Authorities discovered the equipment in early August 2005, Interior Ministry spokesman Rudolf Gollia said, adding that a company in the southern province of Styria had tried to export it.
The equipment seized was a “friction tester” that is used to determine the sensitivity to friction of various substances, Gollia said. It was manufactured by a German company, he said.
He declined to provide more details, citing an ongoing investigation.
