Brian, the confusion and what we're all "used to" likely stems from major HPR carriers requiring galv for dry and preaction systems over and above the minimum concensus standards. So #13 does NOT require the use of galv pipe in dry and preaction, but FM Global and others will for their insured. I'd imagine we're not the only contractor to also make it our std operating procedure to use galv for these, too- you often end up using galv on a dry to get the C=120 back and make the calcs work. Where it may not matter, and if we know $ are critical, we will explain we would recommend galv but if they want black, they can have it. I ask deelopers if this is something they intend to lease out and then flip, or will they pass it along to their kids as part of the family portfolio.

Therefore 8.4.7.2.1 is only applying to sections with CMSA sprinklers. Is that what you are looking for??
