On-Site Field Evaluations

If you have failed an electrical inspection or have been told that you need to have “UL Testing”, “UL Field Evaluation”, “UL Field Inspection”, “UL Field Certification” or are in need of “UL Field Labeling”, we can help you.

Many of these terms are used interchangeably and can often create a lot of confusion.  If a city or county electrical inspector uses one of these terms, what they are really saying is that, for whatever reason, your equipment, or installation, lacks adequate marking to meet local, state or federal requirements for electrical safety.  The remedy they are suggesting is called a “Field Evaluation” or a field evaluation performed by a Nationally Recognized Testing Laboratory (NRTL Field Evaluation).

A field evaluation does not have to be performed by UL.  Since many of the electrical safety standards that have been adopted by OSHA are published by UL, people will often associate a field evaluation with UL.

The fact is, Eurofins MET Labs has been performing field evaluations for over 60 years.

Timing is crucial. The opening of a business, the start of a new production line, an exciting investment in a custom piece of equipment set to change your organization, can be unexpectedly held up by a piece of unlisted equipment.

United States Occupational Safety and Health Administration (OSHA) 29 CFR 1910.303 and 1910.399 mandate that listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling.

But what do you do if your equipment isn’t labeled?
