Its compliance shall be determined by testing. 5.5.4.3 AND/OR light source generator, which shall meet the requirements of Appendix C. Its compliance shall be determined by testing. 5.6 Sharpness and linearity requirements for cut-off lines When there is an objection to the sighting, for the grade-F3 front fog lamps, it shall be tested for the sharpness and linearity of the cut-off line, in accordance with the provisions of Appendix D. 5.7 Electromagnetic compatibility requirements Front fog lamps and their ballasts OR electric light source controllers shall comply with electromagnetic compatibility requirements. The consistency of electromagnetic compatibility requirements is related to the specific vehicle type. 5.8 Other requirements 5.8.1 The front fog lamp can use an additional system, to control the light intensity; OR when mixed with another function, the additional system can also be used to control the light intensity. 6.4.1.1.1 There shall be at least one complete set of front fog lamps; the standard bulbs can be provided by the manufacturer or the applicant. For the case where the filament bulb directly uses the vehicle voltage: The front fog lamp test shall use the colorless standard filament bulb in GB 15766.1 or R37 Regulation. The test voltage shall use the voltage specified to the reference luminous flux, which is obtained at 13.2 V, on the data page of GB 15766.1 or Regulation No. R37. 6.4.1.1.2 For lamps that use electric light source controllers, as part of the front fog lamp system, the voltage of the input terminals of the lamps shall be as specified by the manufacturer or the applicant. 6.4.1.1.3 For lamps that use an electric light source controller, which is not part of the front fog lamp system, the voltage published by the manufacturer or the applicant shall apply to the input terminal of the electric light source controller. The manufacturer or applicant shall provide the electric light source controller for the luminaire. 6.4.1.2 For front fog lamps using gas discharge light sources A standard gas discharge light source, which meets the requirements of GB 15766.1 or ECE R99 Regulations AND has undergone 15 cycles of aging in accordance with G.4 of GB 15766.1 or Article 4 of Annex 4 of ECE R99 Regulation, shall be used. When the front fog lamp is tested, for the 12 V system, the terminal voltage of the ballast terminal or the integrated rectifier and the light source shall be kept at 13.2 V, OR at the vehicle voltage (±0.1 V) as stated by the manufacturer or the applicant. The luminous flux of the gas discharge light source may be different from that described in GB 15766.1 or ECE R99 Regulation; in this case, the luminous intensity value shall be appropriately corrected. 6.4.1.3 For front fog lamps with non-replaceable light sources For all front fog lamps, which are equipped with non-replaceable light sources, the voltage shall be 6.3 V, 13.2 V or 28.0 V, OR according to the vehicle voltage, which is described by the manufacturer or the applicant. The manufacturer or applicant shall provide a specific power source. The test voltage shall be applied to the input terminals of the luminaire. 6.4.1.4 For front fog lamps using LED modules If not otherwise specified, the test voltage of the front fog lamps, which are equipped with LED modules, shall be the corresponding 6.3 V, 13.2 V or 28.0 V. The LED module, which is controlled by the electric light source controller, shall be measured according to the input voltage, which is specified by the manufacturer or the applicant; OR by the operating device and power supply that replaces the electric light source controller. The corresponding input parameters (such as duty cycle, frequency, pulse shape, peak voltage) shall be stated in the submission. Among them, judge whether the LED module meets the requirements of 5.5.2.1, by testing whether the line 3 and line 4 in Table 2 meet the requirements. 6.4.2 Sighting method of grade-F3 front fog lamp 6.4.2.1 The sighting screen for visual calibration, as shown in Figure 3, shall be placed 10 m or 25 m in front of the front fog lamps. 6.4.2.2 According to the provisions of D.2, the light and dark cut-off line of the front fog lamps shall be adjusted to a position 1° below the H line. 6.4.2.3 When there is a problem with visual sighting or the position of the cut-off line is ambiguous, .......
