Annex ZA
(informative)

Relationship between this European Standard and the Essential
Requirements of EU Directive 93/42/EEC
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association to provide one means of conforming to Essential Requirements of
the New Approach Directive 93/42/EEC.
Once this standard is cited in the Official Journal of the European Union under that Directive and has been
implemented as a national standard in at least one Member State, compliance with the normative clauses of
this standard given in Table ZA.1 confers, within the limits of the scope of this standard, a presumption of
conformity with the corresponding Essential Requirements of that Directive and associated EFTA regulations.
NOTE When an Essential Requirement does not appear in Table ZA.1, it means that it is not addressed by this
standard.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the

Introduction
This International Standard specifies dimensions and requirements for suction catheters for use in the
respiratory tract. It is concerned with the basic requirements and method of size designation of both
open and closed suction catheters made of flexible materials.
The method of describing tube dimensions and configuration has been devised in order to assist clinicians
in the selection of the most suitable suction catheter for a particular patient. Size is designated by
outside diameter which is important when selecting a catheter because of its relationship to the ease
[2][3][4]
with which the catheter can be passed through a tracheal or tracheostomy tube.
Revisions in this fourth edition are intended to harmonize this International Standard with recent
amendments in the European Medical Device Directive.
Major technical revisions in this edition include requirements for closed suction catheters, new
requirements to harmonize this International Standard with requirements for critical care ventilators,
and risk management.
[1]
Terms defined in Clause 3 of this International Standard or in ISO 4135 appear in bold type.
Throughout this International Standard, text for which a rationale is provided in Annex A is indicated

Suction catheters for use in the respiratory tract
1 Scope
This International Standard specifies requirements for suction catheters, including closed suction
catheters, made of flexible materials and intended for use in suctioning of the respiratory tract.
Angled-tip suction catheters (e.g. Coudé catheters) and suction catheters with aspirator collectors are
not considered to be specialized and are therefore included in the scope of this International Standard.
Suction catheters intended for use with flammable anaesthetic gases or agents, lasers or electrosurgical
equipment are not covered by this International Standard.

NOTE See ISO/TR 11991 for guidance on airway management during laser surgery of the upper airway.
