IEC 60745-2-5 IEC Test Equipment For Guarding Below The Guide Plate

IEC 60745-2-5 Circular Saw Lower Guard Test Device, 0-30 times / min

IEC 60745-2-5 clause 19.102.3 For saws having a blade with a diameter less than 210 mm, the closing time of the lower guard from the fully open position to the fully closed position shall not exceed 0,2 s. For saws having a blade diameter 210 mm and above, the closing time of the lower guard from the fully open position to the fully closed position in seconds, shall be less than the numerical equivalent of the largest recommended blade diameter, expressed in metres, but not more than 0,3 s. During measurement, the saw is set to cut at a right angle and for maximum cutting depth, with the guide plate in the horizontal position and the saw not inverted.
Compliance is checked by measurements.

Standard: IEC 60745-2-5 : Particular requirements for circular saws, clause 19.102.3 and Annex BB, EN 60745-2-5, IEC 62841-2-5 clause 17.101

Application: This device is applicable to test the closing time and mechanical strength of lower guard for circular saws.

Test sample: Circular saws IEC Test Equipment

Feature: The saw is to be set for a 90°cut and oriented in the horizontal plane. The lower guard is to be cycled from the full closed position to the maximum open working position and then released for 50000 cycles at a rate not less than 10 cycles per minute. The cycle numbers recorded by a position sensor. Following the cycle, the closure time shall not exceed 0.3s. The device record the times when detected closure time exceed 0.3s. When preset test times completed, device record the last closure time and stop automatically.
