ANNEX 4

TESTS FOR STABILITY OF PHOTOMETRIC PERFORMANCE OF SYSTEMS IN OPERATION — TESTS ON COMPLETE SYSTEMS

Tests on complete systems

Once the photometric values have been measured according to the prescriptions of this Regulation, in the point of Imax for driving beam and in points 25L, 50V and B50L (or R), whichever applies for passing beam, a complete system sample shall be tested for stability of photometric performance in operation.

For the purpose of this annex:

(a)

‘Complete system’ shall be understood to mean the complete right and left side of a system itself including electronic light source control-gear(s) and/or supply and operating device(s) and those surrounding body parts and lamps which could influence its thermal dissipation. Each installation unit of the system and lamp(s) and/or LED module, if any, of the complete system may be tested separately;

(b)

‘Test sample’ in the following text means correspondingly either the ‘complete system’ or the installation unit under test;

(c)

The expression ‘light source’ shall be understood to comprise also any single filament of a filament lamp, LED modules or light emitting parts of a LED module.

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 a mass production filament light source, which has been aged for at least one hour, or a mass production gas-discharge light source, which has been aged for at least 15 hours or a mass production LED module which has 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;

(c)

In the case of a system providing an adaptation of the driving-beam, the driving-beam shall be in the maximum condition if activated.

The measuring equipment shall be equivalent to that used during type approval tests of the test samples of the system. The system or part(s) thereof shall, prior to the subsequent tests, be set to the neutral state.

The test sample shall be operated on passing-beam 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

1.1.   Clean test sample

Each test sample shall be operated for 12 hours as described in paragraph 1.1.1 and checked as prescribed in paragraph 1.1.2 below.

1.1.1.   Test procedure

1.1.1.1.   Test sequence

(a)

In the case where a test sample is designed to provide only one lighting function (driving-beam or passing-beam) and not more than one class in case of passing-beam, the corresponding light source(s) is/are lit for the time (1) specified in paragraph 1.1 above;

(b)

In the case where a test sample provides more than one function or class of passing-beam according to this Regulation: if the applicant declares that each specified function or class of passing-beam of the test sample has its own light source(s), being exclusively lit (2) at a time, the test shall be carried out in accordance with this condition, activating (1) the most power consuming mode of each specified function or class of passing-beam successively for the same (equally divided) part of the time specified in paragraph 1.1 above.

In all other cases (1) (2), the test sample shall be subjected to the following cycle test for each, the mode(s) of Class C passing-beam, the Class V passing-beam, the Class E passing-beam and the Class W passing-beam, whatever is provided or partly provided by the test sample, for the same (equally divided) part of the time specified in paragraph 1.1:

15 minutes, first, e.g. Class C passing-beam mode lit with its most power-consuming mode for straight road conditions;

5 minutes, same passing-beam mode lit as before and, additionally, all light sources (3) of the test sample, which are possible to be lit at the same time, according to the applicant's declaration;

After having reached the said (equally divided) part of the time specified in paragraph 1.1 above, the above cycle test shall be performed with the second, third and fourth class of passing-beam, if applicable, in the above order;

(c)

In the case where a test sample includes other grouped lighting function(s), all the individual functions shall be lit simultaneously for the time specified in (a) or (b) above for individual lighting functions, according to the manufacturer's specifications;

(d)

In the case of a test sample designed to provide a passing-beam bending mode or a mode or function which is activated for a short time with an additional light source being energized, said light source shall simultaneously be switched on for 1 minute, and switched off for 9 minutes during the activation of the passing-beam only, specified in (a) or (b) above.

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 6,3 V, 13,2 V or 28 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 test sample has been stabilized to the ambient temperature, the test sample 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 test sample 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:

 

Class C passing-beam, and each specified other passing-beam class: 50V, B50L, and 25RR, if applicable.

 

Driving-beam, under neutral state conditions: point of Imax.

 

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

 

Except for points 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 test sample

After being tested as specified in paragraph 1.1 above, the test sample shall be operated for one hour as described in paragraph 1.1.1 for each function or class of passing-beam (4), after being prepared as prescribed in paragraph 1.2.1, and checked as prescribed in paragraph 1.1.2; after each test a sufficient cooling down period must be assured.

1.2.1.3.   The mixture must not be more than 14 days old.

1.2.1.4.   Application of the test mixture to the test sample

The test mixture shall be uniformly applied to the entire light-emitting surface(s) of the test sample and then left to dry. This procedure shall be repeated until the illuminating value has dropped to 15-20 per cent of the values measured for each following point under the conditions described in this annex:

 

Point Imax in driving beam, under neutral state conditions;

 

50V for a class C passing beam, and each specified passing beam mode.

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 a system or part(s) of emitting a Class C (basic) passing-beam, or each specified passing-beam mode.

If the test sample consists of more than one lighting unit or more than one assembly of lighting units which provide a cut-off, each of these is understood to be a test sample for the purpose of this test and must be tested separately.

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

If the test sample has a moving optical part, only the position closest to the average vertical angular stroke and/or the initial position according to the neutral state is chosen for this test.

The test is confined to signal input conditions corresponding to a straight road, only.

2.1.   Test

For the purpose of this test, the voltage shall be adjusted as specified in paragraph 1.1.1.2 above.

The test sample shall be operated and tested on Class C passing-beam, Class V passing-beam, Class E passing-beam and Class W passing-beam, whatever applies.

The position of the cut-off line in its horizontal part between VV and the vertical line passing through point B50L (or R) 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 Δ r1 = | r3 – r60 | 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 mounted on a test fixture representative of the correct installation on the vehicle 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:

(a)

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

(b)

One hour period with the lamp switched off.

After these three cycles, the headlamp type shall be considered as acceptable if the absolute values Δr measured according to paragraph 2.1 above on this further sample meet the requirements in paragraph 2.2.1 above.


(1)  When the ‘test sample’ is grouped and/or reciprocally incorporated with signalling lamps, the latter shall be lit for the duration of the test, except for a daytime running lamp. 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 additional 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)  All light sources of lighting functions even if no approval is sought according to this Regulation must be taken into account, except those covered by footnote 2.

(4)  The Class W passing-beam, if any, is disregarded for lighting units providing or contributing to any other passing-beam class or lighting function.

(5)  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.

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

2.2.2.2.   Application of the test mixture

Soak a piece of cotton cloth (as per ISO 105) until saturation with the mixture defined in paragraph 2.2.2.1 above and, within 10 seconds, apply it for 10 minutes to the outer face of the sample at a pressure of 50 N/cm2, corresponding to an effort of 100 N applied on a test surface of 14 × 14 mm.

During this 10-minute period, the cloth pad shall be soaked again with the mixture so that the composition of the liquid applied is continuously identical with that of the test mixture prescribed.

During the period of application, it is permissible to compensate the pressure applied to the sample in order to prevent it from causing cracks.

METHOD OF MEASUREMENT OF THE DIFFUSION AND TRANSMISSION OF LIGHT

1.   EQUIPMENT (see Figure 1 below)

The beam of a collimator K with a half divergence β/2 = 17,4 × 10 – 4 rad 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 degrees.

An annular diaphragm DD, with angles αo/2 = 1 deg and αmax/2 = 12 degrees 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 of the lens L2 shall be so chosen that the image of Dτ completely covers the receiver R.

For L2 it is recommended to use a focal distance of about 80 mm.

When the initial incident flux is referred to 1 the absolute precision of each reading shall be better than 0,001.

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 degrees.

3.   SPECIFIED ATMOSPHERIC CONDITIONS

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

4.   TEST PIECES

Before the test, the sample roll of adhesive tape shall be conditioned for 24 hours in the specified atmosphere (see paragraph 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 performed under the ambient conditions specified in paragraph 3 above.

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 excessive 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 degrees. 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 Newton per centimetre of width of the tape.

ANNEX 8

PASSING-BEAM ‘CUT-OFF’ AND AIMING PROVISIONS

1.   CUT-OFF DEFINITION

The ‘cut-off’, when projected on the aiming screen shall be sufficiently sharp to permit aiming; it shall comply with the following requirements.

1.1.   Shape (see Figure 1)

The ‘cut-off’ shall provide:

(a)

A straight ‘horizontal part’ towards the left;

(b)

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

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

2.   VISUAL AIMING PROCEDURE

Horizontally, from line A by more than: 0,5° to the left or 0,75° to the right;

 

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

2.6.   If, however, vertical adjustment cannot be performed repeatedly to the required position within the tolerances described in paragraph 2.5 above, the instrumental method described in paragraph 3 below shall be applied to test compliance with the required minimum quality of the ‘cut-off’ (as defined in paragraph 2.7 below) and to perform the vertical and horizontal adjustment of the beam.

2.7.   Measurement of the quality of the ‘cut-off’

To determine the minimum sharpness, measurements shall be performed by vertically scanning through the horizontal part of the ‘cut-off’ in angular steps of 0,05° at either a measurement distance of:

(a)

10 m with a detector having a diameter of approximately 10 mm or

(b)

To determine the maximum sharpness, measurements shall be performed by vertically scanning through the horizontal part of the ‘cut-off’ in angular steps of 0,05° exclusively at a measurement distance of 25 m and with a detector having a diameter of approximately 30 mm.

The ‘cut-off’ quality shall be considered acceptable if the requirements of paragraph 2.1 to 2.3 above comply with at least one set of measurements.

2.7.1.   Not more than one ‘cut-off’ shall be visible (1).

2.7.2.   Sharpness of ‘cut-off’

The sharpness factor G is determined by scanning vertically through the horizontal part of the ‘cut-off’ at 2,5° from the V-V where:

 

G = (log Εβ - log E(β + 0,1°)) where β = the vertical position in degrees.

 

The value of G shall not be less than 0,13 (minimum sharpness) and not greater than 0,40 (maximum sharpness).

2.7.3.   Linearity

The part of the horizontal ‘cut-off’ that serves for vertical adjustment shall be horizontal between 1,5° and 3,5° from the V-V line (see Figure 1a of paragraph 3 below):

(a)

The inflection points of the ‘cut-off’ gradient at the vertical lines at 1,5°, 2,5° and 3,5° shall be determined by the equation:

(d2 (log E)/dβ2 = 0).

(b)

The maximum vertical distance between the inflection points determined shall not exceed 0,2°.

2.8.   If a partial beam provides a horizontal ‘cut-off’ only: no special requirements for horizontal adjustment apply if not specified by the applicant.

2.9.   Any ‘cut-off’ of a lighting unit not designed to be separately aimed, according to the applicants specification, must comply with the relevant requirements.

Lines for vertical scan

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

3.1.   Vertical adjustment

Moving upward from below the line B (see Figure 2 below), a vertical scan is carried out through the horizontal part of the ‘cut-off’ at 2,5° from V-V. The inflection point (where d2 (log E)/dv2 = 0) is determined and positioned on the line B situated one per cent below H-H.

3.2.   Horizontal adjustment

The applicant shall specify one of the following horizontal aim methods:

(a)

The ‘0,2 D line’ method (see Figure 2 below).

A single horizontal line at 0,2° D shall be scanned from 5° left to 5° right after the lamp has been aimed vertically. The maximum gradient ‘G’ determined using the formula G = (log Εβ – log E(β + 0,1°)) where β is the horizontal position in degrees, shall not be less than 0,08.

The inflection point found on the 0,2 D line shall be positioned on the line A.

4.3.   Temperature stability

4.3.1.   Illuminance

4.3.1.1.   For each existing class of passing-beam and for the driving-beam, a photometric measurement shall be carried out after one minute of operation of the respective lighting units and for the following test points:

Passing-beam

:

25 RR

Driving-beam

:

HV

4.3.1.2.   Operation of the lighting units mentioned in paragraph 4.3.1.1 above shall then be continued until photometric stability has occurred; this condition is considered to be fulfilled if the variation of the illuminance for the test points indicated in paragraph 4.3.1.1 above is less than 3 per cent within any 15 minutes period. After photometric stability has occurred, aiming for complete photometry shall be performed and the photometric values at all required test points shall be determined.

4.3.1.3.   The ratio between the photometric values measured after one minute of operation and those measured after photometric stability has occurred shall be calculated for the test points indicated in paragraph 4.3.1.1 above. This ratio shall then be applied to all other applicable test points to determine their photometric values after one minute of operation.

4.3.1.4.   The illuminance values determined after one minute of operation and after occurrence of photometric stability shall comply with applicable photometric requirements.

4.3.2.   Colour

The colour of the light emitted measured after one minute and measured after photometric stability has been obtained, as described in paragraph 4.3.1.2 of this annex, shall both be within the required colour boundaries.

5.   THE MEASUREMENT OF THE OBJECTIVE LUMINOUS FLUX OF LED MODULE(S) PRODUCING THE CLASS C (BASIC) PASSING-BEAM SHALL BE CARRIED OUT AS FOLLOWS:

5.1.

The LED module(s) shall be in the configuration as described in the technical specification as defined in paragraph 2.2.2 of this Regulation. Optical elements (secondary optics) shall be removed by the Technical Service at the request of the applicant by the use of tools. This procedure and the conditions during the measurements as described below shall be described in the test report.

5.2.

One module of each type shall be submitted by the applicant with the light source control gear, if applicable, and sufficient instructions.

Suitable thermal management (e.g. heat sink) may be provided, to simulate similar thermal conditions as in the corresponding headlamp application.

Before the test the LED module shall be aged at least for seventy-two hours under the same conditions as in the corresponding headlamp application.

In the case of use of an integrating sphere, the sphere shall have a minimum diameter of one meter, and at least ten times the maximum dimension of the LED module, whichever is the largest. The flux measurements can also be performed by integration using a goniophotometer. The prescriptions in CIE – Publication 84 – 1989, regarding the room temperature, positioning, etc., shall be taken into consideration.

The LED module shall be burned in for approximately one hour in the closed sphere or goniophotometer.

The flux shall be measured after stability has occurred, as explained in paragraph 4.3.1.2 of this annex.
