Abstract
When preparing a computer program involving the use of insulation life expectancy data, it is necessary to know the equation for the life expectancy, or loss-of-life vs. temperature relationship. This information is often presented in chart form for which, in many cases, the equation is not given. To those who work closely with the accepted chemical reaction rate theory (Arrhenius relationship) for thermal aging, there is little problem in determining the constants A and B in life (L) vs. temperature (T) charts based on the equation ln L = B/T + A.Keywords
