Overview
ISO 11608-3:2022/Amd 1:2026 is an international standard amendment focused on needle-based injection systems (NIS) for medical use, specifically addressing requirements and test methods for containers and integrated fluid paths. Developed by ISO Technical Committee 84 in collaboration with CEN, this amendment aligns with current regulatory requirements and harmonizes practices for managing particulate contamination in needle-based injection system components. The standard provides updated guidelines for testing and verifying that containers and integrated fluid paths in NIS maintain safety, quality, and compatibility with medicinal products.
Key Topics
-
Particulate Matter Requirements
The amendment revises requirements for both sub-visible and visible particulates that may be present in the reservoir and fluid path of NIS:
- Establishes specific limits for particles ≥10 µm and ≥25 µm, referencing updated methodologies aligned with pharmaceutical standards.
- Provides recommendations for risk-based assessment and control strategies throughout the design and manufacturing lifecycle.
- Stresses the importance of minimizing particulates to avoid negative impact on patient safety and device performance.
-
Harmonization with Pharmacopeia and Industry Standards
The standard references key pharmacopoeial methods and documents (e.g., USP, PhEur, JP) for particulate testing, and aligns with related ISO standards such as ISO 11040-4 and ISO 8536-4.
-
Patient Safety and Risk Management
Annex G introduces a risk-based approach for setting particulate limits, addressing factors such as patient population, route of administration, frequency of use, and the physical characteristics of particulates. Design verification processes must demonstrate that safety and functional requirements are met.
-
Control Strategies and Supplier Management
Emphasizes environmental controls, supplier qualification, and ongoing lot testing to monitor and control particulate contamination. Requires reevaluation after design or process changes.
Applications
ISO 11608-3:2022/Amd 1:2026 is applicable to organizations involved in the design, development, manufacturing, and quality assurance of needle-based injection systems for:
- Drug delivery devices, including prefilled syringes, pen injectors, and auto-injectors
- Integrated fluid pathways within injection systems
- Medical device components that contact medicinal products
By implementing the requirements, manufacturers can:
- Demonstrate compliance with international best practices for patient safety and product quality
- Facilitate market access in regulated environments by aligning with current pharmaceutical and medical device standards
- Reduce the risk of adverse events associated with particulate contamination
- Streamline supplier management and component qualification processes
Related Standards
To support comprehensive compliance in the design and delivery of needle-based injection systems, ISO 11608-3:2022/Amd 1:2026 references and aligns with several key standards, including:
- ISO 10555-1:2023 - Intravascular catheters - General requirements
- ISO 11040-4:2024 - Prefillable syringe barrels - Glass
- ISO 11040-6 - Prefillable syringe barrels - Plastic
- ISO 8536-4 - Infusion equipment for medical use
- USP 790/USP 1790 - Visual inspection of injections and visible particulates in injections
- ICH M7(R2)/Q3D(R1) - Risk assessment of impurities in pharmaceuticals
These references ensure that the control and assessment of particulate matter in needle-based systems are consistent with global pharmaceutical and device industry requirements, supporting both safety and performance.
