Forestry machinery. Portable chain-saws. Kickback test. | Status: Superseded, Withdrawn

1 Scope This International Standard specifies the methodology for determining the kickback potential of a gasoline-powered chain-saw, complete with guide bar and saw chain. This International Standard has been demonstrated to be an accurate method of measurement for evaluating computed kickback angles and energy associated with chain-saw kickback for chain-saws with engine capacity up to 80 cm3. It is not intended to evaluate chain-saws with an engine capacity of above 80 cm3. Furthermore, because of physical size limitations of the kickback machine, testing of units with guide bar cutting length in excess of 63 cm is not recommended.

NOTE — Although this International Standard is applicable to gasoline-powered chain-saws, the kickback machine and test procedure ought to be also suitable for testing of electric powered chain-saws. To aid in application of this test method to electric powered units, some instructions are included in this document that relate specifically to electric chain-saws.
