• PDPA and PIV measurements for sprinkler spray drop size and velocity

Test Standards

• UL2167, Water Mist Nozzles for Fire-Protection Service

The UL advantage

UL testing and certification services offer several advantages to both manufacturers and users of fire suppression equipment. One advantage is product listing in the appropriate UL product directory. UL directories contain a list of companies that have demonstrated compliance with UL requirements and applicable standards and are authorized to use a UL Mark. The directories are considered invaluable resources by thousands of regulatory authorities, building owners and insurance companies.

UL can also help you reduce time to market by offering efficient and flexible services from an industry leader in fire-safety certification. Because UL offers comprehensive, state-of-the-art testing facilities and a highly experienced technical staff with extensive code knowledge, the UL Mark is immediately recognized and respected by professionals in fire safety around the world.
