Introduction
This document is applicable to needle-based injection systems (NIS) with automated functions (NIS-
AUTO) primarily intended to administer medicinal products to humans. Because of the anticipated
variation in the designs of NIS-AUTOs, it tends to specify the results of the design effort instead of the
physical and construction requirements used as the basis for NIS-AUTO design, so that innovation in
achieving the intended purposes is not unnecessarily restricted. As such, this document intends to
address basic elements regarding the safety and performance of NIS-AUTOs.
Despite certain advantages for intentional interchangeability for containers designed for different auto-
injection systems, as well as the potential risks of inadvertent interchangeability, this document avoids
setting forth design specifications for the uniform size, shape and interface of such containers. It is left
for future initiatives to build upon the specifications in this document.
ISO 11608-1 is the umbrella document of the ISO 11608 series. All other parts, including this document,
are to be used in conjunction with ISO 11608-1.
Guidance on transition periods for implementing the requirements of this document is given in
ISO/TR 19244.

— IEC Electropedia: available at http:// www .electropedia .org/
— ISO Online browsing platform: available at http:// www .iso .org/ obp
3.1
actuation
action which initiates a NIS-AUTO function (e.g. needle insertion (3.14)), carried out by the NIS-AUTO
user (or by another automated function (3.2))
EXAMPLE Pressing the NIS-AUTO (3.9) against the injection site.
3.2
automated function
function which does not require user interaction after actuation (3.1)
Note 1 to entry: A dose counter is considered an automated function if it changes its state without any user
interaction.
3.3
disabling
function that changes the state of the NIS-AUTO (3.9) such that it is not able to be refilled, reloaded,
reset, or reactivated for dose delivery, which will allow the NIS-AUTO (3.9) to perform any subsequent
injections (including single-dose and the last dose of multi-dose systems)
3.4
dose setting (and memory)
function which sets the dose to be delivered (dose setting) and/or displays the previously set dose
(memory)
3.5
injection of medicinal product
function which delivers the dose
3.6
injection time
time from actuation (3.1) to completion of the injection of medicinal product (3.5) as described in the IFU
3.7
intended injection depth
range of distance from the skin surface to the point at which the medicinal product is intended to be
delivered
Note 1 to entry: See Figures in Annex C.

3.9
needle-based injection system with automated function
NIS-AUTO
injection system that delivers a medicinal product through a needle wherein one or a series of functions
are initiated by an action of the user and controlled automatically by the injection system
Note 1 to entry: Accessories that perform automatic functions in combination with manual injection NIS-AUTOs
are regarded as NIS-AUTO.
3.10
needle cover
cover provided over a needle in order to protect the needle from damage and users from injury
prior to use
Note 1 to entry: A needle cover alone is not a sharps injury protection feature unless it complies with ISO 23908.
3.11
injection depth control
function which controls the needle extension (3.12) such that the medicinal product is delivered at the
intended injection depth (3.7)
3.12
needle extension
axial distance from the patient end of the needle tip to the nearest part of the NIS-AUTO body (defining
the point of contact with the patient adjacent to the injection site)
3.13
needle hiding
function which intentionally obscures the needle from the user's sight either before, during or after the
injection cycle
Note 1 to entry: The needle hiding function only has a visual requirement. It is not subject to any physical or
dimensional requirements intended to restrict access to the needle. It does not imply any increased level of safety
from needle stick injuries.
3.14
needle insertion
function which inserts the needle into the injection site to the intended injection depth (3.7) prior to the
injection of the medicinal product
3.15
needle preparation
function which prepares the needle for use (e.g. needle attachment, removal of needle cover (3.10), etc.)
Note 1 to entry: The needle preparation function may be a feature of the design and not a mechanical action.
For example, a NIS cap may contain features that interact with the needle cover (3.10) and when the NIS cap is
removed, the needle cover (3.10) is automatically removed.
3.16
needle removal
function which disconnects the needle from the NIS-AUTO fluid path
3.17
needle retraction
function which removes the needle from the target tissue to a predefined position inside the NIS-
AUTO (3.9)

3.18
needle shielding
function which covers the needle before and/or after the injection cycle to reduce the likelihood of
direct contact with the needle
Note 1 to entry: Needle shielding alone is not a sharps injury protection feature unless it complies with ISO 23908.
3.19
priming
function that makes the dosing mechanism of the NIS-AUTO (3.9) ready for dose administration (e.g.
removing the air from the fluid path)
Note 1 to entry: Needle preparation (3.15) and fluid path connection should be considered separately.
3.20
recording
function which records information (e.g. dose counter)
Note 1 to entry: A NIS-AUTO (3.19) may include several different, possibly related, recording functions, which
record different pieces of information related to the dose administered.
4 Requirements
4.1 General requirements
a) Any automated function considered a primary function shall be verified in accordance with
ISO 11608-1.
b) Where the completion of an automated function is intended to be communicated to the user, it shall
be apparent by visual means; and either tactile or audible means (i.e. visual and tactile, visual and
audible) unless otherwise specified in this document.
c) Users shall be able to clearly distinguish between a NIS-AUTO that is unused, in use, used or
disabled or requiring another "setup" step before it can be used again. For automated functions
that change the state of the NIS-AUTO, a visual indication of the NIS-AUTO state shall be provided
(e.g. ready for use in use, disabled or other states relevant for the particular NIS-AUTO).
d) Where the design of a NIS-AUTO allows manual operations to be performed in a sequence other
than that specified in the instructions for use, the risk assessment shall address the risks of out-of-
sequence operation.
e) Actuation of each automated function shall meet the following requirements:
1) Actuation of injection: A minimum of two manual actions shall be required in order to initiate
injection, e.g. from locked to unlocked state/ready for injection, then press to actuate. A
multi-dose/use injection system with automated functions, once actuated, shall not allow an
additional actuation without a separate and distinct action prior to a subsequent actuation.
2) Actuation shall be tested in accordance with 5.3.
f) Automated functions shall not interfere with the primary functions of the NIS-AUTO.
g) For each automated function included within the NIS-AUTO design, the manufacturer shall apply
the applicable requirements in this paragraph and perform testing in accordance with Clause 5.
Where the design does not include the automated function, or does not automate the function,
the relevant requirements of Clause 4 do not apply, and testing in accordance with the sections of
Clause 5 is not needed. Refer to Table 1 for a matrix of the specific requirements and test methods
for each automated function.

4.4 Needle hiding
If automated needle hiding is applicable before, during or after injection, the needle shall not be visible
when the device is placed against the injection site, when tested in accordance with 5.6.
NOTE Post-injection needle hiding is not considered to be needle shielding. The needle hiding function only
has a visual requirement. It is not subject to any physical or dimensional requirements intended to restrict access
to the needle. It does not imply any increased level of safety from needle stick injuries.
4.5 Priming
Dose accuracy testing shall be performed once priming is complete. The NIS-AUTO shall indicate to the
user that the automated priming has been completed by at least visual means.
Priming shall be tested in accordance with 5.7.
4.6 Dose setting
Following automated dose setting the NIS-AUTO shall provide an indication that the dose has been set
by at least visual means.
It shall be verified that the input(s) to the automatic dose setting function result in the intended set dose.
4.7 Needle insertion
The needle shall not be damaged by the automated feature, when tested in accordance with 5.5.
