If a sample size of 50-year standard response sprinklers is sent off for testing and passed in 2020, what year would they need to be tested again?

The correct answer indicates that after passing the initial test in 2020, the 50-year standard response sprinklers would need to undergo their next test in 2030. This aligns with the requirement that products like sprinklers need to be re-evaluated every 10 years after they’ve been initially tested.

In this case, since the sprinklers were tested and passed in 2020, the logical schedule for their next testing would be 10 years after that initial test. Thus, the next test date would indeed be 2030, complying with the standard practice ensuring ongoing reliability and safety of the equipment over time.
