How often must standard response sprinklers be retested after their initial replacement?

Standard response sprinklers are required to be retested every 10 years after their initial installation or replacement. This periodic testing is essential to ensure that the sprinklers remain functional and effective in the event of a fire. The 10-year interval is established based on industry standards and best practices, recognizing that environmental factors, corrosion, and the accumulation of debris can impact the operational reliability of the sprinklers over time. Therefore, this regular retesting is crucial for maintaining safety and compliance with fire protection regulations.
