GB/T 25119-2010 Railway applications—Electronic equipments used on rail vehicles
Basic Information
Scope
This standard specifies the requirements for the use, design, manufacture, and testing of electronic devices, as well as the basic software and hardware requirements necessary for their durability and reliability. If appropriate, additional requirements in other standards or specifications can be used as supplementary requirements of this standard. The terms of this standard that can be agreed upon by both parties are described in Appendix B.
This standard applies to all electronic devices installed on rail transit vehicles (including metros and urban rail vehicles) for control, regulation, protection, and power supply. These devices may be powered by on-board batteries or generators, or by low-voltage power sources (transformers, voltage dividers, auxiliary power supplies) directly or indirectly connected to the overhead contact network. In this standard, electronic devices refer to devices mainly composed of semiconductor devices and other general components, which are typically mounted on printed circuit boards.
Note: This standard also applies to sensors (for current, voltage, speed, etc.) and trigger boards for power electronic devices, but complete trigger devices should comply with GB/T 25122.1.
This standard does not apply to power electronic devices for main circuits and auxiliary circuits.
