Sterilization compatibility testing typically takes 4–8 weeks, depending on the number of test rounds, the combination of sterilization methods, and the completeness of the testing items.
1. Test Cycle Breakdown
|
Stage |
Required Time |
Description |
|
Sample Pretreatment |
1–2 days |
Drying treatment (120°C, 4–6 hours) to remove moisture and prevent hydrolysis interference during testing |
|
Cyclic Sterilization Execution |
2–4 weeks |
1–3 days between each sterilization round, completing 3–5 rounds of alternating sterilization (e.g., gamma → EO → steam) |
|
Performance Testing |
1–2 weeks |
After each round, tests are performed on appearance, mechanical strength, transmittance, chemical residues, etc. |
|
Data Analysis and Reporting |
3–5 days |
Summarizing data, assessing compliance, and issuing compliance conclusions |
Key Influencing Factors: If simulating long-term use (e.g., more than 10 cycles) is required, the total cycle may be extended to 10–12 weeks.
2. Accelerated Testing Solutions (Optional)
Shortened Cycle Methods: Using accelerated aging models (such as the Arrhenius equation) to predict long-term stability can compress testing to 2–3 weeks.
Applicable Scenarios: Suitable for mature materials with existing basic data, for rapid screening or process optimization.
Notes: Accelerated results need to be verified in conjunction with actual usage conditions and cannot completely replace real-world cyclic testing.
