GB18099-2000
The technical content of this standard is equivalent to the technical regulation ECER91 (effective in June 1993) formulated by the United Nations Economic Commission for Europe, "Uniform Provisions on the Certification of Side Marker Lamps for Motor Vehicles and Their Trailers" (E/ECE/324, E/ECE/TRANS/505, Rev.1/Add.90, 15July1993). The main technical differences from ECER91 are: in order to be consistent with the technical requirements of GB4785, the minimum geometric visibility angle and the geometric visibility diagram requirements of SM1 and SM2 lamps are not specified.
In order to make the test more accurate and fair, the sentence 4.3.2.3 "Except the direction of the reference axis" is added. According to actual needs, the requirements of Regulation 2.4 on the uniformity of the area within the grid are not adopted. This standard is proposed by the Ministry of Machinery Industry of the People's Republic of China. This standard is under the jurisdiction of the National Automobile Standardization Technical Committee. This standard is drafted by the National Passenger Car Quality Supervision and Inspection Center. The main drafters of this standard are Liu Xin and Xuan Yi. 223

Implementation on January 1, 2001
For multi-light source lamps:
GB 18099—2000
When any one light source fails, it shall still meet the minimum luminous intensity requirements; when all light sources are lit, the maximum luminous intensity shall not exceed the specified value.
4.3.2 The minimum geometric visibility angle of each side marker lamp shall comply with the provisions of GB4785, and the luminous intensity shall comply with the following provisions: 4.3.2.1 The luminous intensity of SM1 side marker lamps in each measuring direction shown in Figure 1 and SM2 side marker lamps in each measuring direction shown in Figure 2 shall not be less than the minimum value specified in Table 1. The degrees in the figure are the horizontal angle and vertical angle with the hh, V-line. 10°

Figure 2 SM2 side marker light distribution table
4.3.2.2 The luminous intensity of the side marker lamps in any visible direction shall not be greater than the maximum value specified in Table 1. 30°
4.3.2.3 For SM1 and SM2 side marker lamps, the inspection agency may select 5 points for measurement at random in addition to the reference axis direction when conducting the inspection.
5 Test method
5.1 The darkroom, devices and equipment for the test shall comply with the provisions of GB4599. 5.2 Voltage or luminous flux during photometric measurement
5.2.1 For non-lamp-replaceable lamps, the measurement shall be carried out at a voltage of 13.5V or 28.0V. 5.2.2 For lamps with replaceable lamps, the corresponding standard lamps shall be used and the measurement shall be carried out at the reference luminous flux of the type of lamp specified in GB15766.1.
5.3 Before the photometric test, the lamp shall be ignited at the voltage used during the test so that its optical performance tends to be stable. The distance of the photometric test shall ensure the application of the inverse square law of distance.

5.7.1 For non-bulb replacement or other light sources: 225
GB 18099-2000
Check the photometric performance at the voltage specified by the manufacturer. The laboratory may require the manufacturer to provide the special power supply required for this type of lamp. 5.7.2 For bulb replacement light sources:
When testing with mass-produced bulbs, at 13.5V or 28.0V, its luminous intensity should be between the minimum and maximum values ​​specified in Table 1, and corrected according to the luminous flux deviation of the bulb used as specified in Chapter 5 of GB15766.1-1995; or, standard bulbs can be used in turn at each bulb position, measured at the specified reference luminous flux and accumulated. 5.8 When checking the chromaticity characteristics, the color temperature of the light source is 2856K, which is equivalent to the light source A recommended by the International Commission on Illumination. However, for non-bulb-replaceable side marker lamps, the light source voltage should be set to 13.5V or 28.0V when checking the chromaticity characteristics. 6 Inspection rules
