The light–emitting surface of the headlamp shall be clean and the headlamp cleaner shall be in the stationary position. The photometric measurements shall be made in compliance with the specifications of the relevant Regulation, as well as the measurements prescribed in paragraph 4 below. The illumination shall then be measured at the measuring points specified in paragraph 7 of this Regulation.

4.   EVALUATION OF CLEANING EFFICIENCY

| 4.1. | After the headlamp(s) has been operated for 10 minutes the dirt mixture shall be applied evenly to its entire light–emitting surface using the spray gun mentioned above. The mixture shall then be dried either by operating the headlamp or using hot air. This procedure shall be repeated, if necessary until the luminous intensity in all measuring points has been reduced below 20 per cent of the values according to paragraph 3 of this annex. At least the luminous intensity in one of the several measuring points shall be between 15 and 20 per cent. |
| --- | --- |

4.1.

| 4.1.1. | The values to be used during the tests for the duration of the cleaning period and the consumption of cleaning fluid during this period shall be the values declared by the manufacturer. The fluid consumption shall be measured as the mean value over several cleaning periods as specified by the manufacturer. |
| --- | --- |

4.1.1.

| 4.1.2. | After the headlamp has cooled down and not later than two hours after the dirt has dried the headlamps shall be switched on and the headlamp cleaner shall be operated for the cleaning period specified by the manufacturer. This cleaning period shall not exceed 10 s. |
| --- | --- |

4.1.2.

| --- | --- |

4.2.

| 4.3. | If the cleaner is designed to be manually operated, the cleaning shall be accomplished with a maximum of five operations within the time-limit specified in paragraph 4.1.2 above. |
| --- | --- |

4.3.

| 4.4. | Where the cleaner is not electrically operated, the operating conditions for the test shall be specified by the technical service in accordance with the manufacturer. |
| --- | --- |
