The upper section of the waterproof test chamber testing device is covered in this part, so I recommend that everyone read it along with the previous two articles for better understanding.
UL Test Bending Finger (PA100A Probe):
1. This probe is manufactured in accordance with the relevant provisions of UL1278, UL1026, and UL507.
2. The UL test bending finger is an essential tool used during electric shock protection tests for household and similar electrical appliances. It ensures compliance with safety standards by simulating human contact during testing.
Waterproof Test Chamber – GB/T 4942.2-1993 Standard:
This standard outlines the requirements, testing methods, inspection rules, markings, packaging, storage, and handling of parking distance warning devices. It is specifically designed for such systems used in vehicles.
It's important to note that the range warning device is not a substitute for manual parking by the driver. It is not intended to alert other people or objects within the parking area. The waterproof test equipment is only an auxiliary tool to support the driver during parking and does not relieve them of their responsibility.
This standard is not equivalent to ISO/TR 12155:1994(E), which specifies requirements and testing for obstacle detection devices on reversing commercial vehicles. It also references DIN 75031, which outlines requirements and inspections for shunting alarms on commercial vehicles and trailers.

By following these standards and using the correct testing equipment, manufacturers can ensure their products meet the necessary safety and performance criteria. Whether you're conducting UL tests or adhering to Chinese standards, proper testing procedures are crucial for product reliability and user safety.
