35、Introduction. I.A. Background. Fluidic-oscillator meters covered by this standard represent a measurement technique that differs from those used in other AWWA standards. The basis for volume measurement is a transducer element that utilizes fluidic oscillation in place of the moving mechanical eleme

36、nt required in most traditional cold-water volumetric meters. Flowing water enters the transducer and a converging entrance nozzle forms a jet flow. Two diverging walls produce opposing forces on the jet flow due to the Coand effect and cause the jet to oscillate. Each oscillation corresponds to a s

37、pecific volume of water flowing through the meter, and these are electronically detected, integrated, and displayed on the register. I.B. History. While the knowledge of fluidic principles is quite old, it was not until the 1960s that fluidic devices began to be used commercially in measurement and

38、control applications. Because of high costs, fluidic-oscillator meters were initially used in both gas and liquid industrial measurement. Within the last 10 or 15 years, advances in electronics have made reductions in size and power requirements possible and have made fluidic-oscillator meters comme

39、rcially feasible for residential water use measurement. This standard was developed by AWWA Subcommittee 380.10, which was origi- nally formed on June 10, 2000, to develop a standard for solid-state meters of capacity and application similar to ANSI/AWWA C700. On June 15, 2002, the work of the subco

40、mmittee was redirected to develop a stan- dard for fluidic-oscillator meters. The first edition of the standard was approved by the AWWA Board of Directors on Jan. 16, 2005. The second edition was approved on Jan. 17, 2010. This edition was approved on Jan. 24, 2015. I.C. Acceptance. In May 1985, th

41、e US Environmental Protection Agency (USEPA) entered 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 * American National S

42、tandards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036. The Coand effect is the observed tendency of a stream of fluid emerging from a nozzle to follow a nearby curved or flat surface. The effect was discovered in the 1930s by Henri-Marie Coand.

The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA)

44、 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 requirements more stringent than those required by the state. To evaluate the health effects of products and drinking

45、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, discontinued on Apr. 7, 1990. 2. Specific policies of the state or local agency. 3. Two standards developed under the di

46、rection of NSF: NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. 4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local

47、 agency. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdictions. Accreditation of certi- fication organizations may va

48、ry 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 “unregula

49、ted contaminants” are based on toxicity testing guidelines (noncarcinogens) 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, Louisiana, Maryland, and Vermont, at the time of this writing) 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
