Overview
ISO 13143-1:2020 - "Electronic fee collection - Evaluation of on‑board and roadside equipment for conformity to ISO 12813 - Part 1" defines the test suite structure (TSS) and test purposes (TPs) used to evaluate Dedicated Short‑Range Communication (DSRC) on‑board equipment (OBE) and roadside equipment (RSE) for conformance to ISO 12813. The standard establishes a repeatable, interoperable basis for conformance testing of the Compliance Check Communication (CCC) interface between OBE and RSE. It explicitly does not cover internal functional behaviour of OBE/RSE; functional tests remain outside its scope.
Key topics and technical requirements
- Test suite structure (TSS): Organizes tests into groups (Physical, Data Link Control, MAC/LLC, Application layer) and indicates which apply to OBE and/or RSE.
- Behavior categories: Tests are classified as BV (behaviour valid) and BI (behaviour invalid) to verify correct and incorrect protocol behaviour.
- Test purposes (TPs): Each TP includes ID, title, reference, origin (identical/derived/specific), initial conditions, stimulus and expected behaviour. TP IDs follow the convention: TP///-.
- Conformance reporting: Annexes provide proforma reports (protocol conformance test report for OBE/RSE) to standardize test results and support type approval and certification.
- Test scope boundaries: Physical layer radio tests are to be performed in a radio wave laboratory and are excluded from the abstract test suite (ATS); application‑level functional behaviour of devices is outside the document’s scope.
- Traceability to base standards: The TPs reference and, where appropriate, derive or adapt test cases from related base standards (e.g., ISO 12813, ISO 14906, EN/ETSI DSRC specifications).
Practical applications and intended users
ISO 13143-1:2020 is practical for:
- Manufacturers of OBE and RSE preparing devices for interoperability and type approval.
- Conformance test laboratories and certification bodies conducting standardized DSRC CCC conformance tests.
- ITS integrators and system architects validating multi‑vendor interoperability in electronic fee collection (EFC) deployments.
- Regulators and tolling authorities specifying compliance criteria for procurement and acceptance testing.
Benefits include consistent test definitions, comparability of test results across locations, and facilitation of multi‑vendor interoperability.
