16、andard does not include requirements for drivers. I.B. History. The original standard for vertical line-shaft turbine pumps presented the composite findings from studies conducted from 1949 to 1986 by committees consisting of manufacturers, consumers, and engineers. The first standard was published

17、in 1955. In 1961, the standard was revised to include standards for submersible vertical turbine pumps. Additional technical changes were added in the 1971 revision. Solid shaft motors were added in the 1977 revision, together with numerous editorial changes and conversions to the international syst

18、em of units. The 1977 standard was reaffirmed in 1982 without revision. Additional revisions were made in 1988. In 1994, AWWAs Standards Council approved development of a new standard for horizontal centrifugal pumps. The new standard was assigned to AWWA Standards Committee 276 for Horizontal Centr

19、ifugal Pumps. Upon review of pump standards development in 1996, AWWAs Standards Council modified the development pro- cess to include two new pump standards to replace ANSI/AWWA E101-88, Vertical Turbine PumpsLine Shaft and Submersible Types. As part of this action, two com- mittees were renamed. A

23、une 7, 2015. I.C. Acceptance. In May 1985, the 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 addi

24、tives. Other members of the original consortium included the Water Research Foundation* (formerly AwwaRF) 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 late

25、r. 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 water additiv

26、es 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 direction of NS

Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other sta

Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdictions. Ac

31、 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 characterization methodology (carcinogens). Use of A

Users of this stan- dard should consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements, including applicable s

33、tandards. 2. Determine the status of certifications by parties offering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on product certification. NSF/ANSI 372, Drinking Water System ComponentsLead Content, specifies restrictions for maximum lea

Currently compliance with NSF/ANSI 372 is mandatory in some states and meets the new low lead requirements of the U.S. Safe Drinking Water Act, which went into effect

35、 January 2014. II. Special Issues. II.A. General. A pumping system consists of several components: the pump, the driver, the controls, the baseplate or mounting plate, the foundation, suction and discharge piping, and in many cases auxiliary equipment such as cooling water and lubrication systems. T

36、his AWWA E 103 standard discusses only the pump unit. Users of this standard should review other publications such as the American Petroleum Institute (API) Recommended Practice 686, Recommended Practices for Machinery Installation and Installation Design; Hydraulic Institute (HI) Standard 1.3, Stan

37、dard for Centrifugal Pumps for Design and Application; and HI 2.3, Standard for Vertical Pumps for Design and Application. Users should especially review these and other publications for information on baseplates, mounting plates, foundation design, connection into suction, discharge piping systems,

38、 and component alignment recommendations. Conditions under which a pump will operate must be carefully evaluated by the purchaser and described by the purchase documents. II.A.1 Operating range. Evaluations should include the determination of the hydraulic characteristics of the pumping system and the extremes (maximum and minimum) of heads and flows under which the pump will be required to operate.
