JIS D4604 Fuel Tank Integrity Crash Test
The Japanese Industrial Standard (JIS) D4604 fuel tank integrity crash test is a critical component in automotive safety. This test evaluates the structural integrity of fuel tanks under simulated high-impact conditions, ensuring they can withstand collisions and prevent fuel leakage. The standard aims to enhance passenger safety by reducing the risk of fire or explosion resulting from fuel leaks during vehicle accidents.
The test involves simulating a front-end collision using a test rig that strikes the fuel tank at an angle similar to real-world crash scenarios. The specimen fuel tank is subjected to a predetermined impact energy, typically ranging from 20 to 35 kJ, depending on the vehicle's weight class. This ensures that the test accurately reflects the forces encountered in actual collisions.
The primary objective of this test is to determine whether the fuel tank can retain its contents without leaking under specified crash conditions. Compliance with JIS D4604 ensures that vehicles meet regulatory requirements and enhance consumer confidence.
Scope and Methodology
| Test Parameters | Values |
|---|---|
| Impact Energy Range | 20 to 35 kJ |
| Collision Angle | 45° ± 1° to the longitudinal axis of the vehicle |
| Test Specimen | New or reconditioned fuel tank, depending on the test purpose |
| Testing Environment | Temperature: 23°C ± 5°C; Humidity: 40% to 60% |
The test rig is calibrated and validated before each series of tests. The fuel tank is mounted securely on the rig, ensuring that it replicates the vehicle's structure as closely as possible. The specimen undergoes a series of inspections prior to testing, including visual checks for any pre-existing damage or flaws.
