2、orHydraulic Institute, Inc.www.Pumps.org Approved August 27, 2012American National Standards Institute, Inc.Hydraulic Institute Standards, Copyright 1997-2012, All Rights ReservedApproval of an American National Standard requires verification by ANSI that therequirements for due process, consensus a
3、nd other criteria for approval have been metby the standards developer.Consensus is established when, in the judgement of the ANSI Board of StandardsReview, substantial agreement has been reached by directly and materially affectedinterests. Substantial agreement means much more than a simple majori
4、ty, but not nec-essarily unanimity. Consensus requires that all views and objections be considered,and that a concerted effort be made toward their resolution.The use of American National Standards is completely voluntary; their existence doesnot in any respect preclude anyone, whether he has approv
5、ed the standards or not,from manufacturing, marketing, purchasing, or using products, processes, or proce-dures not conforming to the standards.The American National Standards Institute does not develop standards and will in nocircumstances give an interpretation of any American National Standard.

17、ther the interests of the public in such matters as are involved in manufacturing, engineering, distribution,safety, transportation and other problems of the industry, and to this end, among other things:a) To develop and publish standards for pumps;b) To collect and disseminate information of value
18、 to its members and to the public;c) To appear for its members before governmental departments and agencies and other bodies in regard to mat-ters affecting the industry;d) To increase the amount and to improve the quality of pump service to the public;e) To support educational and research activiti
19、es;f) To promote the business interests of its members but not to engage in business of the kind ordinarily carried onfor profit or to perform particular services for its members or individual persons as distinguished from activitiesto improve the business conditions and lawful interests of all of i
20、ts members.Purpose of Standards1) Hydraulic Institute Standards are adopted in the public interest and are designed to help eliminate misun-derstandings between the manufacturer, the purchaser and/or the user and to assist the purchaser inselecting and obtaining the proper product for a particular n
21、eed.2) Use of Hydraulic Institute Standards is completely voluntary. Existence of Hydraulic Institute Standardsdoes not in any respect preclude a member from manufacturing or selling products not conforming to theStandards.Definition of a Standard of the Hydraulic InstituteQuoting from Article XV, S
22、tandards, of the By-Laws of the Institute, Section B:“An Institute Standard defines the product, material, process or procedure with reference to one or more of the fol-lowing: nomenclature, composition, construction, dimensions, tolerances, safety, operating characteristics, perfor-mance, quality,
23、rating, testing and service for which designed.”Comments from usersComments from users of this standard will be appreciated, to help the Hydraulic Institute prepare even more usefulfuture editions. Questions arising from the content of this standard may be directed to the Technical Director of theHy
24、draulic Institute. The inquiry will then be directed to the appropriate technical committee for provision of a suit-able answer.If a dispute arises regarding contents of an Institute standard or an answer provided by the Institute to a questionsuch as indicated above, the point in question shall be
25、sent in writing to the Technical Director of the Hydraulic Insti-tute, who shall initiate the appeals process.RevisionsThe Standards of the Hydraulic Institute are subject to constant review, and revisions are undertaken whenever it isfound necessary because of new developments and progress in the a
26、rt. If no revisions are made for five years, thestandards are reaffirmed using the ANSI canvass procedure.Units of measurementMetric units of measurement are used, and corresponding US customary units appear in parentheses. Charts,graphs, and example calculations are also shown in both metric and US
27、 customary units.Hydraulic Institute Standards, Copyright 1997-2012, All Rights ReservedviBecause values given in metric units are not exact equivalents to values given in US customary units, it is importantthat the selected units of measure be stated in reference to this standard. If no such statem
28、ent is provided, metricunits shall govern.Consensus for this standard was achieved by use of the Canvass MethodThe following organizations, recognized as having an interest in the standardization of controlled-volume meteringpumps, were contacted prior to the approval of this standard. Inclusion in
29、this list does not necessarily imply thatthe organization concurred with the submittal of the proposed standard to ANSI.A.W.
