Record films must be stored under “archival” conditions as stated in ISO 18911 and outlined in pertinent ANSI Standards and in IMAGELINK Publication D-31. These conditions include storage at 21°C (70°F) and 15 to 40% relative humidity, air conditioning to avoid temperature and humidity cycling, and clean air. In addition, the film should be stored in the dark in approved light-tight containers. These conditions will extend the film’s lifetime to be a minimum of 100 years.
