Safety information
Today, test and measuring instruments are indispensable tools for building, repairing and maintaining electrical equipment and installations.
Modern test instruments are designed to provide fast, safe and reliable support for safety checks, troubleshooting and function tests.
International safety standards
The internationally valid safety standards for electrical equipment for measurement, control and laboratory use are drawn up and ratified by the IEC (International Electrotechnical Commission). It ensures that testing is carried out worldwide according to the same criteria and guidelines.
The currently valid standard is IEC/EN 61010-1. It replaced the older IEC/EN 348 in 1988 and forms the basis for the classification and testing of modern measuring instruments.
Testing by measurement category
4000 V peak impulse voltage, 12 ohm source
6000 V peak impulse voltage, 12 ohm source
6000 V peak impulse voltage, 2 ohm source
8000 V peak impulse voltage, 2 ohm source
8000 V peak impulse voltage, 2 ohm source
12000 V peak impulse voltage, 2 ohm source
Areas of application of the measurement categories
Measuring instruments are classified into different categories. These indicate the areas for which an instrument is approved.
Circuits that are directly electrically connected to the mains.
Sockets and long branch circuits.
All sockets more than 10 m away from CAT III.
All sockets more than 20 m away from CAT IV.
Building installations, e.g. distribution boards, wiring and sockets.
Feeder cables and short supply lines.
Distribution panels and sockets for large loads with short cables.
Lighting systems in large buildings, feeders and busbars.
Origin of the low-voltage installation, e.g. meters, main connection and primary overcurrent protection devices.
Outdoor areas and the supply cable feed.
Supply lines from the connection point to the building.
Connection between the meter and the connection point, overhead lines and underground cables.
Tested safety
To document that a product complies with IEC/EN 61010-1, it can be tested for conformity with the standard by an accredited test body. Once the test has been passed, the corresponding GS mark may be affixed to the product.
As a safety-conscious and responsible manufacturer, Testboy GmbH has selected products tested and certified by accredited test bodies such as TÜV SÜD or TÜV Rheinland.
