Overview
ISO 10605:2023 - Road vehicles - Test methods for electrical disturbances from electrostatic discharge - defines standardized ESD (electrostatic discharge) test methods for evaluating electronic modules and complete vehicles. The standard covers ESD scenarios occurring during assembly, by service staff, and from vehicle occupants. It applies to all road vehicles regardless of propulsion (ICE or electric) and to a wide range of devices under test (DUTs): powered by unshielded or shielded power systems, self-powered modules, etc. Pyrotechnic modules are excluded.
Key topics and technical requirements
- Discharge modes: Defines and distinguishes contact discharge and air discharge techniques for reproducing real‑world ESD events.
- Test configurations: Procedures for both bench/component testing (powered-up immunity and unpowered packaging/handling) and complete vehicle testing.
- Test apparatus & instrumentation: Requirements and guidance for ESD generators, discharge tips, ground plane (GP), field coupling plane (FCP), insulating blocks, and dissipative mats.
- Direct vs indirect discharge: Methods for applying energy directly to DUTs and indirectly via coupling fixtures or vehicle structures.
- Test planning and reporting: Specified test plans, minimum discharge counts, timing between discharges, and required test report content to document behavior and pass/fail criteria.
- Verification and annexes: Normative and informative annexes include generator current target verification, standard target drawings, Function Performance Status Classification (FPSC), guidance on generator resistor selection and air/contact verification, field coupling fixture design, and automated ESD testing.
- Notable updates in 2023 edition: introduction of alternative FCP test set-up, reduction of minimum indirect discharges on components from 50 to 10, and change of interval between indirect discharges to 1 s (from 50 ms), among other clarifications.
Practical applications and who uses ISO 10605:2023
- Automotive OEMs and Tier‑1 suppliers: Validate module immunity to occupant‑ and service‑related ESD events during design validation and production release.
- EMC/ESD test laboratories: Implement standardized bench and vehicle ESD test procedures for customer testing and certification.
- Design and hardware engineers: Use results to harden circuits, connectors, and PCB layouts against ESD-related failures.
- Quality, reliability, and compliance teams: Incorporate ISO 10605 test evidence into conformity assessments and supplier quality audits.
- Maintenance and service organizations: Understand ESD risks and handling requirements for modules during repair and assembly.
