IEC 60335-1 Figure 7 Test Finger Nail With 50N 

Product Overview:

The test fingernail confirms to the standard of IEC60335-1 clause 21.2, clause 22.11, Figure 7, etc. It is used to test non-detachable parts that protect against access to live parts, moisture or contact with moving parts shall be fixed in a reliable manner and withstand the mechanical stress occurring during normal use. Snap-in devices used for fixing such parts shall have an obvious locked position. It is dispensable for the electrical testing departments.

 

Technical Parameters:

 

Probe material Stainless steel
Handle material Nylon
Applied force Built-in 10N, 20N, 30N, 40N, 50N
Probe length 80 mm
Angle of the finger nail 37°
Diameter of the test finger Φ12 mm
 
The test fingernail consists of fingernail, finger body, stop plate, thrust block and pull-tab, thrust block can offer thrust of 0~50 N (resolution: 5N). The dimensions are coincided with that shown in following standard figure.
IEC 60335 Clause 22.11 Figure 7 Test Finger Nail With 50N Built - In Force 0
IEC 60335 Clause 22.11 Figure 7 Test Finger Nail With 50N Built - In Force 1
Test Procedures and Operation:
 

Please refer to the relevant standards.

Take IEC60335-1 clause 21.2 as an example:

The test fingernail of Figure 7 is then applied to the scratched surface with a force of approximately 10 N.

The force is applied by pushing the top surface of the handle to the specific force scale line.

Notice:

1. Please do not damage the appliance shape (such as scratching, bending, etc.).

2. Prevented from dust and moisture environment, in order to avoid the oxidation to affect the dimensional accuracy.

3. Be careful of electric shock.
