ASTM-F Standard Guide for Accelerated Aging of Sterile Barrier Systems for Medical Devices The introduction of new or modified products to the marketplace requires the assurance that they can be stored for an extended period one year, two years, etc.
Conservative accelerated aging factors AAFs must be used if little is known about the sterile barrier system material being evaluated. To ensure that accelerated aging studies do truly represent real time effects, real time aging studies must be conducted in parallel to accelerated studies.
ASTM F – 07 standard guide for accelerated aging of sterile barrier systems for medical devices 0. Accelerated Aging calculation is based on Arrhenius’ equation which simply states that a 10C increase in temperature doubles the rate of chemical reaction.
New rules for flare stack combustion from the US Environmental F1980-0 Agency EPA set to take effect in early include additional monitoring and analysis requirements that make it necessary for refinery operators to quickly and accurately determine the heat values of flare stack gases.
Stability testing shall demonstrate that the sterile barrier system maintains integrity over time. Accelerated Aging is an artificial procedure for establishing the lifespan or shelf life of a product in an expedited manner. On September 29,the U.
Determining the heating values of vent gas is important because sufficient combustible material must be continuously present to achieve high combustion efficiencies. Four variables are used in calculating the accelerated aging test duration. A product can be released to market based upon successful Accelerated Aging test results that simulates the period claimed for product expiration date 1 year, 2 years, etc. Evaluate the package performance after accelerated aging relative to the initial package requirements.
The sterile barrier system material and device interaction compatibility that may be required for new product development or the resulting evaluation is not addressed in this guide. The sterile barrier system shall maintain sterility to the point of use or until the expiry date. Accelerated aging studies can provide an alternative means. Stability testing using accelerated aging protocols shall be regarded as sufficient evidence for claimed expiry date until data from real time aging studies are available.
Try out our Accelerated Aging Calculator! Real time studies must be carried out to the claimed shelf life of the product and be performed to their completion. The resulting creation of an expiration date or shelf life is based on the use of a conservative estimate of the aging factor for example, Q10 and is tentative until the results of real time aging studies are completed on the sterile barrier system.
In parallel, age samples at real-life aging conditions TRT.
Accelerated Aging – Sterile Barrier Association
ASTM F procedure for accelerated aging is comprised of the following: Data obtained from the study is based on conditions that simulate the effects of aging on the f1980-007.
A calculator is provided below to easily explore difference test scenarios.
The introduction of new or modified products to the marketplace requires the assurance that they can be stored for an extended period one year, two years, etc. The primary accelerated aging standards pertaining to sterile barrier systems for medical devices are:. The new Thermo Scientific SOLA iQ online sulfur analyzer helps technicians, engineers and managers in the oil and gas industry measure total sulfur content of liquid or gas phase samples without requiring time-consuming lab analysis.
Detailed information is provided in the data protection policy.
ASTM-F – Accelerated Aging – Medical Package Testing
It involves the determination of oxidizability, also known as oxygen O2 demand, by potassium permanganate ISO method When conducting accelerated aging programs for establishing expiry dating claims, it must be recognized that the data obtained from the study is based on conditions that simulate the effects of aging on the materials.
Evaluate package, or package performance, or both, after real time aging relative to the initial package requirements.
Note 1—Determining AAFs are beyond the scope of this guide. What is permanganate index? Developed in close collaboration with Dr. Accelerated Aging data is recognized by regulatory bodies as a conservative v1980-07 of the shelf life, but is only accepted until those tests can be repeated on “real time” aged samples.
However, due to market conditions in which products become obsolete in a short time, and the need to get new products to market in the shortest possible asstm, real time aging studies do not meet this objective.
Shimadzu Corporation, a leading manufacturer of analytical and medical instruments, announces the release of a trace moisture analysis system utilizing a gas chromatography method. More aggressive AAFs may be used with documented evidence to show a correlation between real time and accelerated aging.
