2、ion of ANSI/AWWA C203-08)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 A
3、WWA 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 constitute endorsement of any product or product type, nor does AWWA
4、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 standards are intended to represent a consensus of the water supply
5、 industry that the product described will provide satisfactory service. When AWWA revises or withdraws this standard, an official notice of action will be placed in the Official Notice section of Journal - American Water Works Association. The action becomes effective on the first day of the month f
6、ol- lowing 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
7、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 ap - proved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conf
8、orming 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 ma
9、terials 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 N
10、ational Standard may be revised or withdrawn at any time.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.

Card, Lockwood, Andrews June 21, 1950; May 1, 1951; and July 14, 1955. In 1951, the designations of 7A.5 and 7A.6 were changed to AWWA C203 and AWWA C20
18、4, respectively. On Mar. 27, 1957, a revision was approved that combined the two standards into one document designated as AWWA C203. Subsequent revisions were approved by the AWWA Board of Directors on Jan. 23, 1962; May 22, 1966; Jan. 29, 1973; June 25, 1978; Jan. 26, 1986; June 23, 1991; Feb. 1,

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 certificat
20、ion 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 Managers (COSHEM).

Water Research Foundation, 6666 West Quincy Avenue, Denver, CO 80235.viii 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 co
22、ntact 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,
23、 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 ChemicalsHealth Effects; and NSF/
24、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 involved in certifying products in
25、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 may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Proced
26、ures,” 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 (noncarcinogens) and risk ch
27、aracterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. ANSI/AWWA C203 does not address additives requirements. Thus, users of this standard should consult the appropriate state or local agency having jurisdiction in order to 1. De
28、termine additives requirements, including applicable standards. 2. Determine the status of certifications by all parties offering to certify prod- ucts for contact with, or treatment of, drinking water. 3. Determine current information on product certification. * Persons outside the United States sh
29、ould contact the appropriate authority having jurisdiction. NSF International, 789 North Dixboro Road, Ann Arbor, MI 48105.

30、ation. This standard defines coal- tar protective coatings and linings in terms of performance to establish the quality desired for long-term prevention of corrosion. The standard covers the external coating and internal lining of steel water pipelines for underground or underwater installation. If
31、an extended period of aboveground storage of coated pipe is anticipated, consideration should be given to the ability of the coating to resist ultraviolet degradation and other atmospheric and environmental conditions. III. Use of This Standard. It is the responsibility of the user of an AWWA standa
32、rd 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 following information should be provided by the purchaser: 1. Standard usedthat is, ANSI/AWWA C203, Coal-Tar Protective Coa
33、tings and Linings for Steel Water Pipe, of latest revision. 2. Any exceptions to the standard that may be required. 3. Operating temperature. 4. Location of coating application with reference to environmental considerations. 5. Diameter, length, and location of pipeline, including maps and drawings
34、necessary to show all details of the pipeline. 6. Application and use of materials covered in this standard should conform to warnings and instructions provided by the manufacturers and conform to existing federal and local governmental regulations. 7. For applications other than potable water, whet
35、her compliance with NSF/ ANSI 61 Drinking Water System ComponentsHealth Effects, is required (Sec. 4.2.3). 8. Requirements for outdoor storage (Sec. 1.1.1). 9. Details of other federal, state or provincial, and local requirements (Sec. 4.2). 10. If materials only are being purchased according to the
36、 requirements of Sec. 4.3 of this standard, the purchaser shall specify quantities for the following items: (1) primer by type (Sec. 4.3.2); (2) coal-tar enamel by type (Sec. 4.3.3.1 and Table 1); (3) outerwrap (Sec. 4.3.4); and (4) glass fiber inner mat (Sec. 4.3.5). The purchaser should also specify if an affidavit of compliance is required (Sec. 6.3). 11. Type of liquid adhesive (Sec. 4.3.2). 12. Type of coal-tar enamel (Sec. 4.3.3). 13. Type of outerwrap (Sec. 4.3.4). 14. Length of pipeline requiring internal protection (Sec. 4.4.1.1).
