1. SCOPE

This Regulation applies to the approval of headlamps using filament lamps, producing one single passing beam, which are provided for the equipment of mopeds(1) and vehicles treated as such.

2. DEFINITION OF ‘TYPE’

Headlamps of different ‘types’ means headlamps which differ in such essential respects as:

2.1.

the trade name or mark;

2.2.

the characteristics of the optical system;

2.3.

the inclusion or the suppression of components capable of altering the optical effects by reflexion, refraction or absorption. A change in the colour of the beams emitted by headlamps whose other characteristics are not changed does not constitute a change of headlamp type. The same approval number shall accordingly be assigned to such headlamps.

3. APPLICATION FOR APPROVAL

The application for approval shall be submitted by the holder of the trade name or mark or by his duly accredited representative. Any application shall be accompanied by:

3.1.

Drawings in triplicate, sufficiently detailed to permit identification of the type. The drawings must show the provided position for the approval mark and indicate the headlamp in front and in cross lateral elevation, with schematic indication of the optical grooves and prisms of the lens;

3.2.

A brief technical description stating, in particular, the class of the filament lamp provided;

3.3.

Two devices with colourless lenses(2).

3.4.

The competent authority shall verify the existence of satisfactory arrangements for ensuring effective control of the conformity of production before type approval is granted.

4. MARKINGS

4.1.

Headlamps submitted for approval shall clearly, legibly and indelibly bear the following inscriptions:

4.1.1.

the trade name or mark of the applicant;

4.1.2.

the identification of the category of the provided filament lamp;

4.2.

Moreover, they shall include on the lens and on the main body (the reflector being considered as main body)(3) a space of sufficient size to accommodate the approval marking; these spaces must be shown on the drawings referred to in paragraph 3.1. above.

5. APPROVAL

5.1.

If the devices submitted in accordance with paragraph 3. above meet the requirements of this Regulation, approval shall be granted.

5.2.

An approval number shall be assigned to each type approved. Its first two digits (at present 00 for the Regulation in its original form) shall indicate the series of amendments incorporating the most recent major technical amendment made to the Regulation at the time of issue of the approval. The same Contracting Party may not assign the same number to another type of headlamp.

5.3.

Notice of approval or of extension or refusal of approval of a type of headlamp pursuant to this Regulation shall be communicated to the Parties to the 1958 Agreement which apply this Regulation, by means of a form conforming to the model in annex 1 to this Regulation.

5.4.

Every headlamp conforming to a type approved under this Regulation shall bear in the spaces referred to in paragraph 4.2. above, in addition to the marking prescribed in paragraph 4.1.

5.4.1.

an international approval mark(4) consisting of:

5.4.1.1.

a circle surrounding the letter ‘E’ followed by the distinguishing number of the country which has granted approval(5);

5.4.1.2.

an approval number.

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 device shall conform to the specifications of paragraph 7 of this Regulation.

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.

6.3.

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.

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 with a smooth and colourless bulb according to category S3 of Regulation No 37 shall be used.

The standard filament lamp shall be adjusted to the applicable reference luminous flux according to values prescribed for these lamps in Regulation No 37.

7.3.

The beam shall have a cut-off sufficiently sharp in order that satisfactory aiming can practically be achieved with its aid. The cut-off shall be substantially horizontal and as straight as possible over a horizontal length of at least ± 900 mm measured at a distance of 10 m.

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 on the screen mentioned in paragraph 7.2. above shall be measured by means of a photo-receptor 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 lights with an uncoloured 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 green	y ≤	1,29 x – 0,1
Limit towards white	y ≤	– x + 0,966
Limit towards spectral value	y ≤	– x + 0,992

which can also be expressed as follows:

dominant wave-length	575 - 585 nm
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 2,854 °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. CONFORMITY OF PRODUCTION

9.1.

Headlamps approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraphs 7 and 8.

9.2.

In order to verify that the requirements of paragraph 9.1 are met, suitable controls of the production shall be carried out.

9.4.1.

In every inspection, the test books and production survey records shall be presented to the visiting inspector.

9.4.2.

The inspector may take samples at random to be tested in the manufacturer's laboratory. The minimum number of samples may be determined in the light of the results of the manufacturer's own checks.

9.4.3.

When the quality level appears unsatisfactory or when it seems necessary to verify the validity of the tests carried out in the application of paragraph 9.4.2 above, the inspector shall select samples, to be sent to the technical service which has conducted the type approval tests, using the criteria of annex 5.

9.4.4.

The competent authority may carry out any test prescribed in this Regulation. These tests will be on samples selected at random without causing distortion of the manufacturer's delivery commitments and in accordance with the criteria of annex 5.

9.4.5.

The competent authority shall strive to obtain a frequency of inspection of once every two years. However, this is at the discretion of the competent authority and their confidence in the arrangements for ensuring effective control of the conformity of production. In the case where negative results are recorded, the competent authority shall ensure that all necessary steps are taken to re-establish the conformity of production as rapidly as possible.

9.5.
