[中文适用范围]： 本文件规定了确定带有导杆和锯链的汽油动力和电动（包括电池供电）链锯的反冲潜力的方法。 该文件已被证明是一种准确的测量方法，用于评估与电动链锯（包括电池供电）和发动机容量高达 80 的汽油动力链锯的链锯反冲相关的计算反冲角度和能量。 厘米3。 它不适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，它不适用于测试导杆切割长度超过 63 厘米的装置。 本版本中引入的确定回扣潜力的方法的修改旨在获得更好的结果再现性；根据之前的方法获得的测试结果仍然保持其有效性。 [外文原描述]： 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 cm 3 . It is not intended to evaluate chain-saws with an engine capacity of above 80 cm 3 . 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.
