Down time is measured at 85°C/85%, 85°C/70%, 75°C/75%, 65°C/85%, and the estimated average life is the point where the approximated curve coincides with 25°C/50%.
Down time: time when 280 PI errors are reached
Approximate equation: ln(t)=ln(A)+(Es/k)×T-1+B×R

Life Expectancy and Average Down Time of Optical Disc
The ISO/IEC10995 defines the life expectancy of an optical disc as the point of 5% failure rate (95% uptime rate).
Disc products with a life expectancy of 30 years or longer are certified by ADTC.
(1) Calculation of “estimated life” based on 25°C and 50% RH (simplified into a 2-dimensional graph)
Accelerated aging time under the different temperature/humidity environments are processed statistically to calculate the distribution of the “estimated life” based on 25°C and 50% RH.
