F1 vii Foreword2 In response to a competitive request for proposals from the U.S. Environmental Protection Agency (USEPA), a Consorti
24、um 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 Association Researc
25、h 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 with oversight
26、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 a voluntary con
27、sensus 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 components - Health ef
28、fects 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 Register (53FR25586
29、). 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 established by suc
30、h 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 requirements speci
31、fied 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 products. All ref
32、erences to gallons (gal) are in U.S. gallons. This version of NSF/ANSI 60 2016 includes the following revisions: Issue 67: This issue revised language to section 8.8 regarding the allowance of the Short Term Exposure Limit (STEL) for well development/rehabilitation materials. Issue 68: This issue ra
33、ised the amount of allowable bromide in salt from 54 mg/kg to 59 mg/kg under section 7 of NSF/ANSI 60. 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 requirements for an ANS. As such, this Foreword
34、 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 69: This issue updated several pass/fail values included under the NSF/ANSI 60 (Annex C) drinking water crite
35、ria. This Standard was developed by the NSF Joint Committee 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 Mainte
36、nance schedule and can be opened for comment at any time. Comments should be sent to Chair, Joint Committee on Drinking Water Additives Treatment Chemicals at standardsnsf.org, or c/o NSF International, Standards Department, PO Box 130140, Ann Arbor, Michigan 48113-0140, USA. ix Consortium Organizat
37、ions NSF International Popularly referred to as NSF, NSF 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 pr
38、omote health and enrich the quality of life through conserving 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, e
39、quipment, procedures, and services related to health and 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 organ
40、ization in the Consortium responsible for developing this 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) fo
41、r all products covered by its Standards. Each program has 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 ap
42、plicable NSF Standard(s). Water Research Foundation The 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 developme
43、nt and maintenance of water resources to treatment technologies 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 c
44、ooperative research and development in drinking water, including 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 a
45、nd serve as the focal point for identification of research 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 membe
46、rship is comprised of drinking water program administrators 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
47、, water utilities, and the general public on issues related 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
48、, the Association is a valued contributor to the consortium and to the program. It provides the link between the additives program and the state drinking water programs. x The Conference of State Health and Environmental Managers The Conference of State Health and Environmental Managers (COSHEM), kn
49、own 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 water, wastewater, air, solid and hazardous wastes, radiological, occupational, health, and food. A standing committee on water supply focused on drinking water issues and kept the membership informed. The Conference played an important role earl
