The waterproof performance test of solar street lights is mainly carried out through a series of standardized procedures to ensure that its products can work normally under various environmental conditions. The following is a summary of the detailed steps and key points of the waterproof performance test of solar street lights:

First, the purpose of testing

Verify the waterproof performance of solar street lights to ensure that they can operate normally in harsh environments.

Second, test standards

The standards used in the test usually include GB/T 4208-2017 "Shell Protection Grade (IP code)", etc. These standards specify the conditions and evaluation criteria of the test in detail.

Third, test steps

1. Preparation stage:

- Select a test location, usually in a professional testing laboratory.

- Prepare test equipment, including test pool, power supply, water source, etc.

- Ensure that the sealing ring of the solar street lamp is intact, without damage or aging.

2. Test process:

- Solar street lights are placed in the center of the test pool.

- Adjust the water level of the test tank to ensure that the water level height is not lower than a certain distance above and below the lamp (such as 20cm) to simulate the actual use of water flooding.

- Turn on the power of the solar street lamp, and turn on the lamp to observe its working state in the water.

- Hold for a certain period of time (such as 10 minutes) to test the continuous working ability of the street lamp in water.

3. Result judgment:

- Remove the solar street lights from the test pool.

- Carefully check whether there is water seepage inside the street lamp.

- If there is no water seepage, it means that the solar street light has passed the waterproof test; If there is water seepage, it is not passed.

Fourth, precautions

The test water quality should be tap water or distilled water to avoid the impact of corrosive water quality on the test results.

During the test, the solar street light should be kept stable and not shaken to ensure the accuracy of the test results.

Before testing, the appearance and internal structure of solar street lights should be checked to ensure that there is no damage or abnormal conditions.

Through the above steps, the waterproof performance of solar street lights can be effectively tested, so as to ensure that it can withstand bad weather conditions in actual use and maintain normal working conditions.
