24、tection Agency (USEPA), 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 Americ
25、an Water Works Association 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
26、steering committee 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 we
27、re developed using 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 w
28、ater system components - 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
29、, 1988 Federal Register (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 address
30、ed in standards established 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
31、the appropriate requirements 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 ex
32、ists for covered products. All references to gallons (gal) are in U.S. gallons. This version of NSF/ANSI 60 2016 includes the following revisions: Issue 66: This issue raised the typical use level (TUL) of carbon dioxide from 200 ppm to 600 ppm. Issue 70: Minimum criteria for the use of water in the
33、 production of drinking water treatment chemicals were addressed in this issue. Issue 71: Clarification of product security requirements under section 3.9 were added. 2 The information contained in this Foreword is not part of this American National Standard (ANS) and has not been processed in accor
34、dance with ANSIs requirements for an ANS. As such, this Foreword may contain material that has not been subjected to public review or a consensus process. In addition, it does not contain requirements necessary for conformance to the Standard. viii Issue 72: The typical usage level (TUL) for polyami
35、nes in Table 4.1 was updated from 20 mg/L to 10 mg/L. Issue 73: This revision added three analytical methods for acrylamide monomer in polyacrylamide under Annex B Issue 74: Separation process tracers were identified for evaluation under section 8. This Standard was developed by the NSF Joint Commit
36、tee on Drinking Water Additives 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

38、 International is a non-commercial 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 cons
39、erving and improving that environment. 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
40、 the environment. It is conceived 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 thi
41、s Standard. NSF conducts research; 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 ha
42、s established policies governing 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
43、mission of the Water Research 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 techn
44、ologies and water quality issues, 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, i
45、ncluding the subsequent transfer 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 resear
46、ch needs of the water supply 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 administrat
47、ors in each of the 50 states 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 rela
48、ted to state drinking water 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 consort
49、ium and to the program. It provides 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
