ISO 16407-1:2017

Overview

ISO 16407-1:2017 - "Electronic fee collection - Evaluation of equipment for conformity to ISO 17575-1 - Part 1: Test suite structure and test purposes" defines a structured conformance test suite for Electronic Fee Collection (EFC) systems. It specifies test purposes (TPs) to assess Front End (on-board equipment and optional proxy) and Back End behaviour against the structural and semantic requirements in ISO 17575-1:2016 (Charging). The standard provides test-suite structure, TP naming/definition conventions, required initial conditions, references and expected behaviour in a textual, machine-readable-friendly format.

Key topics and technical requirements

• Test suite structure (TSS): organized groups for Front End and Back End behaviours - e.g., Charge Report (Front End), Back End feedback (Front End), Charge Report Response (Back End).
• Test purposes (TPs): detailed descriptions in Annex A (Front End) and Annex B (Back End) that list:
  • TP ID and naming conventions
  • Title and reference to the clause/requirement in ISO 17575‑1
  • TP origin (identical/derived/specific)
  • Initial conditions
  • Stimulus and expected behaviour
• Data structures and semantics: Annex C defines the data structures used by TPs and maps to ISO 17575-1 data groups (General, Security, Contract, Usage, Account, Versioning).
• Proforma Conformance Test Reports (PCTR): templates provided in Annex D (Front End) and Annex E (Back End) for consistent reporting of conformance test results.
• Standards and methodology: built on ISO 17575-1 and conformant with ISO/IEC 9646 conformance test methodology; abbreviations include TTCN, ATS, PICS, GNSS, CN, OBE.
• Scope exclusions: dynamic behaviour (message sequences), business-profile-specific logic, and Behaviour Invalid (BI) tests are explicitly out of scope.

Practical applications and target users

ISO 16407-1 is practical for organizations involved in designing, testing, certifying and operating GNSS/CN-based autonomous tolling systems:

• EFC equipment manufacturers (OBE, proxy) - to design implementations that meet ISO 17575‑1 semantics.
• Conformance test laboratories and certification bodies - for executing standardized TPs and producing PCTRs.
• Toll domain authorities and integrators - to verify vendor claims and ensure interoperability across Back End/Front End interfaces.
• System integrators and testing teams - to structure test plans, map requirements to test cases, and adopt TP naming/definition conventions.

Related standards

• ISO 17575-1:2016 - Application interface definition for autonomous systems (Charging) - normative reference.
• ISO/IEC 9646 - Conformance test methodology (basis for test approach).
• Additional parts of the ISO 16407 series cover further conformance aspects and complementary test specifications.
