2、spices 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 consensus process. The standards committees

3、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 developed on the consensus of views expre

4、ssed 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 established for this purpose by the Standards C

5、ouncil of Canada. In addition to standards it publishes as National Standards of Canada, 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 standards are developed in confor

6、mance with the policies described in the CGSB Policy and Procedures Manual for the Development 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

7、of the date of publication. Suggestions for their improvement, which are always welcome, 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

8、, including details on latest issues and amendments, and ordering instructions, is found in the CGSB Catalogue at our Web site www.tpsgc-pwgsc.gc.ca/ ongc-cgsb along with more information about CGSB products and services. Although the intended primary application of this standard is stated in its Sc

9、ope, it is important 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 d

CG

11、SB neither assumes nor 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 respon

13、Division Canadian General Standards Board Gatineau, Canada K1A 1G6 The Standards Council of Canada (SCC) is the coordinating body of the Canadian standardization network, which is composed of people and organizations involved in the development, promotion and implementation of standards. Through the

14、 collaborative efforts of Canadian standardization network members, standardization is helping to advance the social and economic well-being of Canada and to safeguard the health and safety of Canadians. The networks efforts are overseen by SCC. The principal objectives of SCC are to foster and prom

15、ote voluntary standardization as a means of advancing the national economy, supporting sustainable development, benefiting the health, safety and welfare of workers and the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international coop

16、eration in relation to standardization. An important facet of the Canadian standards development system is the use of the following principles: consensus; equal access and effective participation by concerned interests; respect for diverse interests and identification of those who should be afforded

17、 access to provide the needed balance of interests; mechanism for dispute resolution; openness and transparency; open access by interested parties to the procedures guiding the standards development process; clarity with respect to the processes; and Canadian interest consideration as the initial ba

18、sis for the development of standards. A National Standard of Canada (NSC) is a standard prepared or reviewed by an SCC-accredited SDO and approved by the SCC according to NSC approval requirements. Approval does not refer to the technical content of the standard, as this remains the responsibility o

19、f the SDO. An NSC reflects a consensus of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation of general interests, producers, regulators, users (including consumers) and others with relevant interests, as may be appropr

20、iate to the subject at hand. NSCs are intended to make a significant and timely contribution to the Canadian interest. Those who have a need to apply standards are encouraged to use NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from th

21、e SDO that publishes the standard.

SUMMARY OF METHOD 3.1 The aniline point, the 10%, 50% and 90% distillation points, the density at 15C, and the viscosity at 40C are determined, and the CGSB Cetane Index (CI) is c

49、alculated. 4. SIGNIFICANCE AND USE 4.1 The CGSB Cetane Index is useful for estimating the ASTM cetane number of diesel fuels from properties often routinely determined on the fuels. 4.1.1 This method is more suitable for estimating the cetane number of Canadian fuels, particularly those of oil sands origin. In the range below 40 cetane number, this method is preferable to that of ASTM D 976 for estimating the ASTM cetane number. Note: The CGSB Cetane Index is not a replacement for the ASTM cetane number as det
