Overview
EN ISO 11608-1:2022/prA1:2025 (ISO 11608-1:2022/DAmd1:2025) is an amendment to the international standard for needle-based injection systems for medical use. It clarifies terminology and testing sequences used to verify safety and performance of needle-based injection systems (NIS), without introducing new technical requirements. The amendment focuses on consistent use of terms such as normal/anticipated conditions, in-use conditions, conditioning/preconditioning, and refines the sequence for visual inspection and primary-function assessments.
Key topics and technical requirements
- Primary functions identification
- Primary functions must be derived from design specifications and include, at minimum, the dose delivery function as governed by dose accuracy requirements.
- Test apparatus performance (Gauge R&R)
- Repeatability and reproducibility (Gauge R&R) for test equipment shall be ≤ 20% of the specification range for non‑destructive measurements; for destructive tests Gauge R&R ≤ 30%.
- Gauge R&R should cover approximately ±2 standard deviations (~95% of variation).
- Testing conditions and sequence
- Tests are to be performed at standard atmosphere unless otherwise specified.
- Visual inspection (Clause 11) and primary‑function assessment (Clause 7 / 5.7.2) are emphasised: inspection is recommended after stressed/challenge exposure and/or before primary‑function testing at normal/anticipated conditions.
- Conditioning: assembled NIS with filled container (needle removed if removable) must be conditioned for at least 4 h in specified atmospheres (Table 4).
- Life‑cycle and functional stability
- Life‑cycle testing verifies primary functions after delivering 1.5× the maximum expected actuations to provide a safety margin above the expected duty cycle.
- Functional stability covers shelf‑life (manufacture to first use) and in‑use life (actual usage to disposal); intent is for NIS to meet primary functions through labelled shelf and in‑use life.
- Test matrix and scope
- Clause 9 / Table 3 provides the test case matrix linking system designations to required tests, including stressed/challenge and normal/anticipated conditions.
Practical applications
- Establishes how manufacturers should verify dose accuracy, durability, and functional stability of pens, autoinjectors and similar NIS during design verification, production validation and post‑market assessment.
- Guides test laboratories on acceptable measurement systems, calibration and Gauge R&R criteria for NIS testing.
- Informs risk assessments and labeling decisions related to shelf life and in‑use life.
Who should use this standard
- Medical device manufacturers (R&D, design verification, quality)
- Test and calibration laboratories
- Regulatory compliance and submissions teams
- Clinical engineers, product safety officers, notified bodies
Related standards
- Other parts of the ISO 11608 series (see ISO website for full list) cover additional aspects of needle‑based injection systems such as requirements for specific device types and accessories.
Keywords: needle-based injection systems, ISO 11608-1 amendment, dose accuracy, life-cycle testing, Gauge R&R, primary functions, in-use life, standard atmosphere, medical injection pens.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 84, Devices for administration of medicinal
products and catheters.
This amendment addresses editorial inconsistencies with regards to terminology introduced in the
last revision, e.g. use of "anticipated/normal conditions" vs. "in-use conditions" and interchangeable and
inconsistent use of "conditioning" and "preconditioning".
In addition, it tries to improve subclause 10.2 with regards to the sequence of visual inspection and
assessment of primary functions.
It does not introduce new requirements, and it does not change existing requirements.
A list of all parts in the ISO 11608 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.
