This edition approved Jan. 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. 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. This American National Standard may be revised or withdrawn at any time.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.

Science and Technology AWWA unites the entire water community by developing and distributing authoritative scientific and technological knowledge.

Through its members, AWWA develops industry standards for products and processes that advance public health and safety.

A Introduction A Use of This Standard B Manufacturer Options and Alternatives A Minimum Axial Strength Requirements B Minimum Axial Strength Requirements B Beam Strength Requirements 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 belowground installations.

This standard describes 1-in. 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 psi kPa through 3, kPa , in psi kPa increments. Stiffness classes described are 9, 18, 36, and 72 psi 62, , , and kPa. This standard may be used to the extent applicable for other sizes, pressure classes, and stiffness classes.

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 October , and committee organization was completed in December The second edition was approved on June 23, The third edition was approved on Jan.

The fourth edition was approved on June 17, This edition was approved on Jan. To evaluate the health effects of products and drinking water additives from such products, state and local agencies may use various references, including 1. Specific policies of the state or local agency. 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. Use of Annex A procedures may not always be identical, depending on the certifier. 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.

Determine the status of certifications by all parties offering to certify products for contact with, or treatment of, drinking water. Determine current information on product certification. Special Issues.

Nominal metric pipe sizes, dimensions, and tolerances were obtained from ISO and CEN product standards for fiberglass pipes. 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.

Purchaser Options and Alternatives. The following items should be covered by the purchaser: 1. Specific service and installation considerations. Lineal feet of each pressure and stiffness class and size. Pipe diameter size and series Sec. Pressure classes Sec. Stiffness classes Sec. Whether plant inspection is required Sec. The purchaser may also specify the following: 1. Cell classification Sec. Standard laying lengths Sec. Joint configuration Sec. Line layout showing pressure zones, including applicable design and transient pressures within zones and points of change between zones.

Manufacturer Options and Alternatives. The following items should be provided by the manufacturer: 1. Stiffness class Sec. Joint details Sec. Nominal wall thickness. Total quantity of jointing materials and field allowances. When requested by the purchaser, it is understood that the manufacturer also will supply the following: 1. Special design calculations. Special lengths Sec. Special preparations needed for shipment Sec.

Affidavit of compliance Sec. Major Revisions. Major revisions made to the standard in this edition include the following: 1. Diameter range increased to in. Pressure classes , , , psi 2,, 2,, 2,, 3, kPa added. Table 5 metric OD updated. Several tables updated to reflect additional diameter and pressure classes. Modification to Standard. Service and distribution piping systems and transmission piping systems are included.
