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

ISO 9170-1:2017 is intended especially to ensure the gas-specific assembly, mechanical resistance, flow, leakage and pressure drop of terminal units and to prevent their interchange between different gases and services and applies to terminal units:

a) intended for use in medical gas pipeline systems in accordance with ISO 7396 1;

b) used as pressure outlets on pressure regulators in accordance with ISO 10524 1;

c) used as pressure outlets on pressure regulators integrated with cylinder valves (VIPR) in accordance with ISO 10524 3.
