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 23908 was prepared by Technical Committee ISO/TC 84, Devices for administration of medicinal
products and intravascular catheters.

ISO 23908:2011(E)
Introduction
This International Standard addresses sharps injury protection systems designed to protect users of medical
devices. These sharps injury protection features are intended to prevent, or reduce the potential for, disease
transmission which could result from accidental, post-use sharps injuries.
This International Standard is aimed at addressing devices primarily intended for human use, of a wide range
of product types, including, among others, hollow-bore needles for injection or infusion of therapeutics into the
body, or sampling of fluids from the body, and hollow bore or solid-core needles used for blood sampling
(e.g. lancing devices). It addresses sharps injury protection systems which are either active or passive in their
activation after the medical device's intended use. It does not cover solid-core needles used for surgery
(e.g. suture needles).
Given the broad variation in product design and sharps protection technology, the variety of different types of
devices, and in order to avoid unnecessarily restricting innovation, this International Standard has been
developed as “horizontal” in nature, which means it provides for general design, testing and labelling
requirements, rather than specific physical and prescriptive design requirements. It therefore differs from more
“vertical” standards, which list specific maximum forces, detailed test fixture designs, test systems to be used
or detailed test measures, as such prescriptive details cannot cover the variety of designs and devices, and
may impede continuing innovation in new products, features and/or protection mechanisms that lead to future
improvements in healthcare.
This International Standard presumes that the product developer would use a risk-based approach (consistent
with ISO 14971) to determine the device design that best meets the needs of a target user population and
expected use settings. Through this risk-based approach, the sharps injury protection system would have
performance requirements appropriate to the foreseeable risks associated with the intended use of the device,
expected user interfaces, and the settings in which these safety features are expected to be used.
This International Standard provides guidelines to enable the manufacturer to verify that the design of the
sharps injury protection systems complies with the design intent spelled out in the design specification. As part
of this verification, the manufacturer is expected to demonstrate that the performance of the sharps injury
protection system is appropriate to the intended users and settings through the use of appropriate simulated
or clinical use studies. These simulated or clinical use studies allow the manufacturer to demonstrate that,
when used in accordance with the instructions for use, in settings representative of real-life intended use and
by intended or foreseeable users, the device functions as intended.
Existing products and those currently under development may not fulfil some of the requirements given by this
International Standard. However, manufacturers would be well advised to follow its provisions when improving
existing products or developing new products to obtain an even higher level of quality.

INTERNATIONAL STANDARD ISO 23908:2011(E)

Sharps injury protection — Requirements and test methods —
Sharps protection features for single-use hypodermic needles,
introducers for catheters and needles used for blood sampling
1 Scope
This International Standard gives requirements and test methods for evaluating the performance parameters
of sharps injury protection features, whether active or passive in design, for medical devices containing
(sharp) hypodermic needles for single use, introducers for catheters and lancets, and other needles used in
blood sampling. The sharps injury protection devices it covers may be provided integral to the device or
combined with the device prior to use to achieve the sharps injury protection.
It does not give requirements for the storage and handling of the sharps protection before its intended use, or
for the medical device itself.
