Ask Lewis Bass: A Question About Evaluating CE Marked Equipment

Welcome to another blog in our ongoing series, Ask Lewis Bass!

This series features actual submitted questions from companies in the industries we provide engineering safety consulting services to.

Topics covered include those associated with our work in 3rd party field labeling, SEMI S2/S8/EMC/F47 testing and design, CE Marking evaluations, and general engineering safety consulting questions.


Hi Lewis Bass,

What is the proper process for an inspection request if a piece of equipment is CE certified?

Does it need a UL inspection or is it considered unlisted equipment and in need of a field label evaluation?

Asked by Heidi in Moscow, ID


Lewis Bass:

Hello Heidi,

Thanks for reaching out to Lewis Bass with your question.

Anytime a piece of equipment has a CE Marking on it and is intended for use in North America it is considered unlisted equipment.

All unlisted equipment requires a third party field label to ensure the machine confirms to local electrical regulations.

On the other hand, a UL evaluation (sometimes called an LPC certification) is a formal process for evaluating equipment from the factory in small, identical batches for shipment and immediate use in any location. Equipment certified in this way is “good to go” wherever it is installed and requires no further third party electrical evaluations.

I hope this helped bring clarity to your situation!
