Temperature aging testing
WebA selected temperature that exceeds the ambient temperature for the purpose of expediting the aging process of a product. Common aging temperatures are typically 50, 55, or 60C. Ambient Temperature (°C) This is the normal temperature range an item would experience on the shelf. Typical ambient temperatures range between 20 and 25C. WebAs aging progressed over time, DP was seen to decrease and at a faster rate as temperature was increased. Study of DP was especially beneficial because it began to change before significant change in strength properties could be detected.

WebOct 3, 2024 · Aging testing is a laboratory process that determines how quickly a material degrades, allowing for the prediction of its lifespan. It can mimic the harm done by UV rays, ozone, and temperature. Aging test chambers can quickly mimic the damage that would typically take months or years to occur outside. WebThermal ageing studies generally involve conditioning samples at either subambient or elevated temperatures in a temperature-controlled chamber, and then measuring residual properties after a few weeks or months.
WebDec 29, 2014 · Using a slightly adjusted acceleration factor of 2.3, aging is performed at a temperature of 55°C (131°F) to accelerate the process that supposedly will occur at 25°C (77°F). By cubing 2.3 we get 12.167, which leads to the tidy conclusion that a 30-day month at 55°C produces the same changes in material properties as one year at 25°C.
