Ну что ты все крутишся, как вошь на гребешке.
Приведи хоть одну цифру из
стандартов АНДИ 
Да я ж писал - это 62 страницы текста... ну вот малентький кусочек - читай наздоровье:
Вот выписка из последней редакции стандартов. В этом виде они существуют с 1990 года.
Если кто то может привести БОЛЕЕ жесткий стандарт своей конторы – с удовольствием почитаю и приму к сведению!
5.1 Gas Nomenclature & Specifications
Air is generally defined as 19 to 22 % Oxygen concentration by volume. (Compressed Gas Association
(CGA) standard is 19 to 23.5 %, while EUF definition is minimum 20% O2 ).
SafeAir® is defined as 22 to 50 % oxygen by volume and must match ANDI 's gas purity standard.
Compressed Gas Association standard definition of Oxygen Enriched Air is 23.5 to 50 % oxygen.
"NITROX" , "EAN" or "Enriched Air Nitrox" may be treated the same as SafeAir® mixtures by ANDI
members, however these other references may not meet ANDI's gas purity standard. ANDI's copyrighted
phrase illustrates our position ;
"Remember, it may be NITROX but if it is not ANDI, it's not SafeAir® ".
Oxygen mixtures are defined as 51 to 95 % oxygen by volume.
Oxygen is defined as 95 to 100 % oxygen by volume.
To breathe gases with an oxygen percentage between 22 to 50 percent, the equipment must be cleaned for
SafeAir® and maintained according to ANDI standards
To breathe gases with an oxygen percentage between 51 to 100 percent, the equipment must be cleaned
for SafeAir® and maintained according to ANDI standards AND be rated by the manufacturer for Oxygen
Service. Follow the manufacturer’s recommendations; in all cases they may replace ANDI standards.
5.2 Gas Production
1 Only persons who possess ANDI certification as a Certified Gas Blender may blend gas, produce
SafeAir® and produce gas mixtures other than air at any ANDI member facility. Any ANDI facility's
designated technician may dispense pre-mixed gas as if it were air into approved gas storage systems.
2 Any compressed air that will be mixed with oxygen must conform to the following standards:
a. Carbon monoxide no more than 2 part per million (ppm)
b. Carbon Dioxide no more than 500 ppm
c. Gaseous hydrocarbons no more than 25 ppm. Referenced as Methane ( CH4)
d. Condensed hydrocarbons no more than 0.1 mg / M3
e. Moisture/water vapor - dew point no greater than - 50 degrees C
f. Solid particles no greater than 2 microns
Since condensed hydrocarbon contaminates are cumulative, if any condensed hydrocarbons are
contained within the gas stream, a schedule of periodic maintenance and cleaning of the gas storage,
transfer and delivery equipment should be implemented.
3 Gas analysis is recommended for all gas dispensing facilities and is required quarterly for ANDI
facilities. The above mentioned standard limits are to be specified in the analytical report. These
reports are to be copied to ANDI regional HQ.
4 An ANDI facility may purchase pre-mix from another SafeAir® facility or other source for use in
their facility however ANDI gas standards must still be met.
5 A new ANDI facility will be given six-months to bring their gas production system and gas quality
into accordance with ANDI standards. Until the standards are met, they are not to advertise that they
produce SafeAir® (as this indicates a specific set of gas standards).

А вот взято из инета тоже к вопросу Дикого о том, кто у кого учился....:
«ANDI была первой обучающей организацией, разработавшей комплексную систему подготовки дайверов к использованию нитрокса (обогащенного воздуха). Конечно, нитрокс был изобретен и использовался профессиональными водолазами задолго до этого, и отдельные специалисты уже начинали обучать использованию нитрокса дайверов-спортсменов, но именно ANDI первая создала целую систему подготовки (учебники, стандарты, руководства для инструкторов, руководства для специалистов по приготовлению смесей), и с этого момента нитрокс начал свое победное шествие по миру.
Вообще ANDI имеет давнюю и славную историю. Достаточно сказать, что и Том Маунт (лидер IANTD), и Брет Гилльям (основатель TDI/SDI) были когда-то инструкторами ANDI…»
