Let's go back to George's original post. I read something about the shape or size of the nail plate was not up to the liking of the inspector. As far as I know there are no nail plate requirements that talk about size and shape in 13, 13R or 13D. Thus an AHJ might look else where for guidance. It would be totally appropriate for an AHJ to use a code like the IMC or IPC if they have specific guidance on such matters.
Let's say 13, 13R, 13D and the listing for plastic sprinkler pipe don't say how thick a nail plate must be but the IPC does. AHJ is on solid legal ground to enforce the minimum thickness of the IPC. So George got some more specifics? Then we can determine if it's something not covered by our family. Chris Cahill, P.E.
