3-50. TIME COMPENSATION FOR TEMPERATURE CHANGES
a. Processing solutions should be maintained at the optimum 68F, but some
compensation can be made for temperature variations within limits by increasing or
decreasing the time of development in accordance with Table 3-3. For the higher
temperatures, shorter developing times are required, while for lower temperatures,
longer times are necessary to maintain uniform radiographic density.
b. The ideal method is to use the time-temperature system that accurately
compensates for temperature differences with the correct time of development. X-ray
film may be developed satisfactorily without special treatment at any temperature
between 60and 75F as long as the temperature differences are compensated for by
appropriate developing times. The lower temperatures in this optimum range, although
permitting shorter development times, are closer to the zone in which processing
defects may begin to appear on the radiograph.
