GB/T 25119-2021Railway applications - Electronic equipment used on rolling stock (English PDF)

1 Scope

This document specifies the requirements for the use, design, manufacture and testing of electronic devices installed on rolling stock in rail transit, as well as the device resistance

Basic software and hardware requirements for longevity and reliability: Additional requirements in other standards or specifications may supplement this document as appropriate charge requirements: The terms of this document that the parties may negotiate and agree upon are set out in Appendix A:

This document applies to all control, regulation, protection, diagnosis, power supply and other electronic devices installed on rolling stock:

The device can be powered by the battery or generator on the vehicle, or by the low-voltage power supply (transformer, voltage divider, auxiliary power supply) directly or indirectly connected to the catenary:

source) power supply:

The special requirements required to ensure the functional safety level in practical applications are specified in 4:6:3:1, 4:6:3:2 and 4:6:3:2 of GB/T 21562-2008:

Appendix A OK:

Consider Software Safety Integrity Level 1 when residual risk remains and needs to be performed by a software-driven programmable electronic system or higher, see GB/T 28808-2021:

In this document, electronic devices (hereinafter referred to as "devices") refer to devices mainly composed of semiconductor devices and other general-purpose components:

These components are usually mounted on printed boards:

Note: This document also applies to sensors (such as current, voltage, speed, etc:) and power electronic device trigger board, see GB/T 25122:1 for complete sets of trigger devices:
