Cast-Iron Soil Piping
2.1.1.1
Cast-Iron Hub and Spigot Soil Pipe and Fittings
ASTM A 74, [service] [extra heavy], with ASTM C 564 compression-type rubber
gaskets.
2.1.1.2
Cast-Iron Hubless Soil Pipe and Fittings
**************************************************************************
NOTE: Delete this paragraph for areas where hubless
fittings are considered inappropriate due to failure
of coupling by corrosion.

Clay Piping
2.1.2.1
Clay Pipe and Fittings
**************************************************************************
NOTE: Tables of trench loadings, trench backfill
loads, and supporting strengths of clay pipe are
included in the Clay Pipe Engineering Manual (1982
edition) of the National Clay Pipe Institute. The
required strength of clay pipe can be derived from
these tables when depth of trench is known.
Specify "bell-and-spigot piping only" in areas where
corrosion problems may be anticipated with the
stainless steel parts of the couplings used for
plain-end piping.
