05 / Important Considerations
The calculation is only as appropriate as its assumptions.
Q10
The selected Q10 must be appropriate for the product and material system. Q10 = 2 is a commonly used conservative assumption, not a universal value.
Temperature
The accelerated aging temperature must be appropriate for the materials, packaging, and product being evaluated.
Real-Time Aging
Real-time aging remains required to confirm accelerated-aging results.
Protocol
This calculator assists with duration estimation; it does not establish a validated aging protocol, shelf-life claim, or regulatory approval.
Material Behavior
The calculation does not evaluate physical transitions, degradation mechanisms, or material interactions.
Humidity + Testing
Humidity may be addressed in a protocol where appropriate, but it is not modeled as an acceleration factor here. The tool does not determine test methods or acceptance criteria.
