This standard is the first edition for meters used in this application. It was developed by the AWWA Standards Subcommittee on Cold-Water Me
23、ters for Residential Fire Sprinkler Applications, and it was approved by the AWWA Standards Committee on Water Meters. This first edition of the standard was approved by the AWWA Board of Directors on June 9, 2013. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered
24、into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members of the original consortium included the Water Research Foundation (formerly A
25、wwaRF), and the Conference of State Health 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 w
26、ater rests with individual states. Local agencies may choose to impose requirements more stringent than those required by the state.

Two standards developed under the direction of NSF, NSF*/ANSI 60, Drinking Water Treatment ChemicalsHealth

Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certification organizations may be involved in certi
30、fying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdiction. Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and
31、Evaluation Procedures,” to NSF/ANSI 61 does not stipulate a maximum allowable level (MAL) of a contaminant for substances 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 (noncarcino
32、gens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. In an alternative approach to inadvertent drinking water additives, some jurisdic- tions (including California, Maryland, and Vermont, at the time of this wri
33、ting) are calling for reduced lead limits for materials in contact with potable water. Various third-party certifiers have been assessing products against these lead content criteria, and a new ANSI-approved national standard, NSF/ANSI 372, Drinking Water System ComponentsLead Content, was published
34、 in 2010. On Jan. 4, 2011, legislation was signed revising the definition for lead free within the Safe Drinking Water Act (SDWA) as it pertains to “pipe, pipe fittings, plumbing fittings, and fixtures.” The changes are due to go into effect on Jan. 4, 2014. In brief, the new provisions to the SDWA
35、require that these products meet a weighted average lead content of not more than 0.25 percent. * NSF International, 789 N. Dixboro Road, Ann Arbor, MI 48105.
