VDE test
Hand tools for live working up to 1000 V A.C. and
1500 V D.C. The VDE hand tools is in accordance to
European standard EN 60900. Agenda: A.C -
alternating current D.C. - direct current Every
insulated hand tools is tested individual on the end of
production process.
 |
Stamp test
The indenter is loaded with a weight of 20N and
is applied to the centre of the handle. The test
is successful if the test piece subsequently
passes the electrical test. |
|
Flame retardancy
test
The flame is applied to the test piece
for 10 seconds. The test piece is acceptable if
the height of the flame on the burning handle
does not exceed 120 mm in an observation period
of 20 seconds after the burner has been removed. |
 |
 |
Impact test
The test is carried out at an ambient
temperature of 23°C. The hammer is allowed to
fall freely on the test piece 3 times. The test
piece is acceptable if the handle is not
cracked, broken or does not show signs of
flaking.
|
|
Insulation test
Before testing the test piece is heated
to 70 C -/+ 2° C for 168 hours. The hanger is
loaded with weights (500 N). The duration of
test is 3 minutes. The test piece is acceptable
if the handle remains firmly attached to the
conducting part. |
 |
 |
Electrical test (10kV)
Before testing the tools are immersed
in a bath of water at 23° C for 24 hours +- 5
hours. The test pieces are acceptable if there
is no electrical discharge, spark over or
flashover, and if the current leakage is less
than 1mA for 20 mm insulation.
|
Safety recommendation:
If the insulating material on insulated tools shows
damage (exfoliations, cracks) you have never use them
for working on live
