39、tee on Requirements for Electrical Safety.Interpretations: The Strategic Steering Committee on Requirements for Electrical Safety has provided the following direction for the interpretation of standards under its jurisdiction: “The literal text shall be used in judging compliance of products with th
40、e safety requirements of this Standard. When the literal text cannot be applied to the product, such as for new materials or construction, and when a relevant committee interpretation has not already been published, CSAs procedures for interpretation shall be followed to determine the intended safet
41、y principle.”Notes: 1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.2) 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 users of the Standard to judge its sui
42、tability 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. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is c
43、onsistent 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 Standard, please send the following information to inquiriescsagroup.org and include “Requ
44、est 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 surrounding the actual field condition; andc) where possible, phrase the request in such a wa
45、y 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 Current Standards Activities page at standardsactivities.csa.ca.C22.2 No. 128-16Vending machi
