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.
