What is TSI Power’s procedure for obtaining a NRTL (Nationally Recognized Testing Laboratory) safety listing?

We design the product to the applicable standards and work with Intertek/ETL or Underwriters Laboratories to prepare a documentation package with all safety critical components. Intertek or UL then sends a test engineer to our factory to conduct the safety tests required by the applicable standard. If all the documentation and tests meet Intertek’s standards, they will issue an Authorization to Mark (ATM).
