Overview
ISO 13143:2025 - 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 defines how conformance testing is organised to support interoperability between equipment from different manufacturers, focusing on the Compliance Check Communication (CCC) interface level. Internal functional behaviour of OBE/RSE is explicitly outside the scope.
Key topics and technical requirements
- Test Suite Structure (TSS): Organized by protocol layers - Physical, Data Link Control (DLC) including MAC/LLC sublayers, and Application layer - with subgroups and inherited test cases from base specifications.
- Test Purposes (TPs): Each TP is defined with a unique ID, title, normative reference, origin (identical/derived/specific), initial conditions, and stimulus/expected behaviour. Naming convention: TP///- (e.g., TP/PHY/OBE/BV-01).
- Valid / Invalid Behaviour Classification: Tests are grouped as BV (behaviour valid) or BI (behaviour invalid) to verify both correct and erroneous protocol handling.
- Reference to Base Standards: TPs may be identical to, derived from, or specific relative to existing conformance tests in standards such as ETSI/TS 102 486-2-2, EN 15876, and the referenced ISO 12813:2024.
- Normative Annexes and Reports: Annex A/B contain normative TPs for OBE and RSE; Annex C/D provide protocol conformance test report proformas (PCTR) that conformity assessment bodies must complete. The PCTR supports manufacturers’ declarations of conformity.
- Laboratory Requirements: Physical layer (radio) tests shall be performed in a radio wave laboratory.
Practical applications
- Ensures interoperability of DSRC OBE and RSE in electronic fee collection (EFC) systems.
- Provides a repeatable, harmonized basis for conformance evaluation, type approval, and procurement verification of tolling equipment.
- Supports creation of test suites and automated test systems for protocol conformance at physical, link and application layers.
- Helps regulators, toll operators and certification bodies compare test results across locations and times.
Who should use this standard
- OBE and RSE manufacturers developing DSRC compliance.
- Conformity assessment bodies and test laboratories performing protocol conformance testing.
- Tolling authorities, ITS integrators, and procurement teams specifying interoperability requirements.
- Standards implementers and developers building CCC-compliant systems per ISO 12813.
