         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.
            
         
               (c)
            
            
               The cut-off and the gradient definitions.
            
         
               (d)
            
            
               The photometric requirements permit the use of asymmetrical beam distributions.

         6.4.3.1.   The illumination 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.
   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 120 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.
   Other photometric requirements
   6.4.4.1.   In the case of front fog lamps equipped with gas-discharge light sources the luminous intensity shall exceed 800 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.
   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 6.4.1.1.2, 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 foglamp 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.
   8.   DETERMINATION OF DISCOMFORT (DAZZLE)
   The discomfort dazzle caused by the front fog lamp shall be determined (10).
   9.   MODIFICATIONS OF THE TYPE OF FRONT FOG LAMP AND EXTENSION OF APPROVAL
   Every modification of the type of front fog lamp shall be notified to the administrative department which approved the type of front fog lamp. The department may then either:
   9.1.1.   consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the front fog lamp still complies with the requirements;
   or
   9.1.2.   require a further test report from the technical service responsible for conducting the tests.
   9.2.   Confirmation or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 4.1.4 to the Parties to the Agreement which apply this Regulation.
   9.3.   The competent authority issuing the extension of approval shall assign a series number for such an extension and inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex 1 to this Regulation.

         APPENDIX 2
         Method of measurement of the diffusion and transmission of light
         1.   EQUIPMENT (SEE FIGURE)
         The beam of a collimator K with a half divergence β/2 = 17,4 × 10–4 rd is limited by a diaphragm DT 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 DT 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 ß/2 = 14°.
         An annular diaphragm DD with angles a/2 = 1° and amax/2 = 12° 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 DT and the focal length F2
             (1) of the lens L2 shall be so chosen that the image of DT completely covers the receiver R.
         When the initial incident flux is referred to 1 000 units, the absolute precision of each reading shall be better than 1 unit.
         2.   MEASUREMENTS
         The following readings shall be taken:

         1.   TEST EQUIPMENT
         1.1.   Spray gun
         The spray gun used shall be equipped with a nozzle 1,3 mm in diameter allowing a liquid flow rate of 0,24 ± 0,02 1/minute at an operating pressure of 6,0 bars – 0, + 0,5 bar.
         Under these operation conditions the fan pattern obtained shall be 170 mm ± 50 mm in diameter on the surface exposed to deterioration, at a distance of 380 mm ± 10 mm from the nozzle.
         1.2.   Test mixture
         The test mixture shall be composed of:
         Silica sand of hardness 7 on the Mohs scale, with a grain size between 0 and 0,2 mm and an almost normal distribution, with an angular factor of 1,8 to 2;
         Water of hardness not exceeding 205 g/m3 for a mixture comprising 25 g of sand per litre of water.
         2.   TEST
         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:
         Δ d = (T5 – T4) / T2 ≤ 0,0250 ± 0,0025

         APPENDIX 4
         ADHESIVE TAPE ADHERENCE TEST
         1.   PURPOSE
         This method allows the determination under standard conditions of the linear force of adhesion of an adhesive tape to a glass plate.
         2.   PRINCIPLE
         To measure the force necessary to un-stick an adhesive tape from a glass plate at an angle of 90°.
         3.   SPECIFIED ATMOSPHERIC CONDITIONS
         The ambient conditions shall be at 23 °C ± 5 °C and 65 ± 15 per cent relative humidity (RH).
         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.).
         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 carried out under the ambient conditions specified in paragraph 3.
         Take the five test pieces while unrolling the tape radially at a speed of approximately 300 mm/s and then apply them within 15 seconds in the following manner:
         Apply the tape to the glass plate progressively with a slight longitudinal rubbing movement of the finger, without excessive pressure to the tape and to the glass plate.
         Leave the assembly in the specified atmospheric conditions for 10 minutes.
         Unstuck 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°. 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 un-stick the tape 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 the result of the measurement. This value shall be expressed in Newton per centimetre of width of the tape.
      
   
   
      ANNEX 7
      Minimum requirements for conformity of production control procedure
      1.   GENERAL
      1.1.   The conformity requirements shall be considered to be satisfied from a mechanical and geometric standpoint, if the differences do not exceed inevitable manufacturing deviations within the requirements of this Regulation.
      With respect to photometric performances, the conformity of mass-produced front fog lamps shall not be contested if the photometric performances according to the requirements in Annex 2 to this Regulation depending on the prevailing class of front fog lamps are satisfied.
      If the results of the tests described above do not meet the requirements, tests on the front fog lamp shall be repeated using light sources as specified in paragraphs 6.3 or 6.4 of this Regulation, as appropriate.
      1.2.1.   If the results of the tests described above do not meet the requirements, the alignment of the front fog lamp may be changed, provided that the axis of the beam is not displaced laterally by more than 0,5° to the right or left and not by more than 0,2° up or down. In the re-aimed position all photometric requirements shall be met.
      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:
      1.3.1.   One of the sampled front fog lamps shall be tested according to the procedure described in paragraph 2.1 of Annex 5 after being subjected three consecutive times to the cycle described in paragraph 2.2.2 of Annex 5.
      1.3.2.   The front fog lamp shall be considered as acceptable if Δr does not exceed 3,0 mrad. If this value exceeds 3,0 mrad but is not more than 4,0 mrad, a second front fog lamp shall be subjected to the test after which the mean of the absolute values recorded on both samples shall not exceed 3,0 mrad.
      1.4.   The chromaticity coordinates shall comply with paragraph 7. of this Regulation. The photometric performance of a front fog lamp emitting an enlarged selective yellow light when equipped with a colourless light source shall be the values contained in this Regulation multiplied by 0,84.
      2.   MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER
      For each type of front fog lamp the holder of the approval mark shall carry out at least the following tests, at appropriate intervals. The tests shall be carried out in accordance with the provisions of this Regulation. If any sampling shows non-conformity with regard to the type of test concerned, further samples shall be taken and tested. The manufacturer shall take steps to ensure the conformity of the production concerned.
      2.1.   Nature of tests
      Tests of conformity in this Regulation shall cover the photometric characteristics and the verification of the change in vertical position of the cut-off line under the influence of heat.
      2.2.   Methods used in tests
      2.2.1.   Tests shall generally be carried out in accordance with the methods set out in this Regulation.
      2.2.2.   In any test of conformity carried out by the manufacturer, equivalent methods may be used with the consent of the competent authority responsible for approval tests. The manufacturer is responsible for proving that the applied methods are equivalent to those laid down in this Regulation.
      2.2.3.   The application of paragraphs 2.2.1 and 2.2.2 requires regular calibration of test apparatus and its correlation with measurements made by a competent authority.
      2.2.4.   In all cases the reference methods shall be those of this Regulation, particularly for the purpose of administrative verification and sampling.
      2.3.   Nature of sampling
      Samples of front fog lamps shall be selected at random from the production of a uniform batch. A uniform batch means a set of front fog lamps of the same type, defined according to the production methods of the manufacturer.
      The assessment shall in general cover series production from individual factories. However, a manufacturer may group together records concerning the same type from several factories, provided these operate under the same quality system and quality management.
      2.4.   Measured and recorded photometric characteristics
      The sampled front fog lamp shall be subjected to photometric measurements at the points provided for in the Regulation, the reading being limited to points listed in Annex 2 to this Regulation depending on the prevailing class of front fog lamps.
      2.5.   Criteria governing acceptability
      The manufacturer is responsible for carrying out a statistical study of the test results and for defining, in agreement with the competent authority, criteria governing the acceptability of his products in order to meet the specifications laid down for verification of conformity of products in paragraph 10.1 of this Regulation.
      The criteria governing the acceptability shall be such that, with a confidence level of 95 per cent, the minimum probability of passing a spot check in accordance with Annex 8 (first sampling) would be 0,95.

      With respect to the verification of the change in vertical positions of the cut-off line under the influence of heat, the following procedure shall be applied:
      One of the front fog lamps of sample A after sampling procedure in Figure 1 of this annex 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 5.
      The front fog lamp shall be considered as acceptable if Δr does not exceed 3,0 mrad.
      If this value exceeds 3,0 mrad but is not more than 4,0 mrad, the second front fog lamp of sample A shall be subjected to the test after which the mean of the absolute values recorded in both samples shall not exceed 3,0 mrad.
      However, if this value of 3,0 mrad on sample A is not complied with, the two front fog lamps of sample B shall be subjected to the same procedure and the value of Δr for each of them shall not exceed 3,0 mrad.

      Definition and sharpness of the cut-off line and aiming procedure by means of this cut-off line for class F3 front fog lamps
      1.   GENERAL
      The luminous intensity distribution of the front fog lamp shall incorporate a cut-off line that enables the front fog lamp to be adjusted correctly for the photometric measurements and for the aiming on the vehicle. The characteristics of the cut-off line shall comply with the requirements set out in paragraphs 2 to 4.
      2.   SHAPE OF THE CUT-OFF LINE
      For visual adjustment of the front fog beam the cut-off line shall provide: a horizontal line for vertical adjustment of the front fog lamp extending to 4° either side of the v-v line (see Figure 1).

         Shape and position of the ‘cut-off’ line
      
      
         
      3.   ADJUSTMENT OF THE FRONT FOG LAMP
      3.1.   Horizontal adjustment
      The cut-off line shall be so positioned that the projected beam pattern appears approximately symmetrical to the v-v line. When the front fog lamp is designed for use in pairs or has otherwise an asymmetric beam pattern, it shall be horizontally aligned according to the specification of the applicant, or otherwise in such a way that the cut-off line appears symmetrical to the v-v line.
      3.2.   Vertical adjustment
      After horizontal adjustment of the front fog beam according to paragraph 3.1, the vertical adjustment shall be performed in such a way that the cut-off line is moved upwards from the lower position until it is situated on the v v line at 1° below the h-h line. If the horizontal part is not straight but slightly curved or inclined, the cut-off line shall not exceed the vertical range formed by two horizontal lines which are situated between 3° left and right of the v-v line at 0,2° above and below the nominal position of the cut-off (see Figure 1).
      3.2.1.   When the vertical positions of three attempts to adjust the cut-off differ by more than 0,2°, the horizontal part of the cut-off line is assumed not to provide sufficient linearity or sharpness for performing visual adjustment. In this case the quality of cut-off shall be tested instrumentally for compliance with requirements as follows.
      4.   MEASUREMENT OF THE QUALITY OF CUT-OFF
      Measurements shall be performed by vertically scanning through the horizontal part of the cut-off line in angular steps not exceeding 0,05°
      At either a measurement distance of 10 m and a detector with a diameter of approximately 10 mm.
      Or at a measurement distance of 25 m and a detector with a diameter of approximately 30 mm.
      The measurement of the cut-off quality shall be considered acceptable if the requirements of the paragraphs 4.1.1 to 4.1.3 of this annex shall comply with at least one measurement at 10 m or 25 m.
      The measuring distance at which the test was determined shall be recorded in paragraph 9. of the communication form in Annex 2 of this Regulation.
      The scanning is performed from downwards upwards through the cut-off line along the vertical lines at –2,5° and +2,5° from the v-v line. When so measured, the quality of the cut-off line shall meet the following requirements:
      4.1.1.   Not more than one cut-off line shall be visible.
      4.1.2.   Sharpness of cut-off:
      If scanned vertically through the horizontal part of the cut-off line along vertical lines at ± 1° from the v-v line, the maximum value measured for the sharpness factor G of the cut-off line shall not be less than 0,08 where:
      G = (log EV – log E (V + 0,1°))
      4.1.3.   Linearity
      The part of the cut-off line which serves vertical adjustment shall be horizontal from 3° left to 3° right of the v-v line. This requirement is satisfied, if the vertical positions of the inflection points according to paragraph 3.2 at 3° left and right of the v-v line do not deviate by more than ±0,20°.
      5.   INSTRUMENTAL VERTICAL ADJUSTMENT
      If the cut-off line complies with the above quality requirements, the vertical beam adjustment can be performed instrumentally. For this purpose the inflection point where d2 (log E) / dv2 = 0 is positioned on the v-v line and below the h-h line. The movement for measuring and adjusting the cut-off line shall be upwards from below the nominal position.

            Values according to ‘IRPA/INIRC Guidelines on limits of exposure to ultraviolet radiation’. Wavelengths (in nanometres) chosen are representative; other values should be interpolated.
      4.7.   Temperature stability
      4.7.1.   Luminous intensity
      4.7.1.1.   Filament lamps and gas discharge light sources are exempted from this test.
      4.7.1.2.   A photometric measurement shall be made after 1 minute of operation with the device at room temperature. The test point to be measured is horizontal 0° vertical 2,5°D.
      4.7.1.3.   The lamp shall continue operation until photometric stability has occurred. The moment at which the photometry is stable is defined as the point in time at which the variation of the photometric value is less than 3 per cent within any 15-minute period. After stability has occurred, aiming for complete photometry shall be performed in accordance with requirements of the specific device. Photometry at all test points is required for the specific device.
      4.7.1.4.   Calculate the ratio between the photometric test point values determined in paragraph 4.7.1.2 and the values determined in paragraph 4.7.1.3 once stability of photometry has been achieved.
      4.7.1.5.   Apply the ratio calculated in paragraph 4.7.1.4 to each of the remainder of the test points to create a new photometric table that describes the complete photometry based on 1 minute of operation.
      4.7.1.6.   The illuminance values measured after one minute and until photometric stability has occurred, shall comply with the minimum and maximum requirements.
      4.7.2.   Colour
      The colour of the light emitted, measured after 1 minute and measured after 30 minutes of operation, shall be within the required colour boundaries in both instances.
