With respect to particular circumstances, local,state, and federal laws and regulations should be reviewed
2、.Neither API nor any of APIs employees, subcontractors, consultants, committees, or other assignees make anywarranty or representation, either express or implied, with respect to the accuracy, completeness, or usefulness of theinformation contained herein, or assume any liability or responsibility f
3、or any use, or the results of such use, of anyinformation or process disclosed in this publication. Neither API nor any of APIs employees, subcontractors,consultants, or other assignees represent that use of this publication would not infringe upon privately owned rights.API publications may be used
4、 by anyone desiring to do so. Every effort has been made by the Institute to ensure theaccuracy and reliability of the data contained in them; however, the Institute makes no representation, warranty, orguarantee in connection with this publication and hereby expressly disclaims any liability or res
5、ponsibility for loss ordamage resulting from its use or for the violation of any authorities having jurisdiction with which this publication mayconflict.API publications are published to facilitate the broad availability of proven, sound engineering and operatingpractices. These publications are not
6、 intended to obviate the need for applying sound engineering judgmentregarding when and where these publications should be utilized. The formulation and publication of API publicationsis not intended in any way to inhibit anyone from using any other practices.Classified areas may vary depending on t
7、he location, conditions, equipment, and substances involved in any givensituation. Users of this specification should consult with the appropriate authorities having jurisdiction.Users of this specification should not rely exclusively on the information contained in this document. Sound business,sci
8、entific, engineering, and safety judgment should be used in employing the information contained herein.Any manufacturer marking equipment or materials in conformance with the marking requirements of an API standardis solely responsible for complying with all the applicable requirements of that stand

11、ole well test tools intended for use in the petroleum and natural gas industry worldwide. This specification is intended to give requirements and information to both parties in the selection, manufacture, testing, and use of the tools named within the scope. Furthermore, this specification addresses
12、 the minimum requirements with which the supplier/manufacturer is to comply so as to claim conformity with this specification.Users of this specification should be aware that requirements above those outlined in this specification may be needed for individual applications. This specification is not
13、intended to inhibit a supplier/manufacturer from offering, or the user/purchaser from accepting, alternative equipment or engineering solutions. This may be particularly applicable where there is innovative or developing technology. Where an alternative is offered, the supplier/manufacturer should i
14、dentify any variations from this specification and provide details.This first edition of the specification has been authored in an effort to cover the prominent range of well test tools. Additionally included are requirements for service centers to ensure these products perform as designed when main
15、tained as defined therein. It is recognized that these requirements may merit some refinement following their utilization. Included in this specification are nine annexes (Annexes A through I), all of which are normative except Annexes H and I. Where referenced, these annexes provide mandatory requi
16、rements for conformance to this specification.Nothing contained in any API publication is to be construed as granting any right, by implication or otherwise, for the manufacture, sale, or use of any method, apparatus, or product covered by letters patent. Neither should anything contained in the pub
17、lication be construed as insuring anyone against liability for infringement of letters patent.Shall: As used in a standard, “shall” denotes a minimum requirement in order to conform to the standard.Should: As used in a standard, “should” denotes a recommendation or that which is advised but not requ
18、ired in order to conform to the standard.May: As used in a standard, “may” denotes a course of action permissible within the limits of a standard.Can: As used in a standard, “can” denotes a statement of possibility or capability.This document was produced under API standardization procedures that en
19、sure appropriate notification and participation in the developmental process and is designated as an API standard. Questions concerning the interpretation of the content of this publication or comments and questions concerning the procedures under which this publication was developed should be direc
20、ted in writing to the Director of Standards, American Petroleum Institute, 1220 L Street, NW, Washington, DC 20005. Requests for permission to reproduce or translate all or any part of the material published herein should also be addressed to the director.Generally, API standards are reviewed and re
21、vised, reaffirmed, or withdrawn at least every five years. A one-time extension of up to two years may be added to this review cycle. Status of the publication can be ascertained from the API Standards Department, telephone (202) 682-8000. A catalog of API publications and materials is published ann
22、ually by API, 1220 L Street, NW, Washington, DC 20005.Suggested revisions are invited and should be submitted to the Standards Department, API, 1220 L Street, NW, Washington, DC 20005, standardsapi.org.iiiContents1 Scope . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
