I.Introduction.

I.A.Background.This standard provides direction and guidance in selecting

and purchasing fiberglass pipe for use as pressure pipe in water distribution

(including services) and transmission systems for both aboveground and below-

ground installations.

This standard describes 1-in. through 156-in. (25-mm through 4,000-mm) diameter pressure pipes. The primary materials used are thermosetting polyester or

epoxy resins, glass-fiber reinforcement, and, if used, aggregate. There are nine pressure

classes, which range from 50 psi through 450psi (345kPa through 3,103kPa), in

50-psi (345-kPa) increments. Stiffness classes described are 9, 18, 36, and 72psi (62,

124, 248, and 496kPa). This standard may be used to the extent applicable for other

sizes, pressure classes, and stiffness classes.

I.B.History.In June1971, the AWWA Engineering and Construction

T echnical and Professional Committee organized the Reinforced Plastics Committee

to evaluate both the use of reinforced plastics in the water-supply industry and the

need for appropriate AWWA standards. The Reinforced Plastics Committee found

sufficient use and interest to support a recommendation that a standard be developed

for fiberglass pipe. The Standards Council authorized the formation of the Standards

Committee on Thermosetting Fiberglass Reinforced Plastic Pipe in October1972,

and committee organization was completed in December1974. The first edition of

the standard was approved by the AWWA Board of Directors on Jan.25, 1981. The

second edition was approved on June23, 1988. The third edition was approved on --`,,```,,,,````-`-`,,`,,`,`,,`---

Jan.22, 1995. The fourth edition was approved on June17, 2001. This edition was

approved on Jan. 21, 2007.

I.C.Acceptance.In May1985, 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.

3.T wo standards developed under the direction of NSF , NSF ?/ANSI ?60,Drinking Water T reatment Chemicals—Health Effects, and NSF/ANSI 61, Drink-ing Water System Components—Health Effects.

4.Other references, including A WWA standards, Food Chemicals Codex, W ater Chemicals Codex ,§ and other standards considered appropriate by the state or local agency.V arious 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 certification organizations may vary from jurisdiction to jurisdiction.

Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61does 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 C950 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.

SECTION 3:DEFINITIONS

The following definitions shall apply in this standard:

1.Aggregate:Siliceous sand conforming to ASTM C33, except that the requirements for gradation need not apply.

2.Centrifugal casting :

A process used to manufacture tubular goods by applying resin and reinforcement to the inside of a mold that is rotated and heated,subsequently polymerizing the resin system. The outside diameter (OD) of the finished pipe is determined by the inside diameter (ID) of the mold tube. The ID of the finished pipe is determined by the amount of material introduced into the mold.Other materials that will not adversely affect the laminate performance may be

introduced in the process during manufacture of the pipe.

3.Constructor:The party that provides the work and materials for placement or installation.

4.Epoxy resin (thermosetting):

A polymer containing two or more three-membered rings, each consisting of one oxygen and two carbon atoms. The polymer is cured by cross-linking with an amine or anhydride hardener, with or without heat, catalyst, or both.

5.Fiberglass pipe: A tubular product containing glass-fiber reinforcements embedded in or surrounded by cured thermosetting resin. The composite structure may contain aggregate, granular or platelet fillers, thixotropic agents, and pigments or dyes. Thermoplastic or thermosetting liners or coatings may be included.

6.Filament winding: A process used to manufacture tubular goods by winding continuous glass-fiber roving or roving tape onto the outside of a mandrel or core pipe liner in a predetermined pattern under controlled tension. The roving may be saturated with liquid resin or preimpregnated with partially cured resin. Subsequent polymeriza-tion of the resin system may require application of heat. The ID of the finished pipe is fixed by the mandrel diameter or the inner diameter of the core pipe liner. The OD of the finished pipe is determined by the amount of material that is wound on the mandrel or core pipe liner. Other materials may be introduced in the process during the manufacture of the pipe, which will not adversely affect the laminate performance.

SECTION 4:

REQUIREMENTS

Sec. 4.1Permeation

The selection of materials is critical for water service and distribution piping in locations where there is likelihood the pipe will be exposed to significant concentrations of pollutants comprising low molecular weight petroleum products or organic solvents or their vapors. Research has documented that pipe materials, such as polyethylene, polybutylene, polyvinyl chloride, and asbestos cement, and elastomers, such as used in jointing gaskets and packing glands, are 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

--`,,```,,,,````-`-`,,`,,`,`,,`---

6C950-07

contamination, consult with the manufacturer regarding permeation of pipe walls,

jointing materials, and so forth, before selecting materials for use in that area. Sec. 4.2Workmanship

The pipe shall be free from defects, including indentations, delaminations, bubbles, pinholes, cracks, pits, blisters, foreign inclusions, and resin-starved areas

that, because of their nature, degree, or extent, detrimentally affect the strength and

serviceability of the pipe. The pipe shall be as uniform as commercially practicable in

color, opacity, density, and other physical properties.

Sec. 4.3Cell Classification System

This standard describes products defined by a cell classification system and identifies the method of manufacture (type), construction and materials (grade), and

liner construction (liner). The types, grades, and liners are identified in the following

paragraphs. It should be noted that all possible combinations of types, grades, and

liners may not be commercially available.

4.3.1Types. The product type is determined by the method of manufacture,

as follows:

Type I:Filament wound.

Type II:Centrifugally cast.

4.3.2Grades.The product grade is determined by construction (glass-fiber-

reinforced or glass-fiber-reinforced mortar) and materials (epoxy or polyester), as follows: Grade 1:Glass-fiber-reinforced epoxy (RTRP epoxy).

Grade 2:Glass-fiber-reinforced polyester (RTRP polyester).

Grade 3:Glass-fiber-reinforced epoxy mortar (RPMP epoxy).

Grade 4:Glass-fiber-reinforced polyester mortar (RPMP polyester).

4.3.3Liners. The product-liner classification is determined by whether or not

a liner is used and, if used, whether it is a thermoplastic, reinforced, or nonreinforced

thermoset. Classification of liners is as follows:

Liner A:No liner.

Liner B:Thermoplastic liner.

Liner C:Reinforced thermoset polyester liner.

Liner D:Nonreinforced thermoset polyester liner.

Liner E:Reinforced thermoset epoxy liner.

Liner F:Nonreinforced thermoset epoxy liner.

FIBERGLASS PRESSURE PIPE 7

Sec. 4.4Materials

The resins, reinforcement, colorants, fillers, and other materials, when com-bined as a composite structure, shall produce pipe products that meet the performance requirements of this standard as specified in Sec.5.1.2.

4.4.1Qualification for potable water service. Materials shall comply with the requirements of the Safe Drinking Water Act and other federal requirements.

4.4.2Certification. Fiberglass pipe intended for use in the transport of potable water shall be evaluated and certified for this use as required by the local authority.* The seal or mark of the laboratory that evaluates the pipe should be included on the fiberglass pipe.

4.4.3Gaskets and lubricants. Gaskets and lubricants shall be made from materials that (1)are compatible with the plastic materials and with each other when used together; (2)will not support the growth of bacteria; and (3)will not adversely affect the potable qualities of water.

Sec. 4.5Pipe Dimensions

4.5.1Diameters.Pipe diameters and tolerances shall be as shown in Tables 1–6 when measured in accordance with ASTM D3567. These tables include dimensions for pipe based on both inside and outside diameters. In the latter case,tables are provided for steel-pipe equivalent ODs, cast-iron (ductile-iron)-pipe equivalent ODs, and metric ODs commonly used in international practice. As a group, the tables cover nominal pipe sizes 1in. through 156in. (25mm through 4,000mm); individual tables cover only a portion of the total range.
