AWWA standards describe minimum requirements and do not contain all of the engineering and administrative informa
3、tion normally contained in specifications. The AWWA standards usually contain options that must be evaluated by the user of the standard. Until each optional feature is specified by the user, the product or service is not fully defined. AWWA pub- lication of a standard does not constitute endorsemen
4、t of any product or product type, nor does AWWA test, certify, or approve any product. The use of AWWA standards is entirely voluntary. This standard does not supersede or take precedence over or displace any applicable law, regulation, or code of any governmental authority. AWWA standards are inten
5、ded to represent a consensus of the water supply industry that the product described will provide satisfactory service. When AWWA revises or withdraws this standard, an official notice of action will be placed on the first page of the Official Notice section of Journal American Water Works Associati
6、on. The action becomes effective on the first day of the month following the month of Journal American Water Works Association publication of the official notice. American National Standard An American National Standard implies a consensus of those substantially concerned with its scope and provisio
7、ns. An American National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether that person has ap - proved the standard or not, from manufacturing, marketing, purc
8、hasing, or using products, processes, or procedures not conforming to the standard. American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions. Producers of goods made in conformity with an American National Standard are encour - aged to state o
9、n their own responsibility in advertising and promotional materials or on tags or labels that the goods are produced in conformity with particular American National Standards. Caution n oti Ce : The American National Standards Institute (ANSI) approval date on the front cover of this standard indica
10、tes completion of the ANSI approval process. This American National Standard may be revised or withdrawn at any time. ANSI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication. Purchasers of American National Sta

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
20、WWA Standards Committee 276 for Horizontal Centrifugal Pumps was changed to AWWA Standards Committee 276 for Horizontal and Vertical Line-Shaft Pumps. Committee 276 was charged with development of ANSI/AWWA E103, Horizontal and Vertical Line-Shaft Pumps. AWWA Standards Committee 375 for Vertical Tur
21、bine Pumps was changed to AWWA Standards Committee 375 for Submersible Vertical Turbine Pumps.

22、ed. viii of ANSI/AWWA E102, Submersible Vertical Turbine Pumps. During development of these two replacement standards, ANSI/AWWA E101-88 was withdrawn effective June 2000. The first edition of ANSI/AWWA E103 was approved by the AWWA Board of Directors on June 24, 2007. This edition was approved on J
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
27、F : NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects, and NSF/ANSI 372 Drinking Water System ComponentsLead Content. 4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other sta
28、ndards considered appropriate by the state or local 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. Ac
29、creditation of certi- fication organizations may vary from jurisdiction to jurisdiction. * Water Research Foundation, 6666 West Quincy Avenue, Denver, CO 80235.

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
32、nnex A procedures may not always be identical, depending on the certifier. ANSI/AWWA E103 does not address additives requirements. 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
34、d content of materials in contact with drinking water. The user shall specify NSF/ANSI 372 when applicable in the purchase documents. 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.
