Our fire safety division’s suppression team supports manufacturers, regulatory authorities, building owners and insurance companies with certification and customized testing services for a variety of suppression equipment, including products for residential and commercial sprinkler systems.


We test and certify sprinklers and nozzles considering the requirements to the current editions of the following standards:

  • ANSI/UL 199 Standard for Safety of Automatic Sprinklers for Fire-Protection Service
  • ANSI/UL 1767 Standard for Safety of Early-Suppression Fast-Response Sprinklers
  • ANSI/UL 1626 Standard for Safety of Residential Sprinklers for Fire-Protection Service
  • ANSI/UL 2351 Standard for Spray Nozzles for Fire-Protection Service
  • EN 12259-1 Requirements and Test Methods for Sprinklers
Field sprinkler testing

Many communities have adopted NFPA 25 as a referenced standard in their building codes, which are enforced by local inspection authorities. We test sprinklers sampled from field installations as a service to inspection authorities, the sprinkler industry, the insurance industry and property owners. The test results reported from us assist these interested parties in accessing the effectiveness of sprinkler systems, or the need for replacement of sprinklers currently in service.
