31、of the Hydraulic Institute are to promote the advancement of the pump manufacturing indus-try and further the interests of the public and to this end, among other things:a) Develop and publish standards.b) Address pump systems.c) Expand knowledge and resources.d) Educate the marketplace.e) Advocate
32、for the industry.Purpose of Standards and Guidelinesa) Hydraulic Institute Standards and Guidelines are adopted in the public interest and are designed to help elimi-nate misunderstandings between the manufacturer, the purchaser, and/or the user and to assist the purchaserin selecting and obtaining
33、the proper product for a particular need.b) Use of Hydraulic Institute Standards and Guidelines is completely voluntary. Existence of Hydraulic InstituteStandards does not in any respect preclude a member from manufacturing or selling products not conformingto the standards.Definition of a Standard
34、of the Hydraulic InstituteQuoting from Article XV, Standards, 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 ofthe following: nomenclature, composition, construction, dimensions, tolerances, safety,
35、operating charac-teristics, performance, quality, rating, testing and service for which designed.”Definition of a Hydraulic Institute GuidelineA Hydraulic Institute Guideline is not normative. The guideline is tutorial in nature, to help the reader better under-stand the subject matter.Comments from
36、 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 theHydraulic Institute. If appropriate, the inquiry will then be d
37、irected to the appropriate technical committee for provi-sion of a suitable answer.RevisionsAmerican National Standards of the Hydraulic Institute are subject to constant review, and revisions are under-taken whenever it is found necessary because of new developments and progress in the art. If no r
38、evisions aremade for five years, the standards are reaffirmed using the ANSI canvass procedure.DisclaimerThis document was prepared by a committee of the Hydraulic Institute and approved by following ANSI essentialrequirements. Neither the Hydraulic Institute, Hydraulic Institute committees, nor any
39、 person acting on behalf of theHydraulic Institute: 1) makes any warranty, expressed or implied, with respect to the use of any information, appa-ratus, method, or process disclosed in this document or guarantees that such may not infringe privately ownedrights; 2) assumes any liabilities with respe
40、ct to the use of, or for damages resulting from the use of, any informa-tion, apparatus, method, or process disclosed in this guideline.

41、, user, or anyone else resulting from reference to the content of this docu-ment, its application, or use.This document does not contain a complete statement of all requirements, analyses, and procedures necessary toensure safe or appropriate selection, installation, testing, inspection, and operati
42、on of any pump or associatedproducts. Each application, service, and selection is unique with process requirements that shall be determined bythe owner, operator, or its designated representative.Units of measurementMetric units of measurement are used, and corresponding US customary units appear in
43、 parentheses. Charts,graphs, and sample calculations are also shown in both metric and US customary units. Because values given inmetric units are not exact equivalents to values given in US customary units, it is important that the selected unitsof measure to be applied be stated in reference to th
44、is standard. If no such statement is provided, metric units shallgovern.ConsensusConsensus for this American National Standard was achieved by use of the canvass method. The following organi-zations, recognized as having an interest in the standardization of pumps, were contacted prior to the approv
45、al ofthis revision of the standard.

49、ormed whenthe bearing housings have reached their normal steady state operating temperatures.NOTES:This requirement does not apply to sleeve bearings used on vertically suspended pumps, because such bearings are normally inaccessible for temperature monitoring.Additionally (unless otherwise agreed) this requirement does not apply during factory testing because the time for bearing temperature stabilization may be excessive.The field-tested pump shall be operated at the specified or rated operating conditions (rate of flow, head, andspeed)
