2、ada. 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 other users, retailers

3、, 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 a national standar

4、ds-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, CGSB produces standards to meet

5、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 Manual for the Development and Review of Standards. CGSB standards a

6、re subject to review and revision to ensure that they keep abreast of technological progress. 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

7、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 CGSB Catalogue, which is published annually and is available without charge upon request. More information is available about CGSB product

This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate author

10、ities 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 occur during or as the result of tests, wherever performed. Attention is d

11、rawn 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 expressly advised that determination of the validity of any such patent rights

12、 is entirely their own responsibility. Further information on CGSB and its services and standards may be obtained from: The Manager Standards Division Canadian General Standards Board Gatineau, Canada K1A 1G6 The Standards Council of Canada (SCC) is the coordinating body of the Canadian standardizat

13、ion 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, standardization is helping to advance the social and economic well-being of Canada and to

14、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 economy, supporting sustainable development, benefiting the health, safety and welfare of w

15、orkers 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 Canadian standards development system is the use of the following principles: consensus; equ

16、al 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 dispute resolution; openness and transparency; open access by interested parties to the proc

17、edures 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 (NSC) is a standard prepared or reviewed by an SCC-accredited SDO and approved by the SCC

18、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 individuals whose collective interests provide, to the greatest practicable extent, a balance of

19、 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 and timely contribution to the Canadian interest. Those who have a need to apply standard

20、s 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 standards as NSCs rests with: Standards Council of Canada 270 Albert Street, Suite 200 Ott

30、DIAN GENERAL STANDARDS BOARDPROPANE FOR FUEL PURPOSES1. SCOPE1.1 This standard describes two grades of propane used only for fuel purposes. These grades consist mainly of C3compounds. 1.1.1 Grade 1 is intended for use in internal combustion engines and for general industrial and commercial fuel appl

31、ications. Grade 1 maintains a minimum octane quality by limiting concentrations of low-octane components (see footnote 6).Note: The requirements for Grade 1 are derived from the GPA 2140 HD-5 specification.1.1.2 Grade 2 is adequate for most industrial and domestic uses and may also be suitable for l

32、ow severity internal combustion engine applications where a high-octane quality fuel is not required.Note: Propane was referred to as liquefied petroleum gas or LPG in prior editions of this standard. The terms LPG, LP Gas and Liquefied Petroleum Gas are used in North America to refer to various mix

33、tures of C3and C4hydrocarbon compounds. 1.2 Users of this standard are advised to take appropriate measures to address health and safety concerns related to the use and handling of propane (par. 8.2).1.3 The testing and evaluation of a product against this standard may require the use of materials a

34、nd/or equipment that could be hazardous. This standard does not purport to address 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

35、 applicable regulatory requirements prior to its use.

TERMINOLOGYThe following definitions apply in this standard:3.1 Closed-Loop Side-Stream Sampler A sample line connected to a storage tank or pipeline capable of extracting a sample and reinjecting any excess back

40、 into the product being sampled or elsewhere in the process.3.2 Propane In this standard, propane refers to a blend of the chemical propane, C3H8, plus other hydrocarbons and naturally occurring non-hydrocarbons as allowed by the specified limiting values. 3.3 Proportional Sample A sample made by co

41、mbining samples in volumetric proportion. 3.4 Recirculation Loop Piping and a transfer pump configured into a loop and used to mix the propane in a storage tank by recirculating it from one part of the tank to another. 3.5 Volume Weighted Average The arithmetic average of results for samples taken f

42、rom different batches or pipe flow for a specified time. The results are weighted to account for the volumes of the batches or total flow during the time period.4. CLASSIFICATION4.1 The propane shall be supplied in the following grades, as specified (par. 8.1.1):4.1.1 GradesGrade 1 Grade 2.5. GENERA

43、L REQUIREMENTS5.1 Grade 1 consists essentially of the chemical propane (C3H8), and Grade 2 consists predominantly of a mixture of the chemicals propane and propene (C3H6). Grades 1 and 2 shall meet the compositional requirements specified in par. 6.3 to 6.11.5.2 Non-volatile additives shall not be u

44、sed in propane. However, volatile additives1may be specified (par. 8.1.2 a).5.3 Odorization Propane distributed for fuel purposes shall be odorized2, 3, 4(par. 6.10, Appendix E, section E2, and Appendix F, section F1) to allow detection in the atmosphere at concentrations above one fifth of the lowe

45、r explosive limit of propane in air. In commercial situations, propane that will be used for chemical purposes and propane that is being moved to intermediate storage shall be odorized later if it is withdrawn for sale as a fuel.1 Corrosion inhibitors can be detrimental to some end uses of propane.2

46、 The odorization requirement of propane used for fuel purposes is a legal requirement in all Canadian jurisdictions, with each province and territory in Canada referencing CAN/CSA-B149.1 or CAN/CSA-B149.2 in gas safety, building code or related regulations.3 In commerce, two situations commonly call

47、 for unodorized propane: propane that will be used for chemical purposes (usually within a refinery, as a feedstock) and propane that is being moved to intermediate storage (often in a cavern). 4 The appropriate provincial or territorial regulator should be consulted.CAN/CGSB-3.14-2013 36. DETAILED

48、REQUIREMENTS6.1 The propane shall comply with the specified limiting values (par. 6.3 to 6.11). The specified limiting values shall not be changed. This precludes any allowances for the test method precision and adding or subtracting digits.6.1.1 For the purpose of determining conformance with the s

49、pecified limiting value, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specified limiting value, in accordance with the rounding-off method of ASTM E29.6.1.2 Where test values differ between two parties, a resolution shall be in accordance with ASTM D3244 in order to determine conformance with the specified limiting values, with the criticality of the limits set at P = 0.5.6.2 Test methods other than those referenced in this standard may be used on
