Overview
ISO/TR 17716:2025 - Road vehicles - Electrical disturbances from narrowband radiated electromagnetic energy - Radiated immunity for V2X - is a Technical Report from ISO that provides guidance for introducing radiated immunity testing to components and complete vehicles equipped with V2X (Vehicle-to-Everything) communications. It focuses on making V2X functions (DSRC and C‑V2X) operate during EMC chamber tests by simulating link connections and V2X scenarios, describing monitoring methods, and offering practical test hints. As a technical report, it provides guidance and examples rather than prescriptive technical specifications.
Key topics and recommended test considerations
- Radiated immunity testing for V2X components and vehicles
- Guidance on how to support V2X communications during narrowband radiated immunity tests.
- Link communication connection
- Practical approaches to maintain DSRC, PC5 and cellular links (LTE/NR) during EMC testing so Tx/Rx operation can be observed.
- V2X scenario simulation
- Methods to simulate realistic V2X traffic and scenario states to assess functional performance under electromagnetic stress.
- Monitoring and communication indicators
- Recommended indicators to monitor (e.g., packet error ratio, RSSI, message throughput, GNSS position quality) and examples of observed electromagnetic-interference reactions.
- Fault case examples
- Typical Rx and Tx fault behaviours for devices under test (DUT), including impacts on GNSS and cellular functions.
- Test hints and practical parameters
- Link parameters (DSRC, PC5, GNSS), link antenna location guidance, exclusion band considerations, filtering examples and monitoring setups.
- Guidance scope
- Emphasizes complex nature of vehicle-level tests and positions the document as quality-assurance guidance rather than a pass/fail standard.
Applications and intended users
ISO/TR 17716:2025 is aimed at professionals involved with automotive EMC and V2X integration:
- OEMs and Tier‑1 suppliers validating V2X modules and on‑board units (OBUs) in EMC chambers.
- EMC test laboratories developing test plans that preserve V2X communications during radiated immunity tests.
- Systems engineers responsible for automated driving and ITS feature robustness.
- Regulators, NCAP and safety assessors seeking insight into V2X immunity testing practices for safety assurance and evaluation.
- Use cases include pre‑compliance testing, root‑cause analysis of interference effects, and quality assurance of V2X-enabled vehicles and components.
