Put you in an awkward position. Accelerated aging allows medical devices to enter the market before real-time data is available. Looking at the 1 Year RT (Real Time) row you can see that increasing from, °C sounds like a minor temperature fluctuation, but because temperature differences influence the power to which the, Look at the two calculations below.

Doing this will establish the items accurate expiration date. The material in your product with the lowest thermal transition should govern your accelerated aging temperature (, Increase aging temperature and you're increasing the power to which the. If Q10 = 2 and the accelerated aging condition is 55°C, or 30°C over an ambient temperature of 25°C, then the aging factor is 2^3 which equal 8. STERIS offers a range of accelerated aging chambers, which can accommodate both large pallets and single shipping units. Cause negative results from integrity testing after aging intervals passed. Westpak is proud to be an Employee Owned company. 3.2.8 real-time equivalent (RTE), n—amount of real-time aging to which given accelerated aging conditions are esti-mated to be equivalent. Increasing this factor will quickly decrease your aging time, but requires objective evidence the materials being tested follow the higher, Proving this is requires aging studies which take longer than using going with the, The safe bet is to always use 2, unless you have knowledge that is doesn't follow Arrhenius or has a higher. Alternatively, aging can be performed at multiple temperatures if data supporting the thermal thresholds of the relevant materials is not readily available or is not known. Having a proper understanding of how temperature can affect materials and products will ensure It is used to simulate real shelf-life aging and is conducted to validate shelf-life claims and document expiration dates. Check in on recent changes to some of Westpak's most commonly referenced protocols. Our animal science operations are accredited by AAALAC. Software-based Real-time operating systems (RTOS) enable medical device manufacturers to offer medical devices that drive the best medical outcomes but there is a growing demand to add IoT services to these devices that were once stand alone. This test enables manufacturers to get their product to market faster. The accelerated aging technique is based on the assumption that the chemical reactions involved in the deterioration of materials follow the Arrhenius reaction rate function. We are universally in favor of maintaining sterility and validating packaging to promote the efficacy of our clients’ products. Time spent sitting on the shelf could prevent lifesaving devices from helping patients in need or it could render the device obsolete before it reaches the market. Another option is to maintain at freezing temperatures for 24 hours in between high and low humidity.

Westpak maintains dedicated space for Real Time Aging in monitored rooms at ambient temperature and humidity. Learn ways we ensure everyone’s safety herex. DON’T subject packaging systems to conditions that are not representative of (or are more extreme) than what has been established as worst case forces of sterilization and storage by the MDM.

These principles sound so basic. When planning your device launch, it can be frustrating to think about waiting years to prove that a packaged product will still be safe for use down the road. Yet, so many issues that come into our lab began as nothing more than an oversight, a lower priority, or the reality that many teams operate without a regulatory consultant in house or on-call. The level of relative humidity (RH), while not specified by the standard, should be included at realistic levels. ANSI/AAMI/ISO 11607-1:2006 2. This function states that a 10°C temperature increase or decrease results in approximately two times increase or decrease in the rate of the aging process. Accelerated Aging simulates the effects of real time aging over shorter time frames and allows the manufacturer to predict the … 3.3 Symbols: Q10 = an aging factor for 10°C increase or decrease in Doing this will establish the items accurate expiration date. Studies can be performed to confirm the results of Accelerated Aging on test samples. Commonly referenced medical device standards and FDA guidance ... °C . Real-time aging is done at normal storage conditions. If you go in another direction, know the risks you are assuming and how you would rationalize your path if asked. There are two methods of testing that prove a packaging system’s ability to meet one of ISO 11607 requirements: By all means take advantage of the benefits of accelerated aging tests. Feel free to comment and provide feedback below. (714) 672-1090 Additional testing is performed after aging to access the packaging and/or product performance. If your device was distributed based on successful accelerated aging validation results, and then real time aging validation testing shows contradicting evidence that the packaging could not maintain sterility as required by ISO 11607. Values above 60°C are not recommended. Medical device manufacturers wishing to gather data on the shelf life of their products may subject their devices to long-term stability studies or accelerated aging studies.

Westpak offers white papers as a useful time-saving reference. The test is conducted by placing the test item on a shelf and allowing it to be exposed to typical storage conditions. This includes: Processing (molding, extruding, thermoforming, etc) could have an effect on thermal transitions. Accelerated aging is an area that each person involved in the product development process should have at least a high level understanding of because it is often on the critical path for new products and design changes.

ISO 11607 Westpak maintains dedicated space for Real Time Aging in monitored rooms at ambient temperature and humidity. In parallel with accelerated aging, the manufacturer must also conduct a real-time study in order to validate the data generated during the accelerated aging process. under normal storage conditions. Real Time Aging This testing is conducted at ambient conditions in actual real time in order to analyze the conditions of packages and/or products and the effects that time has on them.

Accelerated aging is probably not everyone's favorite med device topic, but it's one I enjoy. Over 47 days (~1.6 months), which would have a significant impact on labeling. Accelerated aging is also known as shelf life, stability, or expiry dating testing. ASTM F1980-07 (2011) This function is expressed as a Q10 factor – i.e. Do you know what can happen if steps are skipped or overlooked? Therefore, 45.6 days at 55°C is equivalent to one year at an ambient temperature of 25°C. You may get early results that your packaging performs well—or early warning of a problem that can be fixed now, before launch. Home / Medical Package Testing Services / Real Time Aging Real-Time Aging programs provide the best data to determine shelf life and the effects of aging on materials. If you’re facing an issue or would like to connect with a regulatory expert, check out the PCL ISO 11607 Audit Microprogram.
3.2.9 zero time (t0), n—the beginning of an aging study. Simulation is achieved by varying temperature and humidity levels and thus exposing the packaged device to conditions it is expected to survive during its shelf life. Ensure material thermal transitions are not reached. Create difficulty in proving to governing bodies that your packaging system has been properly validated through stability testing. CORPORATE HEADQUARTERS Check in on the Westpak Leadership team and see what we're up to.
