K.12.1 Battery machines and battery packs shall not attain excessive temperatures.Compliance is checked by determining the temperature rise of the various parts under the following conditions:The test is conducted with the machine placed on an unperforated flat horizontal surface with the cutting means attached. The traction drive wheels, if any, are lifted the minimum amount required to avoid contact with the unperforated flat horizontal surface.The most unfavourable conditions are determined using the configuration of– attachments;– cutting means;– batteries; and– control settings (e.g. cutting means or traction drive on/off)in accordance with K.8.14.2, which yields the highest temperature on the surface of the external enclosure when evaluated at both minimum and maximum cutting height.The machine is operated continuously at no-load– at maximum speed; and– with the traction drive, if any, adjusted to its most unfavourable speed setting, including zero speeduntil maximum temperature is reached or the machine no longer operates due to the batterybeing discharged.During the test, protective devices shall not operate. The temperature rises shall not exceed the values shown in Table 2.K.12.2.1 This subclause of Part 4-3 is not applicable.
