Yes, Chapter 10 gives the standards for DI pipe and fittings, but apparently
Chapter 10 isn't applicable to a riser manifold or spool piece.
6.3.1.1.1* Underground pipe shall be permitted to extend
into the building through the slab or wall not more than 24 in.
(600 mm).
10.1.4.1* Underground piping shall be permitted to extend
into the building through the slab or wall not more than 24 in.
(600 mm). [24:10.1.4.1]
This may seem overly fastidious, but I work at a nuclear weapons plant where
"anal" is never mentioned because it's a given.

The DI standards for pipes and fittings are listed in Chapt 10, Underground
Piping.

Subject: RE: Ductile Iron Fittings
B16.4 is for gray iron which I think is the most common form for fire sprinkler
system above ground threaded fittings.
I'm attempting to determine the applicable standard for ductile iron flanged
fittings AND whether or not such fittings are permissible in the above ground
portion of the fire sprinkler system. Specifically in the riser manifold. It
could be a flanged ductile iron tee or flanged ductile iron spool piece, etc.
I heard that they are being used as I described. So, I thought I'd look it up
to see if NFPA 13 allowed it. And, none of the standards listed in the
acceptable materials table address ductile iron.
I'm comfortable with pointing to 1.7 as a "back up" justification. But, any
more help would be appreciated.

Scott,
Isn't 36.10M for Welded and Seamless pipe?
B16.4 is for fittings.

Thanks for all the responses.
The reason is because NFPA 13 does not include ductile iron (ASME B36.10M) in
the acceptable materials table. My opinion is that it is functionally more than
adequate.
Would this be covered by section 1.7 (2016) for alternate arrangements?
