Underwriters Laboratories is a well-known testing laboratory that develops standards for consumer products, chiefly dealing with product safety.

A product with Underwriters Laboratories approval is said to be "UL-rated." Purchasers can identify such products by the distinctive UL Mark [1], accompanied by a serial number.

UL has ratings standards for many products, even bullet-proof vests. The average householder may be more familiar with UL-rated products such as home electrical appliances.

A moderately famous video clip shows UL researchers demonstrating the risks of certain models of deep-fat turkey fryer. This serves as a suggestion of the importance of this sort of product testing. [2]

The European analog of the UL mark is the CE logo.
