American National Standard An American National Standard implies a consensus of those substantially concerned with its scope
7、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, market
8、ing, purchasing, or using products, processes, or proce - dures not conforming to the standard. American National Standards are subject to periodic review, and users are cau- tioned to obtain the latest editions. Producers of goods made in conformity with an American National Standard are encouraged
9、 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. Caution n oti Ce : The American National Standards Institute (ANSI) approval date on the front cover of this stan
10、dard 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 This American National Standard may be revised or withdrawn at any time.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 reaffirm, revise, or withdraw this standard no later than five years from the date of publication. Purchasers of American N

22、 a cage or cages of steel reinforcing bars or wire; an encasing wall of concrete; and a preformed gasket of rubber to provide the joint seal between adjacent pipes. The pipe is manufactured in sizes ranging from 30 in. (760 mm) to more than 144 in. (3,660 mm) in diameter and is generally made in 16-
23、ft through 24-ft (4.8-m through 7.5-m) laying lengths. Reinforced concrete pressure pipe, steel-cylinder type, is designed for the specific combination of internal pressure and external load required for the project in accordance with the procedures outlined in AWWA Manual M9, Concrete Pressure Pipe
24、. This pipe is normally limited in working pressures to a maximum of 260 psi (1,790 kPa). This 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 Section III of the foreword). I.B. H
25、istory. In April 1943, the AWWA Board of Directors authorized the preparation of “Tentative Emergency Specifications for Concrete Pressure Pipe.” These tentative specifications, which described several types of pipe in a single document, served a useful purpose during World War II but became obsolet
26、e and were withdrawn. The first standard 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. The standard is now designated ANSI/AWWA C300. The
27、first edition of this standard was approved as tentative on Dec. 11, 1947. It was revised and approved as a standard on Jan. 13, 1952. The second edition was approved as tentative on July 19, 1957, and made a standard on Jan. 27, 1964. Subsequent editions of ANSI/AWWA C300 were approved by the AWWA
28、Board of Directors on Jan. 28, 1974; May 16, 1982; July 26, 1989; Feb. 2, 1997; June 13, 2004; and Jan. 23, 2011. This edition was approved on June 19, 2016. Installation, design, and other data pertaining to this type of pipe are described by AWWA Manual M9, Concrete Pressure Pipe. * American Natio

In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF In
30、ternational (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 Water Research Foundation (formerly AwwaRF) and the Conference of State Health and Environmental
31、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
32、 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. Specific policies of the state or local agency. 2. Two standards deve
33、loped under the direction of NSF : NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. 3. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by
34、 the state or local agency. Various certification 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 certification organizations within their jurisdictions. Accreditation of certi- fication o
35、rganizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61 does 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 unspecifie
36、d 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 C300 does not address additives requirements. Users of this
37、 stan- dard should consult the appropriate state or local agency having jurisdiction in order to * Persons outside the United States should contact the appropriate authority having jurisdiction.

Determine additives requirements, including applicable standards. 2. Determine the status of certifications by parties offering to certify products for contac
39、t with, or treatment of, drinking water. 3. Determine current information on product certification. II. Special Issues. Special issues are addressed in AWWA Manual M9, Concrete Pressure Pipe, and in Sec. II.A. II.A. Chlorine and Chloramine Degradation of Elastomers. The selection of materials is cri
40、tical for water service and distribution piping in locations where there is a possibility that elastomers will be in contact with chlorine or chloramines. Documented research has shown that elastomers such as gaskets, seals, valve seats, and encapsulations may be degraded when exposed to chlorine or
41、 chloramines. The impact of degradation is a function of the type of elastomeric material, chemical concentration, contact surface area, elastomer cross section, and environmental conditions as well as temperature. Careful selection of, and specifications for, elastomeric materials and the specifics
42、 of their application for each water system component should be considered to provide long-term usefulness and minimum degradation (swelling, loss of elasticity, or softening) of the elastomer specified. III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine
43、 that the products described in that standard are suitable for use in the particular application being considered. 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 cont
44、ain all of the engineering information needed to prepare a complete specification for a particular pipeline installation. A specific installation may require more restrictive provisions than those in the standard and most certainly will require additional design and installation features. Reference
45、to AWWA Manual M9, Concrete Pressure Pipe, should be considered a supplement to the use of this standard, and information in the manual should not be regarded as superseding any portion of this standard. The purpose of AWWA Manual M9 is to provide information concerning some of the various subjects
46、to be considered in, and the minimum standard of practice for, the design and installation of concrete pressure pipelines. The 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. Copyright 2017 American Water Works Association. All Rights Reserved.
