5.5 The markings according to paragraph 5.4 shall be clearly legible and indelible.

5.6 Annex 2 to this Regulation gives an example of the arrangement of the approval mark.

6. GENERAL SPECIFICATIONS

6.1 Each sample of a type of headlamp shall conform to the specifications set forth in this paragraph and in paragraph 7 below and, if necessary, to those set forth in paragraph 8.

6.2 Headlamps shall be so designed and constructed that, in normal use, despite the vibrations to which they may be subjected, their satisfactory operation continues to be ensured and they retain the characteristics prescribed by this Regulation.

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

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

6.2.2 However, these provisions shall not apply to headlamp assemblies whose reflectors are indivisible. For this type of assembly the requirements of paragraph 7.3 of the present Regulation shall apply. Where more than one light source is used to provide the main beam, the combined functions shall be used to determine the maximum value of the illumination (Emax).

6.3 The parts intended for holding the filament lamp in the reflector shall be so made that, even in darkness, the filament lamp can be mounted in no other position than the correct one.

6.4 Complementary tests shall be done according to the requirements of annex 5 to ensure that in use there is no excessive change in photometric performance.

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

7. SPECIAL SPECIFICATIONS

7.1 The correct position of the lens in relation to the optical system shall be unequivocally marked and be locked against rotation in service.

7.2 For the measurement of the illumination produced by the headlamp, a measuring screen as described in annex 3 of this Regulation and a standard filament lamp (S1 and/or S2, Regulation No. 37) with a smooth and colourless bulb shall be used.

The standard filament lamp shall be adjusted to the applicable reference luminous flux according to values prescribed for these lamps.

7.3 The passing beam shall have a cut-off sufficiently sharp in order that satisfactory aiming can practically be achieved with its aid. The "cut-off" must be as straight and horizontal as possible over a range of at least 5 degrees on either side of the line v-v (see annex 3). When aimed according to annex 3, the headlamps shall meet the requirements specified in it.

7.4 The beam pattern shall not present any lateral variations detrimental to good visibility.

7.5 The illumination of the screen mentioned in paragraph 7.2 shall be measured by means of a photoelement having a useful area comprised within a square of 65 mm side.

8. PROVISIONS CONCERNING COLOURED LENSES AND FILTERS

8.1 Approval may be obtained for headlamps emitting either colourless or selective yellow light with an uncoloured filament lamp. Expressed in CIE trichromatic co-ordinates, the corresponding colorimetric characteristics for yellow glasses or filters are as follows: Selective-yellow filter (screen or lens)

Limit towards red y> 0.138 + 0.58 x

Limit towards greed y< 1.29 x -0.1

Limit towards white y< -x + 0.966

Limit towards special value y< -x + 0.992

which can also be expressed as follows:

dominant wave-length 575 - 585 n m

purity factor 0.90 - 0.98

The transmission factor must be > 0.78

The transmission factor shall be determined by using a light source with a colour temperature of 2,856 K. (Corresponding to illuminant A of the International Commission on Illumination (CIE)).

8.2 The filter must be part of the headlamp, and must be attached to it in such a way that the user cannot remove it either inadvertently or intentionally, with ordinary tools.

8.3 Observation concerning colour

Since any approval under this Regulation is granted, pursuant to paragraph 8.1 above, for a type of headlamp emitting either colourless light or selective-yellow light; article 3 of the agreement to which the Regulation is annexed shall not prevent the Contracting Parties from prohibiting headlamps emitting a beam of uncoloured or selective yellow light on vehicles registered by them.

9. TRANSITIONAL PROVISIONS

9.1 As from the date of entry into force of the 01 series of amendments to this Regulation no Contracting Party applying it shall refuse to grant approvals under this Regulation as amended by the 01 series of amendments.

9.2 As from 24 months after the date of entry into force mentioned in paragraph 9.1 above, Contracting Parties applying this Regulation shall grant approval only if the type of headlamp corresponds to the requirements of this Regulation as amended by the 01 series of amendments.

9.3 Existing MB-approvals granted under this Regulation before the date mentioned in paragraph 9.2 above shall remain valid.

However, Contracting Parties applying this Regulation may prohibit the fitting of devices which do not meet the requirements of this Regulation as amended by the 01 series of amendments.

9.3.1 On vehicles for which type approval or individual approval is granted more than 24 months after the date of entry into force mentioned in paragraph 9.1 above.

1.2.1.3 Measuring equipment

The measuring equipment shall be equivalent to that used during headlamp approval tests. A standard (reference) filament lamp shall be used for the photometric verification.

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 passing lamp.

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

2.1 Test

The test shall be carried out in a dry and still atmosphere at an ambient temperature of 23 degrees C +/-5 degrees C.

Using a mass production filament lamp which has been aged for at least one hour the headlamp shall be operated on passing beam 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 the vertical lines passing through point 50 L and 50R) 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 in milliradians (mrad) shall be considered as acceptable for a passing lamp, only when the absolute value deltarI = (r3 - r60) recorded on the headlamp is not more than 1.0 mrad (deltarI < 1.0 mrad).

2.2.2 However, if this value is more than 1.0 mrad but not more than 1.5 mrad

(1.0 mrad < deltarI < 1.5 mrad) a second headlamp shall be tested as described in 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:

1.1 The conformity requirements shall be considered satisfied from a mechanical and geometric standpoint, if the differences do not exceed inevitable manufacturing deviations within the requirements of this Regulation.

1.2 With respect to photometric performances, the conformity of mass-produced headlamps shall not be contested if, when testing photometric performances of any headlamp chosen at random and equipped with a standard filament lamp:

1.2.1 no measured value deviates unfavourably by more than 20 % from the values prescribed in this Regulation. For value in zone III, the maximum unfavourable deviation may be respectively:

0.3 lux equivalent 20 %

0.45 lux equivalent 30 %

1.2.2 and if for the driving beam, HV being situated within the isolux 0.75 Emax,

a tolerance of + 20 % for maximum values and - 20 % for minimum values is observed for the photometric values at any measuring point specified in Annex 3, paragraphs 4.3 and 4.4 of this Regulation.

1.2.3 If the results of the tests described above do not meet the requirements, tests on the headlamp shall be repeated, using another standard filament lamp.

1.3 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 sampled headlamps 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 delta r does not exceed 1.5 mrad.
