3、ican 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 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
6、rvice. 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 AWWA. The action becomes effective on the first day of the month following the month of Journal AWWA publication of the official notice. Americ
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
8、es not in any respect preclude anyone, whether that person has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. Ameri- can National Standards are subject to periodic review, and users are cautioned to
9、 obtain the latest editions. 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 labels that the goods are produced in conformity with particular American National Standard
10、s. 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 This American National Standard may be revised or withdrawn at any time. ANSI procedures require that action be taken to reaffir
11、m, revise, or withdraw this standard no later than five years from the date of publication.

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
29、r Treatment ChemicalsHealth Effects, is required. 3. Quantity of sodium metabisulfite required. 4. Details of other federal, state or provincial, and local requirements (Section 4). 5. Whether the purchaser will reject product from containers or packaging with missing or damaged seals. The purchaser
30、 may reject product from bulk containers or packages with missing or damaged seals unless the purchasers tests of representative samples, conducted in accordance with Sec. 5.3, demonstrate that the product meets Copyright 2011 American Water Works Association.

31、ilure to meet the standard or the absence of, or irregularities in, seals may be sufficient cause to reject a shipment. 6. Form of shipmentbulk or package, type, and size of container (Sec. 6.2.1). 7. Whether alternative security measures have been adopted to replace or aug- ment the security measur

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.
