AWWA Standard
This document is an American Water Works Association (AWWA) standard. It is not a specification.
AWWA standards describe minimum requirements and do not contain all of the engineering and
administrative information normally contained in specifications. The AWWA standards usually
contain options that must be evaluated by the user of the standard. Until each optional feature is
specified by the user, the product or service is not fully defined. AWWA publication of a standard
does not constitute endorsement of any product or product type, nor does AWWA test, certify, or
approve any product. The use of AWWA standards is entirely voluntary. AWWA standards are
intended to represent a consensus of the water supply industry that the product described will
provide satisfactory service. When AWWA revises or withdraws this standard, an official notice of
action will be placed on the first page of the classified advertising section of Journal AWWA. The
action becomes effective on the first day of the month following the month of Journal AWWA
publication of the official notice.
American National Standard
An American National Standard implies a consensus of those substantially concerned with its scope
and provisions. An American National Standard is intended as a guide to aid the manufacturer, the
consumer, and the general public. The existence of an American National Standard does not in any
respect preclude anyone, whether that person has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the
standard. American National Standards are subject to periodic review, and users are cautioned to
obtain the latest editions. Producers of goods made in conformity with an American National
Standard are encouraged to state on their own responsibility in advertising and promotional
materials or on tags or labels that the goods are produced in conformity with particular American
National Standards.
CAUTION NOTICE: The American National Standards Institute (ANSI) approval date on the front
cover of this standard indicates completion of the ANSI approval process. This American National
Standard may be revised or withdrawn at any time. ANSI procedures require that action be taken
to reaffirm, revise, or withdraw this standard no later than five years from the date of publication.

Foreword
This foreword is for information only and is not a part of ANSI/AWWA C153/A21.53.
I. Introduction.
I.A.
Background.
The earliest record of an AWWA standard for cast-iron pipe
appears in the 1890 AWWA annual conference proceedings. In 1902, the New
England Water Works Association (NEWWA) adopted a more detailed standard
titled, “Standard Specification for Cast-Iron Pipe and Special Castings.” The next
AWWA standard for pipe and fittings, 7C.1-1908, was approved May 12, 1908, and
was followed by AWWA C100-52T, Tentative Standard Specifications for Cast Iron
Pressure Fittings, which was approved Dec. 31, 1952. A complete listing and
description of subsequent cast-iron-fittings standards is presented in the Foreword of
ANSI/AWWA C110/A21.10, American National Standard for Ductile-Iron and GrayIron Fittings, 3 In. Through 48 In. (75 mm Through 1,200 mm), For Water.
In 1926 the American Standards Association (ASA), now the American National
Standards Institute (ANSI), Committee A21 on Cast-Iron Pipe and Fittings was
organized under the sponsorship of the American Gas Association (AGA), the
American Society for Testing and Materials (ASTM), AWWA, and NEWWA. Between
1972 and 1984 the cosecretariats were AGA, AWWA, and NEWWA, with AWWA
serving as administrative secretariat. In 1984 the committee became an AWWA
committee named AWWA Standards Committee A21 on Ductile Iron Pipe and
Fittings. In 1988 NEWWA withdrew as a separate secretariat; however, it continues
to maintain its representation on the A21 committee. In 1997, AGA withdrew as
co-secretariat. The present scope of Committee A21 activity is the development of
standards and manuals addressing ductile-iron pressure pipe for water and ductileiron and gray-iron fittings for use with such pipe. These standards and manuals
include topics such as design, dimensions, materials, coatings, linings, joints,
accessories, methods of inspection and testing, and installation.
The work of Committee A21 is conducted by subcommittees. The scope of
Subcommittee 3, Fittings, includes the periodic review of all current A21 standards
for ductile-iron and gray-iron fittings; preparation of revisions and new standards
when needed; and examination of other matters pertaining to standards for fittings.
I.B. History.
At the meeting of Standards Committee A21 in 1981, Subcom-
mittee 3 was directed to prepare a standard for 3-in. through 12-in. (75-mm through
300-mm) compact fittings designed to use the attendant strength of ductile iron. The
ix
Copyright © 2000 American Water Works Association, All Rights Reserved
subcommittee was directed to present this standard to the committee for action in
1983. The first edition of this standard, designated ANSI/AWWA C153/A21.53-84,
American National Standard for Ductile-Iron Compact Fittings, 3 In. Through 12 In.
(75 mm Through 300 mm), for Water and Other Liquids, was approved by the AWWA
Board of Directors on Jan. 30, 1984, and by ANSI on Feb. 4, 1985.
The second edition of this standard, designated ANSI/AWWA C153/A21.53-88,
American National Standard for Ductile-Iron Compact Fittings, 3 In. Through 16 In.,
for Water and Other Liquids, was approved by the AWWA Board of Directors on June
19, 1988, and by ANSI on July 5, 1988. Major revisions included expansion of the
sizes covered to include 14-in. and 16-in. sizes, addition of “long” laying length
sleeves, changes in acceptance testing, and new sections on rejection of fittings and
determination of rejection. The third edition was approved by the AWWA Board of
Directors on Jan. 30, 1994, and by ANSI on Aug. 18,1994. This edition was approved
by the AWWA Board of Directors on Jan. 23, 2000.
I.C. Acceptance. In May 1985 the US Environmental Protection Agency
(USEPA) entered into a cooperative agreement with a consortium led by NSF
International (NSF) to develop voluntary third-party consensus standards and a
certification program for all direct and indirect drinking water additives. Other
members of the original consortium included the American Water Works Association
Research Foundation (AWWARF) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and
the Association of State Drinking Water Administrators (ASDWA) joined later.
In the United States, authority to regulate products for use in, or in contact
with, drinking water rests with individual states. * Local agencies may choose to
impose requirements more stringent than those required by the state. To evaluate
the health effects of products and drinking water additives from such products, state
and local agencies may use various references, including
1.
An advisory program formerly administered by USEPA, Office of Drinking
Water, discontinued on Apr. 7, 1990.
2.
Specific policies of the state or local agency.
*Persons in Canada, Mexico, and non-North American countries should contact the
appropriate authority having jurisdiction.

3.
Two standards developed under the direction of NSF, ANSI*/NSF† 60,
Drinking Water Treatment Chemicals—Health Effects, and ANSI/NSF 61, Drinking
Water System Components—Health Effects.
4.
Other references, including AWWA standards, Food Chemicals Codex, Water
Chemicals Codex,‡ and other standards considered appropriate by the state or local
agency.
Various certification organizations may be involved in certifying products in
accordance with ANSI/NSF 61. Individual states or local agencies have authority to
accept or accredit certification organizations within their jurisdiction. Accreditation
of certification organizations may vary from jurisdiction to jurisdiction.
Annex A, “Toxicology Review and Evaluation Procedures,” to ANSI/NSF 61 does
not stipulate a maximum allowable level (MAL) of a contaminant for substances not
regulated by a USEPA final maximum contaminant level (MCL). The MALs of an
unspecified list of “unregulated contaminants” are based on toxicity testing
guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use
of Annex A procedures may not always be identical, depending on the certifier.
ANSI/AWWA C153/A21.53-00 does not address additives requirements. Thus,
users of this standard should consult the appropriate state or local agency having
jurisdiction in order to
1.
Determine additives requirements including applicable standards.
2.
Determine the status of certifications by all parties offering to certify
products for contact with, or treatment of, drinking water.
3.
Determine current information on product certification.
II. Special Issues.
II.A. Special Service Application.
The fittings described in this standard are
normally used for pressurized water supply systems. Fittings used in other types of
service may require special consideration by the user of this standard (see Sec. III).
II.B. Orientation of Bolt Holes.
Although this standard does not specify the
orientation of bolt holes in the bell flanges of the mechanical joint, it is at times
convenient or necessary to have the bolt holes oriented. The normal, but not

universal, practice is to have the bolt holes straddle the vertical centerline of the
fittings, valves, and hydrants. (The vertical centerline of a fitting is determined when
the fitting is in the position to change the direction of fluid flowing in a horizontal
plane.) If orientation is necessary, this requirement should be specified.
II.C. Connecting Mechanical Joint Fittings and Aged Gray-Iron Pipe. The
following note in the 1998 edition of ANSI/AWWA C110/A21.10 cautioned about
using mechanical-joint fittings with aged existing pipe:
NOTE:
Mechanical-joint fittings should be connected carefully to aged existing
cast-iron pipe. The outside diameter of aged pipe should be measured prior to cutting
because some older pipe was manufactured to a larger diameter than is presently
specified in AWWA standards. Mechanical-joint sleeves or bell-and-spigot
(caulked-joint) sleeves are available to provide transition from existing cast-iron pipe;
however, they must be specified on the purchase order. The following standards
contain reference dimensions useful in classifying existing cast-iron pipe:
AWWA 7C.1-1908 (AWWA C100-55)—Standard Specifications for Cast-Iron
Pressure Fittings; Table 1.
ASA A21.2-1953 (AWWA C102-53)—American Standard for Cast-Iron Pit Cast
Pipe for Water or Other Liquids; Tables 2.1 and 2.2.
ANSI A21.6-1975 (AWWA C106-75)—American National Standard for Cast-Iron
Pipe Centrifugally Cast in Metal Molds for Water or Other Liquids; Tables 6.4, 6.5,
and 6.6.
ANSI A21.8-1975 (AWWA C108-75)—American National Standard for Cast-Iron
Pipe Centrifugally Cast in Sand-Lined Molds for Water or Other Liquids; Tables 8.4,
8.5, and 8.6.
II.D.
Advisory Information on Product Testing.
The standard acceptance test
for static castings is a tensile test from a coupon cast from the same iron. This is
typically done with a separately cast ASTM A536 keel block, a modified keel block, or
a Y-block. This standard provides an exception allowing the manufacturer to cut a
test coupon from the casting or its runner system as a method of qualifying fittings
when separately cast coupons are not available. The mechanical properties of iron
castings are influenced by a variety of factors including the cooling rate, iron
chemistry, casting geometry, location of gates and risers, etc. These various factors
cause an imprecise relationship between the mechanical properties in various
locations of the same casting or between the casting and the separately cast coupon.

AMERICAN NATIONAL STANDARD FOR
DUCTILE-IRON COMPACT FITTINGS
FOR WATER SERVICE
SECTION 1: GENERAL
Sec. 1.1
Scope
This standard covers 3-in. through 64-in. (76-mm through 1,600-mm)*
ductile-iron compact fittings to be used with ductile-iron pipe or pipe made of other
materials with similar outside diameters for conveying water. Minimum working
pressures by size range are as follows: 3-in. through 24-in. (76-mm through 610-mm):
350-psi (2,413-kPa); 30-in. through 48-in. (762-mm through 1,219-mm): 250-psi
(1,724-kPa); and 54-in. through 64-in. (1,400-mm through 1,600-mm): 150-psi (1,034kPa). Fittings are adequate for the rated working pressure plus a surge allowance of
100 psi or a surge allowance of half the rated working pressure, whichever is less.
Fittings with mechanical joints are listed in this standard for the 3-in. through
48-in. (76-mm through 1,219-mm) sizes. The standard also may be used for fittings of
these sizes with push-on joints or other joints as agreed on at the time of purchase.
Fittings with push-on joints and flanged joints are listed in this standard for the
54-in. through 64-in. (1,400-mm through 1,600-mm) sizes. Fittings with flange joints
are not discussed in this standard for sizes 3 in. through 48 in. (76 mm through 1,219 mm)
* Metric conversions given in this standard are direct conversions of US customary units and
are not those specified in International Organization for Standardization (ISO) standards.

Sec. 5.2
Test Procedures
5.2.1
Acceptance tests.
5.2.1.1
Physical test. The standard acceptance test for the physical character-
istics of ductile-iron fittings shall be a tensile test from coupons cast from the same
iron as the fittings. Except as otherwise provided in this standard, coupons shall be
cast and the test made in accordance with ASTM A536. The test coupon shall be
obtained, at the manufacturer’s option, from (1) the ASTM A536 keel block, modified
keel block, or Y-block separately cast coupon; (2) the casting’s runner bar system,
provided that the diameter of the runner bar at the location where the coupon is
selected is similar to the respective ASTM A536 coupon; or (3) the casting.
5.2.1.2
Acceptance values. The standard grade of iron shall be 70-50-05, with
acceptance values as follows: minimum tensile strength, 70,000 psi (483 MPa);
minimum yield strength, 50,000 psi (345 MPa); minimum elongation, 5 percent.
5.2.1.2.1 Other grades of iron. Another permissible acceptance value shall be
the 60-42-10 grade of iron, with acceptance values as follows: minimum tensile
strength, 60,000 psi (414 MPa); minimum yield strength, 42,000 psi (290 MPa);
minimum elongation, 10 percent. The manufacturer of fittings produced from this
grade must be able to provide records to demonstrate that these fittings meet the
performance test requirements of this standard.
5.2.1.3
Sampling.
At least one sample shall be taken during each period of
approximately 3 hr while the melting unit is operated continuously.
Sec. 5.3
Chemical Limitations
Analyses of the iron shall be made at sufficiently frequent intervals to ensure
compliance with the following limit: phosphorus, 0.08 percent maximum. Control of
other chemical constituents shall be maintained to meet the physical property
requirements of this standard. Samples for chemical analyses shall be representative
and shall be obtained from either an acceptance test specimen or specimens cast for
this purpose.
Sec. 5.4
Additional Tests Required by Purchaser
If tests other than those prescribed in this standard are required by the
purchaser, these tests shall be specified by the purchaser. Although it is not
Copyright © 2000 American Water Works Association, All Rights Reserved
10
AWWA C153/A21.53-00
customary to make hydrostatic proof tests of fittings at the foundry, these tests may
be made on special order at additional cost. If proof tests at the foundry are required
by the purchaser for an order of fittings, the fittings shall withstand, without leaks
or permanent distortion, hydrostatic test pressures not to exceed one and one half
times the rated working pressures.
Sec. 5.5
Performance Requirements
The manufacturer shall qualify the design of the product by performing
pressure tests on 90° bends and crosses of each size to demonstrate a minimum
safety factor of three times the rated working pressure and shall have records to
show the results of these tests. Tests of equal opening tees shall be substituted for
tests of crosses if the manufacturer produces tees but not crosses.
Sec. 5.6
Defective Specimens and Retests
When any tensile test specimen shows defective machining or lack of continuity
of metal, it shall be discarded and replaced by another specimen cast in the same
sampling period as the specimen that failed.
Sec. 5.7
Rejecting Fittings
If the test results of any sound specimen fail to meet the applicable
requirements of Sec. 5.2.1 or the chemical analyses do not conform to the limitations
of Sec. 5.3, the fittings represented by these tests or analyses shall be rejected, except
as provided in Sec. 5.7.1.
5.7.1 Determining rejection. The manufacturer may limit the amount of
rejection by making additional acceptance tests until the rejected lot is bracketed, in
order of manufacture, by an acceptable test at each end of the interval in question.

Bolt lengths shown for the 8-in. through 48-in. sizes are 1/2 in. shorter than ANSI/AWWI C111/A21.11-85 bolts for use with ANSI/AWWA C110/A21.10 fittings of these sizes.
These longer ANSI/AWWA C111/A21.11 bolts may also be provided with compact fittings of these sizes if the bolt thread length is lengthened sufficiently for this use.

NOTES:
1.
Diameter of cored holes may be tapered an additional 0.06 in.
2.
Dimension A in Table 1 is the OD of the plain end.
K1 and K2 are the dimensions across the bolt holes. The fitting bell and/or the gland may be polygon shaped.
4. The nominal thickness S of the fitting bell shall not be less than the nominal wall thickness of the fitting of which it
is a part. The S dimension shown in Table 1 is for reference and was used to calculate the fitting weights.
5. For ductile-iron glands, the flange thickness M listed above is only required surrounding the bolt holes. Ductile-iron glands
with reduced flange thickness between the bolt holes must meet the performance requirements specified in ANSI/AWWA
C111/A21.11.

APPENDIX A
Flanged Fittings—Bolts, Gaskets, and Installation
This appendix is for information only and is not part of ANSI/AWWA C153/A21.53.
The purchaser should select the bolts and gaskets to be used with flanged
fittings with consideration for the particular pressure-service and installation
requirements.
Sec. A.1
Bolts and Nuts
Size, length, and number of bolts are shown in Table 13 of ANSI*/AWWA C153/
A21.53. Bolts conform to ASME†/ANSI B18.2.1, Square and Hex Bolts and Screws
Inch Series Including Hex Cap Screws and Lag Screws, and nuts conform to ASME/
ANSI B18.2.2, Square and Hex Nuts (Inch Series). Bolts may have either square or
hex heads and either hex or heavy hex nuts. Bolts and nuts used with gray-iron
flanges should have standard square or heavy-hex bolts and heavy-hex nuts. Bolts
and nuts are threaded in accordance with ASME/ANSI B1.1, Unified Inch Screw
Threads (UN and UNR Thread Form), class 2A, external, and class 2B, internal.
Bolts and nuts of low-carbon steel conforming to the chemical and mechanical
requirements of ASTM‡ A307, Specification for Carbon Steel Bolts and Studs, 60,000
psi (414 MPa) Tensile Strength, grade B, are suitable for use with the flanges
described in ANSI/AWWA C153/A21.53 when used with the rubber gaskets covered
in this appendix. Higher-strength (Grade A) bolts and higher torque valves should
not be used when a gray-iron flange is used with a flat-ring gasket.
Sec. A.2
Gaskets
Unless otherwise specified by the purchaser, gaskets shall be made of synthetic
rubber, either ring or full face, and 1/8 in. (3.18 mm) thick. Gaskets should conform to
the dimensions shown in Table A.1. When considering the use of gaskets thinner
than 1/8 in. (3.18 mm), or gaskets of materials other than synthetic rubber, the
purchaser should contact the fitting manufacturer concerning suitability for a

particular application. Also available for most sizes are specially designed gaskets,
either ring or full faced, employing one or more annular rings molded into the gasket
to improve joint performance. By using these or other special gaskets, the
manufacturer may rate the flanged joint at a greater pressure rating than that
shown in this standard. Contact the fittings manufacturer for details.
Sec. A.3
Installation
The design, assembly, and installation of the flanged piping system are the
responsibility of the purchaser. The following suggestions are for general guidance:
a.
The use of flanged joints underground is generally not recommended
because of the rigidity of the joint.
b. Flanged faces should bear uniformly on the gasket. The bolts should be
tightened in a progressively crisscrossed pattern, such as by tightening the bottom
bolt first; then, the top bolt; next, the bolts at either side; and finally, the remaining
bolts. This process should be repeated until all bolts are adequately tightened.
c.
Ring gaskets are recommended for 14-in. (356-mm) and larger sizes if flat
gaskets are used.
d. Users of flanged fittings should be careful to prevent bending or torsional
strains from being applied to flanges. Piping systems must be designed so that piping
connected to flanges is properly anchored, supported, or restrained to prevent
breakage of fittings and flanges.
