I'm looking for the area in the IBC which 'allows' the use of other approved national standards. I have a spec that calls out the IBC and provides the site criteria (wind design criteria, seismic design criteria, ...) A vendor is supplying an AWWA steel tank including foundation. I thought I remembered a section of the code that said that directed you to the industry specific codes when applicable.
Anyone have an idea where this exists in the code?
