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).

ISO 11608-4:2022(E)
Introduction
Needle-based injection systems, including on-body delivery systems (OBDSs), containing electronics
with or without software, are primarily intended to administer medicinal products to humans.
Performance requirements regarding essential electrotechnical aspects have been selected with the
intention not to restrict the Electronic Needle-based Injection System (NIS-E) design unnecessarily
when applying the document.
The first edition of this document was limited to pen-injectors with electromechanical drive. Pen-
injectors only equipped with electronics were covered in ISO 11608-1.
Materials used for construction are not specified in this document, as their selection will depend on the
design, the intended use and the process of manufacture used by individual manufacturers.
There are other international and national standards and guidance publications and, in some countries,
national regulations that are applicable to medical devices and pharmaceuticals. This document is
applicable to NIS-E and specifies relevant aspects of IEC 60601-1:2005+AMD1:2012+AMD2:2020,
IEC 60601-1-2:2014+AMD1:2020 and IEC 60601-1-11:2015+AMD1:2020 for this particular device type.
This document does not specify non-electrotechnical requirements and test methods for NISs when
specified by ISO 11608-1.
Developers and manufacturers of NIS-Es are encouraged to investigate and determine whether there
are any other requirements relevant to the safety or marketability of their NIS-Es. For example, this
document should be used in conjunction with IEC 60601-1, IEC 60601-1-2 and IEC 60601-1-11. A risk-
based approach is expected to be applied during the design, development, and manufacture of the
product. Given the specific medicinal product intended use and environment, this might result in
product-specific requirements and test methods that differ from what is outlined in this document.
This document is intended to be used for type testing (testing of the development result) of NIS-E. It is
not intended to be used for batch release testing.
This document introduces the notion of Type X NIS-E and Type Y NIS-E. Type X NIS-E is a device type
without any physical cabled connection to other devices. Type Y NIS-E has such connections. The
electrical requirements in this document for Type X NIS-E is a subset of the requirements for Type Y
NIS-E.

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.

Introduction
Needle-based injection systems including on-body delivery systems (OBDSs) containing electronics
with or without software are primarily intended to administer medicinal products to humans. This
document provides performance requirements regarding essential aspects of the design so that
variations of such injectors are not unnecessarily restricted.
For historical reasons (ISO 11608-1 was published before ISO 11608-4), the first edition of this document
was limited to pen-injectors with electromechanical drive systems. Pen-injectors only equipped with
electronics were covered in ISO 11608-1. Given the set of additional tests that need to be performed on
needle-based injection systems containing electronics (NIS-E) regardless of what the electronics are
used for, it was decided to have all types of NIS-Es covered by this document.
Materials to be used for construction are not specified, as their selection will depend on the design, the
intended use and the process of manufacture used by individual manufacturers.
There are other international and national standards and guidance publications and, in some countries,
national regulations that are applicable to medical devices and pharmaceuticals. This document serves
as a stand-alone document for NIS-E that specifies relevant aspects of the IEC 60601 series for this
particular device type. This document does not specify non-electrotechnical test methods, conditions,
or acceptance criteria for NISs when specified by other parts of ISO 11608.
Developers and manufacturers of NIS-Es are encouraged to investigate and determine whether there
are any other requirements relevant to the safety or marketability of their products. Their requirements
might supersede or complement those contained in this document.
Manufacturers are expected to follow a risk-based approach during the design, development and
manufacture of the product. Given the specific medicinal product intended use and environment, this
might result in product-specific requirements and test methods that differ from what is outlined in this
document.
Guidance on transition periods for implementing the requirements of this document is given in
ISO/TR 19244.

Part 4:
Needle-based injection systems containing electronics
1 Scope
This document specifies requirements and test methods for needle-based injection systems (NISs)
containing electronics with or without software.
The needle-based injection system containing electronics can be single use, reusable, and/or
rechargeable. It is intended to deliver medication to a patient by self-administration or by administration
by one other operator (e.g. caregiver or health care provider).
This document applies to electronic accessories which are intended to be physically connected to a NIS
or NIS-E during the NIS/NIS-E intended use.
NOTE This document includes relevant requirements derived from IEC 60601 series.
