ISO 10993-11 Cytotoxicity Testing Post Chemical ExposureISO 10993-11 Cytotoxicity Testing Post Chemical Exposure Laboratory Testing Services
ISO 10993-11:2015 is a widely recognized standard that specifies the requirements for cytotoxicity testing of medical devices and materials after chemical exposure. This standard is part of the ISO 10993 series, which provides guidance on biological evaluation of medical devices.
Legal and Regulatory Framework
The ISO 10993-11 standard is designed to meet the regulatory requirements of various countries and regions, including the European Union (EU), the United States (US), Japan, and others. The standard ensures that medical devices and materials are safe for human use by assessing their cytotoxic potential.
International and National Standards
The ISO 10993-11 standard is based on several other standards, including:
These standards provide a framework for the evaluation of medical devices and materials, including cytotoxicity testing.
Standard Development Organizations
The International Organization for Standardization (ISO) is responsible for developing and maintaining international standards. The ISO 10993 series is maintained by Technical Committee 194, which brings together experts from various countries to ensure that the standards are up-to-date and relevant.
How Standards Evolve and Get Updated
Standards evolve over time as new technologies emerge and regulatory requirements change. The ISO 10993-11 standard has undergone several revisions since its initial publication in 1993. Each revision incorporates new scientific evidence, advances in technology, and changes in regulatory requirements.
