1、CAN/CGSB-3.23-2016Supersedes CAN/CGSB-3.23-2011National Standard of CanadaCanadian General Standards BoardAviation turbine fuel (Grades JET A and JET A-1)The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this standard has been developed, is a government agency within Public Services

2、and Procurement Canada. CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and oth

3、er users, retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives.CGSB has been accredited by the Standards Council of Canada as

4、a national standards-development organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council of Canada. In addition to standards it publishes as National Standards of Canada, CGSB

5、 produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Policy and Procedures Manual for the Developmen

6、t and Maintenance of Standards.CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. CGSB will initiate the review of this standard within five years of the date of publication. Suggestions for their improvement, which are always welcome, shoul

7、d be brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards.An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, is found in the

8、 CGSB Catalogue at our Web site www.tpsgc-pwgsc.gc.ca/ongc-cgsb/index-eng.html along with more information about CGSB products and services.Although the intended primary application of this standard is stated in its Scope, it is important to note that it remains the responsibility of the users of th

9、e standard to judge its suitability for their particular purpose.The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone u

10、sing this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neither assumes nor accepts any responsibility for any injury or damage that may

11、 occur during or as the result of tests, wherever performed.Attention is drawn to the possibility that some of the elements of this Canadian standard may be the subject of patent rights. CGSB shall not be held responsible for identifying any or all such patent rights. Users of this standard are expr

12、essly advised that determination of the validity of any such patent rights is entirely their own responsibility.LanguageIn this Standard, “shall” states a mandatory requirement, “should” expresses a recommendation and “may” is used to express an option or that which is permissible within the limits

13、of this Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

An SCC-approved standard reflects the consensus of a number of experts whose collective interests provide, to the greatest practicable extent, a balance of representation of affected stakeholders. National Standards of Canada are intended to make a significant and timely co

17、ntribution to the Canadian interest. SCC is a Crown corporation within the portfolio of Industry Canada. With the goal of enhancing Canadas economic competitiveness and social well-being, SCC leads and facilitates the development and use of national and international standards. SCC also coordinates

18、Canadian participation in standards development, and identifies strategies to advance Canadian standardization efforts. Accreditation services are provided by SCC to various customers, including product certifiers, testing laboratories, and standards development organizations. A list of SCC programs

19、 and accredited bodies is publicly available at www.scc.ca.

Pratt however, when results are obtained by both methods, D2276 shall be considered the referee method.kThe minimum micro-separometer (M

27、SEP) rating applies from the point of manufacture to the point immediately before the fuel enters dedicated transportation to airport storage. MSEP by ASTM D7224 can be useful in determining the water separation characteristics of a batch of jet fuel even when additized with static dissipator additi

28、ve and certain other additives that do not actually degrade water separation performance in coalescing separators. When the fuel enters dedicated transportation to airport storage, or when the fuel is already in airport storage, the MSEP rating requirement shall not apply. When a fuel system icing i

29、nhibitor (see 6.5) or a corrosion inhibitor/lubricity improver (see 6.6) is added, the MSEP limits apply before its addition. For clarity MSEP results shall be reported by test method (i.e. MSEP by ASTM D3948 or MSEP by ASTM D7224). Conductivity often drops during fuel distribution due to additive d
