Introduction.

I.A.

Background.

American National Standards Committee A21 on Cast-Iron

Pipe and Fittings

was

organized in 1926 under the sponsorship of the American Gas

Association (A.G.A.), the American Society for Testing and Materials

(ASTM),

he

American Water Works Association (AWWA), and the New England Water Works

Association (NEWWA).Between 1972 and 1984, the cosecretariats were A.G.A.,

AWWA, and NEWWA, with AWWA serving as administrative secretariat. In 1984,

the committeebecame an AWWA committee with thename AWWA Standards

Committee A21 on Ductile Iron Pipe and Fittings. In 1988, NEWWA withdrew as

a

separate secretariat; however, it continues to mainta in its represen tation n the A21

Committee. In 1997, A.G.A. withdrew as cosecretariat.

The present scope of Committee A21 activity is the prepara tion

f

standards for

cast-iron and ductile-iron pressure pipe for gas, water, and other liquids, and fittings

for usewith uch pipe. These standards include design, dimensions, mater ials,

coatings, linings, joints, accessories, and methods of inspection and testing.

The work of CommitteeA21 is conducted by subcommittees. The scope of

Subcommittee 3 , Fittings, includes the periodic review of all current A21 standards

for fittings and the preparation of revisions and new standards, when needed, for

fittings t o be used with cast-iron and ductile-iron pressure pipe included in A21

standards.

I.B. History. The evolution of AWWA and

ANSI

standards for fittings is

presented in this foreword t o provide information relating t o systems having aged

cast-iron pipe and fittings still inservice.

The earliest record of an AWWA standard for cast-iron pipe is contained in the

Report of Proceedings of the Tenth Ann ual Meeting of the American Water Works

Association

(1890). In 1902, NEWWA adopted

a

more detailed standard itled

“Standard Specification for Cast Iron Pipe and Special Castings.”

The next AWWA standard for pipe and fittings,AWWA 7C.1-1908,was approved

May 12, 1908. A second edition, AWWA C100-52T, was approved by AWWA Dec.

31,

1952, and byNEWWA Ja n. 23, 1953. The third edition, AWWA C100-54T, was

approved by AWWA Oct. 25, 1954, and finally issued

as

AWWA C100-55, having been

advanced from tentative t o standard without change June 17, 1955. AWWA C100-55

covered fittings in the size range

4

o 60 in. (102 to 1,500 mm).* The fittings were all

bell and spigot (caulked oint)

of

the so-called long-radius design. Theoutside

diameter

(OD)

for spigots varied with wall thicknesses, which were designated classes

A, B, C, and

D.

Fittings 4 to 12 in. (102 to 305 mm) were made to class D patterns,

having only one OD and pressure rating. Fittings14 to 24 in. (356 t o 610 mm) in size

were furnished in classes

B

and D, and fittings 30 to 60 in. (762 to

1,500

mm) in size

were furnished in classes A, B, C, and D. All fittings made in ccordance with AWWA

7C.1-1908 and C100-55 had the class identification cast on the fitting.

“Metric conversions given in this standard are direct conversions

of US

customary units

and are not those specified in the Interna tional Organization

for

Standardization (IS01

standards.

ASA* A21.10-1952 (AWWA C110-52) was approved byASA Sept. 30, 1952,

following approval by A W A May 4, 1951. The standard covered 3-

t o

12-in. (76-

t o

305-mm) fittings of the so-called short-body design, whichwere the subject of

extensive research and tests by Committee A21. The rated pressure givenby the

standard was 250 psi (1,724 kPa) plus waterhammer. The standard provided a safety

factor of 2.5 pluswaterhammer based on burs t ests, Hydraulic losses were

determined and compared with those found with long-radius fittings manufactured

in accordance with AWWA Standards. Theminimum grade

of

cast ron n the

standard was 25,000 psi (172.4 MPa) tensile strength.

ASA A21.10-1964 (AWWA C110-64) was approved byASA Jan. 9, 1964. The

revision covered 2-

to

48-in.

(50- to

1,219-mm) fittings. The design

of

the 14-

to

48-in.

(356- to 1,219-mm) fittings in the revision was based on an exhaustive series of burst

tests. The minimum grade of cast iron (25,000 psi [172.4 MPa] tensile strength) was

retained, and higher grades up o 35,000 psi (241.3 MPa) tensile strength were used

to secure higher pressure ratings without adically changing the thicknesses. Ductile

iron, grade 80-60-03, was also added in the 14- t o 48-in. (356- t o 1,219-mm) sizes with

a rated working pressure of 250 psi (1,724 kPa), having he same wall thicknesses as

150-psi (1,034-kPahratedgray-ironfittings. Theminimum safety factor based on

burs t tests of representative fittings

of

the weakest type was three times the rated

working pressure. Tables for flanged fittings and mechanical-joint fittings were

added for the first time.

ANSIA21.10-1971 (AWWA 2110-71) was approved byANSI July 14, 1971.

Ductile-iron fittings were added in sizes 3 to 12 in. (76 to 305 mm) and were rated

for

350 psi (2,413 kPa) working pressure, The grade

of

ductile iron waschanged t o

70-50-05

to

provide greater toughness. The safety factor against bursting was three

times the rated working pressure. If required by the purchaser on special order,

fittings were required to withstand a hydrostatic proof test not to exceed one and one

half times the rated working pressure without leaks r permanent distortions.

ANSIA21.10a-1972 (AWWA C110a-72) was approved Dec. 17, 1972, as a

supplement to ANSI A21.10-1971. The pressure rating

for

14-

to

24-in. (356-

o

610-mm)

ductile-iron fittings was increased to 350 psi (2,413 kPa).

ANSUAWWA C110-77

(ANSI

A21.10) was approved by ANSI Apr. 7, 1977. The

major change in this revision was the discontinuance

of

bell-and-spigot fittings (caulked

joints) and 2- and 21/4-in. (50- and 56-mm) fittings in the standard. These actions

were taken because the use

of

caulked joints had steadilydeclined until their use had

become a rarityand he 2- and 21/4-in. (50- and 56-mm) sizes were no longer

manufactured in the United States. (Bell-and-spigot fittings are still available from some

foundries on special order.) With the elimination of 2- and 21/4-in.

(50-

and 56-mm)

sizes, the standard ncluded

3- to

48-in. (76- o 1,219-mm)mechanical-joint and flanged

fitt ings only.

Another change made in the 1977 edition was in bolt lengths for flanged fittings

to comply with ANSIIAWWA C115lA21.15-75, Standard

for

Flanged Cast-Iron and

Ductile-Iron Pipe With Threaded Flanges. Appendix A was added to the standard to

cover bolts, gaskets, and the installationof flanged fittings. Appendix B was added as

a listing of available special fittings that arenot a part

of

the standard.These include

fittings designed t o use the a ttendant strength of ductile iron.

ANSI/AWWA CllO/A21.10-87 was approved by

ANSI

Oct. 30, 1987. The major

revisions included new sections on rejection

of

fittings and determinationof rejection,

and ductile-iron grade 60-42-10 was added. Cast marking of the country where cast

was added; Sec. 10-4.3,

Joint

Accessories, was added; and 14-in. through 48-in. (356-mm

through 1,219-mm) solid sleeves made with B-pattern equipmentwere added.

ANSI/AWWA CllO/A21.10-93 was approved byANSIAug. 10, 1993. Major

revisions in this edition of the standard included the addition of a section on health

effects and permeation, allowance

for

reduced metal-section thicknesses for ductile-

iron glands, addition

of

a precautionary note on the use of flange gaskets thinner

than Y8 in. (3.2 mm) in appendix A, addition

of

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 t o regulate products for use in,

or

in contact

with, drinking water rests with ndividual states.* Local agencies maychoose to

impose requirements more stringent than those required by the state.

To

evaluate

the health effects of products and drinking water additives rom 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 he direction of

NSF,

ANSI’/NSFS 60,

Drinking Water Treatment Chemicals-Health Effects, and ANSINSF 61, Drinking

Water System Components-Health Effects.

4. Other references, including A W A standards,

Food ChemicalsCodex,

Water Chemicals Codex,§ and other standards considered appropriate by the sta te or

local agency.

Various certification organizations may be nvolved in certifying products n

accordance with

ANSUNSF

61. Individual states

o r

local agencies have authority to

accept

or

accredit certification organizations within thei r jurisdiction. Accreditation

of certification organizations may vary from jurisdiction t o jurisdiction.

Appendix A, “Toxicology Review and Evaluation Procedures,” t o ANSUNSF 61

does not stipulate a maximum allowable level (MAL)of a contaminantfor substances

not regulated by a USEPA final maximum contaminant level (MCL). The MALSof an

unspecified list of “unregulated ontaminants” re basedn toxicity testing

guidelines (noncarcinogens) and risk characterizationmethodology (carcinogens). Use

of Appendix A procedures may not always be identical, depending on the certifier.

ANSUAWWA CllO/A21.10 does not address additives requirements. Thus, users

of this tandard should consult theappropriate tate o r local gency having

jurisdiction in order to

1. Determine additives requirements, including applicable standards.

2. Determine thestatus of certifications by allparties offering to certify

III. Use

of This Standard.

AWWA has no responsibility for the suitability or compatibility of the provisions

of this standard to any intended application by any user. Accordingly, each user

of

thisstandard s responsible for determining tha t he standard's provisions are

suitable for and compatible with that user's intended application.

1II.A. PurchaserOptions ndAlternatives. This standard includes ertain

options tha t, if desired, must be specified in the purchaser's specifications.

It

is also

necessary that such options be included on the purchase order. Also, a number of

items must be specified

to

describe completely the fittings required. The following list

summarizes the detailsandavailable options, andreferences the sections of the

standard where they are found.

1. Size, joint type, pressure rating (Sec. 1.1 and tables).

2. Joint requirements (Sec. 4.2.1 and 4.2.2).

3. Type

of

iron (Sec. 4.2.4).

4. End combinations (Sec. 4.2.5).

5 . Certification by manufacturer (Sec. 5.1.3).

6 .

Inspection by purchaser (Sec.

5.2).

7 . Elimination of cement-mortar lining (Sec. 4.3.2).Experience has indicated

that the petroleum asphaltic inside coating isnot complete protection against loss in

pipe capacity caused by tuberculation. Cement-mortar linings are recommended for

most waters.

8.

Special coatings and linings (Sec. 4.3.3).

9. Acceptance tests (Sec. 5.4).

10. Special tests (Sec. 5.6).

11. Special flange bolt-hole orientation (Sec. 4.4.3).

1II.B. Special Service Requirements. The following special service requirements

1. The fittings for which this standard is ntended are those normally used for

water. Fittings for other services may require special consideration by the purchaser.

2. The method of installat ion of fittings depends on the type of joint and

should be made in accordance with applicable parts

of ANSI/AWWA

C111/A21.11,

Rubber-Gasket Joints for Ductile-Iron and Gray-Iron Pressure Pipe and Fittings;

ANSUAWWA C600, Installation of Ductile-Iron Water Mains and Their Appurte-

nances; and recommendationsof manufacturers regarding their product.

3. Attention s directed to an apparen t conflict between this standard and

ASME/ANSI B16.1, Cast Iron Pipe Flanges and Flanged Fittings, with regard to

pressure ratings for flanged fittings.

In ANSUAWWA CllO/A21.10, flanged joint fittings are rated for 150 or 250 psi

(1,034 or 1,724 kPa) working pressure, depending on the materia l, that is,gray iron

or ductile iron; he wall thickness of gray iron; and he size

of

the fitting. The ratings

of these fittings were established on the basis

of

hydrostatic testing

of

fittings

to

bursting and providefor afactor of safety of at east 3.0 at he rated working

pressure and at ambient temperature. ANSI/AWWA CllO/A21.10 flanges that ar e

adequate for water service of

250

psi (1,724 kPa) working pressure have facing and

drilling identical to ASME/ANSI B16.1 class 125 flanges, and match class 125 B16.1

flanges, that for service at -20 to 150°F (-28.9' to 65.6 C)are rated for only 150 t o

200 psi (1,034 to 1,724 kPa), depending on the flange size and the class

or

grade of iron.

should be noted:

ASME/ANSI B16.1 covers both separate flanges and flanged fittings of gray iron

for service at both ambient and elevated temperatures. The pressure-temperature

ratings of these flanges, as set forth in ASME/ANSI B16.1 and stated on the flyleaf

of that standard, are ot based on burst strength, buthave evolved over an extended

period of time of satisfactory performance ina wide range of general service

conditions. These ratings encompass pressure combined with elevated temperature,

stresses imposed by piping, thermalstressesdue to temperaturevariations,and

many other conditions causing stress in the flange or fitting.

ASME/ANSI B16.1 also contains the design of a class 250 flange, which is much

heavier, has a larger bolt circle, and uses larger-sized bolts than the B16.1 class 125

flange and he flanges covered inANSUAWA C115/A21.15 and hisstandard.

ASME/ANSI B16.1 class 250 flanges will not connect to the B16.1 class 125 flange,

the ANSUAWWA C115/A21.15 flange, or the ANSUAWWA CllO/A21.10 flange.

4. Although this standard does not detail the orientation of bolt holes in the

flanges

of

the mechanical joint, i t is at times convenient or necessary t o have the bolt

holes specially 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 determinedwhen the fitting is n the position to change the

direction

of

fluid flowing inahorizontalplane. With standard base bends and

standard base ees, the vertical centerline is determined when the fitt ing is in a

position t o change the fluid flowing in

a

vertical plane.) If special orientation is

known t o be necessary, it should be stated on the purchase order.

REQUIREMENTS

Sec. 4.1 Permeation

The selection

of

materials is critical for water service and distribution piping n

locations where the re is likelihood the pipe will be exposed

to

significant concentra-

tions of pollutants composed of low molecular weight petroleum products or organic

solvents o r their vapors. Research has documented that pipe materialssuchas

polyethylene, polybutylene, polyvinyl chloride, and asbestos cement, and elastomers,

such as used in jointing gaskets and acking glands, may be subject to permeation by

lower molecular weight organic solvents or petroleum products. If a 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, and o

forth,

before

selecting materials

for

use in that area.

DUCTILE-IRON AND GRAY-IRON FITTINGS FOR WATER 7

For 20-in. (508-mm) and 24-in. (610-mm) fittings with a body thickness grea ter

than 1 n. (25.4 mm), a 2-in. 50.8-mm) test bar shal l be used.

5.4.2 Physical tes t -duc t i le- iron f i t t ings . The standard acceptance test

for

the

physical characteristics of ductile-iron fittings shall be a tensile test on coupons cast

from the same iron as the fittings.

Except as otherwise provided herein, coupons shall be cast and the test made in

accordance with ASTM

A536.

The test coupon shall be obtained, at the manufac-

turer’s option, from one of the following: (1) he ASTM A536 keel block, modified keel

block, or Y-block separately castcoupon; (2) the castings’ runner-bar system, rovided

that the diameter of the runner bar at the location the coupon is selected is similar

t o the respective ASTM A536 coupon; o r (3) the casting.

5.4.2.1 Acceptance value. 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.

Another permissible acceptance value shall be the 60-42-10 grade of iron, with

acceptance values as follows: minimum tensile strength, 60,000 psi (414MPa);

minimum yield strength, 42,000 psi (290 MPa); andminimum elongation, 10 percent;

provided the manufacturer of fittings produced from this grade can furnish records to

demonst rate hat such ittings meet the performance test equirements of this

standard.

5.4.3 Sampling. A t least one sampleshall be takenduringeach period of

approximately

3

h, while the melting unit is operated continuously.

Sec.

5.5

ChemicalLimitations

5.5.1

Gray-iron it t ings.

Analyses

of

the iron ngray-iron ittingsshall be

made at sufficiently frequent ntervals t o ensure compliance with the following

limits: phosphorus, 0.90 percent maximum; sulfur, 0.15 percent maximum.

Control

of

the other chemical constituentsshall be maintained

to

meet the

physical property requirements of this standard. Samples

or

chemical analyses shall

be representative and shall be obtained from either acceptance-test specimens or

specimens cast for this purpose.

5.5.2 Ductile-iron ittings. Analyses of the iron shall be made at sufficiently

frequent intervals

to

ensure compliance with he following limit: phosphorus, 0.08 ercent

maximum. Control of other chemical constituents shall be maintained t o meet the

physical property requirements of this standard.

from either an acceptance-test specimen or specimens cast for this purpose.

Samples for chemical analyses shall be representative and shall be obtained

Sec.

5.6

Additional Tests Required by the Purchaser

I f

tests other than those provided in his tandardare required by the

purchaser, such ests shall be specified by the purchaser. Although it is not customary

t o make hydrostatic proof tests of fittings a t the foundry, such tests may be made on

special order at additional cost. Ifproof tes ts at the foundry are required by the

purchaser for an order of fittings, the fittingsshallwithstand,without eaks or

permanent distortion, hydrostatic est pressures not to exceed one and one half times

the rated water working pressures.

Sec. 5.7 Defective Specimens and Retests

When any physical test specimen shows efectivemachining r lack of

continuity of metal, it shall be discarded and replaced by another specimen

cast

in

the same sampling period as the specimen tha t failed.

Sec. 5.8 Rejection of Fittings

If theestesults

of

any soundpecimen fail to meet the applicable

requirements

of

Sec. 5.4, or the chemical analyses do not conform to the limitations

of

Sec.

5.5

where applicable, the fittings represented by these tests andor analyses

shall be rejected, except as provided in Sec. 5.9.

Sec.

5.9

DeterminingRejection

The manufacturer may limit theamount

of

rejection by makingadditional

acceptance tests until the rejected lot is bracketed, in order of manufacture, by an

acceptable tes t at each end of the interval in question.
