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 Gray-

Iron 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 ductile-

iron 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


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 Environ-

mental 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 theappropriate authority having jurisdiction.

x


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.

SECTION 5: VERIFICATION

Sec. 5.1 Inspection

5.1.1 Inspection and certification by manufacturer.

5.1.1.1 Quality-control and inspection practice. The manufacturer shall

establish the necessary quality-control and inspection practice to ensure compliance

with this standard. All fittings shall be clean and sound without defects that could

impair their service.

5.1.1.2 Repairs of defects. Repair of defects by welding or other methods shall

not be allowed if these repairs could adversely affect the serviceability of the fitting

or its capability to meet strength requirements of this standard.

5.1.1.3 Certification by manufacturer. If required by the purchaser, the

manufacturer shall provide a sworn statement that the inspection and all the

specified tests have been made and that the results comply with the requirements of

this standard.

5.1.1.4 Foundry records. The results of the specified tests (Sec. 5.2.1, 5.3, 5.4,

5.6, and 5.7, if applicable) shall be recorded and retained for one year and shall be

available to the purchaser at the foundry.

5.1.2 Inspection by purchaser.

5.1.2.1 Purchaser’s obligations. If the purchaser wants to inspect fittings at

the manufacturer’s plant, the purchaser shall so state in the purchaser’s specifica-

tions and describe the conditions (such as time and extent of the inspection) under

which the inspection shall be made.

5.1.2.2 Manufacturer’s obligations. The purchaser’s representative shall have

complete access to the areas of the manufacturer’s plant necessary to determine

compliance with this standard. The manufacturer shall make available for the use of



the purchaser’s representative the gauges necessary for inspection. The manufac-

turer shall assist the purchaser’s representative, as necessary, in handling the

fittings.

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


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.

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.
