Nitrox (EAD) tables
NDTT reccomends the use of standardized gas mixtures when diving Nitrox, i.e. 32%, 36% and 40%. There may however be situations in which the gas manufacturer delivers gas outside gas specification (+/- 0,5%). In these cases there is a need for EAD tables relevant for the specific oxygen fraction. A complete set of EAD tables covering oxygen fractions between 25% and 45% may be downloaded from this link. The tables are provided for a 1% nominal increase in FO2 within this range.
