Everything You Need to Know About VDE Certified Tools

Have you ever wondered what the letters VDE stand for on your insulated tools?

If you didn’t know, VDE is an acronym for Verband der Elektrotechnik. It’s the organization that’s responsible for testing and certifying tools and appliances. The VDE Testing and Certification Institute is renowned around the world for its assessment of electrical engineering devices, components, and systems.

But what testing does the VDE Testing and Certification Institute complete? How do they ensure that the tool you’re holding in your hands is going to protect you? If you want the peace of mind knowing you’ve got the right hardware for the job, then here’s what you need to know what your equipment goes through to get those three letters.

What Type of Certifications Are Available for Insulated Tools?

If you can’t find VDE imprinted on your insulated tools, then your equipment may have been certified by another organization. However, you should know there are some differences, and some don’t meet the same standards as VDE.


The American Society for Testing and Materials drafted its own standards in 1994 by using many of the same requirements as the International Electrotechnical Commission. It covers the designs and performance requirements for insulated tools as well as the testing specifications to achieve approval. Unfortunately, while it’s popular with products made in the United States, it doesn’t meet the same worldwide standards as other certifications.

IEC 60900 | BETTER

The International Electrotechnical Commission requirements cover dimensions, guards, and much more compared to ASTM F1505. It also specifies testing procedures to ensure that anyone using these tools is protected from accidental contact with voltages up to 1000 VAC. Tools approved by the IEC are recognized globally.


VDE certification manages to go above and beyond the IEC and ASTM specifications. The symbols stand for the product's safety regarding electrical, mechanical, thermal, taxological, radiological, and other dangers. In addition, it conforms to the VDE Testing and Certification Institute regulations and complies with the safety requirements of guidelines from around the world.

What are the VDE Certification Requirements?

Acquiring the VDE symbol isn’t easy. Manufactured insulated tools are subject to extensive testing before they’re certified.

What Type of Tests are Required?

There are several tests conducted on insulated tools to ensure they receive the VDE rating. The exams include the Voltage Piece Test, Cold Shock Test, Adhesion Test, Pressure Test, and Combustion Test. Each one is designed to ensure that anyone holding the tool is safe if they come into contact with voltages up to 1000 VAC.

Why is Certification Important?

Certification provides security to users of the tools. It’s proof that a piece of equipment has undergone strenuous testing, is designed according to detailed specifications and will keep a user safe in unforeseen circumstances.

Why is Certification from the VDE Institute Important?

The VDE symbol is recognized for having the highest safety standards and best protection for its consumers for over 100 years. The Institute provides detailed requirements concerning the design, manufacturing, and testing of any piece of hardware bearing its logo. As a result, it’s not only globally recognized, but internationally respected.
