CE, US FDA & ISO 13485: What Each Medical Certification Really Means
A plain-language guide to the standards that matter when sourcing healthcare products — and how to check them.
In short
A technical engineering comparison of Ethylene Oxide (EO) and Gamma radiation sterilization methods for exported medical disposables.
Technical Comparison: EO Gas vs. Gamma Radiation
| Operational Factor | Ethylene Oxide (EO) Gas Sterilization | Gamma (Cobalt-60) Radiation Sterilization |
|---|---|---|
| Governing Standard | ISO 11135:2014 | ISO 11137-1 / -2 / -3:2012 |
| Material Compatibility | Broad polymer compatibility; safe for delicate plastics | Can induce cross-linking, embrittlement, or yellowing in certain plastics |
| Packaging Constraints | Demands a gas-permeable barrier (Tyvek or medical paper) | Works through completely impermeable foils, poly-pouches, and cartons |
| Post-Process Quarantine | Demands 7 to 14 days of aeration to dissipate gas residuals | Zero quarantine; instant dosimetric batch release |
| Residual Testing | Batch testing for residual EO and Ethylene Chlorohydrin (ECH) | Zero chemical residues; no chemical extraction testing needed |
| Common Applications | IV cannulas, surgical drapes, tubing sets, catheters | Surgical blades, sutures, container-sealed fluids, plastic labware |
Sterilization choice is governed by material physics. Applying gamma radiation to certain polypropylene grades causes polymer degradation and yellowing, while EO demands breathable, permeable packaging.

Frequently asked questions
What does Sterility Assurance Level (SAL) 10⁻⁶ signify?
An SAL of 10⁻⁶ indicates a probabilistic standard where there is no more than a one-in-a-million chance of finding a viable microorganism on a sterilized medical device, the global benchmark for invasive surgical consumables.
Why cannot all medical devices be sterilized with Gamma radiation?
Certain polymers—such as PTFE, standard polypropylene, and natural rubber latex—undergo radiation degradation, losing tensile strength, developing discoloration, or emitting odors when exposed to high-energy gamma rays.
