Seems this one pops up every couple of years. My take, if you modify 1 sprinkler, you are required to do a 2 hour test, and provide the Test Certificate.
The first paragraph states pressure and duration, unless permitted by 1.2 through 1.5. These sections only modify pressure. The original duration stipulated in 25.2.1.1 (16) remains unchanged.

I’d tell new inspectors to view it as more of a leak test. Not two hours. But best if water is on a little while so leakers show before cover. Best.
