35、 to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.3) This Standard was developed by consensus, which is defined by CSA Policy governing standardization Code of good practice for standardization as “substantial agreement. Co
36、nsensus implies much more than a simple majority, but not necessarily unanimity”. It is 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 Standard.4) To submit a request for interpretation of this S
37、tandard, please send the following information to inquiriescsagroup.org and include “Request for interpretation” in the subject line: a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;b) provide an explanation of circumstances surr
38、ounding the actual field condition; andc) where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue. Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are available on the Curr
39、ent Standards Activities page at standardsactivities.csa.ca.5) This Standard is subject to review five years from the date of publication. Suggestions for its improvement will be referred to the appropriate committee. To submit a proposal for change, please send the following information to inquirie

43、 defined in Section 9 of NSF/ ANSI 61.1.4 In this Standard, “shall” is used to express a 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; and “may” is used
44、to express an option or that which is permissible within the limits of the Standard.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 fig
45、ures are considered part of the table or figure and may be written as requirements.Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.1.5 SI units are the units of record in Canada. In this Standard, the yard/pound units are shown in parentheses.T
