Diving Computer Operational Envelope Proving Protocol Phase I. XDC-2 Validation Dives 0-54 MSW June/July 1979

摘要

The aim of this series of dives is to determine the operational envelope of the XDC-2 Decompression Computer using air to a maximum simulated depth of 54 metres of sea water. The objective is to evaluate the XDC-2 for operational diving, to determine whether the safe depth as displayed can be followed exactly for safe decompression, and to define the operational limits for it use. The basic dive profile is descent at 18 metres of seawater (msw) per minute to depth, remaining at that depth for the required time; initial ascent is at 18 msw/min. to the calculated safe depth, continuous ascent following the safe depth to 3 msw, a stop at 3 msw until the computer indicates that surfacing is possible, and then ascent to the surface. See Article 6.1 and Annex D and E for more detailed information with respect to ascent and descent times.
