The current german version can be downloaded here as a pdf: DGUV Regel 101-023 “Forschungstauchen”. A translated english version will follow soon.

In addition to the many editorial changes that make research diving even safer, we would like to draw your attention to the new set of tables for calculating dives. The new DGUV Rule 101-023 describes some case studies for handling. The old tables are no longer valid.
