参考温度Reference temperature:25°C You may over rule the referention temperature Reference relative humidity:53% RH You may over rule the referention relative humidity 菲林长度Film length:
660mm Fill out the film length at reference conditions
温度膨胀系数
Temperature expansion coefficient:18µm/m °C Default value for silver halide film
Relative humidity expansion coefficient:
11µm/m %RH
Fill out the correct relative humidity expansion coefficient
相对湿度膨胀系数
The RH coefficient is a value between 9 and 14 µm/m %RH, depending on:
Direction of the base material (length or square to the production direction)Centre or board part of the base material RH range
Before or after processing Blackness
Dimensional change, AFTER FULL ACCLIMATISATION , expressed in µm
Remark: the calculations only applies to relative humidities between 30 and 70%With relative humidities lower than 30 % or higher than 70 % irreversable dimensional changes occur a b
