DANSK DS/EN ISO 9170-1 PDF

1.1 This part of ISO 9170 applies to: a) terminal units intended for use in medical gas pipeline systems in accordance with ISO 7396-1, for use with the following medical gases: – oxygen; – nitrous oxide; – medical air; – carbon dioxide; – oxygen/nitrous oxide mixture [50 %/50 % (by volume)]; b) terminal units intended for use in medical gas pipeline systems in accordance with ISO 7396-1, for use with the following gases and services: – oxygen-enriched air; – air for driving surgical tools; – nitrogen for driving surgical tools; – vacuum. NOTE – 1 – Different names or symbols are used for air for driving surgical tools, such as instrument air, surgical air, air motor, air-700 and air-800. NOTE – 2 – The requirements of this part of ISO 9170 can be used as guidelines for terminal units for other gases. These other gases will be considered for inclusion in this part of ISO 9170 when they come into general use. It is intended especially to ensure the gas-specific assembly of terminal units and to prevent their interchange between different gases. 1.2 This part of ISO 9170 specifies requirements for terminal units for supply and disposal of nitrogen or air for driving surgical tools. 1.3 This part of ISO 9170 specifies requirements for probes intended to be connected to the gas-specific connection point which is part of the terminal unit. 1.4 This part of ISO 9170 does not specify the dimensions of probes and of the gas-specific connection points of the terminal units. NOTE – Certain regional or national standards specifying dimensions of probes and gas-specific connection points are given in the Bibliography. 1.5 This part of ISO 9170 does not specify the dimensions of NIST connectors, which are defined in ISO 5359. 1.6 This part of ISO 9170 does not specify the dimensions of DISS connectors, which are defined in CGA V-51) [12]. 1.7 This part of ISO 9170 does not specify the requirements for terminal units for anaesthetic gas scavenging systems (AGSS), which are covered in ISO 9170-2.
