Factory Mutual certifies products and assemblies for the purpose of approval for Factory Mutual insured properties. Their 3-volume approval guide contains listings of 1) building materials, 2) fire protection equipment and products, and 3) electrical equipment. Although Factory Mutual conducts its approval process for its own purposes only (loss prevention for its insured properties), FM listings are commonly cited as evidence of performance for other types of projects.

SpecLink does not reference the FM Approval Guide itself, but instead offers the option of requiring products to be FM approved, if appropriate.
