ANDI - American Nitrox Divers International – Recreational diver training and certification agency, also ANDI International [6] EUF CB 2005005 [7] [8] ANIS - Associaziona Nazionale Istruttori Subacquei CMAS code ITA/F08 [2] ANMP - Association nationale des moniteurs de plongée – French recreational diver training and certification agency
As the first agency to offer recreational certification in nitrox, IANTD grew at a steady pace from 1985 through February 1992 with the support of Hyperbarics International. The European Association of Technical Divers (EATD) was formed by Kevin Gurr, Richard Bull, and Rob Palmer in the UK in 1992 and merged into IANTD the following year.
Technical Diving Instructor Trainer Courses TDI offers an instructor trainer workshop which is a 7-day program to achieve the greatest level of certification offered by the agency. Technical Divemaster Course The Technical Divemaster Course is the first step to achieving Leadership certification. Divemasters learn the physics involved in diving ...
The International Standard ISO 11107 Recreational diving services specifies the level of competence required of a scuba diver to be awarded an enriched air nitrox (EAN) diver certification by a training organization. These divers are competent to plan, conduct and log EAN open-water, single mixture, open-circuit no-decompression recreational ...

Advanced nitrox certification (Advanced nitrox diver) requires competence to carry two nitrox mixtures in separate scuba sets, and to use the richer mix for accelerated decompression at the end of the dive, switching gases underwater at the correct planned depth and selecting the new gas on the dive computer if one is carried. For the purposes ...
"Nitrox 32", or EAN 32, would be a nitrox blend with 32% oxygen and 68% nitrogen. This is a popular recreational blend for dives to depths up to 33 metres (108 ft). The nitrogen in the mixture is almost always provided by topping up the cylinder with air to the filling pressure.
Heliox or Nitrox with partial pressure not exceeding 3 ata may be used as treatment gas at pressures less than 165 fsw; 100% oxygen may be used as treatment gas at pressures less than 60 fsw; Decompression is done by 2 fsw pressure decrements unless the start depth is an odd number, in which case the first stop is at a 3 fsw reduction in pressure.
