1、CAN/CGSB-3.0 No. 142.0-2014Methods of testing petroleum and associated products Cold soak filter blocking tendency of biodiesel (B100)ICS 77.060National Standard of CanadaThe CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this standard has been developed, is a government agency within
2、 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 are composed of representatives of relevant interests including produc
3、ers, 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 expressed by such representatives. CGSB has been accredited by the Standard
4、s 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 Council of Canada. In addition to standards it publishes as National St
5、andards 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 conformance with the policies described in the CGSB Policy and Procedures Ma
6、nual 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 of the date of publication. Suggestions for their improvement, which a
7、re 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, including details on latest issues and amendments, and ordering inst
8、ructions, 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 Scope, it is important to note that it remains the responsibility of the
9、 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 address all the safety aspects associated with its
10、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 nor accepts any responsibility for any injury or da
11、mage 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 any or all such patent rights. Users of this sta
12、ndard are expressly advised that determination of the validity of any such patent rights is entirely their own responsibility.

13、 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 collaborative efforts of Canadian standardization network members, st
14、andardization 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 promote voluntary standardization as a means of advancing the national eco
15、nomy, 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 cooperation in relation to standardization. An important facet of the Cana
16、dian 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 access to provide the needed balance of interests; mechanism for disp
17、ute 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 basis for the development of standards. A National Standard of Canada (N
18、SC) 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 of the SDO. An NSC reflects a consensus of a number of capable individu
19、als 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 appropriate to the subject at hand. NSCs are intended to make a significant a
20、nd 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 the SDO that publishes the standard. The responsibility for approving st
21、andards as NSCs rests with: Standards Council of Canada 270 Albert Street, Suite 200 Ottawa, Ontario K1P 6N7, CANADA How to order Publications: by telephone 819-956-0425 or 1-800-665-2472 by fax 819-956-5740 by mail CGSB Sales Centre Gatineau, Canada K1A 1G6 in person Place du Portage Phase III, 6B1

40、Web site .3 Summary of test method3.1 A sample of biodiesel is first conditioned to erase its thermal history.3.2 Then a blend of 20% by volume of this biodiesel sample and a specified isoparaffinic solvent is prepared and “cold soaked” at 1C for 16 h.3.3 The 20% blended sample is then warmed to 25C
41、 for 2-4 h.3.4 After warming, the “cold soaked” 20% blended sample is then passed at a constant rate of flow (20 mL/min) through a glass fibre filter medium (1.6 m pore size).3.4.1 The pressure drop across the filter is monitored until 300 mL of the 20% blend has passed through the filter, or 3.4.2
42、If a maximum pressure drop of 105 kPa is reached before the total volume of 20% blend is filtered, the actual volume filtered at the time of maximum pressure drop is recorded and used to calculate the CSFBT result.3.5 Results of the CSFBT test can range from 1 for a biodiesel with very good filterab
43、ility (essentially no separated materials under the test conditions), to more than 10 for a fuel with poor filterability (a relatively high level of separated materials under test conditions).4 Terms and definitionsFor the purposes of this method, the following terms and definitions apply.4.120% ble

In its neat form, biodiesel is commonly designated as B100. In the context of this test method, the biodiesel is inte

47、affinic solvent as specified in 7.1.5 InterferencesWater and inorganic sediment can interfere with the measurement of CSFBT, however biodiesel samples that meet the requirements of CAN/CGSB-3.524 generally will not have interference from water and sediment. High particulate contamination of the biod
48、iesel sample as measured by ASTM D7321 can increase the CSFBT test result. If desired, ASTM D6304 may be used to determine the dissolved water content.6 Apparatus6.1 The apparatus is shown as a diagram in Figure 1.
