Test finger nail is mainly used for the puncture-proof test of the accessible part of the solid insulation, also it is used to test whether the non-removable parts of an electric shock or release moving part are able to withstand the mechanical stresses that occur during normal use.
2. Specification:
1). Finger nail probe is consisted by fingertip, middle finger, finger seat.
2). Force applied: 10N, 20N, 30N, 40N, 50N
3). Application: a) Applied 10N force to the surface of scratch test, the material of the scratched surface cannot be separated. b) Use the test finger nail to insert any gap or joint, apply a 10N side force vertically, but do not to twist and sway, the relevant parts can not fall off or damage. c). Use the test finger nail to insert any gap or joint, apply a 10N side force in the direction of component disassembly, but do not twist and sway, the relevant parts can not fall off or damage.
