36、 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 to its members and

37、 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 activities;f) To promote th

38、e 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 its members.Purpose

39、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 need.2) Use of Hydr

40、aulic 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, Standards, of the B

41、y-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, rating, testing a

42、nd 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 sent to the Technical Director of theHydraulic Institute. Th

43、e inquiry will then be directed to the appropriate technical committee for provision of a suit-able answer.If a dispute arises regarding contents of a Hydraulic Institute Standard or an answer provided by the Institute to aquestion such as indicated above, the point in question shall be sent in writ

44、ing to the Technical Director of theHydraulic Institute, 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 art. If no revi

45、sions are made for five years, thestandards are reaffirmed using the ANSI canvass procedure. Hydraulic Institute Standards, Copyright 1997-2015, All Rights ReservedviUnits of measurementMetric units of measurement are used, and corresponding US customary units appear in parentheses. Charts,graphs, a

46、nd sample calculations are also shown in both metric and US customary units. Since values given in met-ric units are not exact equivalents to values given in US customary units, it is important that the selected units ofmeasure to be applied be stated in reference to this standard. If no such statem

47、ent is provided, metric units shallgovern.Consensus for this standard was achieved by use of the canvass methodThe following organizations, recognized as having an interest in the standardization of centrifugal pumps, werecontacted prior to the approval of this revision of the standard.
