2、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 usually contai

3、n 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 approve an

4、y 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 industry that the product describe

5、d 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 Association. The action becomes effective on the first day of the month following the mont

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,

7、 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, purchasing, or using products, processes, or proce - dures not conforming to the standar

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

9、labels that the goods are produced in conformity with particular American National Standards.

In May 1985, the US Environmental

16、 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 all direct and indirect drinking water additives. Other members of the original consortium included th

17、e 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 products for

18、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 * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036. Persons ou

19、tside the United States should contact the appropriate authority having jurisdiction.viii 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

20、under the direction of NSF International:* 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 appro

21、priate 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 certi- f

22、ication 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 of an u

23、nspecified 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 D102 does not address additives requirements. User

24、s 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 of, dr

25、inking water. 3. Determine current information on product certification. II. Special Issues. Volatile organic compound (VOC) emission and extractable regulations continue to become more restrictive and vary greatly from state to state and within states. The user of this AWWA standard should review c

26、urrent federal, state or provincial, and local regulations when selecting products in this standard. III. Use of This Standard. It is the responsibility of the user of this AWWA standard to determine that the products described in this standard are suitable for use in the particular locale and appli

A new inside coating system, ICS-6, has been added (S

32、ec. 4.4.7 and Sec. A.3.6). 4. The section on surface preparation (Sec. 4.6) has numerous major changes. 5. References to standards ISO 12944-2 and ISO 12944-5 have been added to appendix A as guidance documents on establishing exposure conditions and selecting coating systems based on exposure condi

33、tions (Sec. A.1). 6. Guidance on dissimilar metals has been added to appendix A (Sec. A.4). 7. Guidance on inaccessible areas has been expanded in appendix A (Sec. A.5). 8. Guidance on undersides of tank bottoms has been modified (Sec. A.5.4). 9. Roof construction options have changed (Sec. A.5.6 and Table A.1). V. Comments.
