CAN/CSA Z5359-10 (R2015) Historical

Preface

This is the second edition of CAN/CSA-Z5359, Low-pressure hose assemblies for use with medical gases, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 5359 (third edition, 2008-06-15). It supersedes the previous edition, published in 2004 as CAN/CSA-Z5359 (adopted ISO 5359:2000).

Scope

1.1 * This International Standard specifies requirements for low-pressure hose assemblies intended for use with the following medical gases:
- oxygen;
- nitrous oxide;
- medical air;
- helium;
- carbon dioxide;
- xenon;
- specified mixtures of the gases listed above;
- oxygen-enriched air;
- air for driving surgical tools;
- nitrogen for driving surgical tools;
- vacuum.

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.

1.2 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.

1.3 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.

1.4 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:

a) between a terminal unit and medical equipment (ISO 9170-1, IEC 60601-2-12[7], IEC 60601-2-13[8]);
b) between the fixed pipeline system and a terminal unit of that system (ISO 7396-1[10], ISO 11197[13]);
c) between a terminal unit and a second terminal unit (ISO 7396-1);
d) between an emergency supply and an emergency and maintenance inlet point of a pipeline system (ISO 10524-1[12], ISO 7396-1);
e) between an emergency supply and medical equipment (ISO 10524-1, ISO 10524-3[16], IEC 60601-2-12, IEC 60601-2-13). See more
