The IEC 60900 standard is published by the International Electrotechnical Commission (IEC) and is widely adopted by utilities, contractors, and manufacturers around the world.
IEC 60900, titled "Live working - Hand tools for use up to 1 000 V AC and 1 500 V DC," is an international standard that specifies the requirements for insulated, insulating, and hybrid hand tools used for working live or close to live parts.

For insulated tools (like screwdrivers), the uninsulated conductive part at the tip must be kept to a minimum (often less than 15 mm) to prevent accidental short circuits.

| | Procedure | Purpose | | :--- | :--- | :--- | | Dielectric (Voltage) Test | The tool is submerged in water for 24 hours. Then, a test voltage of 10,000 V AC is applied between the metallic shaft and a water bath for 3 minutes. | To ensure there is no electrical breakdown or flashover, even in wet conditions. | | Cold Shock Test | The tool is conditioned at -25°C , and then the insulation is struck with a defined impact force. | To verify that the insulating material remains tough and does not become brittle or crack in cold environments. | | Adhesion (Pull) Test | The tool is stored at 70°C for 168 hours . A pull force of 500 N (approx. 50 kg) is then applied to the insulation handle. | To ensure the insulating layer does not separate from the metal shaft under high temperatures and stress. | | Pressure Test | Under a 20 N load at 70°C , a test voltage of 5,000 V is applied. | To guarantee insulation strength under mechanical pressure at high temperatures. | | Flame Retardancy Test | The tool's insulation is exposed to a flame for 10 seconds. | To ensure the insulating material is self-extinguishing and will not continue to burn and spread fire if exposed to an arc flash. |
The official, up-to-date version of the standard (currently IEC 60900:2018 or its latest amendment) should be purchased directly from authorized distributors. These include the , the International Organization for Standardization (ISO) , or national standards bodies like ANSI (USA), BSI (UK), or DIN (Germany). Purchasing authorized copies ensures you receive the complete text, including critical annexes, figures, and testing setup diagrams.

By following these recommendations, we can promote a culture of safety and efficiency in live working, reducing the risks associated with electrical hazards and ensuring a safer working environment for all.
This article provides a comprehensive overview of the standard, its testing requirements, marking compliance, and what professionals need to know when looking for an IEC 60900 PDF or compliance documentation. What is IEC 60900?
Although rated for 1,000 volts, tools must be tested at 10,000 volts to qualify for the official marking.
To meet IEC 60900:2018 standards, tools must pass a series of environmental and physical stress tests: Disclaimer: This article is for informational purposes

For insulated tools (tools made of metal but covered with insulating material), the standard defines exactly how much of the conductive metal can remain exposed at the working tip. For example, on an insulated screwdriver, only a minimal length of the tip is left bare to allow engagement with the screw, reducing the risk of accidental short circuits across adjacent live components. 3.
