• Background of the project:
  Rail transit is not only the most efficient and environmentally friendly means of transportation for the general public, but also one of the national business cards representing the advanced nature of China’s rail transit technology. The environmental protection requirements and safety of the rail transit industry are also increasingly strict.
  Main environmental protection requirements for rail transit in China:
  Tie General Technology [2014] No. 50 "Interim Technical Conditions for 350km/h China Standard EMU"

  Rail transit flame retardant testing service:
  The main cause of fire accidents in rail vehicles is that the decorative parts and electrical components inside and outside the vehicle, such as wallboard, floor, cable and other materials contain a variety of combustible components. The large number of casualties caused by fire accidents is mainly due to the fact that these combustibles release a large amount of smoke and toxic gases while burning, so that passengers can not find a way out of escape and suffocate and die.
  If the fire protection performance of the decorative materials selected on the vehicle is high, the fire will not spread rapidly, giving passengers more escape time, and the number of casualties and property losses will be greatly reduced.

  ●Large flame burning test, non-ground material, DIN54837
  ● Floor material burning test, DIN4102-14
  ●Material combustion smoke test, ENISO 5659-2
  Rail transit oil inspection service:
  High-quality fuel can provide greater efficiency for vehicles; in addition to reducing the energy consumption of vehicles, lubricants can also perform well in cooling, sealing and corrosion protection; and in order to cope with the more complex challenges faced by new models, More and more fuel additives that enhance the antiknock, anti-oxidation, anti-static and anti-rust properties of fuels have entered the field of vision.
  Rail transit material inspection services:
  Performance testing of production and incoming quality control of metal materials and components, polymer materials and components, PCB/PCBA and electronic components in the supply chain, including compositional analysis, mechanical properties, thermal properties, electrical properties, physics Performance, chemical properties and microstruct analysis.
