The optical density of the processed sample is measured by a densitometer calibrated with a national standard visual diffuse transmission density sheet. The characteristic curve is drawn with the density value as the ordinate and the logarithm of the exposure as the abscissa. 5.1.7 Obtaining photographic performance data
5.1.7.1 The gray fog density (D) is the difference between the optical density value of the photosensitive test piece after washing under the specified conditions and the optical density value of the test piece directly fixed without being processed.
5.1.7.2 The contrast coefficient (2) is the slope of the straight line of the characteristic curve, that is: y = tga
The angle between the extension line of the straight line of the characteristic line and the abscissa. Where a—

corresponds to the exposure that produces the gray isodensity plus 1.0 density value. Where 1(%110)-
5.1.7.4 The density at the end point of the straight line (Ddo) is the density value of the highest point of the straight line part of the characteristic curve. 5.2 Determination of uniformity (AD)
Perform according to ZB G 80001.
5.3 Determination of resolution (h)
Perform according to GB9015, in which the development process shall be carried out in accordance with the provisions of 5.1.4 of this standard. 5.4 Determination of melting point of emulsion layer
Perform according to the provisions of GB6843.
5.5 Determination of the curl of the film
In accordance with the provisions of GB 684.7
5.6 Determination of the thickness of the film base, emulsion layer and anti-halation layer In accordance with GB 6845, the following treatments should be performed on the sample during the measurement process: (. 1)
After measuring the total thickness of the film, drop protease or 5% sodium hydroxide solution on the emulsion layer of the sample. The measuring point should correspond to the second measuring point, and then scrape off the emulsion layer with a horn spoon, rinse with water, and test the sample thickness after drying in a ventilated place. The difference between the two numbers before and after is the thickness of the emulsion layer at each point. The average value is the thickness of the emulsion layer of the film, and then measure the thickness of the anti-halation layer according to the above method. After removing the emulsion layer and the anti-halation layer, directly measure the thickness of the base. 5.7 Inspection of performance in use
5.7.1 Inspection of raw film
