ISO 9170-1:2008

Terminal units for medical gas pipeline systems - Part 1: Terminal units for use with compressed medical gases and vacuum

ISO 9170-1:2008 applies to:

1. 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)];
2. 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.

It is intended especially to ensure the gas-specific assembly of terminal units and to prevent their interchange between different gases and services.

ISO 9170-1:2008 specifies requirements for terminal units for supply and disposal of nitrogen or air for driving surgical tools and requirements for probes intended to be connected to the gas-specific connection point which is part of the terminal unit.
