电动打草机防护罩安规
请问各位电动打草机的防护罩的安规尺寸是多少,有个多少度的最小尺寸限制,其它的尺寸有没有限制,谢谢 哥,请先说出哪边的撒,根据IEC 60335-2-91:2008如下要求20.101.1 Lawn trimmers
Lawn trimmers shall be guarded on the operator’s side, as a minimum, to the extent shown
in Figure 101.
The radius X of the guard shall not be smaller than the major swept radius of the cutting
head and the guard shall extend beyond the plane of the cutting element by at least 3 mm
for walk-behind lawn trimmers and 10 mm for hand-held lawn trimmers. The guard shall
extend at least 45° from the axis of the handle on the side where the cutting element is
moving away from the operator and at least 90° from the axis of the handle on the side where
the cutting element is moving towards the operator. The vertices of these angles lie on the
axis of the cutting head spindle.
If the guarding is less than a total of 360°, the direction of rotation of the cutting element(s)
shall be marked on the lawn trimmer.
Compliance is checked by inspection and measurement.
20.101.2 Lawn edge trimmers
Lawn edge trimmers shall be guarded, as a minimum, to the extent shown in Figure 102.
The radius X of the guard shall not be smaller than the major swept radius of the cutting
head. The guard shall extend beyond the plane of the cutting element by at least 10 mm.
With the lawn edge trimmer in its normal position of use, the guard shall extend a minimum
of 90° from the vertical towards the ground on the side where the cutting element is moving
upwards and a minimum of 45° from the vertical towards the ground on the side where the
cutting element is moving downwards. The vertices of these angles lie on the axis of the
cutting head spindle.
If the guarding is less than a total of 360°, the direction of rotation of the cutting elements
shall be marked on the lawn edge trimmer. 谢谢这位兄台 学习了。
