The difference between the optical density of the exposed test piece after development and fixing and the optical density of the undeveloped and only fixed test piece is expressed. b. Sensitivity
Calculated according to GB2923,
Tolerance and effective tolerance
Tolerance is expressed by the absolute value of the difference between the logarithmic value of the exposure corresponding to the lowest point and the highest point of the straight line of the characteristic curve, and the effective tolerance is expressed by the absolute value of the difference between the logarithmic value of the exposure corresponding to the point on the characteristic curve where the fog density plus the base density plus 0.1 corresponds to the logarithmic value of the exposure corresponding to the dotted point on the shoulder of the characteristic line with a slope of 0.4. 5.2 Determination of uniformity
According to the method specified in ZBG80001
5.3 Determination of resolution
According to the method specified in GB9015.
5.4 Determination of root mean square granularity
According to the method specified in GB10558.
5.5 Determination of optical density of film base
ZB G81011—90
Take a test piece of about 30cm long, remove the emulsion layer with 5% sodium hydroxide solution, and measure the density of the base film. The measurement points shall not be less than 5, and the result shall be the half mean.
5.6 Determination of fixing transparency time
Put a test piece of about 30cm long in D.1 fixing solution with a stirring temperature of 20±3℃, and start counting the time until the emulsion layer becomes transparent.
5.7 Determination of melting point of emulsion layer
Perform according to the method specified in GB6843.
5.8 Determination of water absorption
Perform according to the method specified in GB0860
5.9 Determination of scratch resistance during film processing
