Scope

GB/T 45503-2025 is the English-translated version of 汽车以太网电子控制单元测试规程.

GB/T 45503-2025 is the Chinese national standard covering conformance testing of an Ethernet ECU layer by layer — the physical layer measurements for 10BASE-T1S, 100BASE-T1, 1000BASE-T1, 100BASE-TX and multi-gigabit links and the interoperability runs, the MAC frame and frame check sequence tests, the ARP, IPv4, UDP and TCP conformance, the DHCP client and SOME/IP tests, the parameter configuration, and the initialization time that decides how long after a wake-up the network is usable. At 59,500 words, with the physical layer tests taking most of it. First edition, under the Ministry of Industry and Information Technology. In force from 1 November 2025. Issued on 25 April 2025, it has been in force since 1 November 2025.
