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 options that must be evaluated by

4、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 product. The use of AWWA standards i

5、s 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 described will provide satisfactory se

7、an 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 existence of an American National Standard do

Ameri- can National Standards are subject to periodic review, and users are cautioned to

In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop v

17、oluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members of the original consortium included the American Water Works Association Research Foundation (AwwaRF, now Water Research Foundation*) and the Conference of State Healt

18、h 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 contact with, drinking water rests with individual states. Local

19、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, including two standards developed under the direction of NSF, N

20、SF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 60. Individual states or local agencies have authority to accept or

21、accredit certification organizations within their jurisdiction. Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. * Water Research Foundation, 6666 W.

All Rights Reserved. ix Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 60 does not stipulate a maximum allowable level (MAL) of a contaminant for sub

23、stances 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 characterization methodology (carcinogens). Use of Annex A procedures may not always be identical,

24、depending on the certifier. ANSI/AWWA B601 addresses additives requirements in Sec. 4.3 of the standard. The transfer of contaminants from chemicals to processed water or to residual solids is becoming a problem of greater concern. The language in Sec. 4.3.2 is a recommenda- tion only for direct add

25、itives used in the treatment of potable water to be certified by an accredited certification organization in accordance with NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects. However, users of the standard may opt to make this certification a requirement for the product. Users of this s

26、tandard should also 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, drinking w

27、ater. 3. Determine current information on product certification. II. Special Issues. This standard has no applicable information for this section. 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 suitabl

28、e 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 B601, Sodium Metabisulfite, of latest revision. 2. Whether compliance with NSF/ANSI 60, Drinking Wate

Sec. 1.2 Purpose The purpose of this standard

36、is to provide the minimum requirements for sodium metabisulfite, including physical, chemical, sampling, packaging, ship- ping, and testing requirements. Sec. 1.3 Application This standard can be referenced in documents for purchasing and receiv - ing sodium metabisulfite and can be used as a guide

37、for testing the physical and chemical properties of sodium metabisulfite samples. The stipulations of this standard apply when this document has been referenced and then only to sodium metabisulfite used in the treatment of potable water, wastewater, or reclaimed water.
