Accelerated aging (AA) is testing that uses aggravated conditions of heat, oxygen, sunlight, vibration, chemicals, etc. to speed up the normal aging processes of items. It is used to help determine the long-term effects of expected levels of stress within a shorter time, usually in a laboratory by controlled standard test methods.
AA is used to estimate the useful lifespan of a product or its shelf life when actual lifespan data is unavailable. The ability of product designers to accurately predict changes in polymer properties is of critical importance to the medical device, consumer, and industrial markets.
Join this Webinar to better understand and start taking advantage of accepted Accelerated Aging Techniques. Understand General Aging Theory – The Simplified Protocol for Accelerated Aging (10 Degree Rule) and Iterative Test Designs.
In order to design a test plan that accurately models the time correlated degradation of polymers, it is necessary to have an in-depth knowledge of materials composition and structure, end product use and mis-use, assembly and sterilization process effects. Basic polymer chemistry will be reviewed as well as the changes in polymer characteristics that can be anticipated and designed for. Learn how to plan for post-production and lifetime functionality.
