UL is the certifying agency for product safety in the United States of America. The Underwriters Laboratories (UL) test products worldwide according to corresponding U.S. product safety requirements, so that these products may be marketed and sold in every part of the United States of America and Canada.
The UL Mark is the most widely accepted proof that a product meets American and Canadian safety requirements. For North American consumers, regulators and manufacturers, the UL Mark is a recognized symbol of product safety. More than 17 billion UL Marks appear every year on new products.
If you wish the UL identification to be applied to your circuit boards, simply specify this as option within our PCB Calculator.
