the following engineering and test services:
Devices and equipment, which are developed and produced • Lightning current tests, for example for equipotential

page at www.dehn-international.com. The DEHN test laboratory is equipped with high-perfor-
mance devices. Tests are carried our in line with the latest
national and international standards. Thanks to our rep-
resentation in standardisation committees over decades, our
employees are always familiar with the latest standards and
have in-depth knowledge of technical basics. We use this
knowledge to carry out our engineering and test services,
thus making our protection concepts feasible for applica-
tions in the gas industry.
