Test Parameters

Test temperature must be higher than the ambient / reference temperature for the acceleration model to be valid.
ASTM F1980-21 (Section 7.2.3.2) recommends keeping accelerated aging temperatures at or below 60 °C. Above this threshold, polymeric materials may show non-linear behavior not representative of real-time aging.

Represents real-world storage conditions.

ASTM F1980-21 default. A Q10 of 2.2–2.5 may be used if the material system is sufficiently characterized in literature and documented failure modes are comparable. Values above 2.5 require explicit justification (ASTM F1980-21, Section 7.3.1).

Pull Schedule

Relative Humidity

Per ASTM F1980-21 (Appendix X3), define the target RH and control it where the material system is moisture-sensitive.

Real-Time Aging (Concurrent)

ASTM F1980-21 (Sections 1.2 & 4.3): real-time aging runs in parallel and confirms shelf life. ISO 11607-1:2019 (Section 8.3.4): accelerated aging shall begin within three months of real-time aging.

⚠️ Accelerated aging should begin within 3 months of real-time aging per ISO 11607-1:2019, Section 8.3.4. If exceeded, document a rationale in the protocol.

How to Use the Accelerated Aging Calculator

Calculate accelerated aging time for your sterile barrier system in seconds. Enter your test temperature, ambient reference, Q10 factor and target shelf life, and the calculator returns your acceleration factor, accelerated aging duration (AAT), test end date and a complete pull schedule per ASTM F1980 and ISO 11607. Every calculation runs locally in your browser. Nothing is uploaded, nothing is stored. When the numbers are right, copy the ready-made protocol section straight into your validation document.

What the Accelerated Aging Calculator Does for You

You set four inputs and get a defensible study design back. Test temperature, ambient storage temperature, Q10 factor and desired shelf life drive the acceleration factor, the elevated-temperature test duration and the pull dates for each sample point. The protocol export gives you a clean, self-contained section to paste into Word, with the Q10 justification clearly flagged as the one parameter you must defend with your own material data.

This replaces the spreadsheet most teams still copy from colleague to colleague, version after version, with no traceability. You get the same Arrhenius-based math, the conservative rounding auditors expect, and output you can drop into a protocol without reformatting.

Frequently Asked Questions

How does the Accelerated Aging Calculator work?

The calculator applies the Q10 simplification of the Arrhenius reaction rate model described in ASTM F1980. The fundamental assumption is that the aging mechanisms degrading sterile barrier system materials follow Arrhenius kinetics, with the reaction rate doubling or more for every 10 °C increase in temperature. From your test temperature, ambient reference temperature and Q10 factor it derives the accelerated aging factor (AAF), then divides your desired shelf life by that factor to give the accelerated aging time (AAT). It also builds a pull schedule with a date for each sample point. The formula is AAF = Q10^((T_test − T_ambient) / 10), and AAT = desired shelf life / AAF.

What temperature should I enter in the Accelerated Aging Calculator?

ASTM F1980 does not prescribe a specific accelerated aging temperature, but recommends a range of roughly 40 °C to 60 °C for most medical device packaging materials. 55 °C is the most common choice in practice. A temperature in excess of 60 °C should not be used, because elevated temperatures can affect polymeric materials in ways that would never occur during real-time or room-temperature storage. For the ambient reference, use a value that reflects actual storage and in-use conditions, generally between 20 °C and 25 °C, with 25 °C being the more conservative choice. 

What Q10 value does the Accelerated Aging Calculator use?

ASTM F1980 recommends a default Q10 of 2.0, meaning the reaction rate is assumed to double for each 10 °C rise in temperature. Higher Q10 values, in the range of about 2.5 to 3.5, are used for some materials and reactions but require supporting validation data. The Q10 of 2.0 is widely used because it is conservative for most packaging polymers. Whichever value you select, document the justification, since this is the parameter auditors challenge most often.

Can the Accelerated Aging Calculator replace real-time aging?

No. Accelerated aging data may be regarded as sufficient evidence for expiration date claims only until data from real-time aging studies become available. Real-time aging is the requirement of ANSI/AAMI/ISO 11607-1:2019, and accelerated aging results stay tentative until the real-time study on the sterile barrier system is complete. Run both studies in parallel, starting them together.

Is the Accelerated Aging Calculator suitable for regulatory submissions?

The calculations follow the methodology of ASTM F1980-21, the FDA-recognised consensus standard for accelerated aging of sterile barrier systems and medical devices, and align with ISO 11607-1:2019. ISO 11607-1 requires shelf-life studies to demonstrate that the sterile barrier system maintains integrity through the claimed expiration date, and accepts aging protocols as sufficient evidence for claimed expiry dates until real-time data are available. The output supports your validation protocol and submission, but you remain responsible for confirming every parameter against your applicable test plan and material data.

Does the Accelerated Aging Calculator account for humidity?

No, and that is intentional. The Q10 temperature model drives the duration calculation. The 2021 revision of ASTM F1980 added emphasis on considering ambient relative humidity during accelerated aging, because the properties of some materials depend on absorbed moisture. If your materials are moisture-sensitive, the standard recommends conducting the study at around 50 % relative humidity, while you still choose your own temperature. Decide on humidity control as part of your test plan, separately from the time calculation.
