ISO 5359 AMD 1: Third Edition
SDO: ISO: International Organization for Standardization
DOD Adopted ANSI Approved Approved
* This International Standard specifies requirements for low-pressure hose assemblies intended for use with the following medical gases:
— nitrous oxide;
— medical air;
— carbon dioxide;
— specified mixtures of the gases listed above;
— oxygen-enriched air;
— air for driving surgical tools;
— nitrogen for driving surgical tools;
It is intended in particular to ensure gas-specificity and to prevent cross-connection between systems conveying different gases. These hose assemblies are intended for use at maximum operating pressures of less than 1 400 kPa.
This International Standard specifies the allocation of (NIST), (DISS), (SIS) connectors to medical gases and specifies the dimensions of non-interchangeable screw-threaded (NIST) connectors.
This International Standard does not specify:
— requirements for coaxial hoses used for the supply and disposal of air for driving surgical tools;
— requirements for electrical conductivity.
This International Standard does not specify the intended uses of hose assemblies.
NOTE Some examples of intended use specified in other International Standards are as follows:
between a terminal unit and medical equipment (ISO 9170-1, IEC 60601-2-12, IEC 60601-2-13);
between the fixed pipeline system and a terminal unit of that system (ISO 7396-1, ISO 11197);
between a terminal unit and a second terminal unit (ISO 7396-1);
between an emergency supply and an emergency and maintenance inlet point of a pipeline system (ISO 10524-1, ISO 7396-1);
between an emergency supply and medical equipment (ISO 10524-1, ISO 10524-3, IEC 60601-2-12, IEC 60601-2-13).
