45、 Ministry of Labour in thedevelopment of this Standard.This Standard was prepared by the Technical Committee on Wire Rope, under the jurisdiction of theStrategic Steering Committee on Occupational Health and Safety.Notes:1) Use of the singular does not exclude the plural (and vice versa) when the se

46、nse allows.2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that itremains 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

47、by CSA Policy governing standardization Codeof good practice for standardization as “substantial agreement. Consensus implies much more than a simplemajority, but not necessarily unanimity”. It is consistent with this definition that a member may be included inthe Technical Committee list and yet no

48、t 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 toinquiriescsagroup.org and include “Request for interpretation” in the subject line:a) define the problem, making reference to the specific clau

49、se, and, where appropriate, include anillustrative sketch;b) provide an explanation of circumstances surrounding the actual field condition; andc) where possible, phrase the request in such a way that a specific “yes” or “no” answer will address theissue.Committee interpretations are processed in accordance with the CSA Directives and guidelines governingstandardization and are available on the Current Standards Activities page at standardsactivities.csa.ca.G4-15Steel wire rope for general purpose and for mine hoisting
