It is not a specification. AWWA standards describe minimum requirements and do not contain all of the engineering and administr
3、ative 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 pub- lication of a standard does not constitu
4、te endorsement of any product or product type, nor does AWWA test, certify, or approve any product. The use of AWWA standards is entirely voluntary. This standard does not supersede or take precedence over or displace any applicable law, regulation, or code of any governmental authority. AWWA standa
5、rds are intended to represent a consensus of the water industry that the product described will provide satisfactory ser- vice. When AWWA revises or withdraws this standard, an official notice of action will be placed on the first page of the Official Notice section of Journal American Water Works A
6、ssociation. The action becomes effective on the first day of the month following the month of Journal American Water Works Association publication of the official notice. American National Standard An American National Standard implies a consensus of those substantially concerned with its scope and
7、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,
8、 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 to
9、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 standard
10、 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 This American National Standard may be revised or withdrawn at any time.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 Natio

This edition was approved by the AWWA Board of Directors on June 19, 2016. I.C. Acceptance. In May 1985, th
22、e US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036.

23、) 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 Water Research Foundation (formerly AwwaRF) and the Conference of State Health and Environmental Managers (CO
24、SHEM). 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 r
25、equirements 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 developed under
26、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 the state o
27、r 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 organizations
28、 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 unspecified list of “u
29、nregulated 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 C302 does not address additives requirements. Users of this stan- dard
30、should consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements, including applicable standards. * Persons outside the United States should contact the appropriate authority having jurisdiction.

32、, 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 critical f
33、or 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 chlora
34、mines. 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 of the
35、ir 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 that t
36、he products described in that standard are suitable for use in the particular application being considered. III.A. Purchaser Options and Alternatives. The fo llowing information should be provided by the purchaser: 1. Standard used, that is, ANSI/AWWA C302, Standard for Reinforced Concrete Pressure
37、Pipe, Noncylinder Type, of latest revision. 2. Whether compliance with NSF/ANSI 61, Drinking Water System ComponentsHealth Effects, is required. 3. If submission of manufacturers design calculations for approval before man- ufacturing any pipe will be required. 4. Details of other federal, state or
38、provincial, and local requirements (Sec. 4.4). 5. The working pressure, surge pressure, field-test pressure, depth and weight of earth cover, trench bedding condition, and live load for which the pipe is to be designed (Sec. 4.2.1). 6. If the manufacturer is not permitted to supply pipe from invento
39、ry (Sec. 4.3.1). 7. If detailed drawings and schedules are to be submitted for review (Sec. 4.3.1 and Sec. 4.7.1). 8. If a tabulated layout schedule will be required (Sec. 4.3.2). 9. Type of cement required, if there is a preference (Sec. 4.4.1.1). Copyright 2017 American Water Works Association. All Rights Reserved.
