BS EN ISO 9170-1:2008

Terminal units for medical gas pipeline systems. Terminal units for use with compressed medical gases and vacuum | Status: Superseded, Withdrawn

1 Scope 1.1 This part of ISO 9170 applies to:

1. 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)];
2. 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 and services.
