Overview
EN ISO 13143:2025 - titled Electronic fee collection - Evaluation of on-board and roadside equipment for conformity to ISO 12813 - specifies the test suite structure (TSS) and test purposes (TPs) used to evaluate the conformity of Dedicated Short-Range Communication (DSRC) on-board equipment (OBE) and roadside equipment (RSE) to ISO 12813. The standard provides a harmonized basis for conformance tests that support interoperability across equipment from different manufacturers and for consistent conformance evaluation and type approval processes.
Note: ISO 12813 targets the compliance check communication (CCC) interface level - internal OBE/RSE functional behaviour is explicitly outside the scope of EN ISO 13143:2025.
Key topics and technical requirements
- Test Suite Structure (TSS): Defines how tests are organized for protocol and interface verification between OBE and RSE.
- Test Purposes (TPs): Normative test purposes for both OBE and RSE (detailed in Annex A and Annex B) that describe the objectives and expected outcomes of each conformance test.
- Conformance reporting: Includes protocol conformance test report proforma for OBE (Annex C) and RSE (Annex D) to standardize test documentation and comparability of results.
- Scope limitations: Focuses on CCC interface-level conformity to ISO 12813; does not prescribe internal device behaviour tests.
- Consistency and comparability: Enables repeatable evaluation procedures so different test labs produce comparable results over time and locations.
Practical applications
- Type approval and certification: Used by conformity assessment bodies and national regulators to validate DSRC OBE/RSE implementations against ISO 12813.
- Interoperability testing: Enables toll operators and system integrators to verify that OBE and RSE from different vendors interoperate reliably at the CCC interface.
- Test lab procedures: Provides a test suite structure and test purpose definitions for test houses and laboratories to implement standardized conformance tests and generate PCTR/SCTR reports.
- Procurement and supplier validation: Assists procurement teams in specifying acceptance test criteria for DSRC equipment.
Who should use this standard
- Equipment manufacturers (OBE/RSE vendors)
- Conformity assessment bodies and test laboratories
- Toll operators and ITS integrators
- National standards bodies and type-approval authorities
Related standards
- ISO 12813:2024 (Compliance check communication for autonomous systems)
- ISO 17573-2 (EFC vocabulary/system architecture)
- EN 15509, EN 12834, ISO 14907-2 and ETSI test specifications referenced for DSRC and EFC testing
EN ISO 13143:2025 is essential for stakeholders aiming to ensure DSRC-based electronic fee collection devices meet internationally harmonized conformance and interoperability criteria.
