The D price or decimal aid time is deﬁned because the time at a given temperature for the surviving inhabitants to be diminished by means of 1 log cycle, i. e. 90%. The temperature at which a D price applies is indicated by means of a subscript, e. g. D65. A D worth might be got from a plot of log10 survivors as opposed to time, the place it's the reciprocal of the slope, 1/k.
