ISO 13293 provides minimum training standards for gas blenders for recreational diving services at two levels. Level 1 gas blender is competent to blend nitrox and handle oxygen, air and nitrox, i.e. nitrox gas blender, and a level 2 gas blender is also competent to mix gases containing helium and argon, i.e, a trimix gas blender.

For example, based on the PADI nitrox recommendations, the maximum operating depth for EAN45 would be 21 metres (69 ft) and the maximum dive time available at this depth even with EAN36 is nearly 1 hour 15 minutes: a diver with a breathing rate of 20 litres per minute using twin 10-litre, 230-bar (about double 85 cu. ft.) cylinders would have ...
ISO 11107 Enriched air nitrox (EAN) diving (PADI equivalent – Enriched Air Diver) ISO 11121 introductory training programs to scuba diving. (PADI equivalent – Discover Scuba Diving) Most PADI training programs are not directly covered by ISO standards.
The PADI Nitrox tables are laid out in what has become a common format for no-stop recreational tables Video: Setting the bezel of a diving watch to the start time (minute hand) of a dive at the beginning. Divers used this in conjunction with a depth gauge and a decompression table to calculate the remaining safe dive time (or required stops ...
In 1992 Tom Mount became the President and CEO, and the name of the organization was changed to the International Association of Nitrox and Technical Divers (IANTD). Billy Deans has also served as a director of IANTD. Prior to founding IAND, Rutkowski worked for Dr Wells and was director of the diver training at NOAA.
Nitrox is generally understood as air enriched by additional oxygen, as that is the usual method for producing it. Gas fraction of oxygen may range from 22% to 99%, but is more usually in the range of 25% to 40% for bottom gas (breathed during the main part of the dive), and 32 to 80% for decompression mixtures.
American Nitrox Divers International (or ANDI) was founded by Ed Betts and Dick Rutkowski in 1988. [1]ANDI has since expanded to include offices in The United Kingdom, Israel, Australia, Sweden, Italy, Germany, The Netherlands, Greece, Japan, Taiwan, Republic of Korea, Republic of Maldives, Republic of Philippines, Latin America, Middle East, with its home office in the United States of America.
SDI's philosophy is to improve recreational scuba diving training, enhancing older diving practices by incorporating new diving technology and emphasizing safety. [8] The curriculum is set up to take divers from the beginner level to instructor level and structures its courses around a logged dive and specialty course approach. [ 9 ]
