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. This standard does not supersede or take precedence over or displace any applicable law, regulation, or codes of any governmental authority. 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 official notice 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.

Foreword This foreword is for information only and is not a part of ANSI*/AWWA C153/A21.53. I. I.A.

Introduction. 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.

ing 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, Subcommittee 3 was directed to prepare a standard for 3-in. through 12-in. (75-mm

description of subsequent cast-iron-fittings standards is presented in the foreword of ANSI/AWWA C110/A21.10, Standard for Ductile-Iron and Gray-Iron Fittings. 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 co-secretariats were AGA, AWWA, and NEWWA, with AWWA serv-

through 300-mm) compact fittings designed to use the attendant strength of ductile iron. The 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, ANSI 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, ANSI Standard for Ductile-Iron Compact Fittings, 3 In. Through 16 In., for Water and Other Liquids, was approved 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 of this standard, designated ANSI/AWWA C153/A21.53-94, ANSI Standard for Ductile-Iron Compact Fittings, 3 In. Through 24 In. (76 mm Through 610 mm) and 54 In. Through 64 In. (1,400 mm Through 1,600 mm), for Water Service, was approved on Jan. 30, 1994, and by ANSI on Aug. 18, 1994. Major revisions included expansion of the sizes covered to include 18- through 24-in. sizes and 54- through 64-in. sizes; bends with plain-ends were added; crosses were added; coverage of reducers was expanded to four types, push-on and flange fittings were added; and the appendix on bolts, gaskets, and installation was added.

The fourth edition of this standard, designated ANSI/AWWA C153/A21.53-00, ANSI Standard for Ductile-Iron Compact Fittings for Water Service, was approved on Jan. 23, 2000, and by ANSI on June 28, 2000. Major revisions included the introduction of surge allowances, fusion-bonded epoxy coating systems, and 30- through 48-in. fittings. The fifth edition of this standard, designated ANSI/AWWA C153/A21.53-06, ANSI Standard for Ductile-Iron Compact Fittings for Water Service, was approved on Feb. 12, 2006, and by ANSI on May 19, 2006. Major revisions included the deletion of the figure and table giving details of the mechanical joint and the referencing of ANSI/ AWWA C111/A21.11 for details of mechanical-joint bell, plain end, and accessories. This sixth edition was approved on June 12, 2011. 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 direct and indirect drinking water additives. Other members of the original consortium included the American Water Works Association Research

Foundation (AwwaRF, now Water Research Foundation*) 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. 3. Two standards developed under the direction of NSF, NSF‡/ANSI 60, Drinking Water Treatment Chemicals—Health Effects, and NSF/ANSI 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 NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdiction. Accreditation of certi-

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 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.

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 Section 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

must be specified by the purchaser. The following standards contain reference dimensions useful in classifying existing cast-iron pipe: ANSI A21.6-1975 (ANSI/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 (ANSI/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. 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. AWWA 7C.1-1908 (AWWA C100-55)—Standard Specifications for Cast-Iron Pressure Fittings; Table 1. 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 xii

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

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. II.E. Advisory Information for the Purchaser and Specifier.

Purchasers and

specifiers should be aware that although products may be available that meet the intent of this standard, they may vary in dimensions, characteristics, material properties, or other features. The purchaser and specifier should become knowledgeable of the details of this standard and carefully evaluate the effect deviations from this standard may have on their project. One example of such a deviation is that some manufacturers may supply fittings with thinner flanges than indicated in the standard. While these fittings may have adequate strength for an application, a standard bolt kit may have insufficient threads on a bolt to adequately compress the gasket to prevent leakage. III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine that the products described in that standard are suitable for use in the particular application being considered.

AWWA C153/A21.53-11

Sec. 4.2

Permeation The selection of materials is critical for potable water, wastewater, and reclaimed water service and distribution piping in locations where there is likelihood the pipe will be exposed to significant concentrations of pollutants composed of low-molecular-weight petroleum products or organic solvents or their vapors. Documented research has shown that pipe materials such as polyethylene, polyvinyl chloride, and elastomers, such as those used in jointing gaskets and packing glands, are subject to permeation by low-molecular-weight organic solvents or petroleum products. If a potable water, wastewater, or reclaimed water pipe must pass through such a contaminated area or an area subject to contamination, consult with the manufacturer regarding permeation of pipe walls, jointing materials, etc., before selecting materials for use in that area.

The manufacturer may limit the amount of nonconformance by making additional acceptance tests until the nonconformance lot is bracketed, in order of manufacture, by an acceptable test at each end of the interval in question.

Sec. 5.8

Affidavit of Compliance The manufacturer shall, if requested by the purchaser, provide a sworn statement that the fittings comply with the requirements of this standard.

APPENDIX A Flanged Fittings: Bolts, Gaskets, and Installation

The bolts and gaskets to be used with flanged pipe, fittings, and appurtenances are to be selected by the purchaser for the particular pressure-service and installation requirements.

Size, length, and number of bolts are shown in Table 15 of ANSI*/AWWA C153/A21.53, Ductile-Iron Compact Fittings. Bolts conform to ASME† B18.2.1, Square and Hex Bolts and Screws—Inch Series. Nuts conform to ASME B18.2.2, Square and Hex Nuts. 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 with heavy-hex nuts. Bolts and nuts are threaded according to ASME 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, Standard Specification for Carbon Steel Bolts and Studs, 60,000 psi Tensile Strength, are suitable for use with the flanges described in ANSI/AWWA C153/A21.53 when used with the rubber gaskets described in this appendix. Higher-strength (Grade A) bolts and higher-torque valves should not be used with a gray-iron flange.

SECTION 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 shall 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 pipe and fitting sizes are specially designed gaskets, either ring or full faced, using one or more annular rings molded into the gasket to improve joint performance. By use of these or other special gaskets in combination with ductile-iron flanges, it may be possible to obtain a pressure rating greater than 350 psi (2,413 kPa) in the 24-in. (600 mm) and smaller sizes and greater than 250 psi (1,720 kPa) in the 30-in. (750 mm) and larger sizes. The manufacturer should be contacted for details.

SECTION 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: 1. The use of flanged joints underground is generally not recommended because of the rigidity of the joint. 2. Flange faces should bear uniformly on the gasket, and the bolts should be tightened in a progressively crisscross pattern, such as by first tightening the bottom bolt; 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.

3. Users of flanged joints should be careful to prevent bending or torsional strains from being applied to flanges or flanged appurtenances. Piping systems must be designed so that piping components connected by flanged joints are properly anchored, supported, or restrained to prevent breakage. 4. For best performance with flat rubber gaskets in 14-in. (350 mm) and larger sizes, ring-type gaskets are recommended rather than the full-face type. For joints utilizing the specially designed gaskets containing one or more molded annular rings, both ring-type and full-face are recommended for all sizes. 5. Impact wrenches cannot be used in many cases when assembling flanged joints because of the many variations of flange shroud diameters and impact wrench socket dimensions, in combination with nut configurations (heavy or regular hex).
