5.1 General requirements

5.1.1 The system or its components can still meet the requirements of use AND meet the requirements of this standard, even if they are subjected to vibration, under normal conditions of use.

5.1.3 The system shall use light sources, which comply with GB 15766.1 and/or ECE

R37 and ECE R99, except for the use of LED modules. The light source used shall meet the following requirements.

5.1.4 The system shall comply with the provisions of A.2 and A.3.

5.1.5 If the optical lens of the system is made of plastic material, it shall also comply with the provisions of Appendix B.

5.1.6 For any mechanical, electro-mechanical or other device, which is combined with the lighting unit and used to control beam conversion, on a system or its components as designed to be switchable between high beam and low beam, its structure shall meet the following requirements.

5.1.7 The designed system can provide a failure signal, when a light source and/or an

LED module fails. The installation of the failure signal indicator shall comply with the requirements of E.2.7.5.2.

5.3 Photometric performance

5.3.1 General provisions

5.3.3.

5.3.1.4 Photometric measurements shall be carried out, as described by the manufacturer, as follows.

5.3.2 Photometric requirements for low beam

5.3.2.1 Before the start of the test, set the system to a neutral state AND emit a class C (basic) low beam.

5.3.4 Other photometric requirements

5.3.4.1 For a system or its components, which are equipped with one or more adjustable lighting units, shall meet the requirements of 5.3.2 and 5.3.3, at each installation position (dimming range), as shown in a) and b) below.

5.3.4.2 For a system or its components, which are equipped with one or more adjustable lighting units, shall meet the following conditions.

7.1 General requirements for testing

7.1.1 The test darkroom, devices, equipment shall comply with the provisions of GB

4599-2007.

7.1.2 The voltage and test luminous flux, during the photometric test, shall meet the following requirements.

7.1.3 The test sequence shall be in accordance with Appendix F.

7.2 Photometric measurement

7.2.1 General requirements for photometric measurement

7.2.1.4 The photometric measurement distance is 25 m; the measured illuminance value or light intensity value is perpendicular to the measurement direction.

7.2.1.5 The angle coordinates are determined, according to the specified spherical coordinates (angle unit. degrees), which is equivalent to that the goniometer has a horizontal axis (with a certain elevation angle) fixed to the ground, AND another movable (rotation) axis perpendicular to the horizontal fixed axis.

7.2.1.9 The lighting units of the system shall be measured one by one. However, two or more lighting units of one installation unit can be measured, at the same time, provided that -- they use the same type of light source AND have their own input power supply (power supply can be controlled or uncontrolled); the dimensions and positions are such that the luminous surface of these lighting units is completely contained within a rectangle, which has a horizontal extension of not more than 300 mm and a vertical extension of not more than 150 mm; the manufacturer specifies a common reference center.

7.2.2.2 When a replaceable gas discharge light source is used, use the standard gas discharge light source, which is specified in GB 15766.1 or ECE R99; the photometric measurement shall be carried out, after at least 15 cycles of aging. If at least one standard light source is used in the measurement, AND its photometric performance meets the corresponding requirements of this standard, THEN, the system or its components are considered to meet the requirements. The luminous flux of the gas discharge light source can be different from the target value, which is specified in GB

15766.1 or ECE R99.At this time, the measured photometric value shall be corrected in time; the correction factor is 0.7.

7.2.3 Measurement of bending mode

When the system or its components provide a bending mode, the requirements of 5.3.2 and/or 5.3.3 apply to all lighting states of the system or its components, under various turning radii of the vehicle. The following procedures shall be followed, for the detection of high and low beam in the bending mode of the curve.

7.2.4 Measurement test for functional units of AFS system or its components

equipped with LED modules

7.2.4.1 All specimens shall be tested, in accordance with 7.2.4.4.

7.2.4.2 The measurement environment of optoelectronic properties shall comply with the provisions in 6.1 of GB 25991-2010.

7.2.4.3 Before the test, the LED module shall be subjected to 15 h LED light source aging; then cooled to room temperature.

7.2.4.4 The test shall meet the following requirements.

8.1 Determination of system type

The determination of the system type shall be in accordance with the provisions of

Chapter 4.

8.2 Compliance with type inspection and production consistency

The system shall be subject to type inspection and production consistency inspection.

If the corresponding provisions of 8.3 or 8.4 are met, the system is considered to have passed the type inspection or consistency inspection.

8.3 Type inspection

8.3.2 Each system sample shall comply with the provisions of Chapters 5 and 6.

8.3.3 The system samples shall comply with the requirements of the photometric stability test, in Appendix A. If LED modules are used, the corresponding functional units of the system shall also meet the requirements of temperature stability, chromaticity stability, target luminous flux, in Appendix A.

8.3.4 For the system samples, which use plastic photometric lens, shall also meet the requirements of Appendix B plastic photometric lens system.

8.4 Production consistency inspection

8.4.1 For products that have passed the type inspection, samples randomly selected from batches of products are used to determine the consistency of their production.

Samples with obvious appearance defects will not be considered.
