What are the safety precautions for IPX5 test of electric scooters?

When conducting IPX5 waterproof test of electric scooters, special attention should be paid to the following safety precautions:

Preparation before testing
Check the integrity of the equipment: Before testing, make sure that all parts of the electric scooter are properly installed and not loose. Check the sealing of key components such as batteries, motors, and controllers to ensure that they meet the IPX5 waterproof standard.
Confirm that the test environment is safe: The test site should be away from flammable and explosive items to avoid the risk of fire or explosion during the test.
Wear protective equipment: Testers should wear appropriate protective equipment such as waterproof clothing, insulating gloves, and safety helmets to prevent accidental contact with water or electrical equipment.

Precautions during testing
Comply with test standards: Strictly test in accordance with GB4208-2017/IEC60529:2013 standard. Ensure that the inner diameter of the nozzle is 12.5mm, the water flow rate is (12±0.5)L/min, and the distance between the nozzle and the shell surface is kept between 2.5m~3m.
Control test time: According to the surface area of ​​the shell of the sample under test, the water spraying time per square meter is about 1 minute, and the total test time is not less than 3 minutes.
Avoid direct contact: During the test, avoid direct contact with the water spraying device and the electric scooter to prevent danger caused by high-pressure water flow or leakage of electrical equipment.
Monitor equipment status: Pay close attention to the status of the electric scooter during the test to ensure that no abnormal situation occurs during the water spraying process.

Post-test inspection
Check waterproof performance: After the test, immediately check the internal components of the electric scooter to ensure that no water drops enter the shell. If water is found to have entered, stop using it immediately and repair it.
Check equipment function: Confirm that all functions of the electric scooter can still work normally after the waterproof test. Including whether the functions of the motor, brake, steering, etc. are normal, to ensure that the equipment can still be used safely after the test.
Drying treatment: Even if the test passes, the electric scooter should be dried after the test to prevent residual moisture from causing potential damage to the equipment.

Other safety suggestions
Avoid extreme weather testing: Do not perform IPX5 testing under extreme weather conditions such as heavy rain and thunderstorms.
Follow the instructions: After the test is completed, strictly follow the instructions of the electric scooter for subsequent operations, and avoid riding on wet or flooded roads.
Regular maintenance: Regularly check the waterproof seals of the electric scooter to ensure that it maintains good waterproof performance during daily use.
By following the above safety precautions, you can effectively reduce the risks that may occur during the IPX5 waterproof test, ensure the smooth progress of the test and the safe use of the equipment.

How long does it take to use the electric scooter after the test?

After the electric scooter's IPX5 waterproof test is completed, whether it can be used immediately and how long you need to wait before using it depends on multiple factors, including drying after the test, equipment status inspection, and safety considerations. Here are some specific suggestions:

1. Check the equipment status
After the test is over, the electric scooter needs to be fully inspected to ensure that it has not been damaged during the test. The inspection includes:
Appearance inspection: Check whether the outer shell is obviously damaged or deformed.
Internal inspection: Open the device shell (if possible) and check whether the internal components have water intrusion. If water has entered, it needs to be dried immediately.
Functional inspection: Test all functions of the electric scooter, including motors, brakes, steering, lights, etc., to ensure that all functions are normal.

2. Drying
If water is found to have entered the interior of the device during the inspection, it needs to be dried. The time and method of drying depends on the degree of moisture of the device:
Natural drying: Place the electric scooter in a well-ventilated place to dry naturally. It usually takes about 24 hours, depending on the ambient humidity and temperature.
Forced drying: If conditions permit, you can use a fan or hair dryer (be careful not to use high temperature mode to avoid damaging the device) to speed up the drying process. The time for forced drying is usually about 1-2 hours.

3. Waiting time
If it is confirmed after inspection that the device has not been flooded and functions normally, it can theoretically be used immediately. However, in order to ensure safety and device reliability, it is recommended to wait for a while to allow the device to dry and stabilize naturally. The generally recommended waiting time is 1-2 hours, and the specific time may be adjusted according to the following factors:
Ambient humidity and temperature: In a dry, warm environment, the device dries faster; in a humid, cold environment, the drying time may take longer.
Device complexity: If the structure of the electric scooter is more complex and has more internal components, it may take longer to ensure that all parts are completely dry.

4. Safety recommendations
Inspection before first use: Before use, check the appearance and function of the device again to ensure that there are no missed problems.
Avoid humid environments: Within 24 hours after the test, try to avoid using the electric scooter on wet or flooded roads to reduce the risk of water ingress again.
Regular maintenance: Check the waterproof seals of the electric scooter regularly to ensure that it remains waterproof during daily use.

Summary
If the device is checked and there is no water ingress: it can be used immediately, but it is recommended to wait 1-2 hours for the device to dry and stabilize naturally.
If the device is flooded: it needs to be dried, usually it takes about 24 hours of natural drying or 1-2 hours of forced drying until the device is completely dry and functional before use.
By following these steps and suggestions, you can ensure that the electric scooter can be used safely and reliably after the waterproof test.
