Accelerated Aging

Accelerated Aging Testing Services

Accelerated aging is the expedited aging process of a product by subjecting it to aggravated operational and environmental conditions like temperature, pressure, humidity, light, and vibration. The goal of the study is to achieve long service life exposure in a shorter time frame to understand possible failure modes. It is routinely used in the medical device industry to estimate the lifespan or shelf life of products. It is also used in determining the aging response in structural materials and metal alloys, shelf life in the food industry, degradation chemistry in polymers, assessment of sealing, and faults in packaging. Furthermore, mechanical testing, physical and chemical analysis, potency, and other metrology testing are also done on the sample or device to quantify the aging process to generate data for prediction models.

The product undergoes physical or chemical testing by exposing it to long-term average stress levels, very high stress levels used to hasten the effects of aging naturally, or stress levels used to deliberately induce failure (for further analysis). Mechanical components are subjected to far higher speeds of operation than they would experience during regular use. It is common practice to maintain polymers at high temperatures in order to hasten chemical deterioration. The field of library and archival preservation also employs accelerated ageing. In this situation, a substance—typically paper—is put through harsh measures in an effort to hasten the ageing process.

There is no solitary approved set of circumstances in which these tests ought to be carried out. The environmental chambers and methodologies used for accelerated aging vary widely depending on the product being tested. There are industry standards in place, including AANSI ASTM, ISO, etc. Custom conditions and protocols are also developed for unique test article requirements. Some researchers have started comparing materials that have experienced accelerated aging to materials that have undergone natural ageing in an effort to improve the quality of accelerated aging studies.
