3、 Standard This document is an American Water Works Association (AWWA) standard. It is not a specification. AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifi- cations. The AWWA standards usually contain
4、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 pr
5、oduct. The 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 desc
6、ribed will provide satisfactory service. When AWWA revises or withdraws this standard, an official notice of action will be placed on the first page of the classified advertising section of Journal AWWA. The action becomes effective on the first day of the month following the month of Journal AWWA p
7、ublication 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 ex-
8、istence 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 pe
9、riodic 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 w
10、ith particular American National Standards. Caution n oti Ce : 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 This American National Standard may be revised or withdrawn at any time.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 procedure
11、s require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication.

17、f polyethylene film to sunlight, revised sections on thrust restraint and hydrostatic testing, and a discussion on making service taps on polyethylene-encased iron mains. Subsequent revisions to ANSI/AWWA C600 were approved by the AWWA Board of Directors in 1993, 1999, and 2005. This eleventh editio
18、n was approved on June 20, 2010. I.C. Acceptance. 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 and a certification program for direct and indirec
19、t drinking water additives. Other members of the original consortium included the Water Research Foundation (AwwaRF, now Water Research Foundation) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinkin
20、g 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 effe
21、cts 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. Two sta
22、ndards developed under the direction of NSF, NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. 4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appr
23、opriate by 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 jurisdiction. Accreditation of certi- f
24、ication organizations may vary from jurisdiction to jurisdiction. * NSF International, 789 N. Dixboro Road, Ann Arbor, MI 48105. Persons outside the United States should contact the appropriate authority having jurisdiction. Both publications available from National Academy of Sciences, 500 Fifth St

All Rights Reserved. xi 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
26、contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guide- lines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. ANSI/AWWA C600 do
27、es not address additives requirements. Users of this stan- dard 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 prod-
28、 ucts for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II. Special Issues. ANSI/AWWA C600, Standard for Installation of Ductile- Iron Mains and Their Appurtenances, can be used as a reference when making extensions to existing distribution
29、 or transmission systems or when constructing new distribution or transmission systems using ductile-iron mains with either mechanical or push-on joints. It is not intended for this standard to be used as a purchase document, but it may be used as a reference in purchasers documents. It is based on
30、a consensus of the committee on the minimum practice consistent with sound, economical service under normal conditions, and its applicability under any circumstances must be reviewed by a responsible engineer. The standard is not intended to preclude the manufacture, marketing, purchase, or the use
31、of any product, process, or procedure. III. 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. III.A. Purchaser Options and Alternatives. The fol
32、lowing items should be provided by the purchaser: 1. Standard usedthat is, ANSI/AWWA C600, Installation of Ductile-Iron Mains and their Appurtenances, of latest revision. 2. Whether compliance with NSF/ANSI 61, Drinking Water System ComponentsHealth Effects, is required. 3. Details of other federal,
33、 state or provincial, and local requirements (Sec. 4.2). III.B. Modification to Standard. Any modification of the provisions, definitions, or terminology in this standard must be provided by the purchaser. IV. Major Revisions.
