Which term denotes the expectation that sprinklers activate and distribute water as intended?

Explanation:
The main idea is that a sprinkler system is expected to operate exactly as designed during testing, delivering activation and proper water distribution. When the system performs in line with the design criteria under test—sprinklers activate and water is discharged where and how it’s intended—this is described as satisfactory performance. It reflects that the performance meets the criteria for activation, flow, and distribution required by the design, with no obstructions and adequate pressure to protected areas. Data from testing is known as test results, but that term is just the measurements taken during testing, not the overarching expectation of how the system should function in service. Listing limitations refer to constraints attached to a listed component, not to how the system is expected to perform. Special sprinklers are specific types of sprinklers for particular conditions, not the general measure of expected operation.
