Retesting of fast response sprinklers is required at what interval?

Retesting of fast response sprinklers is required at 10-year intervals to ensure that they continue to function effectively in a fire event. Over time, components of the sprinkler system may degrade due to environmental exposure, corrosion, or other wear and tear influences. By implementing a 10-year retesting requirement, safety standards ensure that any potential reduction in performance or effectiveness of the sprinklers is identified and addressed, thereby maintaining the integrity and reliability of the fire protection system.

This interval aligns with industry standards intended to promote safety and compliance with codes. Fire protection systems, including sprinklers, need to be reliable when activated, making such intervals significant for ongoing protection strategies. Consequently, organizations and building owners must adhere to this 10-year requirement to ensure compliance and enhance safety measures in their facilities.
