ESD tools

The comprehensive ELORA range of pliers meets the requirements of professional users. The antistatic, ergonomic and slipresistant two-component handles faciliate safe guidance of the pliers and optimum transmission of force. ELORA ESD pliers are available with the most varied range of heads or jaws.

Production specifcation

The plier blanks are hot-forged in separate highprecision special dies within narrow tolerances. The result is a material quality which, because of its molecular structure, is far superior to punched or cold-formed blanks. We align the individual choice of materials according to the different demands of gripping or cutting pliers.

Gripping pliers are subject to torsional and bending forces as well as a greater stress on the surfaces and edges. Through the use of carbon steel C45, we achieve the optimum hardness value of 45 HRC.

Cutting pliers are highly stressed especially in the area of the cutting edges, apart from the torsional and bending forces. In order to ensure suffcient cutting edge hardness with high flexibility and load-bearing capacity, we use high-alloy steels between carbon steel C 60 and chrome-vanadium. The maximum cutting edge hardness is 65 HRC.

For the superior processing of extremely hard or tough materials, we equip a part of our side cutter and diagonal cutter range with carbide cutting edges. These are ideally suitable for cutting
through piano wire, nickel wire or diode wire as well as for glass fbre, which are being increasingly used in the electronics and aviation industry.

We achieve perfection of form and no-compromise cutting edge sharpness in the traditional handgrinding process – an impressive fnished look through the subsequent surface treatment or surface fnishing. Piece by piece.

FOLLOW THE SIGNS – TESTED SAFETY

The VDE GS symbolThis symbol indicates that the tools so marked have been tested for safety regarding potential hazards from electricity, physical danger, heat, radiation and other hazards.

The symbol is equivalent to the German VDE requirements and comparable with harmonised standards in the EU and around the world and confirms that the defined tolerance limits have been adhered to.

Double triangle and voltage rangeMarkings for insulated tools consisting of the double triangle show their suitability for work on electrical systems that are still “live”. The voltage or voltage range given shows the maximum safe load in volts.

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 approved 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 fluctuations in temperature. The test must not cause any of the insulation to crack, rupture or peel off.

3. Adhesion test

Even under high loads, the insulation material must remain firmly bonded 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
