 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.

5.4.   Illumination configuration for different traffic conditions

5.4.1.   In the case of headlamps designed to meet the requirements of traffic moving on one side of the road (either right or left) only, appropriate measures shall be taken to prevent discomfort to road-users in a country where traffic moves on the side of the road opposite to that of the country for which the headlamp was designed (6). Such measures may be:

(a)

Occulting a part of the outer headlamp lens area;

(b)

Downward movement of the beam. Horizontal movement is allowed;

(c)

Any other measure to remove or reduce the asymmetrical part of the beam.

5.4.2.   Following the application of this (these) measure(s) the following requirements regarding the luminous intensity of the headlamp shall be met with the adjustment left unchanged compared to that for the original traffic direction:

5.4.2.1.

Passing beam designed for right-hand traffic and adapted to left-hand traffic:

 

At 0,86D-1,72L at least 2 500 cd;

 

At 0,57U-3,43R not more than 880 cd.

5.4.2.2.

Passing beam designed for left-hand traffic and adapted to right-hand traffic:

 

At 0,86D-1,72R at least 2 500 cd;

 

At 0,57U-3,43L not more than 880 cd.

5.5.   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 a bend lighting, any mechanical, electro-mechanical or other device incorporated in the headlamp for these purposes (7) must be so constructed that:

5.5.1.

The device is robust enough to withstand 50 000 operations under normal conditions of use. In order to verify compliance with this requirement, the Technical Service responsible for approval tests may:

(a)

Require the applicant to supply the equipment necessary to perform the test;

(b)

Forego the test if the headlamp presented by the applicant is accompanied by a test report, issued by a Technical Service responsible for approval tests for headlamps of the same construction (assembly), confirming compliance with this requirement.

5.5.2.

In the case of failure the luminous intensity of the headlamp above the line H-H shall not exceed the values of a passing beam according to paragraph 6.2.6; in addition, on headlamps designed to provide a passing and/or a driving beam to become a bend lighting, a luminous intensity of at least 2 500 cd shall be fulfilled in test point 25 V (VV line, 1,72 D).

5.5.3.

Either the principal passing beam or the driving beam can always be obtained without any possibility of the mechanism stopping in between the two positions;

5.5.4.

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

5.6.   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.

5.7.   Light transmitting components made of plastic material shall be tested according to the requirements of Annex 5.

5.8.   Replaceability of light sources

5.8.1.   The gas-discharge light source(s) used in gas-discharge headlamps or in distributed lighting systems shall be replaceable and approved according to Regulation No 99 and its series of amendments in force at the time of application for type approval. However, gas-discharge light source(s) not approved according to Regulation No 99 can be used only in the case where they are a non-replaceable part of a light-generator. However, in the case of distributed lighting systems the light-generator can be replaceable without using special tools also in the case where the light-source used in it is not approved.

5.8.2.   In the case that one or more (additional) filament light sources are used in the gas-discharge headlamp, these filament light sources shall be approved according to Regulation No 37 and its series of amendments in force at the time of application for type approval, provided that no restriction on the use is made in Regulation No 37 and its series of amendments in force at the time of application for type approval.

5.8.3.   The design of the device shall be such that the filament lamp, if any, can be fixed in no other position but the correct one.

5.8.4.   In the case of replaceable gas-discharge light sources and in the case of additional filament light sources the lamp holder shall conform to the dimensional characteristics as given on the data sheet of IEC Publication 60061, relevant to the category of light source(s) used. The light source(s) shall fit easily into the headlamp.

5.9.   Non-replaceable gas-discharge light sources not approved under Regulation No 99 used in distributed lighting systems shall moreover comply with the following requirements (corresponding to those specified in Regulation No 99 for approval of gas-discharge light sources):

5.9.1.

Starting, run-up and hot-restrike as prescribed in paragraph 3.6 of Regulation No 99;

5.9.2.

Colour as prescribed in paragraph 3.9 of Regulation No 99. The colour shall be white;

5.9.3.

UV-radiation as prescribed in paragraph 3.10 of Regulation No 99, if so indicated in the application for approval (paragraph 2.2.2 above).

5.10.   The headlamp and ballast system shall not generate radiated or power line disturbances to cause a malfunction of other electric/electronic systems of the vehicle (8).

5.11.   If it is necessary for the test procedure, the test house may require from the manufacturer additional test samples, test benches (holders) or special power supplies.

5.12.   The test procedure shall be carried out under the mounting specifications of the manufacturer.

5.13.   The headlamp (if equipped with LED modules) and the LED module(s) themselves shall comply with the relevant requirements specified in Annex 11 to this Regulation. The compliance with the requirements shall be tested.

6.   ILLUMINATION

6.1.   General provisions

6.1.1.   Headlamps or distributed lighting systems shall be so made that with suitable gas-discharge light source they give adequate illuminance without dazzle when emitting the passing-beam, and good illumination when emitting the driving-beam.

6.1.2.   The luminous intensity produced by the headlamp shall be measured at 25 m distance by means of a photoelectric cell having a useful area comprised within a square of 65 mm side. The point HV is the centre-point of the coordinate system with a vertical polar axis. Line h is the horizontal through HV (see Annex 3 to this Regulation).

6.1.3.   The headlamp or distributed lighting systems shall be deemed satisfactory if the photometric requirements set in the present paragraph 6 are met with one light source, which has been aged during at least 15 cycles, in accordance with Annex 4, paragraph 4 of Regulation No 99.

Where the gas-discharge light source is approved according to Regulation No 99 it shall be a standard (étalon) light-source and its luminous flux may differ from the objective luminous flux specified in Regulation No 99. In this case, the luminous intensities shall be corrected accordingly.

The above correction does not apply to distributed lighting systems using a non-replaceable gas-discharge light source or to headlamps with the ballast(s) totally or partially integrated.

Where the gas-discharge light source is not approved according to Regulation No 99 it shall be a production non-replaceable light source.

6.1.4.   The dimensions determining the position of the arc inside the standard gas-discharge light source are shown in the relevant data sheet of Regulation No 99.

6.1.5.   Photometric compliance must be checked in accordance with paragraph 6.2.6 or 6.3 of this Regulation. This is also valid for the cut-off zone between 3°R and 3°L (measurement method for the cut-off colour being under consideration).

6.1.6.   The colour of the light of the beams emitted by headlamps using gas-discharge light sources shall be white.

6.1.7.   Four seconds after ignition of a headlamp, equipped with a gas discharge light source with the ballast not integrated with the light source, and that has not been operated for 30 minutes or more:

6.1.7.1.

At least 37 500 cd shall be attained at point HV, for a headlamp producing driving beam only.

6.1.7.2.

At least 6 250 cd shall be attained at point 50V for headlamps producing passing beam only or alternately passing and driving beam functions as described in paragraph 5.4 of this Regulation.

6.1.7.3.

In either case the power supply shall be sufficient to secure the required rise of the high current pulse.

6.2.   Provisions concerning passing beams

6.2.1.   The luminous intensity distribution of the passing beam headlamp shall incorporate a ‘cut-off’ (see Figure 1 below), which enables the headlamp to be adjusted correctly for the photometric measurements and for the aiming on the vehicle.

The ‘cut-off’ shall provide:

(a)

For right hand traffic beams:

(i)

A straight ‘horizontal part’ towards the left;

(ii)

A raised ‘elbow — shoulder’ part towards the right.

(b)

For left hand traffic beams:

(i)

A straight ‘horizontal part’ towards the right;

(ii)

A raised ‘elbow — shoulder’ part towards the left.

In each case the ‘elbow — shoulder’ part shall have a sharp edge.

6.2.2.   The headlamp shall be visually aimed by means of the ‘cut-off’ (see Figure 1) as follows. The aiming shall be carried out using a flat vertical screen set up at a distance of 10 m or 25 m (as indicated in section 9 of Annex 1) forward of the headlamp and at right angles to the H-V axis as shown in Annex 3 to this Regulation. The screen shall be sufficiently wide to allow examination and adjustment of the ‘cut-off’ of the passing beam over at least 5° on either side of the V-V line.

6.2.2.1.   For vertical adjustment: the horizontal part of the ‘cut-off’ is moved upward from below line B and adjusted to its nominal position one per cent (0,57 degrees) below the H-H line;

Figure 1

Image

Note: The scales are different for vertical and horizontal lines.

6.2.2.2.   For horizontal adjustment: the ‘elbow — shoulder’ part of the ‘cut-off’ shall be moved:

 

For right hand traffic from right to left and shall be horizontally positioned after its movement so that:

(a)

Above the line 0,2° D its ‘shoulder’ shall not exceed the line A to the left and

(b)

On the line 0,2° D or below its ‘shoulder’ should cross the line A and

(c)

The kink of the ‘elbow’ is basically located within +/– 0,5 degrees to the left or right of the V-V line;

Or

 

For left hand traffic from left to right and shall be horizontally positioned after its movement so that:

(a)

Above the line 0,2° D its ‘shoulder’ shall not exceed the line A to the right and

(b)

On the line 0,2° D or below its ‘shoulder’ should cross the line A and

(c)

The kink of ‘elbow’ should be primarily on the V-V line.

6.2.2.3.   Where a headlamp so aimed does not meet the requirements set out in paragraphs 6.2.5, 6.2.6 and 6.3, its alignment may be changed, provided that the axis of the beam is not displaced:

 

Horizontally from line A by more than:

(a)

0,5° to the left or 0,75° to the right, for right hand traffic or

(b)

0,5° to the right or 0,75° to the left, for left hand traffic and

 

Vertically not more than 0,25° up or down from line B.

6.2.2.4.   If, however, vertical adjustment cannot be performed repeatedly to the required position within the tolerances described in paragraph 6.2.2.3 above, the instrumental method of Annex 10, paragraphs 2 and 3 shall be applied to test compliance with the required minimum quality of the ‘cut-off’ and to perform the vertical and horizontal adjustment of the beam.

6.2.3.   When so aimed, the headlamp needs, if its approval is sought solely for a passing beam, to comply only with the requirements referred to in paragraphs 6.2.4 and 6.2.5 below; if it is intended to provide both a passing beam and a driving beam, it shall comply with the requirements set out in paragraphs 6.2.4 to 6.2.6.

6.2.4.   Only one gas-discharge light source is permitted for each passing beam headlamp. A maximum of two additional light sources are permitted as follows:

6.2.4.1.   One additional light source according to Regulation No 37 or one or more additional LED module(s) may be used inside the passing beam headlamp to contribute to bend lighting.

6.2.4.2.   One additional light source according to Regulation No 37, and/or one or more LED module(s) inside the passing beam headlamp, may be used for the purposes of generating infrared radiation. It/they shall only be activated at the same time as the gas discharge light source. In the event that the gas-discharge light source fails, this additional light source and/or LED module(s) shall be automatically switched off.

6.2.4.3.   In the event of failure of an additional light source or LED module, the headlamp shall continue to fulfil the requirements of the passing beam.

6.2.4.4.   Measurement conditions with respect to light sources

6.2.4.4.1.

In the case of a gas-discharge light source:

The voltage applied to the terminals of the ballast(s) is either 13,2 V +/– 0,1 for 12 V systems or otherwise specified (see Annex 7).

6.2.4.4.2.

In the case of a filament light source according to Regulation No 37:

The lamp shall be measured by means of an uncoloured standard (étalon) filament lamp designed for a rated voltage of 12 V. During the checking, the voltage at the terminals of the filament lamp shall be regulated so as to obtain the reference luminous flux at 13,2 V as indicated at the relevant data sheet of Regulation No 37.

6.2.4.4.3.

In the case of LED module(s):

The lamp shall be measured at 6,3 V, 13,2 V or 28,0 V respectively, if not otherwise specified within this Regulation. LED module(s) operated by an electronic light source control gear, shall be measured as specified by the applicant.

6.2.6.   The requirements in paragraph 6.2.5 above shall also apply to headlamps designed to provide bend lighting and/or that include the additional light source or LED module(s) referred to in paragraph 6.2.4.2. In the case of a headlamp designed to provide bend lighting its alignment may be changed, provided that the axis of the beam is not displaced vertically by more than 0,2°.

6.2.6.1.   If bend lighting is obtained by:

6.2.6.1.1.

Swivelling the passing beam or moving horizontally the kink of the elbow of the cut-off, the measurements shall be carried out after the complete headlamp assembly has been reaimed horizontally, e. g. by means of a goniometer;

6.2.6.1.2.

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 operating position;

6.2.6.1.3.

Means of one additional light source or one or more LED module(s) without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with this light source or LED module(s) 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 luminous intensity of the driving beam shall be taken with the same headlamp alignment as for measurements under paragraph 6.2.5 above; in the case of a headlamp providing a driving beam only, it shall be so adjusted that the area of maximum luminous intensity is centred on the point of intersection of lines H-H and V-V; such a headlamp needs meet only the requirements referred to in paragraph 6.3. Test voltages are the same as in paragraph 6.2.4.4.

6.3.2.   It is possible to use several light sources for the driving beam, these light sources being listed in Regulation No 37 (in this case the filament lamps shall be operated at their reference luminous flux), in Regulation No 99 and/or they can be LED module(s). Where more than one light source is used to provide the driving beam, these light sources shall be operated simultaneously whilst determining the maximum value of luminous intensity (IM).

It is also possible that a part of the driving beam produced by one of these light sources will be used exclusively for short time signals (flash to pass) as declared by the applicant. This shall be indicated in the relevant drawing and a remark shall be made in the communication form.

6.3.3.   Referring to Annex 3, Figure C, and the table below, the luminous intensity distribution of the driving beam shall meet the following requirements.

6.3.3.2.   The maximum value (IM) shall in no circumstances exceed 215 000 cd.

6.3.4.   The reference mark (I’M) of the maximum luminous intensity, referred to in paragraph 6.3.3.2 above, shall be obtained by the ratio:

I’M = IM/4 300.

This value shall be rounded off to the value 7,5 — 10 — 12,5 — 17,5 — 20 — 25 — 27,5 — 30 — 37,5 — 40 — 45 — 50.

6.4.   Provisions concerning movable reflectors

6.4.1.   With the lamp fixed according to all the positions described in paragraph 2.1.4, the headlamp must meet the photometric requirements of paragraph 6.2 or 6.3, or both.

6.4.2.   Additional tests are made after the reflector has been tilted vertically upwards by the angle quoted in paragraph 2.1.4 or 2 degrees, whichever is smaller, by means of the headlamp aiming devices. The headlamp is then re-aimed downwards (by means of the goniometer), and the photometric specifications must be met at the following points:

Principal passing beam

:

HV and 75 R (75 L respectively);

Driving beam

:

IM and point HV (percentage of IM).

If the aiming devices do not allow a continuous movement, the position nearest to 2 degrees is chosen.

6.4.3.   The reflector is brought back to its nominal angular position as defined in paragraph 6.2.2, and the goniometer is set back to its position of origin. The reflector is tilted vertically downwards by the angle quoted in paragraph 2.1.4, or 2 degrees, whichever is smaller, by means of the headlamp aiming device. The headlamp is then re-aimed upwards (by means of the goniometer for example) and points as in paragraph 6.5.2 are checked.

7.   GAUGING OF DISCOMFORT AND/OR DISABILITY

The discomfort and/or disability caused by the passing beam of headlamps shall be gauged (11).

Once the photometric values have been measured according to the prescriptions of this Regulation, in the point for Imax for driving beam and in points HV, 50 R and B 50 L for passing beam (or HV, 50 L, B 50 R for headlamps designed for left-hand traffic) a complete headlamp sample shall be tested for stability of photometric performance in operation. ‘Complete headlamp’ shall be understood to mean the complete lamp itself including ballast(s) and those surrounding body parts and lamps which could influence its thermal dissipation.

The tests shall be carried out:

(a)

In a dry and still atmosphere at an ambient temperature of 23 °C ± 5 °C, the test sample being mounted on a base representing the correct installation on the vehicle;

(b)

In case of replaceable light sources: using mass production filament light sources, which have been aged for at least one hour, or mass production gas-discharge light sources, which have been aged for at least 15 hours or mass production LED modules which have been aged for at least 48 hours and cooled down to ambient temperature before starting the tests as specified in this Regulation. The LED modules supplied by the applicant shall be used.

The measuring equipment shall be equivalent to that used during headlamp type approval tests.

The test sample shall be operated without being dismounted from or readjusted in relation to its test fixture. The light source used shall be a light source of the category specified for that headlamp.

1.   TEST FOR STABILITY OF PHOTOMETRIC PERFORMANCE

The tests shall be carried out in a dry and still atmosphere at an ambient temperature of 23 ± 5 °C, the complete headlamp being mounted on a base representing the correct installation on the vehicle.

1.1.   Clean headlamp

The headlamp shall be operated for 12 hours as described in subparagraph 1.1.1 and checked as prescribed in subparagraph 1.1.2.

1.1.1.   Test procedure

The headlamp shall be operated for a period according to the specified time, so that:

(a)

In the case where only one lighting function (driving or passing beam)is to be approved, the corresponding light source is lit for the prescribed time (1);

(b)

In the case of a reciprocally incorporated passing beam lamp and driving beam lamp or in the case of a reciprocally incorporated front fog lamp and driving beam headlamp:

 

If the applicant declares that the headlamp is to be used with a single light source lit (2) at a time, the test shall be carried out in accordance with this condition, activating (1) each specified function successively for half the time specified in paragraph 1.1,

 

In all other cases (1), (2), the headlamp shall be subjected to the following cycle until the time specified is reached:

 

15 minutes, passing beam lit;

 

5 minutes, all functions lit;

 

In the case of a passing beam and a driving beam provided by the same gas-discharge light source, the cycle will be:

 

15 minutes, passing beam lit;

 

5 minutes, all driving beam contributors lit.

(c)

In the case of grouped lighting functions, all the individual functions shall be lit simultaneously for the time specified for individual lighting functions (a), also taking into account the use of reciprocally incorporated lighting functions (b), according to the manufacturer’s specifications.

(d)

In the case of a passing beam designed to provide bend lighting with the addition of a light source, this light source shall be switched on for 1 minute, and switched off for 9 minutes during the activation of the passing beam only (see the Appendix of this Annex).

(e)

In the case that the driving beam uses several light sources in accordance with paragraph 6.3.2 and if the applicant declares that a part of the driving beam (one of these additional light sources) will be used exclusively for short time signals (flash to pass), the test shall be carried out without this part of the driving beam.

1.1.1.2.   Test voltage

The voltage shall be applied to the terminals of the test sample as follows:

(a)

In case of replaceable filament light source(s) operated directly under vehicle voltage system conditions: the test shall be performed at 6,3 V, 13,2 V or 28,0 V as applicable except if the applicant specifies that the test sample may be used at a different voltage. In this case, the test shall be carried out with the filament light source operated at the highest voltage that can be used.

(b)

In case of replaceable gas discharge light source(s): The test voltage for the electronic light source control-gear is 13,2 ± 0,1 volts for 12 V vehicle voltage system, or otherwise specified in the application for approval.

(c)

In the case of non-replaceable light source operated directly under vehicle voltage system conditions: All measurements on lighting units equipped with non-replaceable light sources (filament light sources and/or others) shall be made at 6,3 V, 13,2 V or 28,0 V or at other voltages according to the vehicle voltage system as specified by the applicant respectively.

(d)

In the case of light sources, replaceable or non-replaceable, being operated independently from vehicle supply voltage and fully controlled by the system, or, in the case of light sources supplied by a supply and operating device, the test voltages as specified above shall be applied to the input terminals of that device. The test laboratory may require from the manufacturer the supply and operating device or a special power supply needed to supply the light source(s).

(e)

LED module(s) shall be measured at 6,75 V, 13,2 V or 28,0 V respectively, if not otherwise specified within this Regulation. LED module(s) operated by an electronic light source control gear shall be measured as specified by the applicant.

(f)

Where signalling lamps are grouped, combined or reciprocally incorporated into the test sample and operating at voltages other than the nominal rated voltages of 6 V, 12 V or 24 V respectively, the voltage shall be adjusted as declared by the manufacturer for the correct photometric functioning of that lamp.

1.1.2.   Test results

1.1.2.1.   Visual inspection:

Once the headlamp has been stabilized to the ambient temperature, the headlamp lens and the external lens, if any, shall be cleaned with a clean, damp cotton cloth. It shall then be inspected visually; no distortion, deformation, cracking or change in colour of either the headlamp lens or the external lens, if any, shall be noticeable.

1.1.2.2.   Photometric test:

To comply with the requirements of this Regulation, the photometric values shall be verified in the following points:

 

Passing beam:

 

50 R — B 50 L — 25 L for headlamps designed for right-hand traffic

 

50 L — B 50 R — 25 R for headlamps designed for left-hand traffic

 

Driving beam: Point Imax.

Another aiming may be carried out to allow for any deformation of the headlamp base due to heat (the change of the position of the cut-off line is covered in paragraph 2 of this Annex).

Except for point B50L, a 10 per cent discrepancy between the photometric characteristics and the values measured prior to the test is permissible including the tolerances of the photometric procedure. The value measured at point B50L shall not exceed the photometric value measured prior to the test by more than 170 cd.

1.2.   Dirty headlamp

After being tested as specified in subparagraph 1.1 above, the headlamp shall be operated for one hour as described in subparagraph 1.1.1, after being prepared as prescribed in subparagraph 1.2.1, and checked as prescribed in subparagraph 1.1.2.

50 L and 50 V (5) for a headlamp producing only a passing beam, designed for left-hand traffic.

2.   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 headlamp producing a passing beam.

The headlamp tested in accordance with paragraph 1 shall be subjected to the test described in paragraph 2.1, without being removed from or readjusted in relation to its test fixture.

If the headlamp has a moving reflector, only the position closest to the average vertical angular stroke is chosen for this test.

2.1.   Test for passing beam headlamps

The test shall be carried out in a dry and still atmosphere at an ambient temperature of 23 ± 5 °C.

Using a mass production gas-discharge light source which has been aged for at least 15 hours, the headlamp shall be operated on passing beam function without being dismounted from or readjusted in relation to its test fixture. (For the purpose of this test, the voltage shall be adjusted as specified in paragraph 1.1.1.2). The position of the cut-off line in its horizontal part (between VV and the vertical line passing through point B 50 L for right-hand traffic or B 50 R for left-hand traffic) shall be verified 3 minutes (r3) and 60 minutes (r60) respectively after operation.

The measurement of the variation in the cut-off line position as described above shall be carried out by any method giving acceptable accuracy and reproducible results.

2.2.   Test results

2.2.1.

The result expressed in milliradians (mrad) shall be considered as acceptable for a passing beam headlamp when the absolute value

Formula

recorded on the headlamp is not more than 1,0 mrad (Δ r1 ≤ 1,0 mrad) upward and not more than 2,0 mrad (Δ r1 ≤ 2,0 mrad) downwards.

2.2.2.

However, if this value is:

Movement

 

Upward

more than 1,0 mrad but not more than 1,5 mrad

(1,0 mrad < ΔrI ≤ 1,5 mrad)

Downward

more than 2,0 mrad but not more than 3,0 mrad

(2,0 mrad < ΔrI ≤ 3,0 mrad)

A further sample of a 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 representative 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),

 

After this period of one hour, the headlamp type shall be considered as acceptable if the absolute value Δr measured on this sample meets the requirements in paragraph 2.2.1 above.


(1)  When the tested headlamp is grouped and/or reciprocally incorporated with signalling lamps, the latter shall be lit for the duration of the test. In the case of a direction indicator lamp, it shall be lit in flashing operation mode with an on/off time ratio of approximately one to one.

(2)  Should two or more light sources be simultaneously lit when headlamp flashing is used, this shall not be considered as being normal use of the light sources simultaneously.

(3)  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.

(4)  The tolerance on quantity is due to the necessity of obtaining a dirt that correctly spreads out on all the plastic lens.

(5)  50 V is situated 375 mm below HV on the vertical line VV on the screen at 25 m distance.
