17.2 Replacement:The machine is ope

17.2更换：<br><br>机器空载运行。机器配备了符合8.14.2 a）103）的最不利的切割方法。<br><br>串联电动机的供电电压应使切割装置的旋转速度与12.2.1在额定电压或额定电压范围的下限处获得的旋转速度相同。使用非金属细丝或一个或多个可枢转安装的切割元件作为切割装置的其他电动机类型和割草机均在额定电压或额定电压范围的下限下运行。<br><br>机器运行48小时。如果对第12条中的测试使用相同的样品进行测试，则第48条中的测试时间将减少48小时。在测试期间，按照8.14的规定将机器置于其正常工作位置.2。

17.2 更换：<br><br>机器在无负载下运行。根据 8.14.2 a） 103，机器配备最不利的切割装置。<br><br>系列电机的电压为，切割手段的旋转速度与额定电压或额定电压范围下限时在 12.2.1 中获得的转速相同。其他电机类型和割草机采用非金属丝或一个或多个关键安装的切割元件，因为切割装置在额定电压或额定电压范围的下限下运行。<br><br>机器运行 48 小时。如果测试是在用于第12条测试的同一样本上进行的，则48小时会因第12条测试所需的运行时间而减少。在测试期间，机器根据 8.14.2 处于正常工作位置。

17.2 Replacement:The machine is operated at no load. The machine is fitted with the most unfavourable cutting means in accordance with 8.14.2 a) 103).Series motors are supplied at a voltage such that the rotating speed of the cutting means is the same as that obtained in 12.2.1 at rated voltage or the lower limit of the rated voltage range. Other motor types and lawnmowers employing non-metallic filaments or one or more pivotally mounted cutting elements as the cutting means are operated at rated voltage or the lower limit of the rated voltage range.The machine is operated for 48 h. If the test is conducted on the same sample used for the tests of Clause 12, the 48 h is reduced by the running time necessary for the tests of Clause 12. During the test, the machine is placed in its normal operating position according to 8.14.2.<br>
