I.Introduction. I.A.Background.The subcommittee that drafted this standard w
36、as formed in 1968. Initially, it attempted to formulate a single standard on remote-registration systems that would include both direct-reading and encoder-type systems. Because of design and application differences, it was not possible to achieve that goal. As a result, a standard pertaining to the
37、 pneumatic and electrical types of direct-reading systems was published. It was adopted in 1972 and designated as ANSI/AWWA Standard C706-72, Direct-Reading Remote Registration Systems for Cold-Water Meters. The subcommittee began to research and evaluate the various models and types of encoder-remo
38、te-registration systems for use on water meters. As with the direct-reading systems, the greatest problem encountered when composing the standard for encoder-type systems was determining the degree of adaptability required between the various systems that were being manufactured. The problem was res
39、olved by requiring that each manufacturers data-acquisition units be capable of being adaptable to, and of obtaining the necessary data from, at least two additional encoder systems manufactured according to the provisions of this standard. Present encoder systems are made that are compatible with a
40、utomatic meter reading systems that use radio, telephone, cellular, electric service lines, or some other data communication means. Compatible interface modules or circuitry may be required. I.B.History.The first edition of this standard was approved by the AWWA Board of Directors on Jan. 26, 1975.
41、The second edition was approved on Feb. 1, 1982, and reaffirmed on Jan. 26, 1992. This edition of the standard was approved by the AWWA Board of Directors on Jan. 16, 2005. I.C.Acceptance.In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consorti
42、um led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for all direct and indirect drinking water additives. Other members of the original consortium included the American Water Works Association Copyright American Water Works Association P

44、SHEM). 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 agencies may choose to impose r
45、equirements 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 1.An advisory program formerly administered by USEPA, Office of Drinking Water, disc
46、ontinued on Apr. 7, 1990. 2.Specific policies of the state or local agency. 3.Two standards developed under the direction of NSF, NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. 4.Other references, including AWWA standar
47、ds, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certification organizations may be involved in certifying products in accordance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredi
48、t certification organizations within their jurisdiction. Accreditation of certification organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and 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 (noncarcinogens) and risk chara
