ISO 10993

regulation

International standard that evaluates the biological safety of medical devices, including testing requirements for plastic materials and components used in medical applications.

In Simple Terms

ISO 10993 is the go-to standard for ensuring plastic materials are safe for medical use. It outlines specific tests to check if plastics cause harmful reactions when they contact the human body, from skin irritation to more serious biological responses.

Why It Matters

For plastic resin traders and processors serving medical markets, ISO 10993 compliance is mandatory. It determines which plastic grades can be used in medical devices, directly impacting material selection, pricing, and market access for healthcare applications.

Technical Details

The standard consists of multiple parts covering cytotoxicity, sensitization, irritation, systemic toxicity, genotoxicity, implantation, and degradation testing. Testing requirements depend on contact duration (limited ≤24h, prolonged ≤30 days, permanent >30 days) and contact type (surface, external communicating, implant). Materials must pass biological evaluation before medical device approval.

Real-World Examples

Medical-grade polycarbonate selection

A resin trader sources ISO 10993-tested polycarbonate grades specifically for dialysis equipment housings, ensuring biocompatibility for prolonged patient contact applications.

PVC compound certification

A medical tubing manufacturer requires PVC compounds with ISO 10993-5 cytotoxicity testing documentation before approving suppliers for IV bag and tubing production contracts.

Implantable device material validation

An orthopedic implant producer specifies PEEK resins with complete ISO 10993 biological evaluation including implantation studies for long-term biocompatibility in bone contact applications.
