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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 1135-4 was prepared by Technical Committee ISO/TC 76, Transfusion, infusion and injection, and blood
processing equipment for medical and pharmaceutical use.
This sixth edition of ISO 1135-4 together with ISO 1135-5, first edition, cancels and replaces the fifth edition
(ISO 1135-4:2012), of which the scope has been restricted to gravity feed and the whole document aligned
accordingly. Transfusion sets for single use used in conjunction with pressure infusion apparatus are now
covered by ISO 1135-5.
ISO 1135 consists of the following parts, under the general title Transfusion equipment for medical use:
 Part 3: Blood-taking set
 Part 4: Transfusion sets for single use, gravity feed
 Part 5: Transfusion sets for single use with pressure infusion apparatus

DRAFT INTERNATIONAL STANDARD ISO/DIS 1135-4

Transfusion equipment for medical use — Part 4: Transfusion
sets for single use, gravity feed
1 Scope
This part of ISO 1135 specifies requirements for single use transfusion gravity sets for medical use in order to
ensure their compatibility with containers for blood and blood components as well as with intravenous
equipment.
Gravity feed is here defined as unassisted gravity or positive pressure up to 30 kPa. However sets with an
elastomeric buffer (optional) are only rated to 20 kPa.
Secondary aims of this part of ISO 1135 are to provide guidance on specifications relating to the quality and
performance of materials used in transfusion sets, to present designations for transfusion set components and
to ensure the compatibility of sets with a range of cellular and plasma blood components.
In some countries, the national pharmacopoeia or other national regulations are legally binding and take
precedence over this part of ISO 1135.

3.3 Designation
A transfusion set complying with the requirements of this part of ISO 1135 is designated as follows:
Transfusion set ISO 1135-4
4 Materials
The materials from which the transfusion sets given in Clause 3 are manufactured shall comply with the
requirements specified in Clause 5. If components of the transfusion set come into contact with blood and
blood components, they shall additionally comply with the requirements specified in Clauses 6 and 7.
5 Physical requirements
5.1 Particulate contamination
The transfusion sets shall be manufactured under conditions that minimize particulate contamination. All parts
shall be smooth and clean at the fluid pathway surfaces. When tested as specified in A.1, the number of
particles detected shall not exceed the contamination index limit.
5.2 Leakage
The transfusion set, when tested in accordance with A.2, shall show no signs of air leakage.
5.3 Tensile strength
Any connections between the components of the transfusion set, excluding protective caps, shall withstand a
static tensile force of not less than 15 N for 15 s.
5.4 Closure-piercing device
5.4.1 The dimensions of the closure-piercing device shall conform to the dimensions shown in Figure 2.
NOTE The dimension of 15 mm in Figure 2 is a reference measurement. The cross-section of the piercing device at
this site is a circle.
Dimensions in millimetres

Figure 2 — Dimensions of the closure-piercing device
5.4.2 The closure-piercing device shall be capable of piercing and penetrating the closure of a container for
blood and blood components without prepiercing. No coring should occur during this procedure.
NOTE 1 A carefully controlled surface treatment of the closure-piercing device (e.g. siliconization) is recommended to
facilitate its insertion into the blood bag port. The same effect may be achieved by a careful selection of material for the
closure-piercing device. Typical results including test equipment for penetration forces between spikes and blood bag
ports have been published. See References [11] and [12].

The drip chamber shall permit continuous observation of the fall of drops. The liquid shall enter the drip
chamber through a tube which projects into the chamber. There shall be a distance of not less than 40 mm
between the end of the drip tube and the outlet of the chamber, or a distance of not less than 20 mm between
the drip tube and the filter for blood and blood components. The wall of the drip chamber shall not be closer
than 5 mm to the end of the drip tube. The drip tube shall be such that 20 drops of distilled water at (23 ± 2) °C
and at a flow rate of (50 ± 10) drops/min deliver (1 ± 0,1) ml [(1 ± 0,1) g].
The drip chamber should permit and facilitate the procedure of priming.
5.8 Flow regulator
The flow regulator shall adjust the flow of the blood and blood components between zero and maximum.
The flow regulator should be capable of continuous use throughout a transfusion without the tubing being
damaged. There should be no deleterious reaction between the flow regulator and the tubing when stored in
such a manner that there is contact.
5.9 Flow rate of blood and blood components
The transfusion set shall deliver not less than 1 000 ml of blood at (23 ± 2) °C in 30 min with a pressure
difference of 10 kPa. The transfusion set shall also deliver not less than 500 ml of blood in 2 min under a
pressure of 30 kPa above atmospheric pressure.
The blood shall be collected into a suitable anticoagulant solution and stored for not less than 2 weeks, and be
free of large clots.

applicable, activated or inactivated) by passage through the set (see Note). The assessment should compare
using a validated test method, samples of the blood component taken prior to and after passage through the
transfusion set.
The clinical relevance of test results should be determined by a competent accredited laboratory.
