Storage Calculator for Acetate

Estimate the effects of temperature and relative humidity on fresh and degraded acetate film. Fresh acetate refers to acetate film newly processed. Degraded acetate refers to acetate film at the onset of vinegar syndrome (A-D Strip level of 1.5). Refer to the IPI Storage Guide for Acetate Film for more information.

Note: We are aware of a calculation error for fresh acetate when the temperature scale is in Celsius. In the meantime, please use Fahrenheit while we work on fixing it.
