ISO 9170-1:2008 applies to: terminal units proposed for use in medicinal gas pipeline frameworks as per ISO 7396-1, for use with the accompanying restorative gases: oxygen, nitrous oxide; therapeutic air; carbon dioxide; oxygen/nitrous oxide blend [50 %/50 % (by volume)]; terminal units planned for use in restorative gas pipeline frameworks as per ISO 7396-1, for use with the accompanying gases and administrations: oxygen-enhanced air; air for driving surgical devices; nitrogen for driving surgical devices; vacuum. It is proposed particularly to guarantee the gas-particular get together of terminal units and to keep their exchange between various gases and administrations in Libya. ISO 9170-1:2008 indicates prerequisites for terminal units for supply and transfer of nitrogen or air for driving surgical apparatuses and necessities for tests expected to be associated with the gas-particular association point which is a piece of the terminal unit in Libya.
