本文件规定了确定汽油动力和电动（包括电池动力）链锯（包括导杆和锯链）反冲潜力的方法。 本文件已被证明是一种准确的测量方法，用于评估发动机容量高达80 cm3的电动链锯（包括电池供电）和汽油动力链锯的计算反冲角和与链锯反冲相关的能量。它不用于评估发动机容量超过80 cm3的链锯。此外，由于反冲机的物理尺寸限制，它不用于测试导杆切割长度超过63 cm的装置。 对本版中介绍的反冲潜力测定方法的修改旨在使结果具有更好的再现性；根据先前方法获得的测试结果仍然保持其有效性。

This document specifies the methodology for determining the kickback potential of gasoline-powered and electric-powered (including battery powered) chain-saws, complete with guide bar and saw-chain. This document has been demonstrated to be an accurate method of measurement for evaluating computed kickback angles and energy associated with chain-saw kickback for electric-powered chain-saws (including battery powered) and gasoline-powered 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, it is not intended for testing of units with guide bar cutting length in excess of 63 cm. Modifications to the methodology for determining the kickback potential introduced in this edition are aimed to have a better reproducibility of the results; test results obtained according to the previous methodology still maintain their validity.
