General Programme 2021

The ۸ spark-proof tools are specially designed for safe operations in environments subject to potential risk of explosion, in the presence of flammable liquids or gases, or for any applications that require using perfectly antimagnetic, corrosion-resistant tools. Copper-Berillium Cu-Be

proof tools are certified by the The Beta spark tute for Materials Research Federal Insti AM, under European Directive and Testing, B 99/92/EC.
