3、andard This document is an American Water Works Association (AWWA) standard. It is not a specication. AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in speci- cations. The AWWA standards usually contain options

4、 that must be evaluated by the user of the standard. Until each optional feature is specied by the user, the product or service is not fully dened. 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

5、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

6、provide satisfactory service. When AWWA revises or withdraws this standard, an ofcial notice of action will be placed in the ofcial notice section of Journal AWWA. The action becomes effective on the rst day of the month following the month of Journal AWWA publication of the ofcial notice. American

7、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

8、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. Ameri- can National Standards are subject to periodic review, and users are cautioned to ob

9、tain 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.

10、CAUTION NOTICE: The American National Standards Institute (ANSI) approval date on the front cover of this standard indicates completion of the ANSI approval process. This American National Standard may be revised or withdrawn at any time. ANSI procedures require that action be taken to reafrm, revis

11、e, or withdraw this standard no later than ve years from the date of publication. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036; (212) 6

(760 mm) to more than 144 in. (3,660 mm) in diameter and is generally made in 16-ft through 24-ft (4.8-m th

18、rough 7.5-m) laying lengths. Reinforced concrete pressure pipe, steel-cylinder type, is designed for the specic combination of internal pressure and external load required for the project in accordance with the procedures outlined in AWWA Manual M9, Concrete Pressure Pipe. is pipe is normally limite

19、d in working pressures to a maximum of 260 psi (1,790 kPa). is type of pipe is used for transmission lines in irrigation, industrial, and domes- tic water supply systems, as well as for distribution feeder mains and other uses (see Sec. III of the foreword). I.B. History. In April 1943, the AWWA Boa

20、rd of Directors authorized the preparation of “Tentative Emergency Specications for Concrete Pressure Pipe.” ese tentative specications, which described several types of pipe in a single document, served a useful purpose during World War II but are now obsolete and have been withdrawn. e rst standar

21、d prepared by AWWA Water Works Practice Committee 8320D Reinforced Concrete Pipe, which was formed in 1946, described the manufacture of reinforced concrete pressure pipe, steel-cylinder type, not prestressed. e standard is now designated ANSI/AWWA C300. e rst edition of this standard was approved a

22、s tentative on Dec. 11, 1947. It was revised and approved as a standard on Jan. 13, 1952. e second edition was approved as tentative on July 19, 1957, and made a standard on Jan. 27, 1964. Subsequent editions of ANSI/AW WA C300 were approved by the AW WA Board of Directors on Jan. 28, 1974; May 16,

23、1982; July 26, 1989; Feb. 2, 1997; and June 13, 2004. is edition was approved on Jan. 23, 2011. * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036.

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

25、 and a certication 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). e A

26、merican 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 m

27、ore stringent than those required by the state. To evaluate the health eects 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, Oce of Drinking Water, discontinued on Apr.

28、7, 1990. 2. Specic policies of the state or local agency. 3. Two standards developed under the direction of NSF, NSF /ANSI 60, Drinking Water Treatment ChemicalsHealth Eects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Eects. 4. Other references, including AWWA standards, Food Chemicals

29、Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certication organizations may be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certication organ

30、izations within their jurisdiction. Accreditation of certi- cation organizations may vary from jurisdiction to jurisdiction.

ANSI/AWWA C300 does not address additives requirements. Users of this stan- dard should consult the appropriate s

Determine the status of certications by parties oering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on product certi

It is the responsibility of the user of an A WWA standard to determine that the products described in that standard are suitable for use in the particular application being co

36、nsidered. III.A. Purchaser Options and Alternatives. Purchasers are advised that, while this standard presents information on materials and procedures of manufacture of the pipe, it does not contain all of the engineering information needed to prepare a complete specication for a particular pipeline

37、 installation. A specic installation may require more restrictive provisions than those in the standards and most certainly will require additional design and installation features. Reference to AWWA Manual M9, Concrete Pressure Pipe, should be considered a supplement to the use of this standard, an

38、d information in the manual should not be regarded as superseding any portion of this standard. e purpose of AWWA Manual M9 is to provide information concerning some of the various subjects to be considered in, and the minimum standard of practice for, the design and installation of concrete pressur

39、e pipelines. e following information should be provided by the purchaser: 1. Standard usedthat is, ANSI/AWWA C300, Reinforced Concrete Pressure Pipe, Steel-Cylinder Type, of latest revision. 2. Whether compliance with NSF/ANSI 61, Drinking Water System ComponentsHealth Eects, is required. 3. Manner

40、of storage and delivery, if required of the manufacturer. 4. Working pressure, surge pressure, eld-test pressure, external loading condi- tions, and method of bedding and backlling (Sec. 4.2.2). 5.
