Railway

MET Labs has the equipment, accreditations and experience to ensure your railway components and systems are safe, reliable, and electromagnetically compatible (EMC).

Services we provide include:

  • Product evaluation and creation of appropriate test plans
  • Product testing and certification at component and system level in the lab or field
  • Conducting on-site EMI field surveys or safety field evaluations
  • Environmental simulation: Weathering effects, aging, vibration, solar and reliability testing
  • Consulting and debug

Our EMC Testing Capabilities

Customers can choose from convenient 10, 5, or 3-meter anechoic and semi-anechoic laboratories throughout the U.S. We can accommodate small signaling equipment to whole locomotives. Our capabilities enable us to test to the highest levels required by the EN50121 series of standards.

Where products are too physically large to be assessed in a test chamber, we can test in situ.Our mobile team with specialized field equipment can test at your location – indoors or outdoors – throughout North America.
