Compliance Testing Center and Anechoic Chamber


The testing capabilities of LECO’s Compliance Testing Center ensures that LECO instruments are compliant to worldwide product safety and Electromagnetic Compatibility (EMC) requirements. EMC testing includes radiated and conducted emissions, electrostatic discharge, power line transients, near lightning strike surges, RF conducted immunity, and many other testing capabilities. Testing is also performed to ensure LECO instruments are safe from shock hazards, high temperatures, moving parts, etc. 

The ability to test on-location during all phases of product development allows LECO to guarantee compliance with all requirements for worldwide sales, including the CE requirements in Europe. 

Our Compliance Testing Center provides Declaration of Conformity certificates for instruments tested at our facility upon request. To request a certificate, click here.
