The above chart can be used to determine
other development time/temperature
combinations that provide equivalent
photographic quality. Temperatures between
90 and 100°F (32 and 37.8°C) are optimum
for total system performance.
After-Process Information
Keeping
This film is suitable for archival keeping when processed as recommended. However, due to possible
variations in conditions, it is recommended that users establish their own compliance with existing
archival-keeping requirements as outlined in pertinent standard ANSI/NAPM IT9.1-1996, ISO 10602 -
1995, and in Kodak Booklet D-31. This film is within thiosulfate limits for microfilm, when processed
according to manufacturer’s recommendations.
