Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are
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
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

AMENDMENT 1: Connectors
Clause 2
Add:
ISO 80369-7, Small-bore connectors for liquids and gases in healthcare applications — Part 7: Connectors
for intravascular or hypodermic applications
4.2.3 Connectors
Replace the text with the following:
Connectors for connection to the blood pathway shall, when tested in accordance with 5.3.3, allow a
secure connection.
NOTE 1 Connectors of a type that allows connection of tubes with an inner diameter of 4,8 mm, 6,3 mm, 9,5 mm
or 12,7 mm, or a type that complies with ISO 8637-1:2017, Figure 1, or a type that complies with ISO 80369-7 have
been found satisfactory.
NOTE 2 Connectors with dimensions as given in Annex A (formerly defined by ISO 594-1 and ISO 594-2) and
fitting to functional gauges and reference steel fittings is a way to be in accordance with this requirement.
Performance testing of the connectors shall be performed according to ISO 80369-7, Clause 6, using the
reference fittings given in Annex A.
