38、l 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 the safety requirements of this Standard. When the literal text cannot be applied to the product, such as for new materials

39、 or construction, and when a relevant committee interpretation has not already been published, CSAs procedures for interpretation shall be followed to determine the intended safety principle”.January 2004Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allow

41、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 consistent with this definition that a member may be included in the Technical Committee list and yet no

44、ounding 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 guidelines governingstandardization and are published in CSAs periodical Info Update, which is available on

47、agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be developed for additional products

48、for which certification is desired by producers, consumers, or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of the Association represe

Products that comply with this Standard shall not be certified if they are found to have additional features which are in
