Communication systems

The building material industry's communication systems team supports the telecommunication and information technology industries by providing certification and customized testing services.

A unique benefit to testing at UL is getting your product Listed in a UL Product Directory. The Product Directory, which contains the names of companies qualified to use a UL Mark on products that comply with UL's requirements, is an invaluable resource used to determine the correct application of a product or system.

Architects, authorities having jurisdiction (AHJs), purchasing agents and others turn to UL's Product Directories to find important information about products bearing the UL Mark. The regulatory services department is dedicated to promoting the product directories directly to appropriate officials. Acceptance of the product directories minimizes processing and construction delays.

Having your product Listed in a UL Product Directory instantly puts you in front of more than 2,500 AHJs and code officials.
