It is not a specification. AWWA standards describe minimum requirements and do not contain all of the engineering and adm

3、inistrative 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 co

This standard does not supersede or take precedence over or displace any applicable law, regulation, or code of any governmental authority. AWWA

5、standards 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 W

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, mark

All Rights Reserved. x The revisions made in 1987 included new references, a caveat against prolonged exposure of polyethylene film to sunlight, revised sections on

18、thrust restraint and hydrostatic testing, and a discussion on making service taps on polyethylene-encased iron mains. Revisions made in the 1993 edition included the addition of 60-in. (1,500 mm) and 64-in. (1,600 mm) pipe, revisions to the hydrant installation section, a new section on subaqueous c

19、rossings, and a recommended procedure for tapping through polyeth- ylene encasement. For the 1999 revision, there were no major changes to the standard. Review respon- sibility was transferred to the A21 committee, but there were no changes to the alpha- numeric designation of the standard. Revision

20、s made in the 2005 edition included restrictions on filling the void between carrier and casing pipe for highway and railroad crossings, the introduction of trench- less applications, and a modification of the hydrostatic testing allowance formula. Revisions made in the 2010 edition included additio

21、nal instructions for the selec- tion and installation of polyethylene encasement, including subaqueous installations, and a reference to high-pressure water cleaning in the flushing section. This edition was approved on Jan. 14, 2017. I.C. Acceptance. In May 1985, the US Environmental Protection Age

22、ncy (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 indirect drinking water additives. Other members of the original consortium included the Water Research F

23、oundation (formerly AwwaRF) and the Conference of State Health and Environmental 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 cont

24、act 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 effects of products and drinking water additives from such products, state and local agencies may use various references, in

25、cluding 1. Specific policies of the state or local agency. * NSF International, 789 North Dixboro Road, Ann Arbor, MI 48105. Persons outside the United States should contact the appropriate authority having jurisdiction. Copyright 2017 American Water Works Association. All Rights Reserved. xi 2. Two

26、 standards developed 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

27、 appropriate 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 jurisdictions. Accreditation of ce

28、rti- fication organizations 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 o

29、f an unspecified 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 C600 does not address additives requirements

30、. 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- ucts for contact with, or treatment

31、of, drinking water. 3. Determine current information on product certification. II. Special Issues. II.A. Use as Reference. ANSI/AWWA C600, Installation of Ductile-Iron Mains and Their Appurtenances, can be used as a reference when making extensions to existing distribution or transmission systems or

32、 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 a consensus of the committe

33、e 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 use of any product, process, or procedure. * Both publications available from National Academy of Sciences, 500 Fifth Street, NW, Washington, DC 20001.
