Road vehicles — Controller area network (CAN) conformance test plan — Part 2: High-speed medium access unit — Conformance test plan
This document specifies the conformance test plan for the CAN physical layer as standardized in ISO 11898‑2:2016. It specifies static and dynamic tests. The dynamic tests includes the test cases for the partly implemented Classical CAN protocol and CAN FD protocol as standardized in ISO 11898‑1:2015. The static tests describe the data to be given in datasheets.
