2、 STANDARDS BOARD (CGSB), under whose auspices this standard has been developed is a government agency within Public Works and Government Services 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 consen
3、sus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is dev
4、eloped on the consensus of views expressed by such representatives. CGSB has been accredited by the Standards Council of Canada as a national standards-development organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures establish
5、ed for this purpose by the Standards Council of Canada. In addition to standards it publishes as national standards, CGSB 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 stand
6、ards are developed in conformance with the policies described in the CGSB Policy Manual for the Development and Review of Standards. CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. Suggestions for their improvement, which are always welco
7、me, should 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 fo
8、und in the CGSB Catalogue, which is published annually and is available without charge upon request. More information is available about CGSB products and services at our Web site www.ongc-cgsb.gc.ca. Although the intended primary application of this standard is stated in its Scope, it is important
9、to note that it remains the responsibility of the users of the 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 ad
10、dress all the safety aspects associated with its use. Anyone using 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 no
11、r accepts any responsibility for any injury or damage that may 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

27、hydrogen in the presence of a catalyst.12The synthetic hydrocarbon content, aromatics, distillation slope, and lubricity criteria only apply to aviation turbine fuels produced to this specification that contain syntheteic hydrocarbons. The criteria do not apply to aviation turbine fuels produced to

The supplier shall record the amount and names of each additive.6.1.1 The amount of each additive used in the fuel shall be determined by the test method (par. 5.13 and par. 8.6) or by volume reconciliation. Proce
35、dures for volume reconciliation should include recording the volume of additive introduced to the fuel and the volume of fuel additized in appropriate units.6.2 Static Dissipator Additive (SDA) Static dissipator additive Stadis 450116shall be added to the fuel to meet the electrical conductivity req
36、uirements specified in par. 5.12.1. The original concentration of the SDA shall not exceed 3 mg/L.6.2.1 When additive depletion is evident by a conductivity loss, further addition of the SDA is permitted as follows: If the original concentration of the SDA is not known, then an original addition of
37、3 mg/L is assumed and further addition of SDA shall not exceed 2 mg/L. The cumulative concentration of the SDA shall not exceed 5 mg/L.6.2.2 Electrical conductivity varies with temperature.
