What is UL or FM?

UL (Underwriters Laboratories) and FM (Factory Mutual) are third-party testing agencies that certify and list products for their compliance with safety standards.

Manufacturers of fire protection equipment, such as fire pumps, must comply with the standard set by National Fire Protection Association (NFPA) and get the product tested and certified by UL or FM to be able to use the product in a building and to be in compliance with local codes and regulations.

UL and FM are both well-known global agencies that certify and list products for their compliance with safety standards. However, they are not two in the same.

FM specializes in providing insurance, while UL focuses primarily on product testing. FM is particularly well-known for its expertise in the firefighting and fire protection field, while UL also has a presence in the consumer electronics market in addition to firefighting equipment and fire protection products.

As a result, fire equipment and fire protection products typically require certification from both agencies, unless it is not applicable.
