Full title and description

Road vehicles — FlexRay communications system — Part 5: Electrical physical layer conformance test specification. This part of ISO 17458 specifies a standardized conformance test suite and procedures to verify electrical-physical-layer compliance and interoperability for FlexRay Bus Drivers and Active Stars.

Abstract

ISO 17458-5:2013 defines the conformance test for the electrical physical layer of the FlexRay communications system, referencing ISO 9646 and ISO 17458-4. Its purpose is to provide reproducible, standardized tests to verify whether FlexRay Bus Driver and Active Star implementations conform to the electrical-layer requirements so different manufacturers’ components interoperate in system environments. The document contains technical test procedures and pass/fail criteria to ensure consistent test results across compliant test systems.

Scope

This part of ISO 17458 specifies the electrical-physical-layer conformance tests for FlexRay. It defines the test environment, stress conditions, parameter lists and a comprehensive set of test cases to verify Bus Drivers and Active Stars against the electrical-layer specification given in ISO 17458-4, using conformance-testing principles aligned with ISO 9646. The goal is to ensure interoperability of electrical-layer components in automotive FlexRay networks.

Key topics and requirements

• Definition of test environment and required test equipment and setup (for Bus Drivers and Active Stars).
• Stress conditions and parameter ranges to exercise the electrical physical layer under realistic and worst-case conditions.
• Detailed parameter lists and measurement methods for electrical signals (timing, voltages, differential signalling, bit timing, etc.).
• Comprehensive test cases grouped by device type: Bus Drivers; Active Stars (with and without communication-controller or host interfaces).
• Conformance test methodology aligned with ISO 9646 to ensure reproducibility of test results across test systems.

Typical use and users

Used by automotive OEMs, Tier‑1/Tier‑2 suppliers, silicon and module vendors, independent test laboratories, and certification bodies to validate and certify FlexRay physical-layer devices (bus drivers and active stars) and to support interoperability verification during vehicle network integration and supplier qualification. Test-system developers and tool vendors also use it to implement compliant conformance test suites.

Related standards

ISO 17458 is a multipart series for FlexRay; closely related parts include: ISO 17458-1 (General information and use case definition), ISO 17458-2 (Data link layer specification), ISO 17458-3 (Data link layer conformance test specification) and ISO 17458-4 (Electrical physical layer specification). These parts provide the protocol, API/behavioral requirements and the normative electrical specification that Part 5’s conformance tests verify.

FAQ

Q: What is this standard?

A: ISO 17458-5:2013 is the Part 5 conformance test specification for the electrical physical layer of the FlexRay communications system, providing standardized test procedures to verify compliance of Bus Drivers and Active Stars.

Q: What does it cover?

A: It covers the electrical-layer conformance test environment, stress conditions, parameter lists, detailed test cases for Bus Drivers and Active Stars (including variants with controller or host interfaces), and the pass/fail criteria needed to demonstrate conformity with ISO 17458-4.

Q: Who typically uses it?

A: Automotive OEMs, component and module suppliers, semiconductor vendors, independent test labs, certification bodies and test-tool vendors use it for device validation, supplier qualification and interoperability testing.

Q: Is it current or superseded?

A: The published edition is ISO 17458-5:2013 (Edition 1). The ISO record lists the document as published/confirmed; users should check ISO or national standards bodies for any updates or revisions after 2013 before relying on it for new procurement or compliance activities.

Q: Is it part of a series?

A: Yes — ISO 17458 is a multipart FlexRay series (Parts 1–5 at least), where Part 1 gives general information and use cases, Part 2 defines the data‑link layer, Part 3 specifies data‑link conformance tests, Part 4 defines the electrical physical specification, and Part 5 provides the electrical physical conformance tests.
