Overview
ISO 13140:2025 - Electronic fee collection - Evaluation of on-board and roadside equipment for conformity to ISO 13141 defines a standardized test suite structure (TSS) and the set of test purposes (TP) to evaluate on‑board equipment (OBE) and roadside equipment (RSE) for conformity to ISO 13141. The document focuses on conformance testing for Dedicated Short‑Range Communication (DSRC) used for Localization Augmentation Communication (LAC) to ensure interoperability across equipment from different manufacturers. Tests target the LAC interface level; internal functional behaviour of OBE/RSE is outside the scope.
Key technical topics and requirements
- Test Suite Structure (TSS): Organized by protocol layers (Physical, DLC/MAC/LLC, Application) and by Device Under Test (OBE, RSE). Subgroups cover valid (BV) and invalid (BI) behaviour tests.
- Test Purposes (TP): Each TP has a unique identifier and formal elements (title, reference, origin, initial conditions, stimulus and expected behaviour). Naming convention: TP///–.
- Reference and Derived Tests: The standard reuses, references or derives test cases from related base standards; where necessary it provides specific TPs for LAC application-level requirements.
- Conformance Documentation: Conformity Assessment Bodies must produce a Protocol Conformance Test Report (PCTR) for OBE (Annex C) and RSE (Annex D). The PCTR supports manufacturer declarations of conformity and type approval.
- Laboratory Requirements: Physical layer tests are performed in a radio‑wave laboratory to control RF conditions and verify DSRC characteristics.
- Terminology & Metadata: Uses harmonized vocabulary from ISO/TS 17573-2 and references other normative documents for country codes, numbering/data structures and DSRC profiles.
Practical applications and who uses it
- Manufacturers of OBE and RSE: to design and validate DSRC LAC interfaces and demonstrate conformance for market access.
- Conformity assessment bodies and test laboratories: to execute standardized conformance test campaigns, prepare PCTRs, and support type approval processes.
- Toll operators and ITS integrators: to verify interoperability of multi‑vendor equipment in electronic fee collection (EFC) systems.
- Regulators and certification bodies: to define acceptance criteria and ensure cross‑border interoperability of tolling infrastructure.
