INTRODUCTION

This Regulation (1) applies to front fog lamps, which may incorporate lenses of glass or plastic material. It incorporates two distinct classes.

The original front fog lamp, class ‘B’ since inception, has been updated to incorporate the angular coordinate system with an amendment to the values in the relevant photometric table. With this class, only light sources as specified in Regulation No 37 are allowed.

The class ‘F3’ is designed to increase photometric performance. In particular the beam width and the minimum luminous intensities below the H-H line (paragraph 6.4.3) have been increased whilst controls on the maximum intensity in the foreground are introduced. Above the H-H line, the intensity of the veiling light is reduced to improve visibility. Additionally this class may provide adaptive beam patterns where the performance is varied according to the visibility conditions.

The introduction of the class ‘F3’ provides for requirements that are amended to be similar to those of a headlamp as follows:

(a)	The photometric values are specified as luminous intensities using the angular coordinate system.

(b)	Light sources can be selected according to the provisions of Regulation No 37 (Incandescent filament light sources) and Regulation No 99 (gas discharge light sources). Light emitting diode (LED) modules and distributed lighting systems may also be used.

The cut-off and the gradient definitions.

The photometric requirements permit the use of asymmetrical beam distributions.

The front fog lamps shall be so designed and constructed that in normal use, despite the vibrations to which they may then be subjected, their satisfactory operation continues to be ensured and they retain the characteristics prescribed by this Regulation. The correct position of the lens shall be clearly marked and the lens and reflector shall be so secured as to prevent any rotation during use. Conformity with the requirements of this paragraph shall be verified by visual inspection and, where necessary, by a trial fitting.

Or, Regulation No 99 and its series of amendments in force at the time of application for type approval,

5.7.2.

And/or, one or more LED modules where the requirements of Annex 12 to this Regulation shall apply; compliance with these requirements shall be tested.

6.4.1.2. In the case of a gas-discharge light source:

A standard light source shall be used as specified in Regulation No 99, which has been aged during at least 15 cycles, in accordance with Annex 4, paragraph 4 of Regulation No 99.

During testing of the front fog lamp the voltage at the terminals of the ballast or at the terminals of the light source in case the ballast is integrated with the light source shall be regulated to maintain 13,2 V for a 12 V system, or at the vehicle voltage as specified by the applicant, with a tolerance of ± 0,1 V.

The objective luminous flux of the gas-discharge light source may differ from that specified in Regulation No 99. In this case, the luminous intensity values shall be corrected accordingly.

6.4.1.3. In the case of non-replaceable light sources:

All measurements on front fog lamps equipped with non-replaceable light sources shall be made at 6,3 V, 13,2 V or 28,0 V or at other vehicle voltage as specified by the applicant. The test laboratory may require from the applicant the special power supply needed to supply the light sources. The test voltages shall be applied to the input terminals of the lamp.

6.4.1.4. In the case of LED modules:

All measurements on front fog lamps equipped with LED module(s) shall be made at 6,3 V, 13,2 V or 28,0 V respectively, if not otherwise specified within this Regulation. LED modules operated by an electronic light source control gear shall be measured with the input voltage as specified by the applicant or with a supply and operating device which replace this control gear for the photometric test. The relevant input parameters (e.g. duty cycle, frequency, pulse shape, peak voltage) shall be specified and stated in the communication form, item 10.6, in Annex 1 to this Regulation.

6.4.1.5. Compliance with the requirement in paragraph 5.8.1 shall be verified at least with respect to the values in line 3 and 4 of table in paragraph 6.4.3.

6.4.2.1.

The aiming screen for visual adjustment (see Annex 4 paragraph 2.2) shall be positioned at either a distance of 10 m or a distance of 25 m in front of the front fog lamp.

6.4.2.2.

The beam shall produce on this aiming screen, over a width of not less than 5,0 degrees on both sides of the line v, a symmetrical and substantially horizontal cut-off to enable visual vertical adjustment. In the case that visual aim leads to problems or ambiguous positions, the measurement of the cut-off quality and the instrumental method as specified in paragraphs 4 and 5 of Annex 9 shall be applied.

6.4.2.3.

The front fog lamp shall be adjusted so that the cut-off on the screen is 1° below the line h according to the requirements in paragraph 2 of Annex 9.

6.4.3. Photometric requirements:

When so adjusted, the front fog lamp shall meet the photometric requirements in the table below (refer also to Annex 4, paragraph 2.2 of this Regulation):

6.4.3.1.

The luminous intensity shall be measured either with white light or coloured light as prescribed by the applicant for use of the fog lamp in normal service. Variations in homogeneity detrimental to satisfactory visibility in the zone above the line 5 from 10 degrees left to 10 degrees right are not permitted.

6.4.3.2.

At the request of the applicant, two front fog lamps constituting a matched pair corresponding to paragraph 4.2.2.5 may be tested separately. In this case the specified requirements for lines 6, 7, 8, 9 and the Zone D in the table in paragraph 6.4.3 apply to half the sum of readings of the right-hand and left-hand side front fog lamp. However each of the two front fog lamps shall meet at least 50 per cent of the minimum value required for line 6. Additionally, each of the two front fog lamps that constitute the matched pair corresponding to paragraph 4.2.2.5 are only required to meet the requirements of line 6 and line 7 from 5° inwards to 10° outwards.

6.4.3.3.

Inside the field between lines 1 to 5 in Figure 3 of Annex 4, the beam pattern should be substantially uniform. Discontinuities in intensities detrimental to satisfactory visibility between the lines 6, 7, 8 and 9 are not permitted.

6.4.3.4.

In the light-distribution as specified in the table in paragraph 6.4.3, single narrow spots or stripes inside the area including the measuring points 1 to 10 and line 1 or inside the area of line 1 and line 2 with not more than 175 cd are allowed, if not extending beyond a conical angle of 2° aperture or a width of 1°. If multiple spots or stripes are present they shall be separated by a minimum angle of 10°.

6.4.3.5.

If the specified luminous intensity requirements are not met, a re-aim of the cut-off position within ± 0,5° vertical and/or ± 2° horizontal is allowed. In the re-aimed position all photometric requirements shall be met.

6.4.4. Other photometric requirements

6.4.4.1. In the case of front fog lamps equipped with gas-discharge light sources with the ballast not integrated with the light source, the luminous intensity shall exceed 1 080 cd in the measuring point at 0° horizontal and 2° D vertical, four seconds after activation of the fog lamp which has not been operated for 30 minutes or more.

6.4.4.2. To adapt to dense fog or similar conditions of reduced visibility, it is permitted to automatically vary the luminous intensities provided that:

(a)	An active electronic light source control gear is incorporated into the front fog lamp function system.

(b)	All intensities are varied proportionately.

The system, when checked for compliance according to the provisions of paragraph 6.4.1.1.3, is considered acceptable if the luminous intensities remain within 60 per cent and 100 per cent of the values specified in the table in paragraph 6.4.3.

6.4.4.2.1.

An indication shall be inserted in the communication form (Annex 1, paragraph 10).

6.4.4.2.2.

The Technical Service responsible for type approval shall verify that the system provides automatic modifications, such that good road illumination is achieved and no discomfort is caused to the driver or to other road users.

6.4.4.2.3.

Photometric measurements shall be performed according to the applicant’s description.

7. COLOUR

The colour of the light emitted by the front fog lamp shall be either white or selective yellow by choice of the applicant. The selective yellow colour, if any, of the beam may be obtained either by the colour of the light source or by the lens of the front fog lamp or by any other suitable means.

7.1.

The colorimetric characteristics of the front fog lamp shall be measured with voltages as defined in paragraphs 6.3 and 6.4.
