Why are “Labeled and Listed" Signs Critical to You?

Virtually ALL cities, as well as the State of Texas, adopt the National Electric Code as law.

The National Electric Code (NEC) requires that for electrical, structural, and installation safety all electrical signs be "Labeled and Listed" (tested and labelled with an appropriate Listing Mark.) (Article 600.3)

Certification (testing and labeling) organizations acceptable in the USA to test to the multitude of Standards signs are required to meet are determined by OSHA.

For you the Listing Mark is insurance.  It means that the sign has been tested to insure that it is structurally and electrically safe, and will be installed properly.  You benefit from the knowledge that it is not solely us telling you that our signs are safe, this is what the testing laboratories and the US Government says also.  Listing also means that there was a reliable source of tested replacement parts (when the sign was manufactured.)

Will your sign be tested and approved for safe use in a Wet (Outdoor) location?  Not if it’s not Listed!

Underwriters Laboratories (“UL” Listing Mark) and Intertek (“ETL” Listing Mark – originally Edison Testing Laboratory founded by Thomas Edison) are the premier certification organizations and 80% of all things electrical are tested by them.  A third testing laboratory, Eurofins ("MET" Listing Mark) also has facilities in Texas.

If the sign you are purchasing does not have a ETL, UL, or MET Listing Mark label the sign is probably not legal to install, anywhere in Texas.   There are a few local city ordinance exceptions.

Buy carefully.

Intertek is over twice the size of UL, and has a greater global presence.  UL is the largest in the USA.  We have both companies test and apply Listing Marks to various signs.

Whether it's channel letters, a wall cabinet sign, a monument sign, pole or pylon signs, electronic message centers, video displays, neon or other electric signs Intertek and Underwriter’s Laboratory pose the toughest design, structural, electrical, and installation standards on the products they approve.

We are the 9th oldest UL Listed Manufacturer in North Texas.  (File #UXYT.E149959)

To see if a manufacturer is a UL Listed sign manufacturer go to ul.com and under "Looking for UL Certified Products?" click "Visit UL Product iQ today."  Register for free, then enter "UXYT" in the "Search" box for lighted signs, or "UYFS" for electronic signs.

There are many sign companies that pretend to be Listed, but are not!

Not all of our production is Listed; some specialty signs custom manufactured for clients are not able to be Listed because of their design, however most are.

Incidentally, ISO (International Organization of Standardization) Standards, such as ISO 9001, are NOT electrical Listings (similar to a UL or ETL Listing) that allow a sign to be installed in Texas.  That said, components in our electronic signs also meet ISO 9001, ISO 9001, ISO 14001, and RoHS standards.

Underwriter’s Laboratory, Eurofins, and Intertek do NOT judge the appearance, appeal, or the longevity of a product.  This is why our many years of experience serving international, national, regional and local customers, and our investment so that we can apply the knowledge we’ve gained, will give you a superior product which will impress your customers for years to come.
