Proving 3 Years on the Shelf in Months

A device that’s perfect on the day it’s made still has to be perfect three years later, on the day it’s actually used.

Accelerated Aging and Shelf-Life Testing is the category of material testing for medical devices that answers a question no other study can: will this device, and its packaging, still perform the way it’s supposed to after months or years sitting in a warehouse, a hospital store room, or a field kit? Our Accelerated Aging and Shelf-Life Testing service at the Oragadam laboratory exists to answer that question with data, not assumption — using elevated-temperature and elevated-humidity chambers to compress years of real-world aging into a matter of weeks.

Accelerated aging testing is the core method here. Samples are stored in controlled chambers at elevated temperature and humidity, following recognized time-temperature relationships to simulate a target shelf-life — commonly one, two, or three years — in a fraction of the real time. It’s the fastest way to get a defensible shelf-life claim onto your labeling, and it’s why this is usually the first study a manufacturer runs when establishing a new shelf-life for a device or its packaging.

Accelerated data alone isn’t the whole picture, though, which is why real-time aging testing runs alongside it — storing identical samples under actual ambient conditions for the full claimed shelf-life to confirm the accelerated model held true. Once samples have gone through either aging pathway, two more evaluations complete the picture. The next study checks whether the material itself — its strength, flexibility, color, or chemical stability — has held up after aging, since a package or component that’s aged into brittleness or discoloration has effectively failed even if it still looks intact. Product-performance verification after aging testing goes one step further, confirming the finished device still performs its intended function — not just that the material survived, but that the device built from it still works exactly as designed.

Together, these four studies build the shelf-life evidence a regulatory submission requires, and they connect directly to the rest of your medical device testing program — a device that’s already been through our biocompatibility work under the ISO 10993 series needs its aging data to confirm that biological safety profile still holds at the end of its claimed shelf life, not just on the day it left the factory floor. Manufacturers who treat aging and shelf-life data as an afterthought often find themselves reworking a submission late, when a simpler upfront study would have closed the gap the first time.
