Overview
SIST EN ISO 10993-12:2021/A1:2025 is an amendment to the established European Standard for the biological evaluation of medical devices, specifically focusing on sample preparation and reference materials. Published by the European Committee for Standardization (CEN), this amendment aligns with the requirements of Regulation (EU) 2017/745 for medical devices. The updated standard clarifies terminology, references, and procedures to ensure consistency and compliance within biological testing frameworks across Europe.
This standard is integral for manufacturers, testing laboratories, and regulatory stakeholders engaged in risk management and biocompatibility evaluation of medical devices. It supports the demonstration of conformity with key safety and performance requirements through standardized sample preparation and referencing of materials during testing.
Key Topics
-
Sample Preparation for Biological Evaluation
EN ISO 10993-12 provides detailed protocols for preparing samples of medical devices before testing to ensure reproducibility and reliability. The amendment introduces specific guidance for devices containing absorbent materials, impacting extraction volumes and ratios.
-
Reference Materials
The standard defines requirements and considerations for selecting and using reference materials during biological evaluations, essential for comparability across laboratories.
-
Relation to Risk Management Standards
References and aligns with key ISO standards, such as ISO 14971 (risk management) and ISO 10993 series, ensuring that biological evaluations are integrated with comprehensive risk management practices.
-
Harmonization with EU Regulation
SIST EN ISO 10993-12:2021/A1:2025 serves as a voluntary means to demonstrate conformity with the General Safety and Performance Requirements of Regulation (EU) 2017/745, supporting regulatory submissions and CE marking for medical devices.
-
Clarified Testing Definitions and References
The amendment updates references to ISO 10993-1, ISO 10993-18, and ISO/TS 10993-19 and ensures the terminology aligns with current regulatory frameworks.
Applications
