Equipment, materials, or services included in a list published by an organization that is acceptable to the authority having jurisdiction and concerned with evaluation of products or services, that maintains periodic inspection of production of listed equipment or materials or periodic evaluation of services, and whose listing states that either the equipment, material, or service meets appropriate designated standards or has been tested and found suitable for a specified purpose.Ī.3.2.3 Listed. Acceptable to the authority having jurisdiction.ģ.2.3* Listed. While this shorthand is popular (including, at times, in our own products), there’s another good reason to understand the difference between “listed” and “approved:” the NFPA draws a sharp distinction between those products or installations that are listed and those that are approved.ģ.2.1* Approved. UL avoids the word as a way of indicating that it really is the manufacturer’s responsibility to ensure safety and that UL only acts as an auditor” “f you look at their website, the only mention of ‘approvals’ is in examples of incorrect terms. Manufacturers, retailers, and consumers often describe fire protection products as “UL-listed,” “FM-approval,” and even “UL and FM approved.” But as Bruce Rose at CUI Insights notes, there’s really no such thing as “UL-approved”-and for good reason. UL listed and FM approval act as industry synonyms for “listed” or “certified”-but the different terms have distinct definitions under NFPA codes and standards UL-listed and/or FM-approved residential and commercial fire sprinkler heads, check valves, hose angle valves, CPVC pipe, pipe hangers, and fire extinguishers are just part of our vast catalog of certified equipment -just take a look. Finally, we present readers with an overview of products requiring these certifications in NFPA 13 : Standard for the Installation of Sprinkler Systems. We explain what terms like these mean and who decides when a particular organization-be it UL, FM Global/Approvals, or another group-has the credibility needed to certify specific types of fire protection products. In this article, we bring some clarity to the subject of listings and approvals. But for many consumers, what remains unclear is the matter of which certifications to use and when they’re required. Fire pumps, fire sprinklers, pipes, extinguishers, and a vast array of other products regularly undergo rigorous, third-party testing according to the standards of groups like FM Global and UL (formerly known as Underwriters Laboratories). “UL listed” and “FM approval”-along with their lesser-mentioned cousin, “certified”-are terms that circulate freely in the world of fire protection. NFPA 13 BAFFLE CODEListings are required for all essential system components but acceptance of specific approvals-UL listed, FM approved, or otherwise-is determined by local code officials
