What type of organization is Underwriters Laboratories (UL)?

Underwriters Laboratories (UL) is recognized as a not-for-profit product safety testing organization. This designation reflects its mission to promote safe living and working environments through the application of safety science. UL conducts various tests and evaluations on products to determine their safety and compliance with specific standards.

Being a not-for-profit organization allows UL to focus primarily on safeguarding public interests rather than generating profit. Its role extends beyond just testing; it encompasses research, education, and the development of safety standards that enhance consumer protection. Therefore, when considering the nature of UL's operations and its commitment to safety, the identification as a not-for-profit aligns perfectly with its foundational goals and activities.

The other options do not accurately describe UL's nature: it is not a governmental agency, nor does it function as a for-profit entity or a research institution in the traditional sense.
