Overview:

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.

Why should you Attend: Accurate prediction of product shelf-life performance is critical to your success. "Do it right the first time", choose the most functional and resistant materials for your product instead of going through the post launch cycle of panic driven product revisions. Also learn the basis for choosing the optimum accelerated test design based on materials, product design, processing, and functional product requirements. Learn how to "think like a molecule" and plan and design around "aging" induced changes in materials qualities (brittleness, color, and odor) that cut short your product's long term functionality. The understanding of a product's long term safety and efficacy is a must in today's litigious world.

Learn how to:

  • Understand the design and use of accelerated aging programs to shorten development time
  • Identify the materials that perform best in "stressful" environments
  • Effects of processing (molding, assembly)
