Calculation of accelerated aging according to ASTM F 1980 Here you are able to calculate how long they have to perform at elevated temperature a storage tests to reflect the reality as closely as possible in the laboratory . However, a stress at the use condition is usually random, so how can we calculate the equivalent acceleration factor for a random stress? Accelerated aging factor: To be specified. www.evaluationengineering.com is using a security service for protection against online attacks. This is logarithmic or accelerated aging. ate – verb \ -ləˌrāt\ : to move faster : to gain speed – : to cause (something) to happen sooner or more quickly 2. 4.5 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. If the use stress is a constant value, this is easy to calculate. – the period from birth to death – the period of duration, usefulness, or popularity of something
