DEVELOPMENT OF THE INTERNATIONAL STANDARD ON LIFE SUPPORT SYSTEMS FOR SPACEFLIGHT
The International Organization for Standardization approved a three-level standard structure developed by Russian specialists on human integration with the life support (LSS) systems and equipment in a spaceflight, and prepared working revisions of three draft standards (one for each level). Such approach makes it possible to rapidly develop and coordinate separate standards for each type of habitability in a spaceflight. Russia being a prime developer of these standards gets a priority in the area of LSS standardization.
Key words: human being, spaceflight, habitation environment, life support system, international standards.
