Underwriters Laboratories, Inc. (UL) is the leading third party
product safety organization in the United States, the largest in North America and
the leading quality system registrar headquartered in the United States. Providing
product safety verification services for more than a century, the UL Mark is one
of the world’s most familiar safety certification symbols.
The UL Marks, Listed and
Recognized assure compliance to a verifiable
set of accepted standards for safety, adding value to a defined product quality.
UL’s findings are recognized by insurance rating bureaus and many Federal,
State and local authorities.
This is accomplished through product safety and performance testing
using verifiable test data, quality system registration, harmonization and standardization
of codes and standards. UL continues to be a leader in domestic and international
code and standards development. On-going, frequent in-plant manufacturing
inspections by UL Follow Up Services keep product safety first.

joint procedures, standards and marks. The Marks for Listed
