What is CNMZTIND telling you about the IP69K of the vehicle car camera?
Vehicle cameras are an important part of vehicle video surveillance systems. In-vehicle cameras have become indispensable to automotive safety assistance system products. Vehicle-mounted cameras are installed on vehicles and are subject to long-term exposure to sunlight, rain, dust, etc., causing problems such as water seepage, dust, and fogging inside the camera, resulting in damage to the vehicle-mounted camera. Therefore, when producing a car camera, the waterproof and dustproof functions of the camera must be considered. Doing waterproof and dustproof protection for the car camera can improve the safety performance and protect the vehicle during the driving process.
IP69K is an ISO 20653 protection class for electrical equipment in road vehicles, which protects electrical equipment from the ingress of foreign objects such as water, dust and air. The IP69K rating is shown. It is a very high level of protection for vehicle electrical equipment.
IP69K tests mainly include
1. high temperature and high-pressure water scouring test (IPX9K)
2. dust tight test (IP6X)
High temperature and high-pressure water washout test (IPX9K)
Environmental conditions:
Temperature: 24.0 degrees Celsius Humidity: 56%RH
Reference: ISO20653:2013
Test Conditions:
Water temperature value: RT~80±5℃
Water pressure value: 8000~10000kPa
Water flow: 14～16L/min
Water spray distance: about 10cm ～15cm;
Water spray ring angle: 0°, 30°, 60°, 90°
Number of spray holes: 4
Test time: 30s (time can be set), 4 angles total 120s
Sample stage speed: 5±1r/min
Test equipment: waterproof test system
Test results: disassemble the sample to check that there is no water seepage or water inflow, and the sample function is normal, that is, it is qualified. as the picture shows
Dust Tight test (IP6X)
Environmental conditions:
Temperature: 22.5 degrees Celsius Humidity: 59%RH
Reference: ISO20653:2013
Test Conditions:
1. Hazardous parts protection test
A test probe with a diameter of 1 mm is pushed into any joint gap of the sample with a force of 1 Newton.
2. Solid foreign body protection test
1) Dust Type: Arizona Dust
2) Temperature range: RT+10℃～60℃ (heating and baking dust system);
3) Dust content of dust tester: 2KG/m³
4) Air velocity: no more than 2m/s
5) Dust specification: 50um～75um
6) Vibration time: 6 seconds;
7) Dust blowing time: 6 seconds;
8) Test time: A blows dust for 6 seconds, B, stops for 15 minutes. A+B is a cycle, a total of 20 cycles.
Test equipment: dust laboratory
Test results: disassemble the sample to check that no dust enters the interior, and the sample function is normal, that is, it is qualified. as the picture shows
There are many versions of IP69K waterproof testing. This method is the most stringent and the most difficult to pass. The reason why we choose such testing is entirely out of our trust in product performance and our responsible attitude towards dealers and consumers.
