This standard specifies the technical performance, test methods, inspection rules, packaging, marking and storage and transportation conditions of ISO400/27 black and white panchromatic photographic negative film.
This standard is applicable to ISO400/27° black and white panchromatic photographic negative film. The film is supported by gray-blue-purple transparent triacetate cellulose base, coated with panchromatic gelatin silver halide emulsion on the base layer, and coated with antistatic lacquer layer on the other side of the base. I50400/27 black and white panchromatic negative film is suitable for photography under weak light or high-speed photography, and is mainly used in news, sports, scientific research and medical and health fields.

5.1 Determination of Photographic Performance
5.1.1 Sensitivity
The sensitivity shall be determined in accordance with the provisions of GB2923. 5.1.2 Fog density
The optical density of the exposed test piece after development and fixing is obtained by subtracting the optical density of the unexposed and directly fixed test piece. 5.1.3 Maximum density
The density corresponding to the highest point on the characteristic curve minus the optical density of the directly developed and fixed test piece. 5.1.4 Latitude
The absolute value of the difference between the logarithmic values of the exposure corresponding to the starting point and the end point of the characteristic curve. 5. 1. 5 Effective latitude
The absolute value of the difference between the logarithm of the noise light corresponding to the point where the fog density plus the base plus (.1) of the characteristic curve and the logarithm of the exposure corresponding to the point where the slope of the shoulder of the characteristic line is 0.4 is the effective latitude. 5.1.6 Determination of resolution
The provisions of GB9015 shall be followed.
5.2 Determination of physical properties
The determination of the melting point of the emulsion layer shall be carried out in accordance with the provisions of GB.6843. 5.3 Determination of performance
5.3.1 Inspection of raw film
Take a strip of standard film and inspect it under natural light. The quality of the raw film shall meet the requirements of 4.1.1. 5.3.2 Inspection of transparent film
Take a section of raw film without exposure, and then develop and fix it to obtain a transparent film. Visually inspect the transparent film. Its quality shall meet the requirements of 4.4.2.
5.3. 3 Gray film inspection
Take a section of raw film and evenly expose the layer, and develop it to a density of 0.9~1.1. Visually inspect the gray film. Its quality should meet the requirements of 4.1.3. 6 Inspection rules
Film shall be inspected according to the following provisions.
6. 1 Inspection
6.1.1 The quality of the film produced shall be subject to factory inspection according to the provisions of 6.1.2. Only qualified products can be shipped. Inspection shall be carried out in accordance with the provisions of Section 5 of this standard

6.2 Type inspection
ZBG81005-88
Inspection batch
Each emulsion number is a batch
|tt||Quantity of random inspection
At least 5 copies of different axis numbers shall be inspected
Type inspection items shall include resolution. The requirements for type inspection shall be carried out in accordance with GB1.3. Preparation
6.3 The acceptance unit generally accepts the product based on the certificate of conformity. If there is any objection to the product quality, it has the right to conduct random inspection on the batch of products. The random inspection shall be based on the emulsion number (axis number) as the inspection batch. The inspection shall take samples from any outer packaging box of each batch of film. At least 3 rolls of standard specification film shall be taken from each box, and at least one roll of reel film shall be taken from each box. The outer pattern shall be removed and the sample shall be cut. The inspection shall be carried out in accordance with the provisions of 4.1~4.2 of this standard. 6.4 If the inspection is qualified, the film of the batch number shall be accepted. If any item index fails, double the sample shall be taken and the unqualified items shall be re-inspected. If the re-inspection is qualified, the film of the batch number shall be accepted; if the re-inspection is still unqualified, the batch of products does not meet this standard. 6.5 Films that have been accepted by the user department, under normal transportation, storage and use conditions, within the warranty period, can be exchanged or returned according to actual consumption or the entire batch after verification by both parties if there are indeed problems with the film manufacturing quality. 7 Packaging and marking
7.1 The packaging of the film must be light-proof and moisture-proof to ensure the safe transportation and storage of the product.
