32、 Standards Associationxiv July 2009(3) This publication was developed by consensus, which is defined by CSA Policy governing standardization Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is

33、consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all Clauses of this publication.(4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee.(5

34、) All enquiries regarding this Standard, including requests for interpretation, should be addressed to Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6.Requests for interpretation should(a) define the problem, making reference to the specific clause,

35、 and, where appropriate, include an illustrative sketch;(b) provide an explanation of circumstances surrounding the actual field condition; and(c) be phrased where possible to permit a specific “yes” or “no” answer.Committee interpretations are processed in accordance with the CSA Directives and gui

36、delines governingstandardization and are published in CSAs periodical Info Update, which is available on the CSA Web site atwww.csa.ca.(6) Attention is drawn to the possibility that some of the elements of this Standard may be the subject of patent rights. CSA is not to be held responsible for ident

39、requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can

40、” is used to express possibility or capability. 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. Notes to tables and figures are considered part of the tab

41、le or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.1.3SI units are the units of record in Canada. In this Standard, the yard/pound units are shown in parentheses. The values stated in each measureme

42、nt system are equivalent in application; however, each system is to be used independently. Combining values from the two measurement systems can result in non-conformance with this Standard.All references to gallons are to U.S. gallons.For information on the conversion criteria used in this Standard
