 How
to Specify Cast Iron Soil Pipe and Fittings For Your Project–CISPI
Recommended Specifications
CISPI Specifications
- CISPI 301-00
Standard Specification for hubless cast iron soil pipe and fittings
for sanitary and storm drain, waste, and vent piping applications.
(This specification is reviewed and revised every five years.
The number following 301 indicates the last year of revision.)
- CISPI 310-97
Specification for coupling for use in connection with hubless
cast iron soil pipe and fittings for sanitary and storm drain,
waste, and vent piping applications. (This specification is
reviewed and revised every five years. The number following
310 indicates the last year of revision.)
- CISPI Designation HS 74-86
Specification for cast iron soil pipe and fittings for hub and
spigot sanitary and storm drain, waste, and vent piping applications.
(This seldom-referenced specification modified ASTM A-74 by
making pressure testing optional and appropriate collective
marks optional.)
- CISPI Designation HSN 85
Specification for Neoprene rubber gaskets for hub and
spigot cast iron soil pipe and fittings. (This seldom-referenced
specification covers preformed rubber gaskets used to seal joints
in hub and spigot cast iron soil pipe and fittings. The most
common specification referenced today is ASTM C 564.)

ASTM Specifications
- ASTM A 74-98
Standard specification for cast iron soil pipe and fittings.
(This specification is reviewed and revised every five years.
The number following A 74 indicates the year of latest revision.)
- ASTM A 888-98
Standard specification for hubless cast iron soil pipe
and fittings for sanitary and storm drain, waste, and vent piping
applications. (This specification was first printed in 1991
and will be reviewed and revised every five years. The number
following A 888 indicates year of latest revision.)
- ASTM C 564-97
Standard specification for rubber gaskets for joining
cast iron soil pipe and fittings. (This specification is reviewed
and revised every five years. The number following C 564 indicates
the year of last revision.)
- ASTM A 674-95
Standard practice for polyethylene encasement for ductile
iron pipe for water or other liquids. (This specification is
updated and revised every five years. The number following A674
indicates the year of last revision. This specification and
ANSI A21.5 are referenced for external corrosion protection
for cast iron installed underground. The ASTM A 74-98 and A
888-98 contain information contained in this standard.
- ASTM C 1277-97
Standard specification for shielded couplings joining
hubless cast iron soil pipe and fittings. New standard for shielded
couplings used to join hubless cast iron pipe and fittings.
(CISPI 310 couplings meet this standard as do most heavy duty
couplings.)
Other Specifications
- CS 188-66
Specification for cast iron soil pipe and fittings.
(Issued by The U.S. Department of Commerce in 1966 includes
extra heavy and service pipe. This specification was another
version of ASTM A 74 and is occasionally referenced in some
city plumbing codes. It is no longer a current specification.)
- FM 1680
Approval standard for couplings used in hubless cast
iron systems for drain, waste, and vent, sewer, rainwater or
storm drain systems installed above and below ground in industrial,
commercial, and residential construction. (Issued by Factory
Mutual Research in January 1989. This specification is promoted
by Clamp-All Corporation for heavy duty coupling specification.
This specification is seldom referenced in any model plumbing
codes since it requires a proprietary testing agency. A better
reference is ASTM C 1277.)
- ASME/ANSI B 16.45-1998
Cast iron fittings for sovent® drainage systems.
Cast iron fittings for sovent® drainage systems. (Issued
by ASME in 1987, this specification covers cast iron sovent
aerator and deaerator fittings.)
- ASSE 1043
Cast iron fittings for sovent® drainage systems.
Cast iron fittings for sovent® drainage systems. (This specification
covers cast iron sovent aerator and deaerator fittings.)
- CSA B 602-M99
Mechanical couplings for drain, waste, and vent pipe
and sewer pipe. (This specification, issued by the Canadian
Standards Association, covers couplings used in transition between
dissimilar materials and the same materials. CSA B 602 is not
referenced as a coupling standard by any model plumbing code,
except for use as underground transition couplings. The standard
is in metric units only.)
- CSA B 70-M97
Cast iron soil pipe, fittings and means of joining.
(This specification, issued by the Canadian Standards Association,
covers cast iron soil pipe and fittings. Although the title
refers to joining, the reader is referred to CSA B 602. This
standard is in metric units only.)
- WWP 401F
Federal specification for pipe and pipe fittings, cast
iron soil. (This specification, issued by U.S. Department of
Defense, refers back to CISPI 301 and ASTM A 74 for the material
specifications. This specification includes information about
packaging, compliance reports, etc... It is probable that this
standard will be deleted by federal agencies. CISPI 301, CISPI
310, and ASTM A 74 are currently referenced by the Department
of Defense and the Army Corp of Engineers.)
- GEGS-15410
Corps of Engineers Guide Specification, Military Construction.
(This specification includes references to CISPI 301 and ASTM
A 74 for soil pipe and fittings, and CISPI 310 for hubless couplings.
This specification is also used by the General Services Administration.)
