Overview
IEC 63005-2:2019 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies test methods for evaluating the performance of basic functions of Event Video Data Recorders (EVDRs) used in road vehicles. As a part of the IEC 63005 series, this document focuses on the essential testing procedures to ensure reliability and effectiveness of EVDRs in recording and preserving critical accident data. These devices store video and dynamic vehicle information before, during, and after collisions, assisting in accident analysis and investigation.
This standard supports the implementation of EVDRs by defining rigorous test conditions, evaluation criteria, and performance benchmarks aligned with the basic requirements outlined in IEC 63005-1:2017. By following IEC 63005-2:2019, manufacturers and testing bodies can ensure that EVDRs perform reliably under various environmental and operational conditions.
Key Topics
1. Test Environment and Setup
- Tests are performed at controlled temperatures around 23 ± 5°C.
- Simulated accident events are created using acceleration-generating equipment capable of replicating realistic collision forces ranging from 0.5 g up to 3 g for specific durations.
- The equipment must generate triangular acceleration waveforms to emulate the dynamic forces during impacts.
2. Performance Evaluation Criteria
- Power component performance: Tests include overvoltage resilience, protection during power failure, and prevention of complete battery discharge for continuously recording EVDRs.
- Vehicle dynamics data accuracy: Verification of precise recording of acceleration, angular velocity, and collision-related parameters.
- Video camera functions: Assessment of basic camera performance, including field of view (FOV), image resolution, and ability to identify critical features such as registration plates.
- Data storage and cybersecurity: Ensuring data preservation, integrity checks (including integrity verification values), and resistance to tampering or loss.
- Environmental reliability: EVDRs undergo low and high temperature operation tests, vibration, mechanical shocks, and storage condition tests to confirm durability under real-world automotive environments.
3. Test Methodology and Order
- The standard prescribes a structured sequence of tests and specific number of EVDR specimens required to guarantee consistent and repeatable outcomes.
- Simulation of multiple collision events allows evaluation of the device's ability to store sequential impacts without data loss or corruption.
Applications
IEC 63005-2:2019 is crucial for automotive manufacturers, EVDR developers, testing laboratories, and regulatory bodies aiming to:
- Ensure the functional reliability of EVDRs, which play a significant role in accident investigation and legal evidence collection.
- Validate that EVDRs comply with international performance criteria for video data quality, sensor accuracy, and robust data storage.
- Support vehicle safety enhancements by providing trustworthy data capturing devices that aid in reconstructing accident scenarios.
- Facilitate global standardization and interoperability for EVDR devices across different markets and jurisdictions.
This standard benefits road safety initiatives by advancing technologies that provide transparent accident data, enhancing driver accountability, and promoting the development of intelligent transport systems.
