EMC Testing
We provide EMC testing services on various rail transit electronic products.
Service Introduction
With the increasingly electrification and intellectualization of rail transit, more and more electronic products are applied to the subway, inter-city traffic and EMU, and because the electro-magnetic compatibility of these electronic components plays an important role in the safety and reliability of vehicles, which is strictly controlled by governments and main engine factories. The main engine factories will not adopt the electronic products failing the EMC test. 

Product Scope: 

EMC of whole rail transit vehicles, rail transit components, rail transit electromagnetic environment. 
It includes most EMU electronic components, such as standard EMU vacuum dejectas collector, sensor, vehicle lamp, camera, on-board wireless receiving gateway, steam condensing device, refrigerator, incubator, oven, lampblack treatment system and other core kitchen equipment. 
Besides, it also covers most subway and inter-city traffic electronic components, such as subway screen door, ticket machine, security check integrated machine, cloud ticket purchase machine, passenger self-service terminal, broadcasting system, sensor, etc.
