BAIJIAN - Third party testing organization
The GB/T2519-2010 standard for electronic devices on locomotives and rolling stock is mainly applicable to electronic devices installed on rail transit vehicles、 such as control、 regulation、 protection、 or power supply. This standard also applies to current and voltage sensors or trigger boards for power electronic devices
The G25119-2010 type test mainly involves seven aspects: climate environment test、 mechanical environment test、 electromagnetic compatibility EMC、 performance test、 insulation resistance withstand voltage safety regulation test、 shell protection level test、 and reliability environmental stress screening test.
The specific inspection items for the G25119-2010 type test of locomotive and vehicle electronic devices include:
1. Climate environment test: low temperature test、 high temperature test、 low temperature storage test、 alternating damp heat test、 salt spray test、 etc
2. Mechanical environment tests: functional vibration test、 long-life vibration test、 mechanical impact test、 etc
3. Electromagnetic compatibility EMC: electrostatic discharge test、 radiation immunity test、 pulse group test、 surge test、 conducted immunity test、 conducted disturbance test、 radiation disturbance test、 etc
4. Safety test: insulation resistance at room temperature、 voltage withstand test at room temperature、 insulation resistance after damp heat、 voltage withstand test after damp heat、 etc
5. IP protection level test: IP54、 IP55、 IP65、 IP66、 IP67 levels
6. Reliability test: temperature cycling test、 stress screening rapid temperature change test+random vibration test、 etc
7. Performance tests: appearance inspection、 power outage test、 power fluctuation test、 overvoltage test、 etc
