Tool testing at ISOTOOLS

Testing according to VDE / IEC 60900:2012 / EN 60900:2012

Insulated VDE tools and tools with double triangle 1000V according to VDE/ IEC 60900:2012 / EN 60900:2012
are designed in accordance with the latest national and international standards
made of high-quality materials and tested.

If further safety measures are observed, they offer the greatest possible protection when live.
up to AC 1,000 volts (alternating voltage) and DC 1,500 volts (direct voltage).

REACH and PAH regulation at


As part of our commitment to product safety and consumer health
-products meet REACH requirements and withstand PAH testing.

REACH – Registration, Evaluation, Authorization, Restriction of Chemicals

  • EU Chemicals Regulation
  • Valid in all member states
  • All chemical substances are registered
  • The main objectives are: Ensuring a high level of protection of human health and the environment from possible chemical-related risks; promoting alternative test methods; the free movement of chemicals in the internal market and improving competitiveness and innovation.
  • REACH makes industry responsible for assessing and limiting risks from chemicals and providing users with appropriate safety information.
  • At the same time, the EU can adopt additional measures for highly hazardous substances if these are necessary at EU level.

PAH test = polycyclic aromatic hydrocarbons

  • Mandatory for the GS mark
  • PAHs are carcinogenic:
    is found in plasticizer oils, which are used for rubber parts and plasticized plastics.
  • These fat-soluble compounds can enter the body through the skin
    and are considered “carcinogenic”.

Voltage test

The dip-insulated tools are piece-tested.
The double triangle marking indicates that the tools have been tested with AC 10,000 V and are therefore approved for live working up to 1,000 V. This guarantees 10-fold safety. This guarantees 10-fold safety.

Cold impact test

The toughness of the PVC material is tested by dropping a weight onto the tools which have been cooled to -25°C.
There must be no cracks or damage afterwards.

Testing the electrical insulation properties

After 24 hours of underwater storage, the tools are heated with AC 10,000 V
– with simultaneous testing of the leakage current – tested for three minutes.
During this time, neither a breakdown nor a flashover may occur.

Pressure test

At a pressure load of 20 Nm and a temperature of 70°C, no breakdown may occur when testing with a voltage of AC 5,000 V.

Testing the adhesion of the PVC coating

For pliers, the adhesion of the PVC coating is tested after storage for 168 hours at 70°C with a tensile force of 500 Nm.
The insulating material must remain firmly attached to the basic tool.

Testing the flame resistance

To eliminate the risk of fire, only flame-retardant and self-extinguishing PVC material is used.
