Enhanced UL Marksmore
In response to evolving customer needs, we have introduced an enhanced version of our Certification Marks that will eventually replace our traditional Listing and Classification Marks. The enhanced mark utilizes a modular approach to illustrate the attributes of a product that UL has certified, and includes the manufacturer’s file number that will make it easier to identify the applications for which the product is certified.
UL Field Evaluations bridge the gap between uncertified equipment and a code compliant installation. Our skilled staff are fast, thorough and trustworthy, and our services meet the needs of both the owner and code authorities.
Architects, contractors and code authorities rely on the UL Fire Resistance Directories as the source document for their designs. Other suites of product directories and publications are also available.
UL certifications and UL Evaluation Reports provide the technical foundation relied upon by architects, designers, contractors and code authorities to provide safe, code compliant installations.
An important part of designing and building a safe, code compliant structure is specifying and utilizing equipment, materials, and assemblies that have been evaluated to nationally recognized safety standards.
