2、00-12)ii AWWA 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 specifications. The AWWA standards usual

3、ly 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 constitute endorsement of any product or product type, nor does AWWA test, certify, or a

4、pprove 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 codes of any governmental authority. AWWA standards are intended to represent a consensus of the water supply industry that the

5、 product described 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 Official Notice section of Journal - American Water Works Association. The action becomes effective on the first day of the month f

6、ollowing 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 provisions. An American National Standard is intended as a guide to ai

7、d 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 ap - proved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not confor

8、ming to the standard. American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions. Producers of goods made in conformity with an American National Standard are encour - aged to state on their own responsibility in advertising and promotional mate

9、rials 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 indicates completion of the ANSI approval process. This American Nat

10、ional Standard may be revised or withdrawn at any time.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 ANSI approval.

This revision was approved on June 8, 2014. I.B. Acceptance. In May 1985, the

17、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 indirect drinking water additives. Other members of the original consortiu

18、m included the Water Research Foundation, (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

19、 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 states. To evaluate the health effects of products and drinking water additives from such products, state and local agenci

20、es 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 standards developed under the direction of NSF, NSF/ANSI 60, Drinking Water Treatment Chem

21、icalsHealth 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 appropriate by the state or local agency. Various certification organizations may be involv

22、ed 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- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology

23、 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 “unregulated contaminants” are based on toxicity testing guidelines

24、 * NSF International, 789 N. Dixboro Rd., 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., N. W ., Washington, DC 2000 1.ix (noncarcinogens) and risk char

25、acterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. In an alternative approach to inadvertent drinking water additives, some jurisdic- tions (including California, Maryland, Vermont, and Louisiana at the time of this writing) are

26、 calling for reduced lead limits for materials in contact with potable water. Various third-party certifiers have been assessing products against these lead content criteria, and a new ANSI-approved national standard, NSF/ANSI 372, Drinking Water System ComponentsLead Content, was published in 2010.

27、 On Jan. 4, 2011, legislation was signed revising the definition for “lead free” within the Safe Drinking Water Act (SDWA) as it pertains to “pipe, pipe fittings, plumbing fittings, and fixtures.” The changes went into effect on Jan. 4, 2014. In brief, the new provisions to the SDWA require that the

28、se products meet a weighted average lead con- tent of not more than 0.25 percent when used with respect to wetted surfaces. ANSI/AWWA C800 does not address additives requirements. Users of this stan- dard should consult the appropriate state, or local agency having jurisdiction in order to 1. Determ

29、ine additives requirements, including applicable standards. 2. Determine the status of certifications by parties offering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II. Special Issues. II.A. Lead Fittings. Referen

30、ces to lead fittings have been removed from ANSI/ AWWA C800 and the attached appendixes. The AWWA Standards Department has available to users of ANSI/A WWA C800 copies of ANSI/A WWA C800-84 information that contains references to lead fittings. III. Use of This Standard. It is the responsibility of

31、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. Products Intended for Waterworks Applications. A variety of valves, fittings, and other water conveyance devices are available on the mar

32、ket for water service. For the user, it is important to distinguish between products designated plumbing style versus waterworks service style and to ensure the proper product is selected for the specific application. Waterworks products are designed and constructed for belowground installation. This helps ensure long-term performance under a variety of installation and service conditions. The specific materials established in ANSI/AWWA C800 were selected to provide long-term performance and corrosion resistance from
