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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the

ISO 7886-3 was prepared by Technical Committee ISO/TC 84, Devices for administration of medicinal
products and catheters.
In some countries national regulations are legally binding and the requirements may take precedence
over this International Standard.
This second edition cancels and replaces ISO 7886-3:2005, which has been technically revised.
ISO 7886 consists of the following parts, under the general title Sterile hypodermic syringes for single use:
— Part 1: Syringes for manual use
— Part 2: Syringes for use with power-driven syringe pumps
— Part 3: Auto-disabled syringes for fixed-dose immunization
— Part 4: Syringes with re-use prevention feature
The main changes to the previous edition of ISO 7886-3 introduced by this revision are:
Change in scope of the standard: Upon commencement of injection of a nominal fixed dose of vaccine,
the auto-disable feature of the syringe is passively activated so that the syringe cannot be reused.
ISO/DIS 7886-3:2016(E)
Introduction
ISO 7886 was first published in 1984. It was subsequently decided to divide it into two parts, ISO 7886-1
retaining essentially the scope of ISO 7886:1984, and ISO 7886-2 being applicable to sterile, single-use
syringes for use with power-driven pumps.
The preparation of this third part of ISO 7886 was recognized as a high priority requirement to prevent
the re- use of fixed dose immunization syringes in the developing and transitional countries. Re-use of
injection equipment in the absence of sterilization has increasingly led to transmission of blood-borne
pathogens.
The World Health Organization had produced a specification for syringes that are rendered inactive
after one use (commonly referred to as “auto-disabled” syringes). Both the WHO and ISO agreed that an
additional part of ISO 7886 would be required to cover “auto-disabled” syringes, whilst leaving in place
ISO 7886 Parts 1 and 2 without modification, as a large number of devices in common use would not be
intended to comply with the auto-disable properties suggested.
This part of ISO 7886 is intended to cover “fixed dose” immunization syringes that are passively
rendered non-reusable for another application after the commencement of injection intended to deliver
a nominal vaccine dose. These syringes are not covered by Parts 1 and 2 of ISO 7886.
Based on field feedback, the World Health Organization recommended to make further amendments to
this standard for enhanced safety and to bring more clarification to requirements. These amendments
are covered in this revision of this standard.
It is recognized that syringes designed to reduce the risk of needle stick injuries, may also comply with
this part of ISO 7886 with regard to their auto-disable properties, but it is stressed that needle stick
protection features of syringes are not in themselves addressed in this part of ISO 7886. Requirements
for sharps injury protection features are covered by ISO 23908.
Guidance on transition periods for implementing the requirements of this standard is given in
ISO/TR 19244 ‘Guidance on transition periods for standards developed by ISO/TC 84 - Devices for
administration of medicinal products and catheters’.

DRAFT INTERNATIONAL STANDARD ISO/DIS 7886-3:2016(E)
Sterile hypodermic syringes for single use —
Part 3:
Auto-disabled syringes for fixed-dose immunization
1 Scope
This part of ISO 7886 specifies the properties and performance of sterile single-use hypodermic syringes
with or without needle, made of plastic or other materials and intended for the filling and the injection of
vaccines immediately after filling. Upon commencement of injection of a nominal fixed dose of vaccine,
the auto-disable feature of the syringe is passively activated so that the syringe cannot be reused.
This part of ISO 7886 does not specify the design of the auto-disable feature, which is left to the
discretion of the manufacturer.
This part of ISO 7886 is not applicable to syringes for use with insulin (specified in ISO 8537), syringes
for use with power-driven syringe pumps (specified in ISO 7886-2), reuse prevention syringes
(specified in ISO 7886-4) and syringes designed to be prefilled. It does not address compatibility with
injection fluids/vaccines.
NOTE Prefilled syringes are covered under ISO 11040- series.
