8.1.2.2 the battery shall meet the requirements of 6.2.2 when it is cloudy or rainy for 2 to 7 consecutive days.
8.1.3 charge-discharge controller (6.3)
8.1.3.1 the performance of charge-discharge controller shall be tested according to 8.2.2 ~ 8.2.12 of GB/T19064 and shall meet its requirements.
8.1.3.2 environmental temperature test put the controller in the thermostat and conduct 10 temperature cycle tests from the lowest to the highest ambient temperature, each cycle time being 4h. After the test, the controller should work normally at the lowest and highest ambient temperatures respectively (6.3.2).
8.1.3.3 direct - alternating current inverter (when the device is used) shall be tested according to GB/T19064 provisions of 8.4.2 ~ 8.4.11, and shall meet its requirements, and meet the requirements of 6.3.4.
8.1.4 lighting components (6.4.)
8.1.4.1 the electric light source shall be tested in accordance with the relevant national standards and shall conform to its provisions and 6.4.1 requirements.
8.1.4.2 the dc electronic ballast shall be tested in accordance with the detection methods specified in GB 19510.1, GB 19510.5 and GB/T 19656 and shall conform to the provisions thereof. 6.4.2 requirements shall be met.
8.1.4.3 the safety performance of lamps and lanterns shall be tested according to the detection methods specified in GB 7000.1 and GB 7000.5.
Optical characteristics shall be tested in accordance with GB/T 9468, and the test results shall meet its requirements and meet the requirements of 6.4.3.
The optical inspection report shall include: polar coordinate light intensity distribution curve, isointensity curve, road surface isoluminosity curve, luminous transmittance ratio of lamps and lanterns and lamp efficiency, etc. To road illume lamps and lanterns, still should include light intensity to distribute table, use coefficient curve to wait.
