Safety checks to IEC standards
using a pair of ELORA pliers as an example
1. Voltage test
ELORA VDE tools are individually tested to 10,000 V AC and are ap-
proved for work in systems carrying a live voltage of up to 1,000 V AC
or 1,500 V DC.
2. Impact test
The insulating material of ELORA VDE tools is subjected to an impact
test. At an ambient temperature of +23 °C and after storage for 2 hours
at -25 °C, an impact test is performed to see whether the insulation
material can withstand jolts and impacts after being subjected to these 07
fluctuations in temperature. The test must not cause any of the insula-
tion to crack, rupture or peel off.
3. Adhesion test
Even under high loads, the insulation material must remain firmly bond-
ed to the tool. First, the tool is stored for 168 hours at a temperature of
70 °C. Then the adhesive strength of the insulation material is subjected
to a tensile force of 500 N.
4. Testing resistance to fire
A test flame is aimed at the tool for a duration of 10 seconds. Once the
flame is removed, the flame emitted by the insulation must not exceed
120 mm for a period of 20 seconds.
5. Pressure test
After being stored for 2 hours at 70 °C, the insulation material of the
ELORA VDE tools is subjected to a compressive force of 20 N and a
testing voltage of 5,000 V AC for three minutes. During this time, there
must be no disruptive discharge or arcing on the surface or in the air.
