19、 Standardization) Standard 6687:1994 (second edition, 1 994-1 0-01 ), developed by the IS0 Technical Committee ISO/TC 127. It supersedes the previous edition published in 1992 (adopted IS0 6687-1 982). This Standard is part of a series of Standards dealing with forestry winches used in tree harvesti
20、ng machines. The adoption of this IS0 Standard as a National Standard of Canada recognizes the acceptance of international design data and definitions for machines traded on a worldwide basis. This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Mobile Forestry Machiner
21、y under the jurisdiction of the Strategic Steering Committee on Occupational Health and Safety, and has been formally approved by the Technical Committee. A list of the members of the Technical Committee is available upon request. This Standard has been approved as a National Standard of Canada by t
