25、PA), a Consortium led by NSF International (NSF) agreed to develop voluntary third-party consensus standards and a certification program for all direct and indirect drinking water additives. Other members of the Consortium include the Water Research Foundation (formerly the American Water Works Asso
26、ciation Research Foundation), the Association of State Drinking Water Administrators, the Conference of State Health and Environmental Managers, and the American Water Works Association. (COSHEM has since become inactive as an organization.) Each organization was represented on a steering committee
27、with oversight responsibility for the administration of the cooperative agreement. The Steering Committee provided guidance on overall administration and management, and the member organizations will remain active after the expiration of the cooperative agreement. The standards were developed using
28、a voluntary consensus process. All parties at interest were represented, including regulatory agencies, industry, and water suppliers; consultants; and other users of products covered by the standards. Two standards for additives products have been adopted. NSF/ANSI 61: Drinking water system compone
29、nts - Health effects currently covers indirect additives. NSF/ANSI 60, and subsequent product certification against it, will replace the USEPA Additives Advisory Program for drinking water treatment chemicals. For more information with regard to USEPAs actions, refer to the July 7, 1988 Federal Regi
30、ster (53FR25586). NSF/ANSI 60 has been developed to establish minimum requirements for the control of potential adverse human health effects from products added to water for its treatment. It does not attempt to include product performance requirements, which are currently addressed in standards est
31、ablished by such organizations as the American Water Works Association, the American Society for Testing and Materials, and the American National Standards Institute. Because this Standard complements the standards of these organizations, it is recommended that products also meet the appropriate req
32、uirements specified in the standards of such organizations. The Standard and the accompanying text are intended for voluntary use by certifying organizations, utilities, regulatory agencies, and/or manufacturers as a basis of providing assurances that adequate health protection exists for covered pr
33、oducts. All references to gallons (gal) are in U.S. gallons. This version of NSF/ANSI 60 2017 includes the following revisions: Issue 76 This issue added language permitting the use of highly substituted carboxymethyl ( 0.4) for drilling and remediation of water wells. Issue 77 Language regarding hy
34、pochlorite storage in section 6 was clarified. Issue 78 Updates were made to several pass/fail values in Annex C - Drinking Water Criteria 2 The information contained in this Foreword is not part of this American National Standard (ANS) and has not been processed in accordance with ANSIs requirement

In addition, it does not contain requirements necessary for conformance to the Standard. viii This Standard was developed by the NSF Joint Committee on Drinking Water Additi
36、ves Treatment Chemicals using the consensus process described by the American National Standards Institute. Suggestions for improvement of this Standard are welcome. This Standard is maintained on a Continuous Maintenance schedule and can be opened for comment at any time. Comments should be sent to

38、ercial agency. It is incorporated under the laws of Michigan as a not-for-profit organization devoted to research, education, and service. It seeks to solve problems involving man and his environment. It wishes to promote health and enrich the quality of life through conserving and improving that en
39、vironment. Its fundamental principle of operation is to serve as a neutral medium in which business and industry, official regulatory agencies, and the public come together to deal with problems involving products, equipment, procedures, and services related to health and the environment. It is conc
40、eived and administered as a public service organization. NSF is perhaps best known for its role in developing Standards and Criteria for equipment, products, and services that bear upon health. NSF was the lead organization in the Consortium responsible for developing this Standard. NSF conducts res
41、earch; tests and evaluates equipment, products, and services for compliance with standards and criteria; and grants and controls the use of NSF registered Marks. NSF offers product certification (Listing Services) for all products covered by its Standards. Each program has established policies gover
42、ning the associated product evaluation, Listing Services, follow-up and enforcement activities. The NSF Listing Mark is widely recognized as a sign that the product or service to which it relates complies with the applicable NSF Standard(s). Water Research Foundation The mission of the Water Researc
43、h Foundation (WRF) is to sponsor practical, applied research in behalf of the drinking water industry of North America. The scope of the research program embraces all aspects of water supply operation, from development and maintenance of water resources to treatment technologies and water quality is
44、sues, from storage and distribution system operations to health effects studies and utility planning and management activities. WRF serves as the centralized industry institution for planning, managing, and funding cooperative research and development in drinking water, including the subsequent tran
45、sfer of technology and results for practical application by the water utility community. WRFs purpose in this cooperative program is to provide a communication link with the water utilities throughout North America and serve as the focal point for identification of research needs of the water supply
46、 industry with respect to the additives program. The Association of State Drinking Water Administrators The Association of State Drinking Water Administrators (ASDWA) is a non-profit organization whose eligible membership is comprised of drinking water program administrators in each of the 50 states
47、 and seven U.S. territories. Through the organization, representatives speak with a collective voice to Congressional committees, the United States Environmental Protection Agency, professional and trade associations, water utilities, and the general public on issues related to state drinking water
48、programs. With its mission of protecting the public health through assurance of high quality drinking water, and promoting responsible, reasonable, and feasible drinking water programs at the state and federal levels, the Association is a valued contributor to the consortium and to the program. It p
49、rovides the link between the additives program and the state drinking water programs. The Conference of State Health and Environmental Managers The Conference of State Health and Environmental Managers (COSHEM), known formerly as the Conference of State Sanitary Engineers (CSSE), is currently inactive as an organization. It brought to the consortium expertise and involvement of state health and environmental program managers. The Conference was the focal point for health concerns of all state environmental programs, including drinking x water, wastewater, air, s
